Chan�e Order 6 Notes
Change Order No. 6 provides for the following:
• CMR-37 GLS Support Modifications — Elevations for glycol pipe and supports were in conflict
with an existing door and light fixture at the gas compressor building. The contractor notified
the City of the conflict after the supports were installed and proposed adjusting the supports for
$7,090.00. The contractor did not charge for relocating the light fixture. The City agreed to pay
the contractor $2,257.00 after the contractor removed equipment charges, overhead and profit
charges, and half of the remaining cost.
• CMR 38 Digester 1 and 2 Side Access Manways —There are no side access manways on Digesters
1 and 2 which limit interior access. With the addition of the new pumped mixing systems, it
would be beneficial to facilitate access for future maintenance of the pipe and spray nozzles.
The addition of 48-inch side manways will improve access and save cost on crane rentals
equipment during future maintenance activities. Two to three days crane rental will pay for the
cost of a manway.
• CMR 39 Digester Control Building No. 1 Deck. The original contract included replacing the built-
up roof system of Digester Control Building No. 1. During preparation for the worl<, the
contractor noticed rotted gypsum board in areas of the existing bulb T deck and signs of water
leaks inside the control building. Replacement of the deck is necessary. This change order will
provide for demolition and disposal of the existing roof deck, coating the tops of the existing
support beams, installation of a new galvanized deck, and protection of the existing electrical
gear during the demolition and installation work. The contractor initially proposed $41,965.00
for the work but agreed to a reduction in demolition and equipment costs for a final proposed
price of $37,623. The proposed price is fair and reasonable considering that demolition, roof
deck installation, and protection will take place in sections to minimize exposure of the electrical
gear to the elements.
• Item A1-9 Concrete Injections —The original contract included 36 LF of concrete crack injections
for Digesters 7 and 8. Digesters 7 and 8 required extensive cracl< injection in the interior
construction joints, totaling 362 LF. This change order provides for an additional 326 LF of
concrete injection.
• 48 additional calendar days.
Approved CMR's are saved in E-builder.
