Description
Request to authorize the City Manager, or his designee, to execute a construction change order to Contract 142725 with Otis Elevator Company (New Jersey) to repair the passenger elevators at the Burton Barr Library due to water damage.

Further request authorization for the City Controller to disburse all funds related to this item.
Report
Summary
The project is located at Burton Barr Central Library. Elevator equipment has electronic components that are susceptible to damage when in contact with water, including steel hoist cables, which rust when they become wet, preventing them from operating properly and safely.
This change order includes work on three elevators at Burton Barr Library. Elevator 3 work includes replacing the door operator motor and control box, the panachrome detector, hoist rope and governor rope, gripper pumps and pads, routine brake, and hoistway cleaning and painting. Work on elevators 1 and 2 includes replacement of hoist ropes and governor ropes, gripper pumps and pads, routine brake, and cleaning and painting pit equipment.
Procurement Information
Otis Elevator Company was chosen as the construction contractor for this project using an open and competitive low-bid process according to section 34-201 of the Arizona Revised Statutes.
Contract Term
The term of the additional services is expected to take approximately 41 calendar days to complete. Contract work scope identified and incorporated into the contract prior to the end of the contract may be agreed to by the parties, and work may extend past the termination of the contract. No additional contract work scope changes may be executed after the end of the contract term.
Financial Impact
The initial contract value was established at the bid amount of $664,444. A previous construction change order increased the contract price by $24,007 to $688,451. The current change order exceeds 10 percent of the original construction contract amount, which requires separate Council approval. If approved, this change order will increase the contract value by $73,939.58 for a new contract value of $762,390.58. Funds are available in the Library Department's budget. Contract payments may be made up to contract limits for all rendered contract services, which may extend past the contract termination.
