Design Construction Impacts
After Scarsella Bros. removed the existing shoulder to construct the new climbing lane, a large amount of soft clay was encountered. The clay had to be replaced with firm dry material for a suitable base for the new truck climbling lane. This added work will increase the cost of the construction phase by 4%. Scarsella anticipated completing the project three weeks early, but now will complete the remaining work in the time allowed on the contract.
