Contract Term
The term of the additional services is expected to take approximately 235 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.

Change Order 1 increased the original contract amount by $24,007 and Change Order 2 increased the contract amount by $73,939.58.
