1 MHD BRIDGE SECTION WEIGHTED AVERAGE UNIT PRICES GUIDELINES FOR THE USE OF THE WEIGHTED AVERAGE UNIT PRICE TABULATION SHEETS GENERAL 10/16/2008 The listed average unit prices are based on the available lowest 2006, 2007, and 2008 bids for each MassHighway project. Please note that data is not available for every item because many items were not used during this timeframe. Please check the Weighted Average Bid Application, available via the MassHighway website, for the latest unit price data. In cases where unit price data is not available, it is recommended that a unit price be estimated using the available data for the next closest size member. It is important to recognize the necessity of varying the Office Estimate unit prices based on the quantity of the item in question. Since the MassHighway Capital Expenditure Program Office (CEPO) determines funding requirements for projects based on the Office Estimates, it is vital that the office estimate be as accurate as possible and in line with the actual contractor bids. Therefore, the goal shall be to use unit prices that will place the office estimate into the middle third of the bid "pack". This is generally accomplished by adjusting the weighted average unit prices based on the quantity of a particular item. Generally speaking, the larger the quantity of an item the cheaper it will be on a per unit basis. However, there is no hard and fast rule on how to apply this. The adjustment of unit prices is based on experience and judgement. It is better to over estimate (marginally) the unit price of an item than to under estimate it. Some assistance in estimating unit prices for structural items may be found in the representive graphs of the unit costs of main members, reinforcing steel, concrete items, prestressed concrete beams and structural steel. Of note is the number of projects listed for each item. The larger the number of projects the more reflective the average prices will be of the cost of the work. Also, unit price data that indicates an apparent reduction of a unit price over time is more likely an indicator of less complicated work or economies of scale. DEMOLITION OF SUPERSTRUCTURE Demolition of Superstructure is to be listed in the Office Estimate on a Lump Sum basis. Estimate the cost based on the total deck area in square yards of existing superstructure intended to be demolished. (reference charts for Estimating Cost). BRIDGE STRUCTURE LUMP SUM ITEM In general, the Bridge Structure Lump Sum Item is used to pay the Contractor a fixed price for the work done and no measurement of final pay quantity is required. However, the Bridge Structure Lump Sum Item can only be used for those elements of the structure for which the scope of work, the methods of construction, and the type and quantity of materials to be furnished are accurately defined on the plans and/or in the special provisions. All other items must utilize a Unit Price basis of payment since the Contractor's bid is based on estimated quantities that may vary considerably from the actual quantities required during construction. The breakdown of the Bridge Structure Lump Sum Item shall be provided in the Special Provisions and shall specify for each component part the sub-item number, the sub-item name, the quantity of each sub-item, and the unit of each sub-item quantity. The sub-item numbering, naming, and quantity unit convention shall match that used in the latest Standard Nomenclature as specified herein. Please refer to the sample provided on the next page.

2 GUIDELINES FOR THE USE OF THE WEIGHTED AVERAGE UNIT PRICE TABULATION SHEETS 10/16/2008 SCHEDULE OF BASIS FOR PARTIAL PAYMENT Within ten (10) days after the award of the Contract, the Contractor shall submit, in duplicate, for the approval of the Engineer, a schedule of unit prices for the major components of the bridge structure as listed below. The bridge structure Lump Sum breakdown quantities provided below are estimated and not guaranteed. The total of all partial payments to the Contractor shall equal the Lump Sum contract price regardless of the accuracy of the quantities furnished by the Engineer for the individual bridge components. The cost of labor and materials for any Item not listed but required to complete the work shall be considered incidental to Item and no further compensation will be allowed.
