At the pre-construction meeting, it was discussed that stumps and roots from
the clearing and grubbing would remain onsite. Please confirm the location
where the contractor shall stockpile stumps for further use by the Owner.
An area to stockpile stumps and roots will be available in the vicinity of the compost
windrows on the northeastern portion of the site.
Please designate the area where all topsoil shall be stockpiled as described in

on the northeastern portion of the site.
If there is an under-run of topsoil (when comparing the stripped area to the
placement area) can the Contractor utilize the topsoil from the composting area
onsite?
The City utilizes the compost for daily landfill cover and other City projects. It is
therefore not available to supplement topsoil for this project.
At the pre-construction meeting, it was noted that a large stockpile of material

It is located within the proposed slope on the eastern side of the Phase III] footprint.
For this bid, the contractor shall assume that 2,500 CY of Screened Till is available
within this area and the remaining Screened Till required to complete the project
needs to be imported. The attached Schedule of Values was updated accordingly.
Is there any physical testing of the clay material onsite?
There is no physical testing data for the on-site clay material. For this bid, contractors
shall assume it is suitable for use as Screened Till.
At the pre-construction meeting, it was noted that the selected contractor would

volume?
Stockpiled debris and rocks can be moved to a designated area on the northeast
portion of the site. There is no estimated volume for this material. Payment for this
work is covered under Bid Item #4, Grubbing and Topsoil Removal.
