Plan Sheet / Specification Reference=Bid Opening

We request that the Bid Opening be revised to a later date, preferably a minimum of one week, September 26, 2002 to provide time between bids in Districts 4, 8 & 11.
Because the 905 project is a "Design Sequencing Contract", additional effort and time is required for developing an Estimate. The design portion in conjunction with the normal quantifying and estimating function's increases the work effort by approximately 30%. 
Please assist us by revising and sequencing these Bid openings so that we may assist you with complete and accurate estimates for your projects. 

  • No.

Plan Sheet / Specification Reference=Bid Item #. 82 BAR REINFORCING STEEL (RET. WALL)

  • Agreed the actual quantity is approximately twice the pay quantity but it is FINAL PAY.
