Possible changes in scope to reduce costs include itemizing road improvements (exempts most sales tax on labor equipment), eliminating water line upgrades to Foster Point and Poverty Hill, using native soil instead of new, imported gravel for foundation and backfill and eliminating Foster Point sidewalk.

This memo addresses areas of cost savings that will be realized through changes in the plans and specifications. BACKGROUND In the year 2000, the City of Tukwila began design of sanitary sewers for the AllentownfFoster Point neighborhoods of Tukwila. The funding source was to be City monies and a low interest loan from the Washington State Public Works Trust Fund Board. The loan was secured in the spring of 2004, with construction slated for late 2004 and 2005. Ai....ALySIS City staff and their consultants have reviewed the plans, specifications, and the new Geotechnical Engineering Study by HW A GeoSciences. The following items will be revised in the redesign and re-bid: 1) No Sales Tax on Road Material (RuIe 171). 2) Eliminate water line upgrades between Foster Point and Allentown along the river (continue to use WD 125 lines). 3) Revise pipe trench sections to eliminate the use of new, imported foundation gravel and allow use of native soil. 4) Revise pipe trench sections to allow native materials as backfill. The current detail requires new, imported gravel. 5) Eliminate sidewalks, curbs, and gutters in Foster Point. Replace with thickened edge pavement sections to direct drainage to proposed catch basins. 6) Eliminate the sanitary sewer line to the base of Poverty Hill. 7) Eliminate the water line upgrades to Poverty Hill. Make the upgrades a 2006 CIP item. Total Possible Savings Amount Saved $200,000.00 100,000.00 50,000.00 300,000.00 100,000.00 100,000.00 50,000.00 $900,000.00 These savings are dependent on the bidding climate and current workload of bidders. The savings are conservative and couId be greater if contractors bid this project aggressively. All indications are that the bidding climate is favorable and many contractors remain interested in this project. RECOMMENDATION For information.

Proiect Completion and Acceptance This contract caned for drainage improvements to five locations throughout the City. One project was eliminated due to the planned improvements on Southcenter Ph.'wy, which caused a reduction of 55,087.47. DL Asahara was slow on cleanup of their punchlist items, thus the deJay in closing out the project. Recommend move to Re!!ular consent a!!enda for approval. B. Generator InstaIJation at the Emer2:encv Operations Center. Project Completion and Acceptance Tnis contract instaIJed a generator to run the Emergency Operations Center (EOe) at the golf maintenance facility. Additional work was needed at a cost of 59,050.00, which included additional L&1 electrical requirements and Puget Sound Energy and their contractor PiJchuk for the relocation of the transfonner. There was no impact to the players at the golf course. Dave also asked about fueling vehicles in an emergency and what happens ifthe power goes out. Jim infonned him that we have worked with Pride Pacific on Interurban and have a hoo1..'l.lp for a portable generator for the gas pumps. Recommend move to Re!!ular consent a2:enda for approval. C. AlIentown/Foster Point "Vater & Sewer Improvements. Re-bid Cost Savin!!s lVleasures In Nov. 2004, bids came in approximately 5900,000 over budget and were rejected. We presented possible cost savings options to investigate. Since that time, we have done some additional geotechnical work on the soils. In the original contract, we had planned on clean imported fill for the trenches. We have now found that in some locations we will be able to use the existing native soil for backfiIJ (;';'3 & ;';'4). We wiIJ also implement this as a road project to have Ru]e 171 applicable (no sales tax). We were also going to take over Water District 125 customers in the Foster Point area and upgrade the water ~ 1,'.1' lines. WD 125 already has 8" water lines, so now the plan is to have aIJ of Foster Point in WD 125. X-- Foster Pt. \\~IJ then have an inCTease in water pressure since our customers were only serviced by 2-4" water lines. We will also eliminate the planned sidewalk in Foster Point and just do thickened edge on the curb, but we will put the Foster Pt sidewaU, as an additive in the bid. Fina]]y, no upgrades to the base of Poverty Hi]], which were planned due to construction in the area. Scheduled to advertise in February and hopefu]]y bids wiIJ be more favorable the second time around. Recommend move to Re!!ular for discussion and approval. D. "Vater and Sewer Rates Annual re\~ew of water and sewer rates as reported to the Association of Washington Cities. Some discussion on the utility rate package presented for the Council retreat. Committee requested that we get the sewer rates that were not submitted, especiaIJy from adjoining areas, as there were some question if the King County Metro charge was added or just the City charge was submitted to the survey. Information. R. Surface Water Rates Jim M. stated that with the huge amount of infrastructure added each year, the City rea]]y does not have a replacement schedule besides the CIP. Dave and Jim H. suggested that we should discuss rates at the retreat and proposed residential rates be 570.00 (35% increase) but keep commercial customers at a 20% increase as listed in the budget. Especially since the average residential rate is 585.00. Joan was hesitant about such a large inCTease. Information. Other Reported on flood conditions (s]ides at Ryan Hill near 1-5 access and SR-599 across from the SCL switch station). The City overall is fine even thought the Corps has the river very high. Also reported that there would be two lanes closed on S. ]80"' Sr underpass to construct underdrains. Re er board is up infonning drivers of four weeks of traffic disruption starting 217/05.
