Project Details:

With the purchase of a new drone for the CDR Maguire Pennsylvania office, the company provided inspection services for the removal of a bridge structure that carried Pennsylvania State Road 1022 over the Monongahela River and the CSX, Norfolk Southern, and Donora Southern Railroads.

The PennDOT District 12-0 demolition contract totaled $2.6 million.



Project Details:

CDR Maguire provided value-engineering services for the replacement of the Barton Corner Bridge in Rhode Island, earning the design-build contractor the maximum incentive bonus of over $700,000.

The bridge carrying I-95 over Route 2 was rolled into with accelerated bridge construction (ABC) techniques in two, 45-minute sessions when the twin, 900,000-pound superstructures were rolled into place using Self-Propelled Modular Transporters (SPMTs). By rolling the bridge into place, Rhode Island DOT avoided inconveniencing the riding public for months or even years.

CDR Maguire assisted D’Ambra Construction with value-engineering proposals, environmental submittals, temporary structures, computer analysis of the superstructure during the move, and ongoing assistance as the innovative proposal went through the approval process. Thanks to our expertise and experience on other ABC projects, as well as a contractor willing to implement new innovation, the bridge took nine months to build off-site and only 90 minutes to move into place.


Project Details:

CDR Maguire was selected to provide construction management services on the new $550 million expansion of the Pennsylvania Turnpike.

This initiate includes construction of a 13-mile, four-lane, limited-access highway that will connect I-79 to the west with SR 22 and the existing Turnpike Findley Connector to the East. The majority of the construction will take place over a three-year period between 2016 and 2019.

CDR Maguire’s duties include the provision of a resident engineer for each of the construction sections to manage the project, supervise the independent inspection firms, and to provide quality assurance for the projects. In addition, CDR Maguire will provide constructability reviews, reviews of the value engineering proposals from the contractors, as well as claims review and mitigation services. CDR Maguire’s contract value for all services is $116.5 million.

Project Details:

CDR Maguire is the lead consultant and program manager for this nationally-recognized, award-winning project. The unique approach to the project included constructing the IWAY Bridge offsite and floating it into place.

The widest and first three-arch bridge in the United States, it is also the first in the world with a skew angle.

CDR Maguire engaged in all aspects of the project including road and bridge design, permitting, right-of-way procurement, geotechnical and marine engineering, and directing the design activities of 12 subconsultants.


Project Details:

CDR Maguire provided construction cost estimates and scheduling services for the $4 billion La Guardia Airport Redevelopment Program.

This Port Authority of New York and New Jersey program included demolishing the existing Central Terminal Building and parking garage and replacing them with a new terminal building and two new garages. A critical element of the project also involved the construction of a new roadway circulation system.

CDR Maguire’s unique approach allowed for the expedited individual analysis of 34 construction elements, which focused on the impact to traffic, constructability, quantity and estimates, and overall schedule – all within the budget and deadlines set by the Port Authority. Based on the study’s findings and conclusions, recommendations were identified for each of the construction elements, and the CDR team was asked to join a special task with the Port Authority’s Engineering Department to look further into the identified issues.


Project Details:

CDR Maguire provided award-winning construction inspection and management services for PennDOT District 11-0 for the 31st Street Bridge and SR 28 from Troy Hill Road to the city limits in City of Pittsburgh project (SR 0028, SECTION A09). The project received the following awards:

  • 2014 Transportation Project of the Year Award from the Engineering Society of Western Pennsylvania
  • 2014 Outstanding Engineering Achievement Award from the Pennsylvania Society of Professional Engineers, Pittsburgh Chapter
  • 2014 Civil Engineering Achievement Award from the Pittsburgh Chapter of the American Society of Civil Engineers

Key elements of this project included 1.2 miles of roadway reconstruction, 2,456 feet of new wall construction, replacement of 515 feet of the 31st Street Bridge, one new abutment with tieback anchors, one pier with a caisson foundation, and the remainder on four rebuilt pier caps.

CDR Maguire is currently providing construction inspection and documentation services, construction management services including web-based document control, environmental monitoring, claims support, engineering support, and schedule monitoring. CDR Maguire was instrumental in the constructability and schedule reviews associated with the rephasing of this complex structure and roadway project, revising sequencing that reduced traffic control phases from six down to four.


Project Details

As part of the new McDaniel Drive Extension on the University of New Hampshire Campus, CDR Maguire designed a new structure under the existing B&M Railroad tracks (Guilford Rail), which are the mainline tracks connecting Boston with Portland, Maine.

The company performed a number of studies to determine the best construction methods and materials to maintain rail service.

Architectural features were important for this project because of its location on campus.

CDR Maguire was engaged by MassDOT to provide project design review and construction oversight of the work performed by the design-build entity using Accelerated Bridge Construction (ABC) methods on its second “Heavylift” construction bridge project.

As part of the MassDOT Accelerated Bridge Program, the bridge beam will be fabricated and supported on temporary tower with deck concrete placed offsite, then Self-propelled motorized transporters (SPMTs) will be used to move the bridge to its location. 72 hour traffic shut down will only be allowed for the existing bridge demo and new bridge erection.

CDR Maguire was responsible for review of all design submissions and construction project management for the bridge and highway work; acceptance of the final construction contract package; review of the Design-Build team’s QA/QC control program and submissions; maintaining a record of submittals; and providing part-time on-site inspection services.
