C20 includes the installation and compaction (not material costs) of the embedment and 12” top rock, as it will be different compaction requirements than the rest of the infiltration backfill. 7) Bid item C8 has a bid qty of 80 LF. I’m coming up with 395 LF. Please confirm. The manifold pipes are not included in bid item C8. The manifold pipes are included in the lump sum bid item C20 for the stormwater infiltration facility.

Special provision section 1-09.14(2)C27 only lists it is to be a 40’ decorative pole per standard plan 117.1 and section 8-20.1 just refers to Renton standards 117.1, 117.1A, 119 & 120. The required luminaire arm lengths & fixture information aren’t noted and don’t appear to be included in the project plans. The light pole shall meet the specifications per COR Std Plan 117.1, which is provided in the Standard Details section of the bid package. The luminaire arm length will be provided in Addendum No 2 (to be posted shortly to City website and BXWA).

Yes. 15) A request has been made to change the gradation for AASHTO 3 and 4 rock. The spec asks for 0% passing the #100 screen which may be challenging to acquire. It has been expressed that there is a concern fugitive dust could impact gradation testing. The current provided gradation for the AASHTO 3 and 4 rock per Special Provision Section 9-03.16 Infiltration Gravel is the City’s requirement for this project to ensure the facility functions as designed. If the material is handled, stored, and placed appropriately per the special provisions then minor fugitive dust accumulation will not be an issue for the project. However, I want to emphasize that the material must be handled, stored, and placed correctly. 16) Will the City provide the names of suppliers that would source the infiltration gravel or select borrow, and how much volume they have available? The City is aware of a least one local supplier with sufficient volume of the specified materials, but we cannot disclose their identity due to public works laws. 17) Is Builders Risk insurance required for this project? No. 18) Special provisions for the select borrow have the No. 40 called out as a 25 min. The WSDOT spec has the No. 40 as 50 max. Was the special provisions select borrow supposed to be 25 max instead of 25 min? The table outlined in Special Provision Section 9-03.14(2) “Select Borrow” is accurate as shown.
