Transportation Committee
FROM: Bob Giberson, Public Works Director
DATE: September 20, 2013
SUBJECT: Southcenter Parkway Extension Project
Project No. 98410437, Contract No. 10 -065
Project Completion and Acceptance
ISSUE
Accept contract as complete and authorize release of retainage.
BACKGROUND
The total project budget of $22,341,354.64 was approved along with eight (8) contracts at the May 17, 2010 Regular Council
meeting for the Southcenter Parkway Extension (SPE) Project. A 15% construction contingency was also approved for
$2,404,505. The Notice to Proceed for Contract No. 10 -065 with Scarsella Brothers, Inc. of Seattle, Washington was issued on
July 8, 2010. The SPE Project constructed approximately 7,400 linear feet of street improvements on Southcenter Parkway
from South 180th Street to South 200th Street, and roughly 3,000 linear feet of new sewer and water facilities on Southcenter
Parkway from Minkler Boulevard to South 180th Street. The overall work items included building demolition, grading, asphalt
paving and overlay, curb, gutter, sidewalk, storm drainage system, sewer system, sewer lift station, water system, traffic
signal, illumination, landscaping, irrigation and retaining wall.
ANALYSIS
Construction was physically completed on February 26, 2013. Thirty -one (31) change orders were executed for the project.
The majority of the cost increases were due to the Nationwide 14 Permit approval delay, the United States Army Corps of
Engineers' decision on revisions to the Tukwila 205 Levee, and compliance with current ADA standards. Refer to the
attached Change Order Log and Lessons Learned Report describing each change order and background for the major
changes. Unit price under -runs were due to force account items not completely utilized during construction. A retainage
bond was used by Scarsella Brothers for the SPE Project.
RECOMMENDATION
Council is being asked to formally accept and authorize the release of the retainage bond, subject to standard claim and lien
release procedures, for the SPE Project with Scarsella Brothers, Inc. in the final amount of $18,602,159.72, and to consider
this item at the October 14, 2013 Committee of the Whole meeting and subsequent October 21, 2013 Regular Meeting.

Southcenter Parkway Extension Project
LESSONS LEARNED REPORT
September 2013
Project History
The City of Tukwila (Tukwila) contracted with David Evans and Associates, Inc. (DEA) in the
spring of 2004 to prepare construction documents including plans, specifications, and cost
estimates (PS &E) for the construction of the Southcenter Parkway Extension (SPE) Project.
The project scope included replacing the existing two -lane roadway with a new five -lane
roadway from South 180th Street to South 200th Street. The new roadway section now
includes a five -lane roadway (two lanes in each direction with a center two -way left -turn lane)
with curb, gutter, and six -foot sidewalks on both sides of the road. Other improvements
included an enclosed storm drainage system, detention and water quality facilities, traffic
signal upgrades, illumination, utility relocations, channelization, signing, and enhanced
wetland mitigation areas.
In 2009, Tukwila and Segale Properties entered into a development agreement that sets the
stage for new development in the area now known as Tukwila South. Segale owns the
majority of the land in Tukwila South that is adjacent to Southcenter Parkway between South
180th Street and South 200th and is constrained by the Green River and Interstate 5. Segale
is currently in the clearing and grading phase of developing their land into mixed -use facilities
that will include commercial, industrial, and residential uses. In addition to new roadway
improvements, the decision was made to extend the water and sewer improvements on
Southcenter Parkway up to Minkler Boulevard from South 180th Street, since the new sewer
tied into the Tukwila South improvements.
Tukwila finished bid documents in early 2010 and advertised for bids. A construction contract
was awarded to Scarsella Brothers, Inc. (SBI) at the April 19, 2010 Council meeting. The
construction contract Notice to Proceed (NTP) was issued to SBI on July 8, 2010.

Contract Changes
Dozens of contract changes occurred during the construction of this large and very difficult project.
Most of the contract changes were small and were handled administratively without change orders
using unit price bid items and force accounts. The major construction contract change orders are
listed below and explained in full detail later in this report:
• Change Order No.
• Change Order No.
• Change Order No.
• Change Order No.
• Change Order No.
• Change Order No.

13 — Sewer trench - $497,718.14
17 — Nationwide Permit 14 Delays - $294,080.00

26 — Nationwide Permit 14 Delays - $373,695.97
31 — Nationwide Permit 14 Delays - $600,000.00
Change Order Nos. 12 and 13
Change Order Nos. 12 and 13 are interrelated due to the sewer trench sloughage caused large
sections of existing sidewalk to collapse into the trench. The construction management consultant
performed a detailed field review of the existing conditions of existing curb, gutter, and sidewalk along
the length of the project, from Minkler Boulevard to South 180th Street. During this review, the
conditions of the existing ADA ramps at intersections and driveway were inspected. FHWA Policy and
the Americans with Disabilities Act (ADA) of 1990 require that ADA compliant pedestrian facilities be
provided on highway improvement projects and /or preservation projects. These inspections
determined the ramps and driveways did not meet current ADA requirements.
Tukwila contacted WSDOT to determine which ADA items were required for compliance when an
overlay project is performed. The response was to upgrade the ADA ramps only. Standard driveway
aprons do not need to be upgraded unless the work to be performed includes
construction /reconstruction of the concrete driveway. At -grade (asphalt) driveways with ADA ramps
do need to be upgraded. The final plans for this scope of work were revised to reflect this
recommendation by WSDOT. The ADA ramp and sidewalk changes amounted to $276,085.00.
In addition, during the excavation of the new sanitary sewer between South 180th Street and Minkler
Boulevard, very unstable soil conditions were encountered that led to excessive sloughing, and
collateral damage to neighboring utilities, curb, sidewalk, and other items. The original bid documents
did not provide any geotechnical data in this area, which would have given a clearer picture of the
subsurface conditions. In conjunction, the plans did not require structured shoring, which could have
limited the amount of sloughage and over excavation, thereby limiting the curb, gutter and sidewalk
damage. These change orders provided compensation for repair and replacement of curb, gutter, and

