Question 4. The first paragraph of Part IV: Performance calls for, "The Contractor shall submit to the Parish for approval, five copies of all shop drawings, which shall have been checked and stamped with the approval of Contractor and identified as the parish may require." But there's no other language in the specifications detailing what the shop drawings will be. Will they need to be drawings of the newly installed drainage pipes? Or will the winning bidder have to have stamped improved plans of the area created by an engineer? Please provide clarification of what is expected from the bidder.

Question 5. Will a staging area be provided to store the large drainpipes or any machinery?

Answer 5. No.

Answer 6. Please refer to General Information #3.

Question 7. Would you also add a question regarding if it will be the General Contractor's responsibility to coordinate with the homeowner's when their driveway will be under construction? And will the General Contractor need to provide road plates for continued service?
