<br />< , <br /> <br />and additionally retained the services ofthe Sears-Brown Group to manage the overall project. The <br />fee negotiated between the District and the Engineers for these services was $378,718. During <br />construction of the project a number of design modifications were encountered due to utility <br />conflicts and other unforeseen site conditions. The utility conflicts resulted in a significant amount <br />of redesign and meetings to resolve the conflict to the satisfaction of both the District and the oil and <br />gas companies. Additionally, the length of the project in calendar days was extended a number of <br />months to cover the redesigns and utility modifications, requiring additional construction inspection <br />time. <br /> <br />Added Cost: $217,518 <br /> <br />Construction Cham!e Orders: <br /> <br />Change Order No.1 - Upon excavation of the detention pond, the Contractor encountered <br />saturated subsurface soils that required specialized articulated dump trucks and track hoes to <br />excavate the 100,000 cubic yards of "muck" material <br /> <br />Added Cost: $99,618 <br /> <br />Chanf!e Order No.2 - The Oil and Gas Companies requires a minimum halo of 150-feet <br />radius around their wellheads for any material placed near their facility. Stockpiled material from <br />the pond excavation needed to be relocated to meet the Oil and Gas Companies requirement. <br />Approximately 10,000 cubic yards had to be removed. <br /> <br />Added Cost: $5,400 <br /> <br />Change Order No.3 - Upon excavation of the Main Street channel the Contractor <br />uncovered a storm sewer inlet that had not been incorporated into the project design. The channel <br />was modified in the field to accommodate the storm sewer inlet. <br /> <br />Added Cost: $4,250 <br /> <br />Chanf!e Order No. 4 & 5 - During construction of the S.H. 52 channel it was discovered <br />that oil and gas lines ran parallel and crossed the proposed channel in a number of areas. In these <br />areas of conflict the oil and gas lines were determined to have inadequate cover. The proposed <br />channel design was presented to the oil and gas companies by the District prior to construction, but <br />the oil and gas companies elected to take no action with their lines until the time of construction. <br />This conflict prompted extensive negotiations between the District and the oil and gas companies in <br />order to reach an agreement between both parties. These negotiations resulted in the District <br />obtaining significant legal assistance in preparing a new utility easement and having their engineer <br />redesign the channel section. The Contractor was instructed to construct the east-west portion of <br />the redesigned channel, which did not involve relocation of the oil and gas lines. <br /> <br />Added Cost: Channel Construction = $164,170. <br /> <br />Change Order No.6 - This change order dealt with additional items that where not <br />identified on the design plans, such as; tree and sign replacements, construction of an irrigation <br />pond per the request of the Town of Frederick, and minor unforeseen utility conflicts. <br /> <br />Added Cost: $43,256 <br /> <br />3 <br />
