I64 Capacity Improvements Segment I

In March 2015, the Virginia Department of Transportation awarded Shirley
Contracting Company LLC, (Shirley) the Interstate 64 Capacity Improvements –
Segment I Design-Build contract. The project entailed the median widening of
approximately 5.2 miles of I-64 in Newport News, VA; adding a new travel lane and full
width shoulder in each direction on the interstate; replacement or widening of six
bridges, including two bridges over CSXT Rail; and construction of nearly 2.5 miles of
noise barrier wall.

Utilizing our experiences working on similar interstate facilities, the Design
Team developed an innovative Temporary Traffic Control (TTC) approach that
allowed commencement of construction activities within six months of NTP by
creating an Advanced TTC Plan Set. This strategy allowed for shoulder strengthening
and median clearing within existing right-of-way to start while final roadway and
bridge design elements were being completed. The Environmental Team worked
closely with the permitting agencies to avoid work in jurisdictional areas while the
final Joint Permit Application and mitigation measures were finalized.

Although the RFP allowed for the widening and rehabilitation of the existing bridges
over Industrial Park Drive and CSX Railroad, our Team developed plans which provided
two new 2-span bridges in lieu of widening and repair of the existing 3-span bridges,
resulting in shorter structures which will require less maintenance by VDOT.

Additional project elements included; widening and repairs of 4 existing bridges;
extensive maintenance of traffi c operations for over 100,000 VPD; TMS, DMS, CCTV and
overhead signage/installation; installation of 7 bio-retention and constructed wetland
SWM facilities; utility relocation/installation; installation of over 210,000 S.F. of Noise
Barrier Wall; and, installation of over 15,000 LF of storm sewer including trenchless

As the Design-Builder and Lead Contractor, Shirley was responsible for management
and oversight of the entire Project, including design and engineering, environmental
permitting, utility relocations and overall Project administration and construction
management, including QA/QC. All construction work was performed on a heavily
traveled roadway and all lane restrictions were coordinated by Shirley with VDOT to allow
for public notifications of impacts to traffic. Shirley was responsible for creating and
monitoring the schedule throughout design and construction.

The Project received the Design-Build Institute of America’s National and MidAtlantic Region Award of Merit recognizing the high quality and adherence to
the Design-Build Project Delivery standards.
