During excavation of the borrow material at the project site, the Contractor encountered
<br />significant subsoil moisture. This required the placement of geogrid material along the haul
<br />road to stabilize the road surface, which significantly improved the productivity of the haul
<br />trucks. This resulted in an added cost to the project of $13,788. In order to prevent long term
<br />erosion problems at the outlet, the Company elected to extend the outlet pipe to provide a better
<br />downstream flow alignment. This resulted in an added cost to the project of $3,200.
<br />Remobilization
<br />The delay in receiving SEO approval and the subsequent loss of five critical working weeks on
<br />the Mesa created a situation that the Company, Contractor, and Engineer did not want to have to
<br />address. Given the high moisture content of the borrow material, it became imperative for the
<br />Contractor to have long warm days to assist in drying the material. The late start date resulted in
<br />shorter days, cooler nights, and less ability for the Contractor to work the material to achieve the
<br />desired moisture content and density. In October 2008, it became obvious to the Company,
<br />Contractor, SEO, and CWCB staff that the project could not be completed, and a winter
<br />shutdown plan was submitted to SEO.
<br />In the fall of 2008, the Company negotiated a new contract with the Contractor to complete the
<br />project. It was based on time and productivity lost due to the delay in plan approval, the need to
<br />do extensive unplanned work on the relining of the reservoir outlet (pursuant to a SEO approved
<br />change order) and the need and commitment of both the Company and Contractor to finish the
<br />project. Given those factors the Company negotiated a new contract to complete the project for
<br />a revised contract price of $850,000 or an increase of $100,000.
