Worked with the client and with subcontractors on feasible retrofit options for the Pattullo Bridge. This

bridge in Vancouver, British Columbia has multiple design and construction constraints including: severe in-

situ deterioration, in-water pier work windows and numerous third-party issues. Work was performed for

the BC Ministry of Transportation and Infrastructure and for TransLink. 2014-2015

Honolulu Authority for Rapid Transportation (HART), Honolulu, HI, USA

Independent Design Check Lead. Independent superstructure post-tensioning check for elevated precast

segmental span-by-span single-box light rail guideway spans for the upcoming Honolulu Rail Transit Line.

Checks included: longitudinal and transverse post-tensioning, dapped-end E/J pier diaphragm segments,

deviator segments, and single box wing-tip analysis. 2014-2015

St. Croix River Crossing, Minneapolis, MN, USA

Senior Technical Advisor and Independent Design Check Lead. This 5100-ft long signature extradosed

bridge consists of 3360 feet of main bridge with 18-ft deep precast concrete box girder superstructure

segments and up to 234-ft tall concrete towers. The extradosed main bridge has four main spans of 600

feet and side spans of 340 feet. Scott served as a Senior Technical Advisor for the extradosed main span

and as the Independent Design Check Lead for the approach bridges on the project. The six approach

bridge structures included three precast segmental and three cast-in-place bridges, with variable span

lengths, a 290-ft maximum span, variable depths, horizontal curves and flared width sections. He

supervised a team of engineers in multiple offices. 2012-2014

St. Croix Extradosed Bridge – Minneapolis, MN

Hudson Hope Bridge, Hudson’s Hope, BC, Canada

Senior Technical Advisor. As part of the Enhanced Bridge Inspection, Evaluation, and Design Services As-

and-When BC Northern Region contract, the Hudson Hope Bridge is a two-lane highway suspension bridge

built in 1964 with a main span of 680 feet. Scott performed a field inspection and followed with a

conceptual design of a replacement of the bridge concrete segmental box external post-tensioning system.

The conceptual retrofit design would have allowed re-use of the existing embedded anchorage assemblies

and replaced the single 1-1/8" bridge strand (typically no longer used for long term bridge post-tensioning)

with modern 7-wire post-tensioning strand. 2013-2014

Canada National Parks Snow Shed, Canada. Senior Structural Engineer. Structural review and evaluation of

rehabilitation and/or new design needs for snow sheds built in the 1960s in the Canadian National Parks,

located in the British Columbia Rocky Mountains. Scott led the effort to assess existing snow shed concrete

structural capacity by performing load ratings, interpreting previous inspection reports and recommending

repair and/or replacement options to the B.C. Ministry of Transportation. 2012-2013

for replacement of the longest floating bridge in the United States, SR 520, connecting Seattle, WA to

Bellevue, WA. Scott served as Buckland & Taylor’s deputy project manager for the effort and developed a

pre-bid, conformed design criteria for the project integrating required AASHTO, WSDOT and Sound Transit

Light Rail bridge design codes. 2011-2012

Evergreen Millennium Line Extension, Vancouver, BC, Canada

RFP Structural Design Task Lead. As part of the Evergreen Advanced Rapid Transit (ART) extension,

scheduled to be completed in 2016, Dr. Phelan led RFP conceptual structural design planning activities for

the elevated transit sections. Working with the B.C. Ministry of Transportation bridge engineers and with

other project engineers, Dr. Phelan assisted the Ministry as they implemented a new three-level seismic

design criteria for the Evergreen line extension. From an initial design concept, Dr. Phelan eliminated all

major straddle bents along primary publicly-viewed portions of the alignment as public surveys had shown

little satisfaction for this type of structural solution in past Vancouver ART projects. The rapid transit line

extension is 6.8 mile (11 km) in total length, with an expected construction cost of $1.4 billion CAD. The RFP

was developed considering state-of-the-art elevated ART design schemes including balanced cantilever,

simple spans using an overhead launching gantry, three- and four-span continuous units, dual- and single-

track box sections, and multi-span steel units. Design constraints considered included traffic management,

high voltage overhead transmission lines and integration with existing ART stations. 2009-2011

I-90 Homer Hadley Floating Bridge Light Rail Transit, Seattle, WA, USA

Senior Technologist. Consultant for Sound Transit's preliminary engineering proposed East Link light rail

project to expand light rail service from downtown Seattle to the Eastside, across Lake Washington. As part

of a special Sound Transit I-90 Homer Hadley floating bridge structural solution team, Dr. Phelan assisted

with development of a conceptual solution for attaching two new light rail tracks to the existing I-90

floating bridge. The conceptual track attachment system solution was constrained significantly by

requirements for a minimum number of new penetrations into the existing bridge deck and for minimal

additional weight to maintain current overall floating bridge pontoon freeboard. 2010-2011

Puyallup River Bridge, Tacoma GEC HOV Program, Tacoma, WA, USA

Senior Structural Engineer. Completed preliminary plans and assisted with the type, size and location

(TS&L) study for replacing the existing 2,200-foot-long I-5 crossing over the Puyallup River, leading the

structural superstructure portion of the design. Several innovative structural schemes were evaluated

including concrete segmental, spliced-girders and variable depth girders. The technically advanced scheme

selected represented the least risk in construction cost and delays to the owner and to the railroads.

Extensive coordination and meetings with Burlington Northern Santa Fe (BNSF), Tacoma Rail, and Union

Pacific railroads was required. 2007-2009
