Question #4 - We understands that CAD drawings will be required for the design phase of the project. For the inspection report however, to show the locations of identified ACMs would drawings clearly marked by hand suffice, for cost saving purposes?

electronically, Contact information for Allen Corson was provided if the consultant wishes to review
the documents prior to their submission.

ability to negotiate or not allow exceptions. Could you please clarify the agreement terms and if they are
negotiable?
Response: If your firm has specific exceptions to the language contained in the insurance
requirements or RFP provide an attachment to the bid form listing those exceptions. The contract will

specifications, as these are not environmentally regulated?

consultant is required to coordinate with the architect and provide all abatement specifications. The
documents should be fully coordinated and work in harmony with each other.
Question #14 – If PCB materials will be assessed visually this summer (2020), and samples collected for
analysis in 2022, how should this be addressed within the requested bid document to be prepared in
2021?
Response: An approach to PCB testing and remediation will be developed with the building
committee after the visual assessment and potential source material quantities are estimated and the
risk and reward options of testing has been reviewed with the committee. It is anticipated that all
testing and specifications will be finalized prior to bidding based on the selected approach.
Question #15 - There are no unit costs included for paint chip samples (if needed), waste
characterization samples (TCLP) TEM or SPLP samples (for potentially recycling painted concrete or
reusing as clean fill). These may be required depending on the levels of lead found in paints during the
inspection phase. Should we include unit costs for these and if so how many for each should we
assume?
