J INFORMATION MEMO TO: Mayor Mullet FROM: Public Works Director DATE: March 19, 2003 SUBJECT: 2003 Bridge Inspections Consultant Selection Contract Annual Bridge Inspections Repairs ISSUE Approve consultant selection and authorize the Mayor to execute a contract with Sargent Engineers for bridge inspections and design of a bridge deck overlay for the Boeing Access Road bridge. BACKGROUND Three (3) consulting firms were rated on their experience and ability to provide routine bridge inspections and to provide design services for overlay of the Boeing Access Road bridge. The rating sheet is attached. Sargent Engineers scored the best and has satisfactorily provided services in the past for the City's Bridge Program. Six (6) of the City's bridges are required to have routine inspections performed in 2003. The Boeing Access Road bridge over the railroads is in need of significant bridge deck repairs. Sargent Engineers prepared the attached scope of work and estimate to provide the engineering expertise to accomplish both tasks. Additional work anticipated in 2003 includes scour evaluations for two (2) bridges. This expertise was included in the consultant rating process, but Sargent Engineers does not perform the diving necessary for the evaluations. CES, Inc., rated a very close second and does provide diving services for scour evaluations. Staff recommends using CES, Inc., to provide scour analysis later this year. ANALYSIS Sargent Engineers, Inc., has prepared a contract to provide design and bidding documents for the repairs to the deck of the Boeing Access Road bridge over the railroads. The scope also includes inspection of the six (6) bridges due in 2003. 2003 Buda et Proposed Contract Engineering 48,000 25,695 Right -of -Way -0- Construction 641.000 Total 689,000 RECOMMENDATION Approve consultant selection and authorize Mayor to execute a contract with Sargent Engineers in the amount of 25,695. attachments: Consultant Selection, Scope of Work, Estimate CONSULTANT SELECTION 2003 BRIDGE PROGRAM Staff Expertise 1 1.5 1 Bridge Deck Repair /Rehab. 1 2 1 Experience Bridge Inspection Program Management Tukwila Bridge 2 2 1 Program Knowledge Scour Analysis Expertise CES, Inc.

You have identified six bridges that need inspections and one bridge that needs maintenance. Based on our discussions, I have prepared the following scope of work. Bridge Inspections All inspections for the bridges shall be routine inspections and shall conform to the State of Washington standards for routine inspections and the reporting of routine inspections. Macadam Road Bridge This is a concrete slab bridge that requires a routine inspection. The bridge will be inspected from the ground below the bridge. We will not need any access equipment for the inspection. 51 Avenue Bridge This is a two span concrete box girder bridge. The center pier is a vee shaped pier with a small deck section between the vee. We will inspect this bridge from the ground and will not require any special lift equipment. South Grady Way Bridge This is a multiple span structure that crosses the railroad tracks. It located between Tukwila and Renton. We will inspect this bridge from the ground and will not require any special lift equipment. ENT Mr. Robin Tischmak Page 2 March 10, 2003 Boeing Access Bridge over Airport Way This is a four span concrete tee girder structure. We will perform the inspection from the ground under the bridge. No climbing or lift vehicles will be required. South 118th Street Pedestrian Bridge This is a glued laminated timber bridge that has three spans. We will use climbing methods to access and inspect this bridge. Green River Pedestrian Bridge This is a glued laminated timber tied arch bridge with a single span over the river. We will use climbing methods to access and inspect this bridge. Boeing Access Bridge Deck Repair The deck of the Boeing Access Road over the railroad tracks is deteriorating. You wish to repair the deck of the bridge. We see this happening in a two stage approach. In the first stage, we will survey the deck and get it tested if necessary. We will then prepare options for the repair of the deck. These options along with cost estimates will be presented to you for your evaluation. If you select an alternative, the next phase will prepare the contract documents for the repair. Our scope of work includes: Survey the deck for delaminations, bad concrete, rock pockets, and other deterioration. If needed, test samples of the deck for compressive strength, chloride content, and overall chemical composition. Prepare concepts and cost estimates for the repair of the deck. Prepare a report for the City to evaluate the repair options. If the City selects a repair option, prepare the plans, specifications, and estimate for the repair of the deck. The City will perform permitting and traffic control, if any is required. Cost Estimate In preparing our cost estimate, we assumed that we would inspect the bridges to the best of our ability using ladders and climbing techniques.

Three firms were rated for this project. Six bridges will be inspected, and the bridge deck of Boeing Access Road will be surveyed and options will be prepared for repairs. The budget for engineering is $48,000. The proposed contract is $25,695. Money from this budget will also be needed later to analyze the scouring on the Boeing Access Bridge. Recommend agreement with Sargent Engineers for $25.695 to a Regular Meeting. 2. Interurban Bridge Widening This project was bid last year, but all the bids were over the city's budget. Some project items were reduced, and the project was re -bid this year. One of the eight bids received was low enough to be able to move ahead with the project. The bridge will be widened to allow two left turns to I -405, and the Interurban Bridge trail design is included in this bid. The low bidder was C.A. Carey, whose references checked out. Award Interurban Bridges nroiect to C.A. Carey at a Regular Meeting. 3. Duwamish Parking Pam L brought up the issue of the street parking shortage in Duwamish which results when residences have many people over for a family gathering or a party. There were a couple of issues: whether private parking was allowed on a side street, and how to resolve the disagreement between neighbors about parking. Some apparently like the smaller streets with no parking. Others would like to be able to park when they have extra cars visiting their homes. Jim M suggested those with gatherings at their homes get a "D" type permit that allows parking on the streets. Jim suggested saying that the city built the street as the citizens had asked, and if they now want to change that, they need to petition the city or otherwise request the change. Pam thought a reasonable option would be to allow parking on one side of the street only, with no overnight parking. Pam thought if someone got a petition to allow parking it could appear to be a majority opinion, but could be the result of skewing the wording to make the alternative look unreasonable. She thought people should have both a parking and a no- parking petition to get both sides involved. Information. /155 Committee chair approval
