The narrow pavement precluded the contractor's option of building one-half of the pavement section and then maintaining two-way traffic on the newly constructed section while the remaining half of the pavement was constructed. The 27 -foot wide pavement section required that half of the roadway be constructed while a temporary asphalt detour lane was constructed and used to maintain two-way traffic north and south. Included in the change order are the following items: • The deep cut in the roadway grade, particularly just south of the Parr Road / Parr Lane intersection, required a number of detour implementations, traffic re-routing which significantly impacted the final cost of the asphalt detour. The added asphalt lane was the only choice for the project to provide adequate access to the two neighborhoods at the far north end of Parr Road (that have no other access). The area around the Parr Road / Parr Lane intersection is the location where the need for the added temporary paving was most required ($37,209.60). • The installation of additional sanitary sewer lines to provide for sewer to the existing homes on the north side of Parr Lane at the intersection with Parr Road as well as the ability for properties just north of O'dell Court to be served by sewer at the time they choose to connect ($ 20,424.20). hQ, • Storm drainage and water connections to the Walker Estates Subdivision which was not in place at the time of the construction plan preparation for Parr Road ($17,670.00). • Localized yard drainage systems to collect surface water and 700 feet of under -drain to collect groundwater encountered along Parr Road ($ 18,473.75). • Additional parking spaces and concrete drive surface in the vicinity of the entrance drive into Parr Park ($78,373.65). • Miscellaneous adjustments ($ 8,508.78). Staff recommends approval. JSL/dsm 0:\agenda\040202\Pa rrRd_ChangeOrder_l . agm March 28, 2002 (8:30AM) CITY OF GRAPEVINE CONTRACT MODIFICATION AGREEMENT W.T.
