2022 TIB Sidewalk – Coveland & 1st Street

The Town of Coupeville is soliciting bids for Sidewalk work related to a TIB grant. The project consists of the construction of new sidewalks within existing Town right-of-way as follows:

  • NW Coveland St – 118 LF sidewalk
  • NW 1st St – 310 LF sidewalk

For more information, please see the Bid Manual linked below.

  1. What is the cross section for the sidewalk? – The sidewalk cross section is included on in Detail 2 on Sheet 6 of the plan set. We are just referencing the Standard WSDOT sidewalk section.
    • Bid item 4 is Grubbing which in sod would usually be about a 4” depth. – This Grubbing item is really intended to cover the stump removal on the west end of the Coveland project. The general sod removal and any additional cut/fill excavation associated with the sidewalk construction should be included in the square yard cost of the sidewalk construction as outlined in Spec Section 8-14.5 of the project manual.
    • Is the sidewalk intended to be placed on native dirt, or on 4” of CSTC as would be more typical?  If so, how is this paid for the excavation and placement of CSTC? – Per the detail, the intent is to construct the sidewalk on compacted native subgrade (or fill where appropriate). Any excavation or fill needed to prepare the subgrade should be included in the square yard cost of the sidewalk construction as outlined in Spec Section 8-14.5 of the project manual.
    • Bid item 6 is roadway excavation with a quantity of 4 CY.  What is this intended to cover?  The quantity seems really small? – The Roadway Excavation item is intended to include the small amount of removal of Pavement (driveway on 1st St, a minor amount of pavement at the west end of Coveland project), Sidewalks, Curbs, and Gutters. It was estimated at 6” depth, and there isn’t very much of it.
    •  At both locations fill is indicated on drawings for the downhill slopes. 
      • Is this fill intended to be bid item 11 for Topsoil Type A?– No, as noted above, all cut/fill required for completion of the work is intended to be covered by the square yard sidewalk cost. This is outlined in Spec Section 8-14.5 of the project manual.
      • Do we have to grub this area of sod as well? Any existing sod should be removed from this area prior to placing fill and topsoil.
