Before starting the work and from time to time during its progress, as the Engineer may request, the Contractor shall outline to the Engineer the methods he plans to use in doing the work and the various steps he intends to take. Within 15 days after delivery of the Notice to Proceed, the Contractor shall prepare for submission to the Engineer (a) a schedule fixing the dates at which additional drawings, if any, will be required, and (b) a schedule fixing the respective dates for the start and completion of various parts of the work, each such schedule to be subject to review and change from time to time during the progress of the work. b) Alterations. The Engineer may make alterations in the line, grade, plan, form, dimensions or materials of the work or any part thereof, either before or after the commencement of construction. If such alterations increase or decrease the quantity of work they shall be made at the unit prices stipulated for such work, compensation for increased work shall be made under the item for Extra Work, and for decreased work the Contractor shall allow the Owner a reasonable credit as determined by the Engineer. If such alterations diminish the quantity of work to be done, they shall not warrant any claim for damages or for anticipated profits on the work that is dispensed with. c) Extra Work. The Contractor shall do any work incidental to the proper completion of the contract not herein otherwise provided for when and as ordered in writing by the Engineer, either (a) at the price agreed upon before the work is commenced, and named in the order for the work, or (b) if the Engineer so elects, for the reasonable cost of said work, as determined by the Engineer, plus 15 percent of such cost. No extra cost will be paid for unless specifically ordered as such by the Engineer in writing. The Contractor shall, when requested by the Engineer so to do, furnish itemized statements of the cost of the work ordered and give the Engineer access to the accounts, bills, and vouchers relating thereto. The Engineer shall include in the cost of extra work under (b) above, the reasonable cost to the Contractor of all materials used, of all machinery and of all equipment used upon the extra work for the period of such use. The fair rental for all machinery and equipment shall be based upon the most recent edition of "Compilation of Rental Rates for Construction Equipment," as published by the Associated Equipment Distributors, or similar publication approved by the Engineer. Rental for machinery which was upon the work immediately before, or which shall be required by or used upon the work after the extra work is done, shall be based upon an appropriate fraction of the approved monthly rate schedule. If said work requires the use of machinery not upon the work or to be used upon the work, then the cost of transportation, not exceeding a distance of 100 miles, of such machinery to and from the work shall be added to the fair rental as accepted by the Engineer in writing prior to the rental of the machine. If any machine or piece of equipment becomes unusable due to breakdown or any other cause, the Owner shall not be required to pay any rental beyond a 24-hour period of loss of use and shall not be responsible for any repair costs. The Engineer shall include in the cost of extra work, the cost to the Contractor of additional premiums paid on the required insurance on account of such extra work, and the cost of Social Security or other direct assessment upon the Contractor's payroll by Federal or other properly authorized public agencies. The Engineer shall not include in the cost of extra work any cost or rental of small tools, buildings, or any portion of the time of the Contractor, or his superintendent, or any allowance for use of capital or the premium on the bond as assessed upon the amount of extra work, these items being considered as being covered by the 15 percent added to the reasonable cost. In the event that the extra work involves work or furnishing of materials by a subcontractor or supplier, the Contractor's itemized statement of cost shall include details of the subcontractor's or supplier's cost of the extra work. The subcontractor may add no more than 15 percent for overhead and profit and other items. In the event that the change results in a credit, the subcontractor or supplier shall add 10 percent to the itemized cost of the change. The Prime Contractor may add to the total cost, including the subcontractor's cost and mark-up, no more than 5 percent for overhead and profit where the extra work and materials are furnished by the subcontractor or supplier. Under a credit for omission of work or materials by a subcontractor or supplier, the Prime Contractor shall add 5 percent to the credit amount as shown in the itemized statement of cost. In situations where both a subcontractor and the Prime Contractor furnish work and materials for a change, the Prime Contractor may add on a pro-rated basis the percentages for profit, overhead and bond as specified above. For changed work to be furnished by a supplier or vendor, the Contractor shall furnish the Engineer, on demand, a lump sum estimate or quotation of the cost of the item or items to the Contractor, signed by the supplier or vendor. In preparing detailed estimates for proposed change orders which involve both added and omitted work, the Contractor shall separately estimate the cost of the added work on the basis specified above, and separately estimate the cost of the omitted work on the basis specified above, and the net difference between the two shall be his proposed price for the changed work involved. In the event that an agreement cannot be reached between the Contractor and the Engineer as to the cost of any proposed change in the work, the Engineer may then order the Contractor to proceed with the change on a cost plus basis. d) Contractor's Office and Telephones.
