REMARKS BY THE ALDERMEN

Alderman Comeau

| only have one brief one. If you're not doing anything tomorrow afternoon, two o'clock Homan Stadium first round of the
high school baseball playoffs. First time in history North has faced South in the playoffs. South is the three seed | believe
in North is the 14th seed. So go out to Holman and check out those two high schools playing each other in the playoffs
tomorrow. It should be a great game. Last time they played, it was a one nothing game that went nine innings, | believe.
Super exciting game. So check that out if you're not busy tomorrow at 2.

Chairman Clemons

All right, sounds good. Anyone else?

Alderwoman Timmons

Pipe Supports

Scope: Methuen Construction had concerns with the pipe support system called out in the had distri ECN-002 expressing their with the existing roof
integrity. Following this decision, Methuen had GPR on site to scan the rooficeiling to furlher examine existing conditions. It was determined that there were various voids all throughout the ceiling, In
order to further explore the ceiling integrity, we had to perform some exploratory drifting to accurately map out ihe voids in the ceiling. We also performed pull tests on sampte anchors. After gathering all
this data, the owner/engineer was able to provide a pipe supporl design as requested by the city of Nashua, Once we had the design, we called a Hilti rep to inspect the ceiling, and provide Unistrat’'s
and Hilti epoxy. We then furisted and installed the Unistrut gnd pipe support system. Labor i i above, includi ig Staging + delivery, matenat pickups, subcontracto
