BACKGROUND In June 2011, the City issued a Request for Proposal for the 40 -42 Ave S roadway widening project between Southcenter Blvd and S 160 St. In addition to the roadway project, the call for proposals included design work on the 42 Ave S culvert for Gilliam Creek. This culvert is in poor condition and needs either significant repair work or a full replacement In August 2011, three consultant teams were interviewed in a competitive process after being short listed from seven RFP's that were received. The teams interviewed were CH2MHill, Skill ings- Connolly, and KPG. The consultants were scored by the selection panel and CH2MHi11 and Skillings- Connolly were in a virtual tie. Reference checks were performed with no negative feedback on either firm, although more positive feedback was given for CH2MHill; leading to CH2MHill being chosen. Since then, staff and the consultant have been negotiating the scope and fee. As staff was negotiating with the consultant, it became clear that the amount in the 2011 budget was inadequate to complete full design. A modification to the CIP sheet was made to increase the budget amount to $650,000.00 prior to the December adoption of the 2012 CIP. DISCUSSION The scope of work includes full design for both the roadway improvements and the culvert replacement, up to and including support during bidding. Cost for the roadway design is $606,916.00 and the culvert design is $120,079.00, for a total contract amount of $726,995.00. Engineering for roadway design does not include costs to convert the overhead power and phone lines to underground vaults. Task 5.3.2 is included where the Consultant team will analyze the costs of converting the overhead utilities vs. remaining aerial. Council will be informed of this undergrounding analysis. If a decision is made to underground aerial utilities, the design contract will need to be supplemented to include the optional tasks 5.3.3 (30% Design) and 9.5.2 (100% Design). The cost for a future undergrounding design supplement is estimated to be approximately $72,700.00. Fiscal Impact: Roadway work is budgeted in the 2012 CIP at $650,000.00 (pg. 2). Inclusion of the design for the overhead utility conversion will require additional budget which will not be known until a later date. Culvert design work is budgeted at $125,000.00 (Gilliam Creek 42 Ave S Culvert, page 146, 2012 CIP). RECOMMENDATION Council is being asked to approve the contract with CH2MHill in the amount of $726,995.00 and consider this item at the January 23, 2012 Committee of the Whole and subsequent February 6, 2012 Regular meeting.

(CONSULTANT) shall perform professional services for the City of Tukwila (CITY) in connection with the following project: 40th 42nd AVENUE SOUTH PHASE III Project Description The 40th -42nd Avenue South Phase 3 Project includes roadway widening, asphalt overlay and replacement, curb, gutter, bike lane/ sharrow, sidewalks, lighting, storm drainage facilities, utility relocations, and analysis of a fish passable culvert crossing for Gilliam Creek. The 1992 Design Report information will be updated to reflect current conditions, criteria and costs. Additionally, the City has chosen to incorporate other elements into the project that provide consistency with City planning efforts and with current regulatory requirements. These include: accommodating bicycles via a bike lane and sharrow lane; analyzing the replacement of Gilliam Creek culvert with a fish passable culvert; managing stormwater to meet King County Level 2 flow control requirements; and evaluating undergrounding of utilities. These additional design elements will be incorporated into the Final Design. The updated report will also document current applicable state and /or federal agency requirements and permitting needs. The elements of work for the design phase include: project management, roadway /civil /non- motorized, utilities, Gilliam Creek culvert, survey /mapping, stormwater, traffic, geotechnical, structures, illumination, community/ agency coordination, landscaping/ urban design, cost estimating, construction staging, right -of -way (ROW) determination, specifications, and quality review. Environmental and ROW acquisitions may be added later by supplement at the request of the City. Project Limits This project provides improvements along 42nd Avenue South from S. 154th Street to S. 160th Street. The side streets will be improved to provide a transition into 42nd Avenue South. The project also includes the analysis of a fish passable culvert crossing for Gilliam Creek whose limits are assumed to extend approximately 200 ft upstream and downstream of the existing culvert. This scope of work includes hydraulic analysis of Gilliam Creek beyond this 200 ft so that hydraulic constraints and hydraulic impacts of culvert alternatives can be assessed. 53 Assumptions The following general assumptions are made in developing the Scope of Work and Budget for 40t" 42nd Avenue South Phase III Project. Additional detail is included in the task descriptions contained in the remainder of the Scope of Work. General Assumptions 1. This AGREEMENT has contract duration of 18months. CONSULTANT'S ability to meet the completion date is contingent upon timely receipt of information from the CITY and others and provided the scope proceeds as outlined and within the timeframe above. 2. Before it can be built, this project will require a SEPA Determination of Non significance (DNS) based on completion of a SEPA Environmental Checklist. It is assumed that federal funds and /or NEPA are not involved. 3. Right of Way services and SEPA and /or NEPA environmental documentation services are not included in this scope of work. 4. Unless otherwise specified herein, the CITY is responsible for paying for and securing any permits as well as securing all City permits. CONSULTANT assumes no responsibility for delays to the project as a result of the permitting process. 5. In providing opinions of cost, financial analyses, economic feasibility projections, and schedules for the project, the CONSULTANT will have no control over cost or price of labor and materials; unknown or latent conditions of existing equipment or structures that might affect operation or maintenance costs; competitive bidding procedures and market conditions; time or quality of performance by operating personnel or third parties; and other economic and operational factors that might materially affect the ultimate project cost or schedule. The CONSULTANT, therefore, will not warranty that the actual project costs, financial aspects, economic feasibility, or schedules will not vary from CONSULTANT'S opinions, analyses, projections, or estimates In soils, foundation, groundwater, and other subsurface investigations, the actual characteristics may vary significantly between successive test points and sample intervals and at locations other than where observations, exploration, and investigations have been made. Because of the inherent uncertainties in subsurface evaluations, changed or unanticipated underground conditions may occur that could affect total PROJECT cost and /or execution. These conditions and cost/ execution effects are not the responsibility of CONSULTANT. If there are changes in any of the Design Standards and References listed below, CONSULTANT may seek additional compensation if work performed needs to be altered or revised as a result of changes to design standards or references. 8. CITY will provide to CONSULTANT all data in CITY's possession relating to CONSULTANT's services on the PROJECT. CONSULTANT will reasonably rely upon the accuracy, timeliness, and completeness of the information provided by CITY. 9. CONSULTANT's deliverables are limited to the sealed and signed hard copies. Computer- 54 generated drawing files furnished by CONSULTANT are for CITY or others' convenience. Any conclusions or information derived or obtained from these files will be at user's sole risk. 10. A wetlands reconnaissance will be performed to determine if any wetlands are present. Should any wetlands be located that would be affected, a supplement maybe prepared to include a Wetlands discipline report and if requested Wetlands Mitigation report. The scope and cost estimate will be developed when requested. 11. The CITY shall provide or make available the following items to the CONSULTANT: The City of Tukwila Publications listed as "Design Standards and References" Existing GIS Mapping information of the Project including general utility location maps for CITY water, sanitary sewer, and storm drainage facilities. Copies of existing record drawing information of the project area. Existing survey horizontal vertical control in NAD 83/91 (Horizontal) and NAVD 88 (Vertical).
