  1. Construction Planning & Management Construction Project Procurement process and Construction Project Delivery Methods Dr. Attaullah Shah

  2. Definition It is the process required to supply equipment , material , service and other resources needed to carry out a project that satisfy customer Procurement Process

  3. Procurement is acquisition of goods and services. Project Procurement Management includes the contract management and change control processes required to administer contracts or purchase orders issued by authorized project team members. Procurement Management

  4. Procurement means the activities related to purchase, subcontracted items • Procurement items are usually classified as goods, work or services (GWS) • Goods represent raw material or produced items • Work means contracted labor • Service means consultation • Planning, budgeting, scheduling and follow-up control of all fall under procurement management • Logistics plan includes everything related to the transport and storage of materials for the projects. GWS items cannot be scheduled to arrive just-in-time (JIT). Provision must be made to store and protect them until they are needed. Procurement of Items

  5. Procurement management refers to planning and control of the following • Equipment , material or components designed and provided by vendors specifically for the project • It may be a portion of a work package or entire work package • It may be off-the-shelf (OTS) equipment and components • bulk material, like cement, metal piping etc. • Consumables items; nails, bolts, lubricants • Support equipment for construction, cranes, lifts etc • Administrative equipment, computers, project office facilities Procurement Management

  6. Industrial Project Cost Distribution

  7. Project Procurement Management Processes and Key Outputs

  8. Plan Purchases and Acquisitions. Determining what to purchase or acquire and determining when and how. • Purchase of equipment • Procurement of works • Procurement of supplies etc • Plan Contracting – documenting products, services, and results requirements and identifying potential sellers. • Developing the requisite documents • Specification • No and make etc. • Procurement Cycle

  9. Request Seller Responses. • obtaining information, quotations, bids, offers ,or proposals, as appropriate. • Inviting bids • Inviting quotations • Request for Proposals ( RPFs) • Expression of Interest ( EOI) etc. • Select Sellers. • Reviewing offers, choosing among potential sellers, and negotiating a written contract with each seller. • Tender/bids opening • Evaluation and Assessment of bids • Negotiation if required and allowed • Selection of the seller/contractor

  10. Contract Administration – • Managing the contract and relationship between the buyer and seller. • Reviewing and documenting how a seller is performing or has performed to establish required corrective actions • Provide a basis for future relationships with the seller, • Managing contract-related changes and, when appropriate, • Managing the contractual relationship with the outside buyer. • Contract Agreement • Contract Closure – • completing and settling each contract, including the resolution of any open items, • Closing each contract applicable to the project or a project phase.

  11. Procurement planning involves identifying which project needs can be best met by using products or services outside the organization. It includes deciding • whether to procure • how to procure • what to procure • how much to procure • when to procure Procurement Planning

  12. Make-or-Buy Analysis • Make-or-buy analysis: determining whether a particular product or service should be made or performed inside the organization or purchased from someone else. Often involves financial analysis Procurement Planning

  13. Assume you can lease an item you need for a project for $150/day. To purchase the item, the investment cost is $1,000, and the daily cost would be another $50/day. How long will it take for the lease cost to be the same as the purchase cost? If you need the item for 12 days, should you lease it or purchase it? Make-or Buy Example

  14. Set up an equation so the “make” is equal to the “buy” • In this example, use the following equation. Let d be the number of days to use the item. $150d = $1,000 + $50d • Solve for d as follows: • Subtract $50d from the right side of the equation to get $100d = $1,000 • Divide both sides of the equation by $100 d = 10 days • The lease cost is the same as the purchase cost at 10 days • If you need the item for 12 days, it would be more economical to purchase it Make-or Buy Solution

  15. Expert Judgment • Expert purchasing judgment can also be used to develop or modify the criteria that will be used to evaluate offers or proposals made by sellers. • both internal and external, can provide valuable inputs in procurement decisions • Contract Types • Different types of contracts are more or less appropriate for Different types of purchases. • Fixed-price or lump-sum contracts. • Cost-reimbursable contracts.( cost Plus) • Time and Material (T&M) contracts. Procurement Planning

