Task 4 Bid and Construction Phase Services
Sanborn Head understands that the City will prepare and issue bid documents for the
project. However, during the bidding process, a Sanborn Head representative will prepare
for and attend the pre-bid meeting. We understand that the City will prepare the meeting
minutes. Sanborn Head will also assist the City in addressing written questions from the
bidders.
Prior to initiating construction, a Sanborn Head representative will prepare for and attend
the pre-construction meeting. We understand that the City will prepare the meeting
minutes. During construction, Sanborn Head will provide limited observation services (i.e.,
observations limited to installation of critical components) and engineering support
services during construction of the GCCS Expansion in Phase II, Stage II We anticipate our
services to include the following:
« Reviewing Contractor's submittals and answer questions regarding design intent,
materials, and material testing;
= Observing the Contractor's work to evaluate it for conformance with the construction
documents;
= Addressing Contractor's questions; and
a Documenting the progress of the Contractor's work through Daily Field Reports.
Sanborn Head will provide a representative to observe and document the installation of
critical GCCS components for conformance with the drawings and technical specifications
and prepare the required field logs. In addition, Sanborn Head’s representative will
observe pipe pressure testing, HDPE pipe welds, pipe connections into the existing system,
and final weil connections, performed by the Contractor.
It is our understanding that the City will observe and document the installation of the
surface collectors, and the header and lateral pipe trenching. The as-built survey of
completed features will be performed by others and will be provided to Sanborn Head in an
electronic format (i.e., dwg).
For budgeting purposes, we assume that the construction observation will be completed
over seven (14) days, and that our representative will be on-site part time (80 hours total)
during this period. Our observations will be limited to installation of critical components.
Following the completion of the construction, and as required by the NHDES, we will
prepare a report that documents the construction work performed. The report will
address the construction activities observed, test results, and variations in construction
relative to the drawings and specifications, if any. The report also will include record
drawings, photographs, and field test data. The statements presented in the report will be
limited to the extent of our observations and our review of submittals and test results. The
