Please contact the Public Works Department at 206 433 -0179 for assistance. p City of Tukwila Jim Haggerton, Mayor INFORMATIONAL MEMORANDUM TO: Mayor Haggerton Transportation Committee FROM: Public Works Director DATE: April 1, 2011 SUBJECT: Tukwila Urban Center Access (Klickitat) Proiect Project No. 98410419, Contract No. 10 -120 Project Acceleration Change Order ISSUE Discuss approval of a change order to compensate the contractor to accelerate the project by an additional 43 calendar days. BACKGROUND The contract with Atkinson Construction for the Tukwila Urban Center Access Project was executed in January of 2011. The contract includes incentives and disincentives to ensure that the construction is completed before the holiday season. The disincentive allows the City to withhold $25,000 per day from the Contractor's final payment for each day the road is not opened after November 16, 2011. The incentive requires the City to pay $25,000 per day to the Contractor for each day the road is opened before November 1, 2011 up to a maximum of $250,000. (This cost is already included in the project budget.) The Contractor's proposed project baseline schedule was approved on March 11, 2011. This schedule has an early completion date of October 13, 2011 (October 13 is counted as a work day in the current schedule with the roadway expected to open after work is complete on that day). The schedule assumes a work week of five days per week and eight hours per day. The Contractor did not propose to use weekends, nights, or longer shifts to accomplish the construction work. DISCUSSION Throughout the public outreach process, staff has entertained questions and concerns about the length of the closure and whether there was a way to get the southern 1 -5 off -ramp open earlier. However, the construction sequence requires that this ramp be one of the last pieces of the job to be constructed. In short, this is because the entire wall between this ramp and the adjacent lanes must be constructed first. Then a concrete cap is placed on top of that wall and this cap is essentially a moment slab that supports the concrete barrier that is constructed between the ramp and the adjacent lanes. This concrete cap extends underneath the asphalt for the southern 1 -5 off -ramp. The ramp cannot be opened until the wall, the cap, the barrier, and the asphalt are all complete. After several discussions with the Contractor, there is an opportunity for the City to pay for acceleration beyond the incentive provided in the contract. The Contractor has reviewed his schedule and the contingencies that ensure that the construction is completed by his proposed date of October 13 The Contractor's analysis indicates that if he works longer days and adds Saturdays, and potentially Sundays to his schedule, (barring any unforeseen changes or weather delays) he could reopen the entire road by September 1, 2011 (early morning). The added cost to work the additional overtime cost has been estimated to be $11,000 per day. W:12011 Info Mennos\Urban Access MayorMEM CO #03 03 26 1 1.doc INFORMATIONAL MEMO Page 2 Additionally, there is a one -time cost for the Contractor to revise the project schedule and make necessary changes to accomplish the new schedule at an estimated cost of $20,000. The Contractor would begin incurring both of these expenses immediately upon approval of this Change Order. There is no guarantee that the contract would be complete ahead of schedule; however, the Contractor would only be reimbursed the $11,000 per day of early completion prior to the current scheduled opening day of October 13, 2011. Therefore, this is a strong incentive for an early completion. If the City were to cause delay to the Contractor by making changes or due to unforeseen conditions, the City would have to compensate the Contractor for the $11,000 per day acceleration cost. The maximum cost for this Change Order would be $493,000.00 (or $11,000 per day for 43 days, plus the $20,000 scheduling cost). Construction Management costs are not expected to change because the contract was executed prior to the construction contract in which a few months of night shift work was anticipated. These hours will be applied to the longer days and Saturdays in this Change Order proposal. This minor increase to the LID has been brought to the attention of as many of the businesses in the Southcenter area as possible. The cost for this acceleration proposal would add $493,000 to the project cost which would work out to a cost per property of between $0.02 and $0.04 per square foot of land depending on the property's type and location. As an example, for a 100,000 square foot lot (about 2.5 acres) this would range from $1,000 to $2,000 (or $67 to $133 per year). The funding for this acceleration proposal would come from the Local Improvement District (LID). Because the construction bids came in lower than predicted, the Preliminary Assessment Roll has capacity to absorb some of the additional cost for the proposed acceleration. The increase to the Preliminary Assessment Roll (which would be less than the project cost) would be approximately $247,000 or between $0.01 and $0.02 per square foot of land. As an example, for a 100,000 square foot lot (about 2.5 acres) the increase in assessment as compared to the Preliminary Assessment Roll would range from $1,000 to $2,000 per year. The attached spreadsheet shows some examples of the assessment increase. Many businesses have expressed significant concern over the impact this project may have, especially during this difficult economic period. Staff has reviewed this acceleration proposal and recommends approval of this Change Order. RECOMMENDATION Council is being asked to consider this Change Order and any input received from affected business and property owners. Based on that input, Council is being asked to authorize the Mayor to execute this Change Order to accelerate the construction of this project in the amount of $493,000.00 and forward this item to the April 4, 2011 Regular Meeting (same night) for consideration.
