CAREER EPISODE 1 I. Introduction CE1.1 My first project experience is a project that I did while working at Qatar Building Company (QBC) when I worked as the Technical Engineer in the Estimation Department. The project was to prepare a sewer drainage line for the Public Works Authority, (PWA), also known as ASHGHAL. We had participated in the tendering process and won the tender. I worked on this project between June 2014 to December 2015.The project was located at Najma District in Doha Qatar in Zone 26. The Project entailed upgrading of the existing sewerage network in Najma area which involved the removal and replacement of 19.5km pipelines (200Ã˜ - 1200Ã˜). My assignment was to design the project and ensure the sewer was flowing uninterrupted. II. Background CE1.2 This project was awarded to rehabilitate the Existing Sewers within Doha by the ASHGHAL or the Public Works Authority, (PWA), who were the client. The project was divided into four sections namely Najma-Al Hilal(Package A) Al Arab-Al Kharaib (Package B).The other section was Najma-Al Hilal Sub (Package C) and Al Arab-Al Kharaib (Package D). The project involved the design of the main lines and branches to ensure it was allowing the flow and at the same time it was capable of handling the volume generated in central Doha. I worked on the design, implementation, and commissioning of the project. CE1.3 The goal of this project was to increase the capacity of the existing sewer so that it could serve several households. It was to replace the current new work with bigger diameter pipes that could allow the flow through gravitational force. This entailed excavating the trench and giving it gently gradient to allow the flow of waste water. The other objective of the project was to ensure the project was completed on time within the design specifications that was communicated by the ASHGHAL. The last objective of the project was to carry out the plan and commission it on time since it was overdue and it had been delayed previously. Below is the organizational structure that was used to manage the implementation of this project. Figure 1: Organization structure. CE1.4 Below is the statement of my duties as the Technical Engineer. â€¢ Designing of the sewer lines that included determination of the right diameter, the gradient of the pipe, velocity among other parameters. â€¢ Advice on the best route for the pipeline to serve more areas as much as possible. â€¢ I was responsible for the preparation of the documents and other logistics in the project to ensure the success. â€¢ I participated in brainstorming of the project after I encountered some challenges. â€¢ I made sure safety, environmental and ethical issues was followed at the site to the later. â€¢ I interacted with the suppliers on economic issues related to the supply of the raw materials needed for the site. III. Personal Engineering Activity. CE1.5 After winning the tender to rehabilitate the existing sewer within Doha C763/2, I started the implementation plan, by review the contract the contract details and preparing the most important points that were captured in it. I also assembled a strong team of engineers and technicians who further helped me in the mobilization of the resources like means of transport, excavator among others. Then I went through the standards and codes like the BS 5911-1 and BS EN 1916 that were relevant to the use of the concrete pipes. I organized a meeting with my team before moving to the site ready to execute the project. CE1.6 After the start of the project, I collected the information that was essential for the design work that included the geomorphology and ground topography of the areas where the sewer was to pass through. The other information that I collected from the owners of the sewer line was the projected volume of the sewage generated by the household that was gathered to the line. I organized all the data and came up with the implementation plan before calling the meeting to discuss the execution plan. I also reviewed the expectation of the client with my team members regarding the quality of the work and milestones that were to be delivered. CE1.7 I started the design work by identifying the best route for the main line followed by the sublines connecting the households to the main line. I also identified the location of the Underground obstructions like the power lines and water pipes. I then requested for the permission from the relevant authorities for the leeway since I didn't want to interpret existing amenities. The enabled free flow of the waste water through the pipes, and I designed the suitable gradient that allowed Natural flow. The calculations that I did during this design was the determination of the gradient or slope. CE1.8 Also, I determined the cross-sectional are of the pipes that I used for the sewer lines. The design was to ensure that it was able to a serve the volume generated from the sources. I used a combination of differential equations to solve this challenge. I used the relationship between the cross-sectional area of the pipe, flow velocity, and flow rate. I further used the Manning equation to determine the speed of flow. Below are the equations. Q = AV V = (1.49/n) [(D/4)2/3] (S1/2) (Manning equation) Q = (Ï€D2/4) V = (1.49/n) (Ï€D2/4) [(D/4)2/3] (S1/2). Where V= storm water flow velocity D = storm sewer pipe diameter S= storm sewer gradient n = roughness coefficient of pipe CE1.9 The next design that I did on the project was the determination of the diameter of the sewerage pipe for the mainline and the connections to the individual households. I had selected the concrete pipes due to its strength and the ease of installation. I determined the peak flow rate of the sewer to ensure that it was able to handle wastewater that was being generated. I used below equations to determine the peak flow rates Pmax/min.t=(Pmax/minhr-t-avghr) (Pi-avgd) Where; Pmax/minhr-t-avghr=(Qmax/minhr.-tQavg-hr) (Qmax/minhr.-t) = the average flow during a duration (t) hours Qavg-hr = the average hourly flow for that day of record. CE1.10 I encountered the challenge when I was doing the excavation of the trench to lay down the concrete pipes where I found there was a lot of the underlying cables and the asbestos pipes. Besides, I discovered that the existing roads in the area where pipes were passing were not wide enough. Some of the areas were also narrow for the passage of the excavator that I was using. Therefore, I did analysis and discussed with my team where I proposed the hand excavation of this areas. The process was slow, but at least it was preferable because of the existing infrastructure. CE1.11 I completed excavation then removed and replaced approximately 2.5km trunk sewer gravity mains comprising VC pipelines (300mm Ã˜ â€“ 1000mm Ã˜) and associated manholes. I also did the replacement of 1km trunk sewer gravity mains that consisted of the GRP pipelines with diameters of 1000mm and 1200mm and utility holes on this section. Finally, I did the test run with water before filling back the top soil that I had excavated with my team I also reinstated the landscaping, paving blocks and asphalt. CE1.12 To easy the installation work, I innovatively choose reinforced concrete pipes that were one-meter-long, and it had a socket on one end. This made it easy for installation and lifting them in place. The assembling method was the socket connections and did not require any particular joining method as compared if the PVC pipes were