The additional pipe was paid for at the contract unit price. bypassing work was tracked by BR W and the contractOT and paid for on a time and materials basis. The cost of this work is approximately $14,000.00. ---4) WeISli-COiisfructiojfCiimpllfliu~elatedWork~...-- The contractor incurred costs to perform additional work as a direct result of activities on the Welsh development. Welsh requcsted the city to replace an 8" watermain service to 12" diameter after the planned S" service had been installed. Welsh agreed to reimburse the City for the work. The conlractor incurred labor and equipment costs for resetting a hydrant which was hit by Welsh construction traffic. The contmctor incurred additional labor and cquipment costs for constructing watennain in an easement area that Welsh Constnlction had placed an additional6-S feet of fill. The city requested Welsh to remove the material but they have not done this to date. The cost of these work items are $6,356.53. 5) Soil Correction Related Work: Change Order #2 included additional funding for the importing of 5,000 Cubic Yards e offill to replace unsuitable soils encountered during the excavation of the sanitary sewer trench. Change Order #2 also included funds for the removal and pulverizing of old foundation materials encountered on the site. As the wolk progressed, additional areas ofunsmtable materials were encountered in the pond site, Illlder Round Lake Road near 13th Street and under Gateway Court. The increase in unsuitable materials encountered within the project limits required that a large portion be trucked off site as no space was available adjacent to the roadway embankment to ''waste'' the excess materials as was done for the unsuitable materials encountered earlier in the project. The contractor was able to arrange for the removal of several hundred cubic yards of excess topsoil materials from the site at no charge to the City. The City Engineer and Contractor negotiated hauling and import prices for the work. The Contractor was directed to haul 9,000 CY of unsuitable materials off site and approximately 5,500 cubic yards of additional material were imported to the site to replace pOOT materials encountered in the trench and roadway beds. In addition, 11,250 cubic yards ofrnaterials were removed from the sewer trench and ''wasled'' on non-loadbearing slopes within the project area where possible in lieu of hauling away. The ''wasting'' of trench excavation materials involves more equipment time and labor than a standard trench backfilling operation and is equivalent to work that would normally be paid as common excavation. The cubic yard unit price agreed to for wasting the unsuitable trench materials is $2.25. (the contract unit price for common excavation was $2.70 which itself is on \he low end of the typical range). The cubic yard unit prices agreed to for hauling excess materials ranged from $3.80 to e $4.20 (these unit prices are on the low end of the typical range).
