• <br /> <br /> An employee-owned company <br /> December 9, 2009 <br /> Mr. Kenny Nguyen, PE <br /> Senior Civil Engineer <br /> City of Santa Ana <br /> 20 Civic Center Plaza, M-36 <br /> Santa Ana, California 92702 <br /> Subject: SR-55/MacArthur Boulevard Interchange Ramp Widening Project <br /> Contract Amendment #2 (revised) <br /> Dear Mr. Nguyen: <br /> PBS&J appreciates the opportunity to submit this revised proposal agreement to the City of Santa <br /> Ana for approval of additional work necessary to update the SR-55/MacArthur Boulevard <br /> Interchange Ramp Widening Project (EA 0H2900). <br /> The purpose of the additional work effort is to include widening required on MacArthur Boulevard <br /> to adequately address the existing traffic operational issues. The original scope of work included <br /> widening the eastbound on-ramps with only restriping MacArthur Boulevard per attachment "A" <br /> per the City's RFP in 2007. <br /> The original scope of services only included restriping of MacArthur Boulevard; however, our <br /> detailed technical analysis determined that the existing width of MacArthur Boulevard is not wide <br /> enough to accommodate four general purpose traffic lanes with both left and right shoulders as <br /> required by Caltrans. This will require PBS&J to include additional plan sheets and details in the <br /> construction documents that were not originally included in the scope of work. Due to the previous <br /> work efforts put forth for this project the current budget is not sufficient to complete the project <br /> with the additional work required to add the roadway widening on MacArthur Boulevard to the <br /> plans, specifications and cost estimate. Therefore, PBS&J is requesting a contract amendment in the <br /> amount of $45,000, $35,000 for PBS&J's effort and $10,000 for additional survey on MacArthur <br /> Boulevard by Towill. <br /> Per our ongoing discussions our request for additional fee is based on the following assumptions: <br /> ¦ A full hydraulic/hydrology report is not necessary for this project. Basic calculations with new <br /> tributary areas and a memo indicating that water is not backing up to Caltrans right-of--way is <br /> sufficient. <br /> ¦ The drainage and contour grading plan sheets will be combined. <br /> ¦ Utilities will be shown on the layout sheets to eliminate separate utility sheets. <br /> ¦ The signing and pavement delineation sheets will be combined. <br /> ¦ Water pollution control plan sheets will not be required. However, the water pollution control <br /> items of work must be in the Caltrans Special Provisions, in the Summary of Quantities plan <br /> sheets and in the project cost estimate. The Caltrans Standard Plans will provide the plan sheet <br /> information. <br /> 625 The City Drive South • Suite 200.