used. This innovative approach reduced the sewer line installation time CE1.13 The useful software that I used in the project was the AFT Fathom, which is system modeling and pipe flow analysis software. I used to this software to calculated the flow distribution and pressure drops in the pipeline. Furthermore, the software was usefully when I was analyzing the distribution of wastes in the pipe. The software eased my work and improved on the accuracy of the project. CE1.14 With other members, I was able to work towards completing this task on time. The implementation team that I led consisted of both engineers and technicians. I consulted a senior technical engineer when I encountered some challenges in my projects and when I was participating in the tendering process. The other person who was worked closely was the quantity surveyors who were responsible for the BOQ for the project. I organized meetings on regular basis with the team to review the progress of the projects. CE1.15 My other responsibility as the team leader in the project was the preparation of the projects documentations for records keeping and as the mode of communication. I used the English language on this project to avoid language barriers because workers in the project were from different ethnic background. The documents that I prepared included the tender documents, project progress reports, weekly reports among others. I also did the presentation of this documents to my supervisor before it was approved for circulation. CE1.16 As the team leader in the project, I participated in making a decision that helped in reducing the cost of the project or at least working as per the budget. Therefore, from the start of the project, I developed my budget and came with some ways of reducing the cost by maximizing the productivity of every worker. This saved on the salaries and allowance that was paid to the casual Labour on site. CE1.17 With my project management skills, I was able to ensure all the plans went on through the project implementation time. I also used the traffic master plan when the was excavation near the road where the sewer line was passing through. I had developed the implementation plan that guided me in the budget and the millstones that were to be achieved at every stage of the project. CE1.18 At the time of the project implementation, I applied my skills in fluid mechanics to do the project. I also participated in the training that was offered by the company. The training was on simulation and how to lay pipes on the trenches using lifting machines. I also had some discussions with the senior members in the company who they shared their experiences in piping work. Lastly, I researched on my own whenever I encountered the challenge that was related to the project. CE1.19 I understood the importance of taking safety while implementing the project because it could cause adverse impacts to both implementation team, environment, and tools. We used the lift tools instead of manually lifting because of dangers in the back injuries. The other safety precaution that I took was to use protective equipment like safety boots and gloves. I also followed the user operation manuals for the lifting tools that we were using at the site to avoid damages and associated injuries. IV. Summary CE1.20 I completed this project on time and gained tremendous engineering experiences concerning team leadership and technical knowledge. I managed to lead the implementation team from beginning up to completion. Therefore, I achieved the goals of the project that included upgrading of the pipeline and completing it within the planned time. I played a significant role in the project from the beginning where I did the design, coordinated the implementation and commissioning. In the end, all the members of my team and management were happy with the way I implemented the project successfully. CAREER EPISODE 2 I. Introduction CE2.1 The second project discussion is my Engineering experience that I acquired while working as the Technical Engineer at Qatar Building Company (QBC). This project was the participation in the construction of the Al Otouriyah / Al Jemailya / Al Shihaniyah Road (P019) where I performed the Soil test that I will elaborate on the project. I worked and delivered this project within 18 months between November 2014 to May 2016.The project was located in the central region of the Qatar, where 28.7km of Rural Arterial road from Al Shihaniyah to Al Jemailya via Al Otouriyah. My responsibility was to perform the soil test that enables the determination of the amount of compaction and the to check whether the soil was able to current the maximum required loads. II. Background CE2.2 Qatar Building Company (QBC) is the market leader in civil engineering and building, and it was awarded the contracted to construct by road by ASHGHAL or the Public Works Authority of Qatar government, (PWA). The project was the design, and its implementation monitor by ASHGHAL. The road was divided into two sections namely 18.8 Km between Al Otouriyah and Al Jemailya. The second section was the 12.6Km between Al Shihaniyah to Al Otouriyah. The project that I did this construction work was the earthwork where I perform the various soil test to ensure compaction was done well. I implemented the project and made recommendations as per the test results. CE2.3 The goal of my engagement on this project was to upgrade the existing two-lane single carriageway (1 1) to a four-lane dual carriageway (2 2). There was also a provision of the cycle lanes that was reserved for future expansion to six carriageways (3 3) lanes. Because of the scope of the project, I participated in the earthworks that involved compaction and testing the strength. The objectives of the compaction soil test were to verify the strength of the road base the before the paving to make sure it was able to carry design loads. The other aim was to advise on the mixing combination in areas that did not yield the required test. The last goal of the project was to make sure the road was done as per the codes and standards that were mentioned in the project contract. Figure 1: The organization chart used CE2.4 Below are the roles and responsibilities that I was assigned as the Technical Engineer. â€¢ Participated in the design of the road especially the stabilization of the base foundation. â€¢ I did the soil compaction test and advice the earthworks team where necessary. â€¢ I was part of the project planning team where I came with the implementation plans and ways of mitigating challenges that I encountered in my line of duty. â€¢ I did the compaction test calculations where I was able to determine important test parameters that helped me in making the informed decision. â€¢ As the team leader in the soil compaction test, I prepared and presented various documents to the stakeholders. â€¢ I ensured safety was maintained at the workstation and ensured the dust was not affecting the surrounding environment. III. Personal Engineering Activity. CE2.5 We moved to the site after the company won the contract and after completing all the logistics work. To understand the project, I went through the contract that specified the scope and the timeframe for the project. Besides, I went through the applicable codes and standards that were mentioned in the contract that includes the standards as per ASHGHAL. Also, the California Bearing Ratio (CBR) that I did was as per the AASHTO T193, D4429 and D1883-05. After