Change Order #088
Amb. Job #557-5175
Dear Mr. Weems;
We are pleased to submit herewith our change order #088 to perform the following work at
the above referenced premises for the sum of ONE HUNDRED TWENTY THOUSAND
NINE HUNDRED FIFTY SEVEN DOLLARS ($120,957.00);
We have carefully surveyed the new fuel oil piping route as per the following;
• The eight inch conduit which will carry the 1 1/4" supply, return and overflow pipe, will
run through the second floor machine room corridor into the building communications
room and above the lobby ceiling to the fuel oil tank room.
• In order for this work to be done, building ductwork must be removed and re-routed.
Also other electrical piping will have to be relocated. The double door for the
communications room will be removed and replaced by a single door.
• The ceiling lobby sheetrock ceiling will be removed and replaced after the piping is
installed.
• The lobby area in front of the handicap elevators will have scaffolding so the different
trades can work while we keep the elevators operational.
• All work is to be performed on normal working hours, except for the scaffolding work.
There is no overtime included in the other costs.
