Background:
The 9th Street Widening, Elgin to El Paso is a 2011 and 2014 Streets General Obligation Bond Project to widen 9th Street to 5 lanes from north of Houston Street to north of Elgin Street. Also included is the construction of new traffic signals at the 9th Street and Dallas Street intersection and new parking lots on the east side of 9th Street south and west of the Patio Condominium Homes, Inc. (PCHI) property. The 9th Street Widening, Elgin to El Paso was advertised for bids on November 2 and 9, 2017. The lowest responsible bidder was Ellsworth Construction, L.L.C., with a Base Bid of $3,240,755.94 and an Additive Alternate 1 bid of $151,289.25 for a total bid of $3,392,045.19.
This Change Order #1 addresses the following additions to the contract:
CO1-1
After the start of construction, it was discovered that the planned Oklahoma Natural Gas underground utility relocations were not on schedule and were conflicting with the contractors work north of Houston St. Due to this conflict, the contract was forced to demobilize on May 26, 2019. Work resumed on August 27, 2019 once the underground and overhead conflicts were resolved and the contractor remobilized onsite. The below costs are the representative costs incurred as associated with the demobilization and re-mobilization of the contractors equipment and labor.
CO1-2
Per contract special provisions SP19, this contract is to be processed with asphalt binder price adjustments per the ODOT special provisions for price adjustment. The below costs summarize the adjustment applied to the asphalt laid to date on the project.
Contract Time Adjustments:

As stated in CO item 1 above as well as within the contractors’ supplemental letter of request, the contract shall be amended to include the additional 45 days of contract time due to conflicts limiting full access to the project.