assembly my team I met with the Engineering manager who we discussed what was expected of me as the person who was responsible for the soil compaction testing. CE2.6 Before I started the project, I listed down the details of the information that I wanted to initiate the implementation of the project. Some of the information was the test method that was expected, the reporting structure concerning conveying data for the purpose of action among other. The technician whom we worked together collected samples randomly from the road sections that had been compacted. Lastly, I organized meeting with my team members who we discussed the testing procedure that I adopted. CE2.7 The first Engineering work that I did while constructing the road was to ensure the road foundation was done correctly. The road foundation was done by mixing deferent soil mixture and compacting using a roller to form layers. To ensure that the compaction was done properly I did the soil test using various methods. I instructed compaction to be done until the required compacted soil was achieved. The soil compaction test that I used were sand cone method, California Bearing Ratio, and the Soil Permeability. CE2.8 While doing the California Bearing Ratio, I determined the quality of strength of the soil that was to form the base of the soil. I also measured the thickness of the base compacted soil and the layer. I performed this test by using a plunger with the standard area and measuring the pressure required to penetrate the soil. I then divided the measured pressure with the required pressure to achieve equal penetration on the norm crushed rock material. Below is the formula CBR = F/Fo where F = force needed to penetrate a soil mass. F0 = force necessary for the penetration as per the standard material. CE2.9 The other test that I did was the sand cone method and the Soil Permeability to ensure that the compaction process was done well. The purpose of the sand cone method was to determine the field density. For the ground permeability test, I used Darcyâ€™s law as shown below. V = kiA where V = Flow rate cm3 /s, A = cross-sectional area of soil conveying flow, cm2 k = permeability Coefficient CE2.10 After completion of the compaction of the base soil, and ensuring the road could sustain the design loads. We lay down the asphalt pavement in that contained approximately 313200-ton asphaltic concrete followed by 244,224-ton Polymer Modified Bitumen asphalt in various layer thicknesses. The other part of the road that we did was the pavement where interlocking blocks was used. Besides, the streets light was erected. We also made the road making and built the road signs to guide drivers while navigating the new path. We commissioned the project with my team and client after completing all the work that was stated in the contract. CE2.11 I encountered a technical challenge when I was preparing the granular road base layers and sub base whereby on doing the laboratory test I found that the materials did not meet the stipulated sand equivalent ratio that was 25. After researching for the best solution, I discussed with the quality manager and agreed to do different mix gradations, and I also added the Gabbro aggregate fines that helped in meeting the proposed mix in of sand equivalent ratio. In the end, I managed to achieve the equivalent sand ratio of 32 that was good enough for the project. CE2.12 To improve the quality delivery, I tried to be creative by following the company IMS Policy when I was working with subcontractorsâ€™ also followed the Quality & HSE to ensure the quality was maintained. On the design work, I made the decision to use three different compaction test methods to improve the reliability of the results and reduce the chances of the errors that are associated with soil compaction test. I also did the test on the rolling basis to ensure we deliver results on time without any delay. CE2.13 I leveraged on latest technology during the execution of this project regarding tools that I was using. For example, I used GEOSYSTEM programs software that helped me in plotting boring log, and the test pit logs that helped me in reducing the time taken in reporting test results for the geotechnical test. The software also helped me in the analysis of the cement products and concrete test results. This program supported the AASHTO, ASTM, and ACI standards. CE2.14 I was a member of a team during the implementation of the roads construction works, and I was appointed the team leader when we were doing the road compaction test. As the team leader, I helped in guiding the technicians on how the test was performed. As the team leader, I maintained the flow of communication and gave the feedback to the management who lead the road construction works. We also worked together with subcontractors who were suppliers of the raw materials where we regularly discussed on the delivery lead times. CE2.15 As the team leader in the compaction soil test, I was tasked with the production of different types of reports that I share with the client and the company head office. These reports were important because it determined the compaction required which is normally associated with the cost. The other documents that I prepared with my team included the analysis reports, weekly progress report among others. The language that I used on this documents was English since that was the official communication language at the site. CE2.16 I made the economical decision during the implementation of this project because I always interacted with the suppliers of the soil compaction equipment. I always when for the most affordable but reliable option regarding hardware and test. Besides, as the team leader, I negotiated the project manager to allow my time work extra few hours to cover lost time. This reduced the overall cost of the project since it was billed as per the number of days spent at the site. CE2.17 Project management was a core part of the project because without it tracking of the progress could not have been possible. There with my skills in project management, I was able to plan the section that I was working on in the road project. I came with the work breakdown structure where I disintegrated all the soil testing procedure into subtask that I allocated my team members enabling me to monitor and track the progress well. CE2.18 To enhance my work delivery, I participated in self-study by studying various methods used in geotechnical test and their advantages and disadvantages. Also, I applied my knowledge that I acquired in university in areas like the soil mechanics for geotechnical investigation and analysis. The other skills that I used were the engineering soil properties that gave me knowledge in the standard soil test methods. The last application of knowledge that I involved in the project was the different road profiles that I learn during the study of the construction drawings in my undergraduate degree. CE2.19 Safety and sustainability were a paramount part of the project because it was the best way of mitigating the dangers associated with Road construction. For safety reasons, I protected and stored all the test samples in the secured place to ensure there was no contamination. I also used protective gear during the execution of the project by wearing safety boots, helmet, and gloves. I also considered the environmental hazards associated with roads construction by spraying water regularly to the excavated earth to suppress dust. Lastly, as