ACTION REQUESTED:
Request Commission authorization for the Chief Executive Officer to issue Change Order #030 
for the North Expressway Relocation (NER), Phase 1, Final Paving Landscaping and
Reclamation Project, to grant a time extension of 163 days for a revised contract completion date
of November 18, 2011, and in the amount of $17,178. No new funding is requested as funds

SYNOPSIS:
In April of 2011, the electrical inspector from the Washington State Department of Labor and
Industries (L&I) notified the contractor and the Port that he would not approve the new clock
tower electrical system because the solar power panels were not manufactured with an
Underwriters Laboratory (UL) label. The contractor had to get the solar power panels inspected
and approved by an independent third party in order to obtain the final electrical permit approval
from L&I. A change order is required to compensate the contractor for the costs incurred to 
resolve the electrical code issue and pay for the third-party inspection of the solar panels in the
amount of $17,178 and a time extension of 163 calendar days to address the additional time
expended to complete this scope of work and obtain final electrical permit approval.
The funds to pay for this change order come from the project construction contingency funds
previously authorized. No additional fund ing is being requested as a result of this change order.

BACKGROUND: 
This project is the last phase of a multi-phase North Expressway Relocation program to
reconstruct the North Airport Expressway and extend Light Rail Transit (LRT) to the Airport in
collaboration with Sound Transit. This project includes final paving of ramps near the parking
garage entrance and the Airport LRT station, landscaping, art features and clock tower at the
Airport north entrance, reclamation of staging and work area and miscellaneous work omitted or
deferred from previous North Expressway Relocation Phase 1 contracts. This project completes
the Port's obligation to Sound Transit to facilitate extending LRT to the Airport and to the City
of SeaTac for landscaping of Port property and restoration of facilities along city streets.
The new "Emerald City" entrance to the Airport is a key component to the North Expressway
Relocation program. This project includes various art components that have been selected by the
artist team to provide the desired aesthetics for the north entrance. The photovo ltaic system on
the south side of the clock tower is part of the art components and uses polycrystalline silicon
terrestrial photovoltaic cells that are a unique green color. These solar panels are only produced
by a single manufacturer that is located in Germany. A pproval was obtained for the solar panels
to be supplied by this sole-source firm. Since the panels come from Germany, they are
manufactured to comply with international electrical standards. Once the electrical installation 
was completed on the clock tower, the Port requested final approval by the electrical inspector
from L&I. Final approval was denied because the solar panels were not UL labeled.
The Port first requested that the contractor try to obtain a variance from L&I to accept the solar
panels based on the international electrical standards, which are equivalent to and have been used
in lieu of UL listings in some cases. Several months were spent in obtaining the documentation
for the variance. The state inspector ultimately decided that he would be unable to approve the
installation based on the international electrical standards. The contractor and Port looked at
other options and concluded that obtaining a third-party inspection would be the best way to get
the solar panels accepted by L&I. Third-party inspection and certification took several months
and then scheduling the state inspector for a final inspection took another month. The electrical
permit was approved on November 18, 2011, completing the final work on the project.
FINANCIAL ANALYSIS: 
The funds to pay for this change order are part of the project construction contingency funds that
were included in previously approved authorizations. No additional project funds are being
requested as a result of this change order.