sidewalk sections damaged during the sanitary sewer work. This restoration work was also
incorporated into the final plan set for compliance with ADA requirements. The additional sanitary
sewer trench work changes amounted to $497,718.14.
Change Order No. 19
The approval of the United States Army Corps of Engineers (USACE) 408 permit would have allowed
the "Cross Valley Levee" to be removed. In January of 2011, Tukwila was notified that the USACE
would not be approving the extension of the Tukwila 205 levee from the Cross Valley Levee down to
South 200th Street. Because of this USACE permit denial, and that the new levee between the Cross
Valley Levee and South 200th Street was not going to be certified, the road and utility crossings over
the existing Cross Valley levee had to be re- designed to meet USACE Section 208 requirements. The
original design was based on a decertification, so a revised design was coordinated to allow the levee
to remain intact. The USACE approved the re- designed roadway profile and utilities that basically
went up and over the levee with minimal impacts, but the construction changes cost $252,764.00.
Change Order Nos. 17, 26, and 31 (Stream E Delay Claim)
SBI submitted an extensive and complicated delay claim due to the project impacts of
shutting down the areas surrounding Stream E (refer to Exhibit 1). The three (3) change
orders are a result of ongoing negotiations and offers to settle the claim. One of the first tasks
in the construction contract included placing roadway fill material within Stream E. At the time
the construction contract was awarded, a Section 404 Permit that included the work for the
filling of Stream E, had been submitted by Segale Properties to the USACE. This 404 permit
was intended to cover the entire Tukwila South development and the SPE project. The 404
permit was under review by the USACE for more than a year. While issuance of the 404
Permit was anticipated prior to construction, there was contingency plan for the City to obtain
a Nationwide Permit 14 (NWP 14) if necessary. The roadway project was eligible for a NWP
14, which allows for limited filling of streams and wetlands related to linear transportation
projects. After reaching a critical point without any word on the 404 Permit, the City
subsequently submitted the NWP 14 application. During the week of August 9, 2010, the
contractor began filling Stream E without an approved NWP 14 and without following all
requirements in the Contractor provided NPDES permit and erosion control plan.

On August 19, 2010, the City of Tukwila's construction management staff was notified of the
error and halted all work related to the filling of Stream E. On September 24, 2010 the
USACE performed a site visit, noted the filling of Stream E that had occurred, and began an
investigation of a possible violation of the Clean Water Act. The investigation and subsequent
resolution of the violation concluded on March 9, 2011 by the issuance of an after - the -fact
NWP 14 Permit by the USACE. The resultant work to fill Stream E resulted in an approximate
6 month delay to the project. A delay of 121 Working Days (170 Calendar Days) is
attributable to the late delivery of the USACE Nationwide 14 permit.
Multiple claim negotiation meetings took place between Tukwila and SBI regarding the delay
claim and no compromise was reached between the parties. Eventually, a mediation date
was mutually agreed upon and scheduled by both parties in March 2013 to discuss the delay
claim in front of a mediator. Even with the mediation date scheduled, and a mediator
established, the City and SBI continued to talk and try to settle the delay claim. After many
exchanges between the two sides, a final settlement of the delay claim for $600,000 was
reached in the late evening on February 26, 2013 (right before the agreed upon mediation
date).

Lessons Learned
1. INVOLVE WSDOT EARLY
The large ADA Change Order No. 12 taught us to involve WSDOT Local Programs and their
ADA experts early and often, to avoid expensive field re- designs and change orders. This
lesson learned is being applied to upcoming projects.
2. OBTAIN MORE GEOTECHNICAL DATA DURING DESIGN
The large sewer trench Change Order No. 13 taught us to obtain as much geotechnical
information during design as possible, to make sure we get strong trenching, shoring and
dewatering specifications in place anywhere there is a chance for a trench over 4 feet deep.
For trenches deeper than 6 feet, even more soils testing and analysis should be done as the
risk of sloughage increases with the depth of the trench. Extensive geotechnical and potholing
advance investigations were performed on the Interurban Avenue South Gravity Sewer project
and that project was under budget.
3. LEARN AND UNDERSTAND PERMIT REQUIREMENTS
Change Order Nos. 17, 26, and 31 taught us valuable lessons regarding Nationwide 14
permits. Lisa Verner, the former Tukwila South /SPE Project Manager had warned Public Works
staff and our consultants to pay close attention to the need for a NW 14 Permit if the 404
blanket permit was not approved by the construction start time. The NW 14 Permit now has a
special 45 day waiting period, whereas in years past, you could submit your NW 14 Permit and
immediately go to work. That condition is no longer valid and needs to be explained and
emphasized to all involved. City staff and the construction management consultant mishandled
the permit application.
Recommendations
For any and all similar construction projects, all staff and consultants need to be fully trained in issues
regarding ADA ramp requirements, geotechnical issues for deep sanitary sewer trenches, Nationwide
Permit 14 conditions, and anticipating issues with large Development Agreements.
The Southcenter Parkway Extension Project was the most difficult construction project ever
undertaken by Public Works and the end result is something the City and its partners can be proud of,
despite the challenges that were overcome.
