Contract YIPU Addendum No. 1
INTERPRETATIONS AND CLARIFICATIONS:
Pursuant to the Instructions to Bidders, Article 1.B, the following interpretations and clarifications are offered in response to questions from potential bidders and other interested parties. These responses are intended to clarify, not change, the terms, conditions, and scope of the Work.
1. Question: The plans show stream crossings near STA 29+00 and STA 35+00 with approximately 2 feet of cover over the proposed 24-inch FRP interceptor. The referenced protection detail appears to consist of geotextile fabric and does not include concrete encasement.
Answer: Detail 1 on Sheet D7 is installation of gravel jacket (surrounded by filter fabric) which protects the pipe from point loads and impacts. This approach is considered a best practice for pipe protection in stream restoration and leveraged when appropriate (pipe is designed to remain buried). The concrete encasement approach is used at confluence of Cub Run vs Bull Run due to the existing encasement acting as a grade control for Cub Run. A gravel wrap would not be an appropriate pipe protection approach for this situation, and concrete encasement was chosen in its place.
