KITSAP COUNTY DEPARTMENT OF PUBLIC WORKS COUNTY ROAD PROJECT NO. 3668

BAY SHORE DRIVE AND WASHINGTON AVE NW

ROADWAY AND UTILITY IMPROVEMENT PROJECT

Questions & Answers – April 7, 2020

The County has received Questions from prospective bidders and below are the County’s responding answers:

Received via E-mail – from March 13 through April 6, 2020

Question: Are the anchor bolts for the pedestrian and street lighting poles to be stainless steel or galvanized per WSDOT standards?

Answer: Galvanized per WSDOT standards

Question: The trenchless installation procedures listed for this project are by a slurry face Micro Tunnel Boring Machine, however would other methods of installation be considered?

Answer: As verbally provided at the Pre-Bid meeting, the County will consider a VECP as provided for in the WSDOT/APWA Std Specifications.

Question: Would pilot tube be a considered method of installation for the

trenchless portion of this work? Answer: We are open to pilot tube technology as long as the installation method

can achieve the tolerances shown in the special provisions and the Contractor has a history completing projects with similar tolerances.

Question: In the dewatering specifications 2-13.2(3) section D & F. It discusses

both approved drilling methods and that soil sampling is required for pumped wells, recharge wells and on every 5th well point. As the approved drilling methods in section D are not typically used to do the soil sampling in section F. Can a hollow stem auger be used to drill the hole and soil sample. Then high pressure jetted water be used to flush the hole after extraction of the auger to remove any fines. Thus flushing the hole to create a quality water well?

KITSAP COUNTY Page 2 of 3 BAY SHORE AND WASHINGTON AVE NW Questions & Answers

Answer: The drilling methods and sampling requirements provided in the contract documents are correct and shall be used. The request to use flight augers and perform post-drilling jetting of the hole in lieu of the specified drilling methods is not approved.

Question: Does this project have a UDBE requirement? Answer: No Question: On drawing DS03 sheet 33 the details for the different wells show a

concrete layer on the top. Typically temporary wells would not have a concrete seal at the top as they will be removed. Is this an oversite and no concrete is required?

Answer: Although the wells are temporary, they require concrete around the monument/locking cap over the wells. The wells need to be sufficiently robust to withstand the traffic and work going on around them and to be protected from damage throughout the course of the work.

Question: Is a sonic drill rig allowed to install the pumped wells and recharge

wells? Answer: Sonic drilling would be acceptable for drilling the dewatering wells and

recharge wells. For sonic drilling of the wells, the requirements remain to prevent bottom heave and to maintain water head greater than the piezometric head present in the aquifers inside the cased holes during drilling, soil removal from the drilled holes, and well construction.

Question: The Storm assembly on drawing D02, sheet 17 shows a gasket. The

storm assemblies have (2) 1” pick holes and do not have a gasket. Please let us know if a gasket will be required.

Answer: Gasket is only required on assemblies provided for sanitary sewers. No gasket is required for storm assemblies.

Question: Will the castings for this job require WSDOT inspection and

stamping? Answer: We typically require WSDOT inspection and stamping, regardless of

funding source, however, with COVID-19 pandemic and WSDOTs limited availability for fabric inspections, we will make other arrangements if necessary. We do expect to have castings inspected and preferably stamped.

KITSAP COUNTY Page 3 of 3 BAY SHORE AND WASHINGTON AVE NW Questions & Answers

Question: The project calls for a 30” SEWER Kitsap Logo cover, which not commonly produced?

Answer: Kitsap logo on 30" lids for Schedule B, sanitary sewer, will not be required but must be marked "SEWER". Additionally, open pick holes in 30" lids must be provided with rubber plugs.

Question: 26” Kitsap logo cover comes in a 4” frame that has been used in the

county for years. – This project is calling for 6” frames that would require a new assembly.

Answer: No 6" frames for 26" and 30" lids are required, only 4" frames. See Detail 22/DS01. The sewer Easement Clean-out detail (detail PD-13/DS01) calls for the top of the lid to be 6" above finish grade in non-paved/graveled areas, which could possibly be interpreted as a 6" frame. The frame and lid shall be as required in Detail 22/DS01, thus a 4" frame.

Question: In the “Roadway Notes”, Note 5, on sheets C01-C10, calls for vaned

grates per WSDOT B-30.30 (20x24 assembly). Kitsap County typically doesn’t use a 20x24 assembly, only the 18x24 assembly.

Answer: Kitsap County will not require that a 20x24 assembly have Kitsap County lettering. It is the County’s intent to use 18x24 assembly in lieu of 20x24 assembly.
