B " aj as Mayor ATTEST: APPROVED AS TO FORM: .�.�� �(�� .� Debra Barham, CMC Kerr Fer� aw, PLLC City Clerk City orneys Resolution—Lewis Street Overpass Project-CO 8- 11 with Cascade Bridge,LLC. -2 EXHIBIT A Lewis Street Overpass Project Contract Change Order Summary • Change Order No. 1: Office Trailer for Construction Management Team, $38,711.58 This change compensates the contractor for providing the Construction Management team with an on-site 12x56' trailer with work areas and a dedicated meeting room for regular project meetings. Pricing includes all associated costs such as heat/ac and setup and removal. This change order covers 24 months of use. Contractors such as Cascade Bridge, LLC. receive significantly better pricing than infrequent users like the City or the construction management team. Pricing from the construction management team was compared with contractor pricing and the most cost-effective option was for the contractor to supply the trailer. • Change Order No. 2: DBE COA Deletion, $0 WSDOT errored in requiring a Disadvantaged Business Enterprise (DBE} Condition of Award (COA) requirement of 7% even though it should not have been required by the funding source. This change reduces the DBE goal to 0% and reduces the apprentice training hour requirement from 2,000 to 0; however, the DBE firms associated with the project are still perForming all anticipated work. • Change Order No. 3: BNSF Crossing Permit, $100,000 This change order is required for the contractor to construct required crossings over BNSF rail tracks. BNSF requires concrete panels and fencing be placed at a designated crossing to protect the tracks and decrease the likelihood of improper crossings. To protect the City from added risk associated with an incident at the crossings, the contractor was required to obtain the crossing permit and is reimbursed for actual costs per the contract specifications. • Change Order No. 4: Girder Embedded Plates and Sole Plates, $33,112.33 Girders on spans 1 and 4 of the Lewis Street Overpass bridge were originally designed with bearing recesses befinreen 1/8" and 7/8". Due to required reinforcement spacing in the pre-stressed girders, most of the girders required reinforcement modifications and additional reinforcement (rebar and plates) to provide the structural bearing capacity. This change order compensates the contractor for materials and labor to modify the structural reinforcement. • Change Order No. 5: Added Drainage and Drywell at Bridge Abutments, $16,915.44 During design of the project, an expansion joint was modified by the Engineer of Record. As the result of the bridge expansion joint modification, additional perforated drainpipes, trenches, and drywells were required at each of the BNSF Bridge abutments. This change order compensates the contractor for all costs associated with providing the new drainage features. • Change Order No. 6: BNSF Force AccounUMinor Changes, $20,000 BNSF requires the City and Contractor to complete/provide many small, unforeseen items on the project (minor grading, placement of small amounts of materials, adding security fencing, relocating utilities, etc.). The existing Overpass Agreement allows BSNF to direct work as they deem necessary to maintain safe operations. This change order reimburses the contractor for this work on an actual costs basis per the contract specifications. • Change Order No. 7: Replace Waterline —Alley C 8� D, $144,669.34 The City of Pasco requested the replacement of the existing waterline in Alleys C and D; and the installation of a new fire hydrant on First Ave. near Abutment 1. The City stated this work should be performed if it would not impact the critical path. Cascade Bridge agreed to perform the work and began by removing asphalt in Alley D on May 11, 2022, and concluded work on May 31, 2022, by backfilling the final connection at Alley D and Clark St. • Change Order 008 — Removal of Fuel Tank, $29,206.78 On May 10, 2022 KLB began excavation for SEW Wall's 1 and 2, and identified two abandoned fuel storage tanks which were unknown until discovery. Removal of the tanks was required to construct walls leading to the new Lewis Street Overpass Bridge. Cascade Bridge contacted GeoProfessional Engineers (GPI), the Geotechnical engineer subcontracted by prime consultant JUB Engineers, to manage the removal, reporting, and clean-up of the tanks. WSP subsequently directed Cascade Bridge and subcontractor KLB Construction (KLB)to remove the two tanks per GPI direction. KLB supported GPI in excavation and removal. All costs were tracked by force account under the minor change item (A161) since the total scope of work to be completed was evolving as work was completed. • Change Order 009 - Unexpected Site Conditions — Subgrade, $210,949.77 In September 2021, KLB began excavation for BNSF Abutment 1, and discovered foundation walls from the previously demolished hotel were remaining. KLB removed minor portions of walls where they impacted the footing for the bridge abutment but did not perform any additional exploration since this was believed to be a localized issue. In April 2022 as KLB was removing sidewalk and beginning excavation for SEW Walls 3, 4, 7 and 8, the following were discovered: 1. Pockets of lose fill material below the footprint of the old hotel, unsuitable to build over. 2. Concrete foundation walls from the old hotel. 3. Significant pockets of inorganic debris from the removal of previous structures. 4. A tunnel and concrete staircase beneath/adjoining the existing sidewalk at Tacoma/Lewis where future parking is planned. After discussing the issue at length with the SEW wall designer and prime consultant, JUB Engineers, it was determined all debris, lose fill and old structures would need to be removed for wall construction. The existing soil and voids were replaced as required using crushed rock and concrete for SEW Wall construction. This item was not previously brought in front of council for two reasons. First, there was no option to complete this work. Based on the recommendation of the geotechnical engineer, wall designers, and bridge designer, the four items listed above had to be removed. Second, the full extent and cost of removal was unknown until excavation could be completed. Items such as amount of removal, use of reinforcement, depth of removal, etc. was unknown until the work could be performed. • Change Order 010 - Schedule 80 Conduit and Trenching, $36,559.01 Per Request For Information (RFI) no. 025 response from JUB on 7/20/21, the Contractor was directed to use Sch 80 electrical conduit and increase the depth of the trenches below the SEW Walls so that there would be 4' between top of conduit, and bottom of SEW Wall. This change includes compensation for having to procure the conduit when the Franklin Public Utility District (FPUD) had committed to providing conduit. FPUD was unable to provide conduit as anticipated for the project because they do not stock schedule 80 conduit. The subcontractor performing the work, Neppel Electric & Controls, Inc., provided a quote to obtain materials; but due to extremely volatile pricing from conduit suppliers, pricing was only held for 24 hours. Due to the volatility in obtaining the materials and the depth required by the design engineer, it was imperative to provide approval to do this work immediately. • Change Order 011 - Extra Waterline Work, $13,925.36 While installing waterline and performing temporary and permanent connections on the east side of the underpass, KLB identified several connections that required extra fittings to be able to tie-in as existing waterlines were not per plan. This work was tracked as force account work but, there is no minor changes item in Schedule C to pay for this work, resulting in a change order.
