The drawings show various locations and lengths of culvert pipe to be removed for both 18” and 24” CMP.

See the Bid Schedule and Plan Sheet H.1 for culvert removal required under Pay Item 20301‐1900; there are 12 each under Schedule A, and 17 each under Schedule B.

Since the project requires a platform weighing system, contractor will need a laydown area that will accommodate the scale itself, a scale house and adequate room for trucks to maneuver into and out of the scale area. The construction turn outs shown would not be enough space to accommodate all this and they will be needed for laydown of materials as well as turn arounds during the project. Contractor suggests an area on the right side of the road at about station 15 + 50 utilizing an existing driveway there. This area is at the beginning of the road and is a logical place to locate the scale. It can be graded out and temporary gravel placed to make a good base for the scale and trucks. Contractor would assume full restoration of the site at project completion. Is this acceptable to the government?

There are no provisions within the contract for where a scale must be located. It does not need to be located within the project limits 1/3/2018 x

Paragraph 2, Subsection 416.08 – discusses the application of “lime or cement” as a slurry mixture. It states ‘When lime or cement is required”.