an ethical engineer, we maintained good working relationship with everyone in the project and the neighborhood where we organized football games with the young kid in the surrounding. IV. Summary CE2.20 The scope of the project was huge, but I leveraged on teamwork and my good research skills. The project gave me a lot of experience in road construction and tested my ability as the team leader. I completed my project after successfully meeting the objectives of the project and after completion of the road construction work. The project met with the international roads standards, and the law stated in Qatar and Ashghal requirements. My contribution was significant as per the statement of my responsibilities and the quality of the work that i did with my team. CAREER EPISODE 3 I. Introduction CE3.1 My third project discussion is the experience that I acquired while working on the extension of Highway 55 temporary truck route section B and A. At the time of this project I was working for Qatar Building Company (QBC) as the Technical Engineer. This project consisted of the constructing 22.7 KM dual carriageways with four bridges, seven roundabouts and other associated amenities like diversions that ensured the flow of traffic. I worked on this project between November 2013 and January 2015 at west and north of Doha City. The work was divided into Sections A and B for Route 55 Temporary Truck Route (TTR). As the Technical Engineer, I was tasked with designing and ensuring the road was done to the right standard. II. Background CE3.2 QBC was established as a private civil engineer contractor in 1971 as a private civil engineering contractor in Qatar. It has cemented its position as the Civil engineering contractor, and it further introduced a new line of service called the Qatar Building Company Heavy Equipment Division that deals with construction equipment. This project was as a result of the tender that QBC had won after it was selected by the Ashghal to construct the road extension of the Highway 55 Temporary Truck Route of sections B and A. The project involved the supply of the civil engineering raw material and implementation of the traffic management plan. The other work included the re-routing of the power lines that was on the construction site and the design and construction of the Asphalt paved road. The other work that I did on the project was the design of the bridges and the drainage systems along the roads. After every section during the compaction of the base foundation, I did both penetration and compaction test to make sure the road was able to carry the design loads. CE3.3 The aim of the project was to extend the Highway 55 and construct the Temporary Truck Route through Section A and B. With my civil engineering skills, and I ensured the project was implemented within the standards. I made sure the raw material used were acceptable. I also performed random penetration and compaction test to ensure the road was done as per the standards applicable in Qatar. The other objective of the project was to provide the basic outline of the resources that was required to implement the project. The design was also to allow the smooth flow of the traffic. Thus I introduced some roundabouts to enable vehicles to move from one side to another without creating some congestion. The last objective of the project was to design and construct Bridge that was able to withstand all the loadings acting on it. Figure 1: Organization Chart CE3.4 As the project technical civil engineer, I was assigned the following roles and responsibilities. â€¢ I participated in the design of the road constructions, such as coming with the specifications like the compaction pressure, the number of roller passes, the thickness of the pavement layers, the excavation and fill volume among others. â€¢ I performed the both compaction and penetration test followed by calculations so as to ensure the road was done to the design specifications and was able to carry the design loads. â€¢ I enforced the Roads constructions standards that were necessary for Qatar approval. â€¢ I optimized my designs by using the latest civil engineering software. â€¢ I was the team leader who made sure that the members were doing the right things. I also implemented safety on behave of the client. â€¢ I managed the project through planning, implementation, monitoring coordination among other areas. III. Personal Engineering Activity CE3.5 As the Technical Engineer and after being appointed to be part of this project, I started by reviewing the contract to understand the project details like the scope of the work and responsibilities of every contractor in the work. I also went through the road design and the specifications to acquaint myself. Then I took two weeks to move to the site and set the base and to assemble my team that consisted of Civil engineers and other technicians who were experts in road construction. I also went through the standards and codes that I followed in the project to meet the international standards such as the Qatar National Construction Standards 2010, ASTM Standards D1883-05, AASHTO T193, and BS 1377. I then held meetings with the Project Engineer who we had the last briefing. CE3.6 I started the project by collecting the information that helped me in the implementation process. The data that I gathered on this particular project included the compaction passes that was to be used, the paving raw materials and the procedure used to test and analyze the road to ensure it was done correctly. I also collected information such as the mass of the sample, the volume of the mold and the water content in the sample that helped me when I was doing the compaction test for the samples that I had collected from the site. Then I came up with the implementation plan where I determine the key performance indicators, roles, and responsibilities of everyone, budget and the millstones that were to be achieved at every particular time. CE3.7 I reviewed the tender documents to make sure that I considered all the requirements on the project such as the design, implementations, materials used and tests to check the quality of the work. I made the approvals of all the materials on time to avoid the delays that could have happened to the project especially for the material with long lead times like the retaining wall face panels and the bridge deck. I issued various site instructions to the members of my team during the excavation, filling, compaction and paving using the bitumen. I did multiple tests on random sections of the road during every stage of the project implementation and determined their parameters through calculations followed by comparison with internationals standards. CE3.8 The other duty that I was assigned during the implementation of this project was performing the penetration test to determine mechanical strength of the new carriageway constructedto ensured that it was able to carry the design loads. I did this important test called the California bearing ratio(CBR) by measuring the pressure that was able to penetrate the tarmacked road using a plunger of the given area. I did this test under the ASTM Standards D1883-05, AASHTO T193 and thein BS 1377. During this test, I did the calculations that helped in the determination of the CBR using below formula. p= measured pressure for site soils [N/mmÂ²] ps= pressure to achieve equal penetration on standard soil [N/mmÂ²] CE3.9 I also calculated compaction density for the already