Per 1-04.6,the City evaluated this request and negotiated the adjustments to the bid items below. Lost Overhead Per 1-04.6 of the 2010 WSDOT standard specifications,part 2,section c for variations in estimated quantities,decreased quantities: "an adjustment for the anticipated contribution to unavoidable fixed cost and overhead from the units representing the difference between the adjusted final quantity and 75 percent of the original Plan quantity"is allowed as part of the equitable adjustment negotiation. Per the construction manual, "Finally,the negotiation should include a look at reallocation of undistributed unavoidable fixed overhead costs.The contractor has allocated these to 100 percent of the proposal amount.The bid price is firm as long as 75 percent of the units are measured and paid. If the final adjusted quantity is less than 75 percent,then the anticipated contribution of the units not performed(up to 75 percent)can be identified, negotiated and included in the equitable adjustment."(2014 Construction Manual, page 1-57). The contractor presented the City with evidence that the unavoidable fixed costs and overhead rate for the Rainier Ave project,during the period in question,was 7%. Using this figure,eligible overhead losses were calculated. Production Underruns Per 1-04.6 of the 2010 WSDOT standard specifications,part 2,section b for variation in estimated quantities,decreased quantities: "Changes in production rates or methods of performing Work actually done to the extent that the nature of the Work actually performed differs from the nature of the Work included in the original plan"is allowed as part of the equitable adjustment negotiation. Per the construction manual,the second factor has to do with the nature of the work actually done, when compared with the work shown in the plans.The most common manifestation of this is"You deleted the easiest units and left me with the most difficult,"or"You added units that were much more difficult than those shown in the plan." Compensable, if true."(2014 Construction Manual—page 1-57). The contractor claimed,and the City verified,that bid item A54-cement conc pavement underran. The majority of the underrun was due to the deletion of the concrete roadway panels originally designed to be placed beneath the railroad trestle along the project's alignment. These panels were deleted and replace with in-situ roadway treatment at the direction of the engineer to eliminate the excavation of hazardous material in the area and provide a more flexible traffic movement during construction. The City recognizes that the deleted concrete panel work was the high production work that the contractor used to calculate their bid price. The remaining concrete work consisted of small pours beneath pedestrian islands. Through negotiation,the City and Contractor agreed that an increase of the bid item price for this work from$247.95 to$497.00. Equipment Underruns Per 1-04.6 of the 2010 WSDOT standard specifications,part 2,section a for variations in estimated quantities,decreased quantities: "Any increase or decrease in unit costs of labor,materials or equipment, utilized for Work actually performed, resulting solely from the reduction in quantity"is allowed as part of the equitable adjustment negotiation. The contractor claimed,and the City verified,that bid item A018—sequential arrow sign underran. The majority of this deletion occurred as part of the construction sequencing. The City recognizes that the deletion of the use of the arrow board equipment is an eligible underrun.
