ICI AD l-'ORMl'l-A Mi lHOI) liUt'ocliicliun INTRODUCTION The ICTAD Formula Method for reimbursement of price fluctuation of materials, labour and equipment in construction projects was introduced in January 1993. The Revised Edition which was published in September 1998 introduced the simplified Formula Method for contract values less than Rs. 5 million. With this Second Edition - June 2008, the applicable limit of the Simplified Formula has been increased to Rs. 10 million from the original value of Rs. 5 million. As in the previous edition, this publication will also illustrate in details the method of application of the formula method and example for using the formula. The publication is divided into two sections and Section 1 covers the Formula Method applicable to contracts exceeding Rs. 10 million. Section 2 describes the simplified method of the Formula Method for contracts not exceeding Rs. iO million. Due to the varied size and complexity of large projects, when using the method described in Section 1, the input proportions shall be computed by the Employer and included in the bidding documents. The simplified formula described in Section 2, recommended to be used for small contracts, is based on same concepts as that for major contracts, but the input proportions are built into the formula itself.

It is suggested to exclude the less cost significant items, in computing the input percentages, since the combined effect of such items will be less than 10% of the cost of total inputs. Hence the total contribution of the major inputs will be considered as 90%. The computation of input proportions is based on the costing of major input items required for the proposed construction. The costs will be calculated using the prices that prevailed at the time of bidding. The cost of major inputs will be considered as 90% of the total cost. The total costs of all the inputs will be then derived by dividing the cost of major inputs by 0.9. Input proportion of a particular input will be computed as the ratio between the cost of the input and the cost of ail inputs. A suggested method for computing input percentages is illustrated in ANNEX A. 1.5 INDICES The indices used in the formula shall be those published by the Institute for Construction Training and Development (ICTAD). Monthly indices will be published in Bulletin of Construction Statistics. The type of indices applicable to this Formula shall be Materials (M indices), Labour (L indices) & Plant & Equipment (P indices). When there are more than one index published for same input the appropriate index shall be indicated in the bidding document. For example, four types of indices are being published for cement: One based on ex-factory prices; one based on imported cement; one for open market price; and the fourth for the weighted average.

I( IAl) I OK,Ml I .A .METHOD Annex A ANNEX A A SUGGESTED METHOD FOR COMPUTATION OF INPUT PROPORTIONS A suggested method for computing input proportions for the BOQ given in Sheet No A1 of this Annex is given below. The BOQ consist of 169 work items and two contingency items. The total contract sum is Rs. 11,555,005.55. The value of work item (excluding the contingency items) is Rs. 10,504,550.50. The first step in computing input proportions will be the identification of non-adjustable element. Step I: Identification of Non-adjustable element The following are specified as Non-adjustable element for the reasons explained. Item A! - Providing of a Performance Bond Performance Bond is submitted at commencement of the contract. Item A2 Therefore it is not time dependent. Any cost associated with the Item A3 extension of the performance bond can be dealt with the contractors Item A4 claim for extension. - Providing an advance payment guarantee. This item is also done at the commencement. Therefore its expenditure is not time dependent. - Providing an Insurance Cover Similar to Items A1 & A2 -Construction and maintenance of an office for Engineer Providing the facility is done at commencement. Only the maintenance of it (which is comparatively less) is time related. SIX DM) I J>; i ION. JUNE 2008 17 Institute for Construction Training and Development (ICTAD)

iri'AD iormi i a mi:i non Annex A Step 2: Dis-regarding of items for which the breakdown of inputs cannot be given easily There may be some items in the BOQ, lor which break down of inputs cannot be easily worked out. Lump sum items is a good example for this. Due to the difficulty of estimating the inputs for such items, they are disregarded in computing the input proportions. The contribution from such items to price variation is considered as the weighted average of all the other items. However, unlike the non-adjustable element these items are considered for final computations of fluctuations. The items disregarded for computation of inputs in the example selected are listed below and are struck off from the BOQ in Sheet A1 A8. B9, F3, F4, G1, G2, H21 - H24, H27 - H29 and J1 - J5 The disregarded items in the BOQ contribute to about 3.6% of the value. This percentage should not be a considerable amount. When the items are disregarded the total of the BOQ reduces to Rs. 9,395,465.50. Step 3: Grouping of items When scrutinizing the balance items of the BOQ. it is seen that similar or marginally varied items are listed separately. The inputs for these similar items will be either same or differs marginally. Hence to facilitate the computations, those items are grouped together. In some instances the same item when applying for different components is measured in different units [example : RCC concrete in slab (CA8) and RCG concrete in beams (CA9) measured in m2 and m3 respectively)]. These items were also grouped together by converting the quantities in to a common unit. SECOND KD1 NON. Jl NT. 2008 19 institute for Construction framing and Development (1C I'AD)

(Sheet A2) a. Marginally varied items are grouped together, (c.g. different in location, type of finish) b. No items arc grouped when the mixing proportionate are different, (e.g. 1:2:4 concrete is not grouped with 1:3:6 concrete) c. Generally, inputs of the items grouped, should be similar [exception for that in the example considered is in the case of DPC which needs an additional input (tar) but is grouped under cement plaster due to the fact that only a small quantity of DPC is involved]. d. Items, related to aluminium windows, PVC products and electrical installation are grouped separately without indicating the quantity and the unit. e. Since the input items of 1:2:4 (20 mm) concrete and 1:3:6 (40 mm) concrete differ only from the aggregate size (apart from mixing proportions) and due to the reason that a common index is being published for aggregate (metal) the two items are considered as two sub-groups under the main group No. 3. Two sub-groups are necessary due to the reason that vast variation of input proportions between the items. Similarly cement plaster and lime plaster are also considered as sub-groups under main group 8. SH'OM! 1.1)1 !'IO\\, JI NK 200X 20 Institute for Construction Framing and Development (1C I AD)

Step 4: Identification of cost significant groups The groups are re-arranged on the descending order against the amount and are shown in Sheet A3 (The re-arranging is done purely for explanatory purpose and is not required in actual computations). The 6th column represents the cumulative amount. The 7th and 8lh columns show the percentage of the cumulative amount and percentage of cumulative items respectively. When scrutinize the re-arranged items in Sheet A3 it is seen that; a. about 9% of the items representing more than 28% of the cost. h. about 20% of items representing 57% of the cost. c. 80% of the cost represent by about 40% of the item. d. To represent 90% of the cost about 60% of the items are needed. The formula considered 90% of the inputs directly while the balance 10% of inputs are considered indirectly. I Ience in the example under consideration the following are selected as cost significant groups. (Falling around 90%) a. Brick work b. Asbestos roof with frame c. Cement and lime plaster d.

It should be noted that the total cost of selected inputs (Rs. 7,212,665.31) represent about 85% of the cost of significant items in Sheet A4 (Rs. 8,515,361.00). (This difference is due to the overheads . and profits included in the cost). The contribution from four of the items is below 0.50%. Step 7: Computation of input proportions The less cost significant inputs (say less than 0.50% contribution) are eliminated from final computations and the balance items only are shown in Sheet No. A10. 'fhe total amount of cost significant inputs is computed as Rs. 7,154,670.51. According to the concepts of the formula this should represent only 90% of the cost of inputs. Hence the total cost of inputs is estimated as Rs. 7,949,633.90 by dividing the 90% of cost by 0.9. fhe input percentages of each input is then computed in relation to the total cost of inputs.
