SUMMARY OF PROPOSED CHANGE: The proposal is revised as follows: The unit price for bid item D31 Concrete for Thrust Blocking and Dead-Man Anchors is revised from the original price of $540.00 per Cubic-Yard to $400.00 per Cubic-Yard. The contractor has proposed the use of on-site mixing of high strength bagged concrete for thrust blocks on water main fittings instead of using commercial concrete from a batching plant as required by contract specifications.

All water pipes and fittings for this project are restrained joints, and the concrete blocks are used for added redundancy.