paved road to ensure that it was able to carry the loads from the vehicles moving on it. I used the information that I collected with below formula to determine the densities that were important in the determination of the road compaction. Bulk density, P=M/V Dry Density, Pd= P/(1 W) Where; M=Mass of the sample(grams) V=Volume of the mold(ml) W=water content of the sub-samples CE3.10 The difficulty that I encountered during the implementation of this project was when I realized the CBR value on the proposed existing road ground was less than 15% that I measured at 95% of MDD. As per the Qatar Standard Specifications, the values of the CBR for the existing ground ought to be higher than 15% so as to receive permanent road layers. To solve this technical challenge, I researched online and consulted my friends and senior members of the company and came with the suggestion of excavating some portion. Therefore, I excavated 300mm thickness of weak topsoil and filled it before doing the compaction of the layers less than 150mm thickness so as to meet the requirements of the CBR value. CE3.11 After completion of the compaction and penetration tests on every section of the road and at different stages, I prepared short reports that I shared with the project engineer who was heading the project. I also kept the test samples with the name tags for future references. Lastly, I held discussion with the implementation team to ensure that the compaction and ingredients mixing was done correctly. CE3.12 I embraced the innovative technique, in the way, I implemented the project, for example, I discussed with other engineers, and they agreed to work on sections until it was completed then move to another section. This prevented the suffering of the motorist who needed only to pass through diversions. The other innovation that I introduced was the use of the softwares that tremendously improved on the design accuracy. CE3.13 As an engineer who values new technologies, I adopted the application of engineering software during the implementations of my road design and construction project. The software that I leveraged on is AutoCAD Civil 3D, Micro station, and the AutoTurn. This softwares gave me the edge during the implementation process because I was able to cut the delivery time and I was also able to do the design optimization. CE3.14 As shown by the scope of the project, there was a lot of work; therefore, teamwork at the site provided the solution. Therefore, I organized a team consisting of technicians and engineers who we worked together. I discussed and reviewed the site progressed with my team members. As the team head, I tasked every technicians and engineer who were working under me. CE3.15 I created various documents at different stages of the project for the purpose of records keeping and channeling information to other stakeholders. For example, after compaction and penetration tests, I documented the procedure that I used plus the outcome results. The other documents that I prepared include the progress reports, weekly reports, and monthly reports. I used the language that was understood by everyone at the site thus I avoided the language barriers. CE3.16 I interacted with the suppliers of all the raw materials that was used at the site; thus I was able to make economic decision based on the goods that was purchased. For example, I negotiated for the discount since I instructed the procurement department to buy the materials in bulk thus we were given discounts. There other are that I made an economic decision was when I requested and negotiated with the client to allow us to work for extra one hour every day and shorten the delivery time. This saved some money since the payment was pegged on the number of days worked and not the hours. CE3.17 With my skills in project management, I was able to track the project progress using the MS project where I was able to come up with the work breakdown structures (WBS). With this skill, I managed my project very well and planned accordingly especially for the task that was dependent on others. With this knowledge and expertise, I was able to monitor the project implementation process that led to cost minimization. Besides, I was able to develop Gantt chart that I used to illustrate the project schedule that was easy to be followed by my team. CE3.18 During the implementation of this project, I took some initiative to improve my skills in the delivery of this project apart from the skills that I acquired in my engineering school. For example, I did self-study and research online on the various methods of performing the compaction test in the tarmacked road like this project. Apart from that, I applied the knowledge that I acquired in my undergraduate degrees such as the Highway and Pavement Design, Transportation Engineering, Soil Mechanics, and Design of bridge structures. CE3.19 I put safety in the forefront in all the activities that I did at the site to avoid any form of accidents that could have jeopardized the project implementation. Therefore, I ensured all the workers were supplied with the protective gears like the safety boots, coverall, and helmets. Besides, I followed the correct operation procedures for the tools and equipment to avoid any breakage. Lastly, I protected the environment and ensured the project was sustainable by preventing pollution. IV. Summary CE3.20 In my view, the project gave me valuable experience and improved my engineering knowledge because I was able to lead the design team. I was also able to make decisions and research on the project when I encountered some challenges. The project was successful despite the technical problems that I faced.

Onvis Security Alarm Contact Sensor (evaluation) - camera ip hải nam

Onvis Security Alarm Contact Sensor (evaluation) - camera khu00f4ng du00e2y hu1ea3i nam With the recent news that the Abode Iota hub/Camera has ended up being HomeKit suitable, which likewise consists of an alarm system, the idea of shielding one's home-- by means of HomeKit-- has come forward again in many peoples' minds. Obviously, this isn't something brand-new, but with the aforementioned Abode, as well as Honeywell being quite costly for some, or perhaps even overkill if you're living in a small apartment or shared holiday accommodation, camera khu00f4ng du00e2y hu1ea3i nam so tools like the Aqara hub with its integrated alarm have actually been of interest to the budget-conscious. When it concerns tight spending plans, this brand-new gadget from Onvis-- the Security Alarm Contact Sensor-- may be things some are looking for, with a consolidated get in touch with sensing unit and alarm, as well as a number of various other sensors included for good step, and no need for a center. However can a budget tool with whatever tossed into such a tiny device be any kind of good? Let's learn. PRODUCT PACKAGING. Front of box. Side of box with specifications and demands. Side of box with symbols for standard functionality. Normal readers of my reviews will understand I appreciate decent packaging, as high as I dislike inadequate packaging, and also I'm delighted to claim this lands in the former group. It genuinely is a 'box' in regards to the very thick, sturdy card (like the kind you would certainly get for an iPhone) that's utilised, so the dainty little gadget within is well safeguarded. The front is straightforward sufficient, with the item envisioned along with the ever before encouraging Apple HomeKit logo design. The rear