Inquiry #3: Section 13-12.03A states; "Construction, use and removal of the TCDS is restricted to the time period between May 01 to October 31, 2020", which seems contrary to Drawing Sheet WPCD-1 Note 2 which states; "Do not construct TCDS before July 1, and return flow to the channel by October 15". Can you please clarify the correct dates for the Temporary Creek Diversion System?

Response #2:
Note 2 on sheet WPCD-1 applies to the options shown on that sheet. These option are based on flow data between July 1 and October 15. See "Seasonal Hydrology for Mill Creek" in the Information Handout for calculated flows for different work windows. However, you are responsible for submitting a TCDS plan under section 13-12.01C(1) of the Special Provisions. Your TCDS plan may vary from what is shown on WPCD-1, but must be authorized by the Engineer. The dates in section 13-12.03A come from work windows in the PLACs.

Inquiry #6: 1) The construction stages provided don't appear to adequately accommodate the construction of the detour, (particularly from "D1"-station 10+00 to 12+00) where only one lane of travel way will be available. Additionally, the 0'-15' cut for the detour is shown to catch at the existing "M1" line immediately adjacent to the one lane of traffic without the protection of railing. Similar staging also appears necessary to refill the detour cut prior to completing the mainline roadway. Can additional staging details and quantities be provided to accommodate the detour construction and removal?
2) Is the embankment to refill the detour cut between "D1"-stations 10+00 and 12+50 included in Bid Item 36- Roadway Excavation (Detour Removal), and if so can an embankment(N) quantity be provided?

Response posted 02/19/2020
Response #2:
1) Please bid per the contract documents.
2) The quantity of material to be excavated during construction for this portion of the detour is shown on the bottom of sheet SCD-1. The project will produce excess material from other bid items, sufficient to backfill the detour to the original contours. Please refer to section 19-2.03B, Surplus Material in the Special Provisions. "Ensure enough material is available to complete the embankments before placing the material at other locations on the job site or disposing of it."
