  3. INTRODUCTION Due to major characteristics; large, heavy and expensive products of the construction industry differ in many ways from other industries. As a result, the higher involvement of many types of inputs is essential for the substantial completion of projects. The gradual increase in the price indices expos a rising cost of construction inputs in the domestic industry mainly, due to inflation. There are two broad ways of calculating price fluctuation that compensate the parties to the contract in fluctuation; namely the traditional method and formula method. The traditional method is a full reimbursement method and on the other formula method is a partial reimbursement method However, it is often argued that Sri Lankan contractors are not satisfied with the way price fluctuation is paid with the formula method and the way of calculating methods of input percentages used by Sri Lankan professionals due to the difference of actual price fluctuation and the amount reimbursed from formula method . 2

  4. Task 01: F = Price adjustment for the period V = Valuation of work done during the period concerned (work done + 80% materials at site) {from the interim statement} Vna = Value of non – adjustable element for the period {from the interim statement} Px = Percentage cost contribution of input X {from the tender document/contract document} Ixc = Current index for input X {from ICTAD statistical Bulletin} Ixb = Base index for input X {from ICTAD statistical Bulletin} 3

  5. Task 02: Task 2.1: Non Adjustable Item Reason Preliminaries Fixed Administrative Costs and fixed Site Establishment include in Preliminaries Provisional sum The purpose of provisional sums is to provide a mechanism for dealing with unforeseen circumstances without requiring constant renegotiation of the contract terms. This contributes to contractual stability and reduces the need for frequent adjustments during the construction process. Extra works valued under current market rates. No require to allow price fluctuations because valued under current market rates. No require to allow price fluctuations because valued under current market rates. No effect to contractor pricing Variations valued under current market rates. Client supply materials Task 2.2: Disregarded Item Changes in regulations or permits that affect construction processes. Reason Legislation changes or stricter permit requirements can lead to additional costs, such as the need for specialized equipment, extra inspections, or alterations to meet new standards. These factors are sometimes not adequately considered in the initial cost estimates Not included 90% of the most significant cost elements L2 – Semi Skill Labour P1 - Small Equipment Not included 90% of the most significant cost elements P2 - Heavy Equipment Not included 90% of the most significant cost elements M22 - General Timber Not included 90% of the most significant cost elements M19 - Sanitary Items Not included 90% of the most significant cost elements M27 - Paint Not included 90% of the most significant cost elements M6 - Rubble Not included 90% of the most significant cost elements M14 - Structural Steel Not included 90% of the most significant cost elements M24 - Glass Not included 90% of the most significant cost elements M26 - Electrical Wires Not included 90% of the most significant cost elements M38 - Electrical Fittings Not included 90% of the most significant cost elements 4

  6. Task 2.3: Refer Annexes Task 2.3.1: Refer Annexes Task 2.4: Refer Annexes Task 2.4.1: The decision to consider only 90% of groups as cost significant in the CIDA formula for price fluctuation adjustments may be based on practical considerations and risk management principles. This approach likely aims to strike a balance between addressing the impact of significant cost fluctuations while avoiding undue complexity or overemphasis on minor cost changes. Here are some possible reasons: Focus on Material Cost Impact: The 90% threshold may be applied to groups that have a more substantial impact on the overall cost of a project. For example, certain materials or inputs may contribute significantly to the total cost, and focusing on these groups helps capture the most impactful fluctuations. Risk Mitigation: Considering only the most significant cost groups helps mitigate the impact of minor fluctuations that might occur in less critical areas. This approach allows project managers to concentrate their attention and resources on managing the most impactful risks to the project's overall budget. Practical Implementation: It could be challenging or impractical to track and adjust for every small change in cost across all input groups. Focusing on the most cost-significant groups simplifies the implementation of the CIDA formula and makes it more manageable for practical application in real-world projects. Statistical Significance: The 90% threshold might be chosen based on statistical analysis or historical data, indicating that a relatively small number of input groups are responsible for the majority of cost fluctuations. This statistical significance would support the decision to focus on these groups. 5

