Background:

Primarily a pavement rehabilitation project with sidewalk and curb improvements on 1st Street from Dallas to College, striping was also included from Main Street & Ft. Worth to 1st Street then along 1st Street to Midway Avenue. Sidewalk work along Ft. Worth as well as 1st Street from Ft. Worth to north of El Paso was included as additive alternates. Bid documents were advertised on February 18 and 25, 2019 and opened on April 2, 2019. The low bidder, for the Base Bid and both Additive Alternates, was Grade Line Construction, LLC with a total bid of $433,615.86.
This Change Order #2 addresses the following additions to the contract:
- At the direction of COBA engineering and construction staff, additional areas of repair have been identified for repairs above and beyond the original quantity within the contract, but still within the scope of the project work within the Old Town Streets - 1st Street from Dallas to College project. These items include additional mill and overlay profile changes in the asphalt street sections, additional concrete pavement patches, subgrade modifications, additional storm inlets & storm pipe, and additional sidewalk and ramps. The line item quantities noted within this change order shall be extended such to contractually cover the associated additional work. A final reconcile change order shall be processed upon completion of the project to finalize the actual installed quantities.
- As directed by The City of Broken Arrow, the contractor demobilized all personnel, equipment, and materials off site for the week of August 23rd. This demobilization and subsequent remobilization of associated work parties was a result of the Downtown Main Street boxing event. The associated costs with this demobilization and remobilization are summarized within this change order.
