2019 Landfill Gas Collection and Control System Expansion

To approve a contract with SCS Field Services of Reston, VA to construct an
expansion of the landfill gas collection system in the Phase J/II landfill in the
amount of $427,654. Funding will be through Department 168 Solid Waste;
Fund: Bond; Activity: Landfill Gas Expansion FY19.

Bid Tabulation

The City issued an Invitation to Bid for construction of an expansion and
modification to the landfill gas collection system in the Phase I/II landfill.
Periodic expansions of the gas collection system are required as the landfill
continues to be filled with waste. The Solid Waste Department’s engineering
firm, Sanborn Head and Associates, Inc. (SHA) prepared a construction design to
install nine (9) new horizontal gas collection wells, four (4) vertical landfill gas
collection wells with liquid pumping systems, Draintube surface collection on
selected areas of the landfill, and extend the main vacuum header. This expansion
of the gas collection system is required to control odors, mitigate fugitive methane
surface emissions and comply with the NHDES approved Operating Plan — Phase
II Secure Landfill Expansion and the Landfill Gas Collection System Enhanced
Monitoring Protocol/Standard Operating Procedures (EMP/SOP).

The City received bids from four (4) qualified vendors. Based on the low bid and
qualifications of SCS Field Services it is the recommendation of the
Superintendent of Solid Waste to accept SCS Field Services as the vendor to
perform the work listed above.

2018 CIPP Lining
Construction

To approve the construction contract for the 2018 CIPP Lining to Layne Inliner of
Fairfield, ME in the amount of $715,657.50. Funding will be through: Department: 169
Wastewater; Fund: Bond; Activity: Sewer Rehab.

The annual sewer program addresses failing, aged sewers and associated structures and
piping. This 2018 Cured in Place Pipe (CIPP) Lining project is expected to line
approximately 6,200 feet of sewer mains, of which about 5,700 are under roadway and
530 feet are off road. In general, the connecting drainage basins and drainage pipes will
be excavated and replaced under a separate contract. The locations of CIPP Lining
included in this contract are:

Kinsley St - Walnut St to Vine St and from Ritter St to Woodward St
Lake St from Pine St to 254 Lake St (near Caldwell Rd)

Gillis St from 4 Gillis St to Arlington Ave

Manchester St from 17 Manchester St to Hopkins St

Liberty Utilities yard area at 38 Bridge St

Five contractors attended the mandatory pre-bid meeting on March 28. Two bids were
received on April 17 as follows:

Insituform Technologies of Chesterfield, MO $748,705.00
Layne Inliner of Fairfield, ME $715,657.50

The low bid was reviewed and found to be acceptable. Although Layne Inliner has not
previously worked for the City, we have checked their references and found them to be
acceptable.

General coordination issues may impact the construction schedule. For example,
certain parts of the 2018 Sewer Replacement contract need to be done ahead of this
contract. Therefore, this contract may run into a second construction season.
