David A. Simmons, Superintendent
Wastewater Department
Boiler Repairs — Change Order #2
To approve Change Order #2 in the amount of $16,939.29 to the contract with
Armand E. Lemire Company Co., Inc. of Hooksett, NH for the installation of new
boilers at the Wastewater Treatment Facility. | Funding will be through
Department: 169 Wastewater; Fund: Wastewater; Account Classification: 81
Capital Improvements.
The original contract in the amount of $61,080 included labor only for the
installation of the new boilers, demo the remaining boiler and install the
condensate pump. Purchase Order # 123277 was issued. Change Order #1 in the
amount of $8,755.85 was processed when it was determined to be more
advantageous to have Lemire purchase the materials (miscellaneous pipe fittings
and check valves) directly.
Change Order #2 in the amount of $16,939.29 became necessary when the
contractor went to install the three new condensate pumps, they discovered that
the piping to and from the existing condensate pumps were so riddled with holes,
that additional labor was necessary to replace the piping to and from the
condensate pumps. Additionally, the burner controls had to be removed from the
burners and relocated to allow the units to fit within the boiler room itself. This
relocation required that the controls be rewired. This work was authorized at the
time to not stall the project.
Finally, there were two gas pressure regulators bought with the original boilers.
One regulator is rated for 1 psi and the other regulator is rated for 0.5 psi. The gas
pressure at the main at the facility is 2.0 psi. The contractor has quoted $2,520 to
purchase and install the correct size pressure regulators.
Upon approval of Change Order #2 the total contract value will be $86,775.14.