  16. Project Delivery Methods

  17. An owner`s primary goal in choosing a delivery method is to ensure that; • It will meet project objectives, at the same time, • Allow the project to be delivered on time and within budget. In a risk-free, predictable world, -- this is simple task But, world is full of • unpredictable forces, • Undesirable outcomes. • So, owner must monitor the process to prevent unpleasant outcomes along the way. Introduction -1

  18. Construction projects have many unique characteristics. • Creating a large facility takes a long time, • It involves a large capital investment, • Cost overruns, delays and other problems, • Process of building is complicated, why? • Component numbers by many suppliers • Even if an owner builds repeatedly, the nature of product and parties involved in building depends on • Time, Site conditions • User needs, Economic health Introduction-2

  19. When compared with other industry professionals, Designers and constructors have less opportunity to transfer lessons learned from project to project. All of these factors combine to create uniqueness, which carries with it heightened risk. A building not delivered on time usually costs more than planned, and late delivery can have cascading effects throughout an owner`s organization. Example: need a facility for chip manufacturer. Introduction-3

  20. Owner`s pitfalls: Late delivery of facility, Miss the market, A competitor enter to market. How avoid these pitfalls? Set up a team of people; whose skill match the type of project Who have a proven record of delivering such projects. Before team set up, owner decide how members will interact, with owner organization, and each other. This approach is called project delivery method. Introduction-4

  21. Lessons from History;Owner choose a delivery method after studying history. Why projects failed? Separated functions .. Communication of designer and constructor. In a design change contractor may wait,. Scope creep .. Scope may be product quantity and character of work, If scope of work increases, the cost also increase. Factors of scope growth. Complexity, politic, critical user left out, miscommunication between users. Project acceleration .. Buyer prefer quick delivery Poor working relationships .. Less time, personal wok style, contract forms Managing project risks-1

  22. Two primary professionals` (designer and constructor) communication is key to project success. Projects tend to be; Large, Complex, Unique Actions of one can have a major impact on the concerns of the other. Example: A design change after construction has started can adversely affect construction sequencing. So increasing cost due to lost efficiency. Separated Functions

  23. Scope of work on a project : It can be defined as product of; the quantity of the work, and the character of work. Example: 1000 square meter rock excavation defines excavating subcontractor. Scope of work is primary determinant of costs on a project. If scope increases costs also increase. Factors on scope increase: Involving complex and highly political organisations, Tight timelines Leaving out of a critical user Miscommunication. Scope Creep

  24. Buyer prefer quick delivery. Benefits; Lowers some costs, Put it into service sooner, Cut interest costs Psychological impact Enthusiasm exist Risks of going too fast; a) No consideration of all elements of design Incomplete documents b) Construction may be stopped, Project acceleration

  25. Unique character of construction.. there is not enough time to work out all the relationships necessary to perform difficult interconnected work. Personal work styles Contract forms can work against teamwork Communication among project participants formally We can mitigate these pitfalls through organization of team, contract choice, partnering sessions, and delivery methods. Poor working relationships

  26. Selecting a delivery method and a contract type involves sequential decision making. General risks Project specific risks Owner organization risk Assessing Project risks

  27. General risks occur on a project can be classified into four major areas. Financial .. Project may cost more Time .. Project may not complete within planned time Design .. Project may not perform the function Quality .. Project may have poor quality materials or workmanship General risks (1)

  28. A project team will address these risks during project development. Risks are approached differently in preconstruction and construction phase. Preconstruction: it is known as design phase (working out functional, aesthetic, material requirements of the job) In this phase project team balance DESIGN/COST equation. Risks occurs when realistic assessments of costs are not part of design process. Construction: emphasis shifts from DESIGN/COST tradeoffs to executing a project within the constraints defined by contract documents, schedule, and budget. Risks involve time and external unknowns. Some are community disapproval, labor actions, weather, site, etc. General risks (2)

  29. In addition to general industry risks, there are specific risks that all owners and designers must take into account during their work. Site risks .. Neighbours, regulatory environment, geological characteristics, underground conditions, economic region. Project itself .. Uniqueness, complexity, new technology. Project-specific risks

  30. In addition to technical concerns, there are organizational and financial risks. Knowledge of building process, Financial changes Tightening the schedule Owner organization

