Contract Type: Design-Build
Contract Amount: $54.4 million
Location: Indian River County, Florida
Client: FDOT District Four
Design Partner: Stantec

The project includes the addition of one lane in each direction of I-95 throughout the project corridor, milling and resurfacing of the existing mainline lanes, reconstruction of the SR 60 interchange, replacement of the mainline bridges at 90th Avenue, 4th Street and SR 60, construction of sound walls and ITS modifications. The de Moya Design-Build Team provided the best value and received the highest technical score on this $54.4 million project.

Project Features:

The de Moya Design-Build team produced several innovative solutions including;

  • Master Plan alignments for 4th Street/ 90th Avenue affording Indian River County to build the future corridor expansions at a reasonable cost. The realignment at 90th Avenue allows for the reduction of the bridge length and the skew presented in the RFP Concept Plans.
  • Modified mainline median widths through the reconstruction segments of the mainline at 4th Street, 90th Avenue and SR 60 to reduce/ eliminate throw-away work. The modified alignment simplified construction and Maintenance of Traffic (MOT).
  • Re-designed ramps at SR 60 to facilitate construction and reduce MOT phases, embankment, walls, and construction duration without requiring any ramp closures.
  • Developed cross slope correction algorithmic program with Geopak that optimized use of overbuild and readily identified trouble areas along the travel lanes and shoulders.
  • The de Moya Team was able to cut the proposed contract time nearly in half, reducing the project duration from 1,600 days to 850 days.


Contract Type: Conventional Bid
Contract Amount: $71 million
Location: Miami-Dade County, Florida
Client: FDOT District Six
Completed: 2007

This $71 million project included the construction of the SR 826 Interchanges at NW 74th Street and at US 27 in Miami-Dade County.  The project provided 11 bridges including four structural steel bridges, five pre-stressed concrete girder bridges and two cast-in-place concrete bridges.  The de Moya Group submitted six Value Engineering Change Proposals that were approved by the FDOT and provided substantial project savings.

Project Features:

  • Extensive erosion control and environmental protections for the canal crossings and the adjacent canal for the entire construction duration.
  • Major construction activities included bridge work, pile and bulkhead construction, embankment, paving, lighting, signalization, and signing.
  • The de Moya Group’s project personnel were extremely proficient in resolving constructability, right-of-way, and utility conflicts throughout the duration of the work.


Contract Type: Conventianal Bid
Contract Amount: $28 million
Location: Palm Beach County, Florida
Client: FDOT District Four
Completed: 2001 

The project provided for the reconstruction of the I-95/ Okeechobee Boulevard interchange from south of Australian Boulevard to Congress Avenue and replaced the outdated and dysfunctional existing clover-leaf interchange design with a new double curved box girder flyover bridge (approximately 900 LF).

Work also included providing a new eight-laned concrete girder bridge over I-95, reconstruction of all on and off ramps, new signalized intersections on Okeechobee Boulevard both east and west of I-95 at the on/ off-ramp terminals which included triple left turn movements, the addition of auxiliary and general purpose lanes on I-95 in each direction with two-lane on/ off ramps, and milling and resurfacing of existing I-95.  

Project Features:

  • Ramp bridge on a sharp 490-foot radius curve carrying traffic from westbound Okeechobee Boulevard over I-95 and Okeechobee Boulevard to southbound I-95.
  • Removal of existing loop ramps in the northeast, northwest and southwest quadrants and reconstructing the loop ramp in the southeast quadrant.
  • Substructure consisting of end bents and hammerhead single column piers on pre-stressed concrete piling.
  • Sound walls, decorative MSE walls, decorative precast gravity walls, jack and bores, and extensive landscaping.
  • Complex MOT schemes were required to ensure traffic was afforded access to Okeechobee Boulevard and I-95 throughout the 18-month accelerated construction schedule.
  • dMG Value Engineering concept to provide full superstructure replacement in lieu of hydrodemolition  and bridge jacking.

I-75 (16 miles) wins 2011 FTBA Best in Construction Award (Alternative Contracting)

On August 5, 2011, the de Moya Group was presented with the Florida Transportation Builders Association Best in Construction Award by FDOT State Secretary of Transportation Ananth Prasad, P.E.

This $18 million, 16-mile resurfacing project in Broward County along I-75 (Alligator Alley) from MP 35.000 to a point west of US 27 (MP 18.870) included pavement restoration & rehabilitation, new signing & pavement markings, landscaping, expansion joint replacement on 22 bridges and upgrade of all existing call boxes within the project limits.

Even in this remote location, Asphalt Group, Inc. (a wholly owned subsidiary of the de Moya Group) was able to place 3.8 miles/ over 1,600 tons of asphalt in a single day and averaged 2 ½ miles and 1,400 tons of asphalt per day. This production rate was maintained throughout the thirty-two miles of asphalt placed (sixteen miles in each direction).

In addition, the maintenance of traffic during the paving operations was executed without incident, with limited disruption to the traveling public and with no construction related accidents.

The de Moya Group proposed changing the original designed inside shoulder widening (6 ft) pavement design from Optional Base Group-4 (4”) Asphalt –Type B-12.5 only and one inch (1”) SP structural course Traffic Level-C to Optional Base Group-5 (7”) limerock base and one and half inch (1.5”) SP structural course Traffic Level-C at no additional cost to the FDOT. This change eliminated multiple lifts of asphalt base and allowed for increased production with the use of limerock base. In addition, this modification created a safer workzone by reducing drop-off conditions. The FDOT realized a 50 calendar day credit for implementation of this proposal in addition to receiving an upgrade to the original base group design.

Thanks to Grant Cool, John Allen and Walter Brewer for making this project a success!
