Title
Resolution to Approve Amendment No. I to a Professional Services Agreement with Parsons-Brinckerhoff Michigan, Inc., for the Huron Parkway Bridge Painting and Huron Parkway/Geddes Avenue Intersection Improvements Project ($128,641.54)
Memorandum
Attached for your review and approval is a resolution that will approve an amendment to our Professional Services Agreement with Parsons-Brinckerhoff Michigan, Inc. (PBM) in the amount of $128,641.54 for project management, professional engineering, and construction inspection services performed in conjunction with the subject project.
During the course of the project, it became necessary to add additional services to our agreement with PBM in order to properly complete the work of the project. These services and their approximate costs are described as follows: re-designing, inspecting, and providing construction claim analysis services regarding the steel repairs that were performed on the bridge portion of the project ($99,500.00); providing additional testing of high strength steel bolts in order to assure compliance with all state specifications ($5,800.00); providing construction engineering services for the portion of bike path along the west side of Huron Parkway between Geddes Avenue and E. Huron River Drive (this work was added after the construction contract and professional services agreement was awarded) ($10,100.00); re-designing certain roadway elevations to provide better drainage ($6,000.00); and re-designing certain sidewalk alignments and ramp grades to better comply with ADA Standards ($7,200.00).
Sufficient unobligated funds exist within the contingency line item of the project budget to cover the cost of the services being requested here.
PBM has received the necessary human resources approval and pays its employees a living wage.
Project Update
The intersection of Huron Parkway and Geddes Avenue was opened to traffic in late September and the intersection had the final layer of asphalt placed and the striping performed in early October 2007. All steel repair work was completed on February 28, 2008.
During the course of the construction of this project, we discovered that portions of the neoprene seal that we had installed in the center joint that runs the length of the bridges was coming out. Our investigations revealed that the bridges were deflecting more than the specified seal could withstand and forcing the neoprene seal out. As a result, we decided that it would be necessary to revise the design of the joint and re-install it. Unfortunately, in order to perform this work, the weather must be warm enough to allow the materials that the revised design requires to be installed properly. It was not possible to repair the center joint during the winter months when the center lanes of the bridge were closed to perform the steel repairs.
Currently, because of the cold weather that we've experienced, it now appears that we will be able to perform the work sometime in late-April to mid-May. When the work is performed we will close the center lanes of the bridge during non-rush hour times to allow the workers to install the joint.
Once the center bridge joint is repaired, all major items associated with this project will be completed.
