Maximum Amount Payable $214,500.00 ATTACHMENT C Weston Solutions, Inc. — Change Order Request City of Waterloo/Iowa Department of Transportation Iowa DOT Project HDP-8155(698)--71-07 Assumptions and Clarifications for the Budget Estimate • Performance or other bonds are not required; • The estimate assumes that field oversight activities are required for five consecutive weeks at 50 hours per week (Monday through Friday). This will extend Weston's scope of services through November of 2007. Construction oversight costs are subject to change based on weather, contractor schedule and other field conditions. • Construction oversight costs include travel time and expenses for WESTON personnel to mobilize/demobilize between the work site and our office in Vernon Hills, Illinois. The estimate assumes that one WESTON employee will demobilize from and remobilize back to the work site on a bi-weekly basis(i.e. every other weekend). • It is assumed that Modified Level D personal protection equipment is adequate for conducting field oversight activities (Refer to SSHASP). Higher levels of personal protection will trigger additional costs.