is all about the fine print and also isn't really of any major interest. One side of the box provides you a couple of symbols indicating the fundamental features of the device, whilst the opposite goes into specifications and also requirements;. Safety alarm system-- Adjustable alarm system approximately 120dB. Four alarm system settings-- Home, Away, Night, Off. Get in touch with sensor-- Detect on/off standing of your door or window from anywhere. Notices-- Sends notices to your tool. Temperature/Humidity-- Shows temperature level and humidity for the location where the alarm is based. House automation-- Create personalized automations as well as scenes to manage your residence with any kind of HomeKit enabled devices. In regards to specs and also needs, the device utilizes two AAA batteries, with a standby time of 1.5 years, and also Bluetooth LE 5.0 as its approach of communication. They recommend that you're going for the very least iOS12.1, as well as if you desire remote accessibility or create scenes and automations, you'll need a Home Hub, like the Apple TV4 (or higher), a HomePod, or a suitable iPad that's completely powered and linked to wifi. All rather typical stuff. You'll require to download and install the Onvis application for accessibility to certain setups and updates, although aside from these, you don't need to make use of the application for anything else, so you can use the Home application or various other 3rd celebration applications, like Eve, as I'll describe later. Alarm, magnet as well as batteries. Extra 3M sticker labels, guidebook, screws as well as a customer support card. As soon as the box is opened, you'll see a little bag of contents, that includes the handbook (all in English) consisting of HomeKit code, a spare set of double-sided 3M stickers, a set of screws with rawl plugs, and also a client service card. Underneath that is the gadget itself-- The alarm/sensor, the going along with magnet and also 2 AAA batteries, all securely held in location with extremely dense foam. Equally as a side note, the batteries in the photo above will certainly more than likely vary from your own, as batteries weren't supplied when Onvis sent the tool to me-- delivering concerns evidently-- so I give these myself. THE DEVICE. Alarm/sensor and magnet. Side of alarm/sensor. Opposite side of alarm/sensor with HomeKit code. The Alarm/sensor is made of very shiny white plastic as well as has the alarm audio speaker precisely the front, with the Onvis logo design directly below. When the door sensor is triggered, below that is a hidden LED that blinks. Near the bottom is a reset button, need to you need to get the gadget back to factory settings. When I initially saw this tool online, I really believed it was bigger, yet it's actually not as big as I assumed. The primary sensor is 90 x 38 x 21.4 mm/ 3.54 x 1.49 x 0.84 in. The magnet component has to do with a third of the size, at 34.9 x 15.7 x 14.8 mm/ 1.37 x 0.62 x 0.58 in. Base of alarm/sensor. Leading of alarm/sensor. Around the body of the main device are openings, which I can just assume are 2 permit the dimension of temperature level and also humidity. Yes, not just does this have a call sensing unit with an integrated alarm system, however it additionally includes temperature level and moisture sensing units. This may seem a little bit strange, as well as I 'd possibly concur that it appears a little bit unjustified, yet if you don't already have any of these sensors, after that it does offer a lot more worth for cash, although if this is situated on your front door, I'm unsure how vital readings of these kinds would certainly be. I presume it's all to placement. This is also the instance with Onvis' various other HomeKit device, the SMS1 Motion sensor, which also has temperature level as well as humidity sensors integrated. You can review our testimonial of the SMS1 below. Alam/sensor and also magnet, with markings for proper positioning. Alarm/battery area. Both the main sensing unit and also the coming with magnet have an indented circle on one side to reveal where the sensor as well as the magnet need to line up. The hand-operated states that the void between both requirements to be less than 20mm/ 0.79 in. Initially, I thought this was in referral to the distance in between the two parts once they would certainly been placed on your door, with the door closed, but it, actually, indicates that both circles need to align to within 20mm of each other in the upright airplane, so if for any reason you're not able line the circle markers up exactly, then attempt to guarantee they're within the 20mm limitation. No matter this, it's always excellent method to keep the sensor and also magnet near. The battery compartment holds 2 AAA batteries and also is typical besides the reality it's really easy to open up and close. I 'd probably state also easy in some areas, and also it probably would've been a great concept to include a tiny screw that quits the door from being slid off so easily, in similar way that some video clip buzzer video cameras can be protected. Despite it just being utilized for inside your home, there could be a circumstance where somebody does manage to get into your home, but isn't discouraged by the alarm system and is rapidly able to deactivate it by taking the batteries out extremely quickly, which a protected screw would stop or at least seriously slow such an attempt down. Obviously, you would certainly obtain the notification, yet if you're far from home and also you're wishing the neighbours are paying attention, it's entirely possible that the alarm system would certainly get overlooked if it only blasts out for a few secs, with some individuals simply assuming the alarm was set off inadvertently. In a lot of situations, a prospective burglar would certainly hightail it out of there as soon as the alarm system is set off, so the possible circumstances mentioned is perhaps an extreme one, although still quite possible. SETUP AND SETUP. Onvis Alarm in Home app. Onvis Alarm in Onvis application. As the device is a fully-fledged HomeKit offering, you can just add it to the Home app in the same way you would any other. Nonetheless, much like other HomeKit gadgets, it's also good method to have the suppliers' app for not just updates however settings that aren't always readily available in the routine Home application. As you can see in the screencaps above, once installed, the device quits 4 separate ceramic tiles, although in the Home app they will at first be packed into one tile, so you're going to need to 'unbundle' them in the setups. There's a ceramic tile for the contact sensing unit, temperature level and also humidity. Furthermore, you get the alarm ceramic tile. This is virtually the same scenario with the Onvis application, offering you 4 ceramic tiles. - camera hikvision hu1ea3i nam When it comes to tailor-making specific facets of the alarm, it's finest to do it in the Onvis application, as this is additionally where you'll be able to download any type of firmware updates (tip: there will certainly be ones waiting ...). In the settings web page, you can transform the name of the gadget, in addition to adjustment its place. You can set any of the 4 states we've already discussed-- Home, Away, Night and also Off. You can likewise set the default quantity of the alarm-- Low, Mid and also High. I've been notified that if you intend to release an external audio resource for your alarm rather than the