190- INFORMATIONAL MEMORANDUM
TO: Mayor Haggerton
Transportation Committee
FROM: Public Works Director
DATE: April 1, 2011
SUBJECT: Tukwila Urban Center Access (Klickitat) Project
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.

INFORMATIONAL MEMO
Page 2
There is also a one -time cost for the Contractor to revise his 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 and that contract
anticipated a few months of night shift work. These hours will be applied to the longer days and
the 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.
