What if the project is on one of the larger buildings on base and we can only set up in one area. And to get to the project area we have to take men and materials across existing roof areas. Shouldn’t there be a line item or a way to add costs for projects where protecting existing roof area from construction traffic? This would apply to projects where the area actually being roofed and the set up area are not adjacent to each other.

RESPONSE. All costs to be incurred by the Contractor, to include mobilization, demobilization, overhead, and profit, shall be included in the price proposal. The contractor shall evaluate all risks when proposing.

CLIN 0001BX – 0001DJ has quantities listed for warranties of the various systems, which is standard for the industry, but then on some of the subsequent years some of the line items have N/A listed. I am sure the Government is going to want a warranty provided for work performed under this contract if a new roof is installed. I don’t think it could be forecasted four or five years down the line what the roofing needs might be and what type of systems will be installed so I assume this was an oversight or an error.

RESPONSE. The Government does not anticipate ordering line items which contain

‘N/A’ in the maximum estimate quantity column of a given year.