built-in alarm, such as your HomePod as an example, the firm are functioning to add a mute choice to the alarm system settings soon. Further down, you get to be able to readjust how long the alarm system rings for, with a minimum of 10 seconds as well as a maximum of 600 seconds (10 mins). Finally, if you're in requirement of removing the device, you can do so with the help of the large red 'Remove Accessory' switch. ALARM SYSTEM MODES. Alarm states in the Home app. Alarm system states in the Onvis app. When you press on the alarm ceramic tile in either app you obtain access to the four separate alarm 'states'-- Home, Away, Night and Off. This could appear a little bit complicated to some who are simply made use of to having 'Off' and also 'Away', but essentially, these states are the starting point for your own arrangements or automations. The Onvis handbook explains exactly how they regard these different states thus;. House (it's described as Stay when you receive alerts)-- Home is occupied, and the homeowners are active. The safety and security alarm plays a 'ding dong' audio when the door opens (note: it's absolutely nothing like 'ding dong'). So, essentially this is the door not set to 'alarm system', but simply alert, so you recognize a person has come home, while you-- or somebody else-- is home. Away-- The safety and security alarm system 'beeps' (the alarm seems) for 30 seconds when a person activates the get in touch with sensing unit. The Alarm time can be set from in between 10 and also 600 secs in the Onvis app. This is the fundamental armed alarm system. Evening-- The house is occupied and also the locals are sleeping. The safety alarm system 'beeps' (the alarm sounds) for 30 seconds when a person causes the get in touch with sensor. The Alarm time can be set from between 10 and 600 seconds in the Onvis app. This is the same as the fundamental armed alarm, but as I'll describe later, they can vary. Off-- The alarm system is deactivated. Really easy. Keep in mind: At present, the 'Historic Records' switch appears to hang, although the firm have actually currently sent a fix for this, so it should no longer be a problem once the application upgrade has actually passed the common App Store review procedure. In order to get the Away and also Night alarm settings to function in different ways, you need to produce an automation that's suitable for these scenarios, although in each case, these two settings will always cause the integrated alarm. I'm going to begin with the Home app for the moment, to explain that whilst you have the four separate alarm states to select from in the Home app, you aren't able to set up external/3rd party tools to cause them because of this. This is relatively comparable to how the Aqara center operates in regards to alarm systems, in that the Home application only assists in triggering or shutting off the various modes, not configuring them. So properly, in the case of the Aqara hub, you need to set the tool that activates the alarm system (which needs to be a youngster device bound to the center-- i.e. Mijia or Aqara gadgets) in the Aqara or Mi Home application, depending on which of the two you're utilizing. In reference to the Aqara center, at present, you just have the arm or disarm (Away or Off) choices in the Home application. With the Onvis tool, this increases on what settings you intend to pick from, although it's to what you finish with those settings that make a difference. What should be understood, however, is that just like the Aqara center, only the Onvis call sensing unit can actually activate the alarm system. The large difference here is that with Aqara, you can choose your gadgets as the triggers for the alarm. As the onvis is a device unto itself, only its very own trigger tool-- the get in touch with sensing unit-- can be used. As Onvis also make a motion sensing unit, in addition to the honest HomeKit cam we pointed out a while back, it would certainly make a lot of sense to include these as extra outside trigger tools for the alarm, as well as after mentioning this to Onvis, they have actually informed me they're servicing an update to resolve this capability. With all that claimed, what can you make with these settings? I 'd prompt you in this circumstances to start considering something like the Eve app, or various other 3rd celebration applications that permit complete control of these settings in automations. I'll demonstrate why these apps are essential to attain this later on, however initially, its excellent to start describing the various settings in better detail. so for instance, you could want to either established a Scene (or automation), that sets the alarm to Away mode, (which by default arms the alarm). The scene can also consist of turning lights or heating off, naturally. For Home mode, this acts nearly the like Away mode, with the primary distinction being that whilst the alarm is 'equipped', as opposed to the piercing alarm noise being triggered when the get in touch with sensor reports the door being opened, it will certainly play a chime, which I formerly claimed was labelled a 'ding dong' sound. In actual reality, it's a little like the digital two-note beeps you might listen to if you unlock to a neighborhood corner store. This is seemingly designed to allow individuals who are currently home, recognize that the door has been opened, yet as they're home, there should be no cause for concern, as it merely notifies you that possibly your children have actually gotten back, or maybe your significant other has returned from work. You could intend to create a scene that, when the call sensor is caused under this setting, it additionally transforms one light red in the area (or areas) you invest a lot of your time in, to let you and also others recognize somebody has returned, as or else in order to be informed by the chime alone, it would certainly have to be set to optimal volume if you were at the various other end of your house. Evening setting is even more of the exact same yet is more comparable to Away mode in that if the door opens up, the regular 120dB alarm will appear. As before, it needs to be specified that so as to get a different experience from Night setting compared to Away mode, you could want to work out the proper scene and equivalent automation. So, if the alarm system is triggered in Away mode, you'll desire the alarm to activate (as it will certainly do by default), and maybe have red lights come on where the entry is, to frighten the would-be burglar. Yet, if you establish Night mode you could desire extra lights to set off possibly, like your room lights ahead on at 100% illumination, to inform you if your phone is readied to 'do not disturb' for example. The sensing unit will play a tone to allow you know when you pick any of the 4 settings in either the Home or Onvis application;. When you select either the Night or Away settings, the sensing unit will certainly give out a short single tone. If you select the Home setting, it will offer the two-tone audio mentioned previously. If you pick the Off setting, it will certainly hand out 2 brief tones in succession. CREATING SCENES AND AUTOMATIONS FOR THE MODES. Evening alarm setting automation in the Eve application. Evening alarm mode automation in the Home application. Additional automation details in the Home app. Regrettably, the Home application does not support automations that use the various modes, so it's down to the Eve application or