Title (September 1I, 2093) Page 1 of 5 CITY OF TUKWILA Signature Title Attest/Authenticated: City Clerk Date Proiect Description EXHIBIT A -2 Addendum No. 2 Additional Scope of Work Allentown Water and Sewer Improvement Project Phase 2 The City of Tukwila desires additional design and construction management services for additional improvement to be provided as a part of this project. Engineering work would include the following items. Design "frontage improvements" to a portion of the 42 Avenue South corridor, from the northeast comer of South 124 Street to the southeast corner of South 116 Street; a distance of approximately 2,800 lineal feet. These frontage improvements will be located on the east side of this corridor and include concrete curb, gutter, and sidewalk (5- foot -wide) on the east side of the roadway. ADA compliant sidewalks will be reinstalled at their existing location. Minor (up to 3 feet or less) asphalt realignment (edge of existing) may be required (per City approval) to "best" accommodate new curb and gutter alignment. Design work will not include street or property right -of -way identification. This project will also require additional stormwater facilities. The stormwater facilities will be "tied" into existing culverts serving this area of 42 Avenue South. Existing systems currently known to serve the area will be incorporated into the design. No additional detention facilities are anticipated to be required. Treatment facilities are anticipated to include vortex or swirl treatment facilities. Fences, utility structures, mail boxes and/or project "impacts" adjacent to or within the existing sidewalk(s) will need to be temporarily or permanently relocated, as required. Driveways and yards may also need to be reconstructed onto private properties in order to accommodate any grade changes on vertical or horizontal realignment of the existing sidewalk(s). Additionally, drainage (yard drain) facilities will likely need to be added to facilitate changes in grade to, or adjacent to properties currently (surface) draining to public systems. In addition to these road improvements, additional curbs, gutters and sidewalks have been added to the 42 Avenue South corridor north of the South 116 Street intersection (east side). These were installed as part of the `recent" fire station improvements. Existing bid documents will be revised to show the location of these facilities to ascertain utility conflicts and reduce contractor claims for surface features not accurately shown, but impacted by existing alignment of facilities. The proposed vertical alignment (not horizontal) of the proposed sanitary sewer will be revised for approximately 750 feet to indicate an approximate 6 foot depth for proposed facilities in the South 115 Street corridor (west of fire station). Shallower gravity sewers have been determined to be feasible in this area to provide adequate sewer service. (September 11.2003) Page 2 of 5 Work will also include design modifications to the control/electrical panel for the lift station to accommodate the City's current standards. Plans and specifications will be updated with new engineer's stamp (existing license dates have expired). Additional revisions will include new specifications on roadway and drainage items, new and revised bid quantities (calculated as required), new construction details, new prevailing wage rate section, new project description, "call for bids and revised table of contents. Task No. Task Description Acquire additional survey information to include cross sections (half street) at approximately 50 -foot stations, in and along 42 Avenue South for a distance of approximately 2,800 lineal feet. Cross sections will also include partial driveway profiles and identification of critical "low spots" for identifying vertical information on "properties" fronting (and draining to) 42 Avenue South. Field work will also acquire information on the "general" location of existing sidewalk improvements built on 42 Avenue South as part of fire station improvements. 2. Provide conceptual, preliminary, and final design of new street frontage improvements to include "minor" roadway realignment (3 feet max.) to accommodate any new curb and gutter alignment. Provide plan view, typical cross section, and special construction details for sidewalks, curbs, and gutters. Provide plan view elevation grade "call- outs" on plans for new gutter panel elevation at 25 foot intervals, and around corner radii. Provide new stormwater utility design in plan and profile views. Incorporate applicable City review comments. This task assumes one meeting with City to discuss conceptual layout of street improvements. 3. Provide electronic revisions to plans for modifications to the control/electrical panel and associated items to accommodate current city standards. 4. Revise existing plan and profile drawings and detail sheets (no new streets added) to show revisions, additions, deletions, or modifications. 5. Revise and/or modify specifications to identify new work, deleted work, and modifications proposed herein. This task also includes calculating new and /or revised quantities. Work will not include adding or deleting schedules of work currently proposed. 6. Print and deliver to City a new set of revised bid/construction documents. Signed and stamped plans will be provided in mylar format with an electronic CADD file (2000). Specifications will be provided as a bound copy with electronic (Word) format. Provide two full size copies of each submittal (September 11, 2003) Page 3 of 5 listed above (see task item 2). Conceptual submittal will not include specifications. 7. Provide additional construction management services to facilitate the construction of the additional improvements. (September 11, 2003) Page 4 of 5 1. 2. 3. 4. 5. 6. 7.

Some are major projects that are planned for the future, such as connectivity or getting rid of the McClees property bought for vactor waste. Others are projects that were finished in 2003 including replacing carpets in the 6300 building, removing graffiti at Tukwila Pond Park, painting fire stations, and replacing the community center carpets. More painting at city buildings and roof coating the George Long building are active projects. Projects being designed for 2004 include the Council chamber project, which needs a list of possible decisions to help Council (and the Court and Planning Commission) choose what can be done. The committee recognized this was a policy issue, and thought it could be discussed at the Council retreat after it gets initial consideration at a Council meeting. There is also a long list of Future projects that are needed but not funded. Information. 2. Upgrade Pumn Station 19 Fort Dent There are two pump stations currently at Fort Dent, and neither has been properly maintained for years. One does not work at all, and the other is overwhelmed with water. Both pumps are old, and cannot be maintained. New pumps are needed, and it is not known whether the current gravity system will be adequate. PACE, Inc. was chosen from a short list of contractors. The contract will be for $41,742. Recommend PACE. Inc for design of Fort Dent storm drainage system. 3. Consultant for Strander Pine Replacement The storm drain pipes in Strander /Andover East and along Christensen Road and Baker Boulevard flood regularly with any big rain events. The pipes are too small, and need to be larger. There are many other pipes (including Olympic gas line pipe) in the vicinity, so replacing the pipes won't be easy. PACE was chosen to design the pipe replacement. The contract for preliminary engineering is $192,745. Dennis asked if it was feasible to pump the excess water to Tukwila Pond, and was told it was not. Recommend PACE to design nine renlacements in Strander. 4. Engineering for Phase 2 Allentown/Foster Point Sewers Designs for sewers as well as for water, street and some sidewalk improvements for Allentown/Foster Point have been done for both neighborhoods to the 90% level. The remaining 10% design remains to be done, and the two contractors (one for each neighborhood) will finish them, Gray Osborne will finish Allentown's design, and AHBL will finish Foster Point's. Pam L asked that staff look at both sides of 42 for the sidewalk to see which side was the better side to put a sidewalk on. A complicating factor is that the sidewalk now on the east side of the street badly needs repair, as it is dangerous for walking. Pam said dogs jump at the fence threatening walkers on that sidewalk. Staff said they would ask the neighborhood about which side they would prefer to put the sidewalk on when they have meetings there. Recommend authorizing contract addendums for design.
