City Council Meeting Minutes May 16, 2006 Page 8 of 12 APPROVE AMENDMENT TO CONTRACT WITH SEH FOR ENGINEERING SERVICES FOR DILLON ROAD Mayor Sisk requested a Staff presentation. Public Works Director Phare reported in January of 2005 the City entered into an agreement with Short Elliott and Henderson, Inc. (S.E.H.) for Professional Engineering Services for Dillon Road reconstruction in the amount of $289,589. The work identified an effort to prepare plans and specifications for two different phases of Dillon Road reconstruction. At the time the contract was entered, Dillon Road west of 96th Street would be reconstructed in 2005 and Dillon Road east of 96th Street would be constructed in 2006. Since then there has been changes to the two year project timeline and Staff requested changes to the scope of work in order to properly staff the project during periods of reduced staff availability. Currently, all work by S.E.H. on Segment II (Dillon Road east of 96th Street) has been suspended to confirm drainage facility requirements. Until a revised scope of work can be clearly defined no additional design work will be undertaken on Segment II. The contract for Segment II work will be negotiated later this year. S.E.H. was requested to undertake additional design efforts and supplement City Staff beyond the original scope of work contained in their contract. The City requested the additional work for 88th St. and Dillon Rd. and associated signal relocation. Based on geotechnical findings Staff directed the design be changed to full removal of existing pavement, stabilized subgrade and full depth asphalt pavement instead of resurfacing the existing roadway. S.E.H. has requested additional fees of $23,000 for this work. Because the Dillon Road project between 88th St. and 96th St. was originally planned in two segments, the City budgeted for the project over a two-year period. This required an additional bid package of plans and specifications for which S.E.H. is seeking reimbursement of $21,200. S.E.H. is also requesting $2,500 to cover salary increases for the extended schedule period into 2006. S.E.H, was also requested to take on additional design work originally anticipated to be done by staff. This work included coordination with utilities, Boulder County Open Space and local irrigators. S.E.H. has identified costs of these efforts as $14,250. The fee additions identified total $60,950. S.E.H. has agreed to reduce this amount by $13,200 to address items staff believes were S.E.H.'s responsibilities not properly addressed during roadway design. The balance $47,750 is the additional fee requested by S.E.H. for work completed to date on Segment I, Dillon Rd. from 88th St. to 96th St. Staff believes the construction activities can be managed by Public Works staff with limited assistance from the S.E.H. design team. However, some support during construction from S.E.H. will be needed.
