20210910 Bridge St E Hollis St Nashua Sanborn Head Amend 1.docx 4381.00
s Item 1009.22 - Stockpile and Off-Site Disposal of Unanticipated Contaminated Soil.
Sanborn Head will coordinate with the NHDOT to receive the most recent version of the
Standard Specifications identified above and update them as necessary for the scope of this
project. The information obtained as part of the draft Environmental Screening Report
suggests that groundwater is deep and unlikely to be encountered during construction. As
such, we did not included costs to prepare Special Provisions related to temporary
dewatering or management of contaminated water during construction.
We will work with McFarland Johnson to establish pay items for work described in the
Special Provisions related to environmental soil management. We anticipate that
contingency pay items may be incorporated into the bid documents for different types of
off-site soil disposal facilities and unanticipated environmental conditions.
Task CD2 - Bid Assistance
We included an allowance for 8 hours of bid assistance to McFarland Johnson to respond to
pre-bid questions related to hazardous materials and geotechnical sections of the bid
documents.
Task CD3 - Meeting
We included an allowance for one meeting to be attended by the Sanborn Head Principal-
in-Charge at the offices of McFarland Johnson in Concord, NH during the Construction
Documents and Bid Assistance phase.