comparable 3rd party applications to do the preliminary job. In the very first picture over, I've developed a basic automation;. If the Onvis contact sensor 'call state' is 'no' (indicating the door is open). With the condition that the Onvis alarm system mode is set to 'Night Arm'. Then trigger the 'Lights Bright' scene (this transforms the room light on at 100% illumination). As you can also see from the 3rd and also 2nd screenshots, as soon as you've produced the automation, it will appear in the Home app, practically as though it was produced there in the first place. If you take a look at the other alternatives available in both applications, you actually can develop some really intricate alarm situations, so you're just limited by your creativity and also what gadgets you have that can be included in claimed automations. PHYSICAL PLACEMENT OF THE ALARM/SENSOR. Like several call sensing units, the Onvis relies upon 2 components-- the sensor and a magnet. The magnet is typically fitted to the door jamb, with the sensor part suitable to the door. Sadly, as is additionally the case with a lot of get in touch with sensors, the magnet within the primary sensing unit is just on one side, and also when it comes to my front door, the door opens on the left from within. The link between the magnet as well as the sensor on the Onvis is on the right. - dahua hu1ea3i nam Closeup-- put sidewards at the top of the door. This indicates that in my situation (left-hand door), the sensor has to be either positioned upside down or positioned at top of the door, laterally. Neither looks terrific, as the Onvis logo design is upside down for the first option, and sideway for the 2nd. It's truly not completion of the globe, yet it would certainly have perhaps been an excellent idea for Onvis to add a magnet to both sides of the primary sensor, in order to fit door that opens up left wing as well as right. If you have a door with a large door jamb that can accommodate the text, after that it's also ok to place the sensing unit there naturally, but unless you occur to reside in a palace or castle, many modern residences and doors just have reasonably slim door jambs. IN DAILY USE. Onvis Alarm Sensor put on primary door. When I at first mounted the Onvis sensing unit, all worked out, but after the very first 24 hours, I did run into a number of concerns. The very first one associates with notices; For some reason, the Onvis was sending arbitrary alerts to my phone by means of the Home app. These notices just reported on the state of the alarm-- Away or Off for example. A colleague of mine has actually reported the very same concerns with his examination unit and also has been experiencing numerous of these alerts. In my case, it has actually been possibly 2 or 3 a day, and also as of writing this testimonial, they seem to have actually greatly stopped. The firm understand this problem, and also I'm informed a repair is virtually all set. The other issue I initially had was that the tool detached on a number of occasions. I removed and also returned the batteries and also it returned, yet what I at some point observed was that it was essentially a little also far from my apple iphone as well as Home Hub (Apple TV4K), therefore would certainly disconnect as a result of an absence of a link. I was able to simply remedy this by turning on a second Apple TELEVISION I had in the same room as the Onvis, that was previously not set to serve as a Home Hub. As soon as I did this, I have not experienced any further disconnections, which is an alleviation. It does show, nonetheless, that regardless of this being a Bluetooth 5.0 device, which must have four times the reach of Bluetooth 4.2, the reach and also signal isn't as strong as I 'd expected. Could this be an insect within the coding for the Bluetooth chip? I don't understand, yet I feel it ought to be much better, and with any luck, the company can address this if it is indeed less than it needs to be. Actually, as many people understand, there are some severe problems still to repair with the Home app in iphone 13, so it's hard to position too much blame with the tool itself, as a minimum of three times a day, I need to reboot the apple iphone in order for the Home app to behave itself, which makes screening tools similar to this even more harder, if you have not obtained an app to create a typical, steady atmosphere to check it in. Although admittedly, I'm not a substantial fan of Bluetooth devices, their Bluetooth movement sensing unit has actually been really trustworthy, and so far, since turning on the 2nd Apple TV, the Alarm Sensor has actually behaved very well also. Undoubtedly, to truly know how reliable something is in a more comprehensive sense, it takes a very long time to evaluate, but one could also say regarding the length of time one should test a device to regard it dependable-- if something is made for years of service, and also you evaluate it for a year prior to it stops working, was that enough time to consider it reputable? I'll leave that for you to choose, but also for the time being, thinking about the existing state of points, it appears suitable sufficient, especially for the rate. SUMMARIZING. - camera kbvision hu1ea3i nam I didn't have extremely high assumptions for this tool, simply based on the concept of exactly how it functions contrasted to a committed or even semi-dedicated alarm configuration. However, whilst this probably isn't appropriate for bigger house maybe, there are certain use situations for this; possibly you want to use this for a different privy or garage door (within series of program), or perhaps even a backup to a door with a sensor already in position. I would recommend that a tool like this is optimal for individuals in smaller sized apartment or condos or perhaps people that stay in shared lodging, with their very own lockable room possibly. It might also be useful in student holiday accommodation, where there often tend to be a great deal more goings and also comings. It's additionally reasonable to highlight the truth that as it's Bluetooth, there's no demand for a center, as well as it does not depend on wifi (besides remote accessibility), so it does have a great deal going for it. I've currently highlighted the possibility for this device to be disabled by just eliminating the batteries, although as I also mentioned, it's unlikely that somebody will certainly spend the time to find the alarm and also determine how to open it, with 120dB blasting their eardrums, especially when it's bound to attract a reasonable little interest, so this is an uncommon scenario, to be reasonable. Inevitably, it would be much better if you could pick various other tools to cause the alarm based on the type of setting the alarm remains in, yet this is just how it is with all alarm in HomeKit, in that the alarm can only be triggered by gadgets in its very own community. This is where, in some ways, the Aqara system has the side, as you can appoint different sensing units to work as the trigger in different modes. The Aqara system doesn't presently expose the four settings in HomeKit currently though, and also the United States Aqara center is nearly twice the cost of this Onvis alarm sensing unit, even before you start getting sensors, which can vary in between $10-- $20 each. If you currently have some Aqara sensors as well as the hub, you possibly won't require this, presuming Aqara does bring the four modes into HomeKit. - camera hai nam