  7. The decision to consider only 90% of groups as cost significant in the CIDA formula for price fluctuation likely stems from a combination of practicality, risk management, and a focus on the most impactful factors. It allows for a more efficient and manageable approach to addressing cost fluctuations in the context of project management and contractual agreements. Task 2.5: Refer Annexes Task 2.6: Refer Annexes Task 2.7: Input Percentage (% ) M2 - Cement Imported M8 - Sand 8.9153% 3.5435% 3.4931% 4.4279% 4.2262% 20.1086% 16.6370% 3.9879% 7.8553% 4.0871% 5.1381% 7.5964% 90.00% M7 - Metal M9 - Bricks M32 – Floor tiles L1 – Skill Labour L3 - Un Skill Labour M21 - Formwork Timber M13 - Reinforcement Steel M46 - ZnAl Sheets M36 - Aluminium Doors M20 - PVC Pipes 6

  8. Task 2.7.1: Percentage (% ) Input L2 – Semi Skill Labour 0.6505% 2.0159% 0.3301% 1.7683% 0.6820% 0.9329% 0.0922% 1.8224% 0.4429% 0.0764% 1.1701% P1 - Small Equipment P2 - Heavy Equipment M22 - General Timber M19 - Sanitary Items M27 - Paint M6 - Rubble M14 - Structural Steel M24 - Glass M26 - Electrical Wires M38 - Electrical Fittings Task 2.7.2 The term "total cost of inputs at 100%" in the context of price fluctuation typically refers to the situation where the entire cost of materials, labor, and other inputs that go into the production of a good or service is considered at its full value without any adjustment or reduction. This concept is significant in the context of understanding and managing the impact of price fluctuations on the overall cost structure of a project or production process. Here are a few key points regarding the significance of the total cost of inputs at 100% in the context of price fluctuation 7

  9. Task 3 When there's a significant variance between the actual quantities and the Bill of Quantities (BOQ) in a construction project, it can have several implications. The BOQ serves as the basis for cost estimation and budgeting, so any substantial differences can impact the accuracy of the initial cost projections. Firstly, the input percentages calculated based on the BOQ may no longer accurately reflect the distribution of costs. For example, if the actual quantities are higher than those in the BOQ, it could lead to underestimation of costs if the input percentages are not adjusted accordingly. Conversely, if the actual quantities are lower, it might result in overestimation. Secondly, variations in quantities can affect resource allocation. Contractors may need to reassess their material, labor, and equipment requirements based on the actual quantities encountered during construction. This could lead to adjustments in procurement, scheduling, and manpower planning. Additionally, discrepancies between actual and estimated quantities may trigger contractual issues. Parties involved in the construction project may need to negotiate and agree on how to address the variations. This could involve revisiting the contract terms, considering change orders, or negotiating adjustments to the contract price and timeline. In the standard bidding document second edition in 2007 under the procurement of work major contracts, clause 13.7 states about dealing with price fluctuations as in adjustment of change in cost. Further, it states that the prices computed according to the given formula in the sub-clause with respect to rise and fall in the cost of labour, material, plant and other works and shall be deducted or added for the payment of the contractor. The adjustments of payment certificates concerning the changes in legislation and cost can be determined according to the ICTAD formula. Under a special circumstance, the contractor will have to pay an additional amount and no adjustments on the contract price relevant to the fluctuations can be made. In any circumstances, if the contractor fails to complete the construction work within the given time as specified in clause 17 or 28 and the price adjustments can be made for the performed work using the current indices. 8

  10. CONCLUTION In conclusion, navigating the intricacies of price fluctuations in the construction industry requires a keen understanding of various factors that contribute to these shifts. From volatile material costs to unpredictable market conditions, construction projects are inevitably susceptible to price fluctuations. Embracing advanced calculation methods, such as detailed cost estimations, risk assessments, and contingency planning, becomes paramount in mitigating the impact of these fluctuations. The ability to adapt and respond swiftly to changing economic landscapes is a valuable skill in the construction realm. Construction professionals must not only stay abreast of market trends but also leverage technology and data analytics to make informed decisions. Employing robust pricing strategies and incorporating flexibility into budgeting processes can provide a buffer against unforeseen changes. Ultimately, acknowledging the dynamic nature of price fluctuations in construction is the first step toward proactive management. By fostering a culture of adaptability, integrating sophisticated calculation tools, and embracing innovation, stakeholders can navigate the challenges posed by price volatility and contribute to the sustained success of construction projects. 9
