the work within the Contract time and show the anticipated beginning times and
completion times for the several major items of work contained in the Contract.
2.

affected exceeds the total float of the project, or where an impact on the contract
completion can be shown.
H.
Acceptance of the Contractor's Schedules by the Engineer shall not be construed as
relieving the Contractor of Contractor's obligation to complete the work within the Contract
time; or granting, rejecting, or in any other way acting upon the Contractor's requests for
108-1
adjustment to the date for completing Contract work, or claims for additional
compensation. Such requests shall be processed in strict compliance with other relevant