  31. Once general and specific project risks assessed, owner must build a good project team to minimize the risks. • Choosing the right delivery method: Before choosing project team members, owner must choose delivery method. Dilemma here: one of price versus performance • Choosing a contract type: goal is to purchase actual construction service for lowest price possible without creating undue risk for owner. • Monitoring the entire process: owner must devise mechanisms to ensure that budget is monitored, schedule maintained and quality ensured. Minimizing risk

  32. The term delivery method refers to the owner`s approach to organizing the project team. Design/Bid/Build (D/B/B) TraditionalMethod Design/buildmethod Construction management method Combination of these strategies may be employed as well. Delivery methods

  33. Design/Bid/Build (D/B/B) is often considered the traditional project delivery method. • All design work is completed • Bid process completed • Construction Starts. When this delivery method is selected? • When cost is primary important • Schedule is secondary important, and • scope is well defined. three-party arrangement: owner, designer, and contractor. Traditional method

  34. The Traditional Project Delivery System

  35. The owner signs one contract with the designer for design services and signs an other contract with the contractor for construction services. Both the designer and contractor work for the owner. The contractor does not work for the designer; however the owner usually designates the designer as their representative during construction. The designer is usually paid based on a prearranged fee or on a percentage of the construction contract. Traditional method

  36. Payment: The contractor is paid based on a lump-sum amount. Designer is paid based on pre-arranged fee, or on a percentage of construction contract. In D/B/B -- the responsibility, risk, and involvement of all parties are well defined. The owner has relatively high level of involvement and control during design, but low involvement during construction. Biggest disadvantage--: the extended time that may be required for completion the design and bidding the project before starting actual construction. Changes after award can be costly to owner. Traditional method

  37. Disadvantages: Biggest disadvantage--: the extended time that may be required for completion the design and bidding the project before starting actual construction. Changes after award can be costly to owner. Traditional method

  38. D/B project delivery method is often chosen to compress the time to complete the project. The completion time usually is reduced because construction can start before all the design is completed. The owner has considerable control and level of involvement throughout the project. This provides flexibility to the owner for revision of the design during construction. When Selected? when the schedule is preliminary, the cost is secondary, and the scope is not well defined. Two-party arrangement: owner and D/B company. Design/build method

  39. Design/Build Method 1

  40. Design/Build Method 2

  41. Design/Build Method 3

  42. Design/Build Method 4

  43. A contract is signed between the owner and D/B firm to perform both design and construction services. All design, including construction drawings, are done y the D/B contractor. All construction is done by the D/B contractor, although the D/B contractor may hire one or many subcontractor. Design/build method

  44. This arrangement can reduce the conflicts between the designer and contractor that often occur in the D/B/B delivery method. How D/B firm is selected? • By a qualifications-based selection (QBS) procedure. • By price Owner solicits proposals from a pre-qualified, safety record, schedule, cost performance on past jobs, and other factors from each prospective D/B firm. Thus, selection is based on qualification rather than price. Design/build method

  45. The cost of the D/B services is usually based on some type of cost-reimbursable arrangement, either cost plus a fixed amount or cost plus a percentage. By price: For project that have a reasonably defined scope, the D/B firm is sometimes selected based on price. For incentives--: The contract may be based on a guarantied maximum amount. Handling inspection is an issue that must be addressed early in the project, because the designer is also the builder. Design/build method

  46. If qualified individuals are available in the owner’s organization, the owner may perform inspection. In some situations, an independent third party is used for inspection services. Design/build method

  47. CM Delivery System

  48. There are many variations of the construction management method of project delivery. 1. Agency CM (pure CM): CM is a firm outside the owner’s organization that acts as the agent for the owner. The agency CM firm performs no design or construction but assists the owner in selecting one or more design firms and one or more construction contractors to built the project. The agency CM firm assumes no risks because are contracts are signed between the owner and the designers and/or contractors. Generally agency CM work for a fee. Construction management method

  49. Corporate CM: is similar to agency CM, except the CM services are provided by the personnel inside the owner's organization. Design and construction is performed by third party organisations. CM manages and coordinates the overall effort. Construction management method
