Project Experience Summaries: Government

Scope of work:
DUC was contracted by a nationwide engineering firm to design, engineer, permit, and construct a communications system for the US Army Corps of Engineers. DUC engineered the project from Maryland to inside the District of Columbia. DUC obtained permits for both the Maryland portion of the work as well as the portion in the District of Columbia. DUC provided project management for the entire build as well as procuring all materials for the project. The turnkey project was delivered
on-schedule to the Army.

Scope of work:
Through a long-term, continued relationship, the client awarded DUC a communication and power conduit installation project on Langley Air Force Base.
As the expanse of DUC's successful military projects has grown, DUC has gained significant recognition for completing sensitive projects in secured government environments. In this particular scope-of-work, DUC trenched and placed a concrete encased duct bank with multiple manholes. A challenging portion of the project specified use of a 30" auger drill with steel casing along an active runway. Additionally, the project required excessive depth for placement of the duct bank. Throughout the deeper excavation, DUC had to maintain continuous de-watering efforts when placing manholes and duct bank due to the high water table.

Scope of work:
DUC engineered, permitted, and installed the OSP and ISP for a unspecified government agency. DUC directional drilled the route to tie the secured facility into an existing MFN conduit and then excavated for two building entrances. The location of the building penetrations required a tunneling operation under the building foundation for the core drilling into building. DUC placed all EMT, inner-duct, and pull boxes along route to inside the building to reach the client's secured demarcation. The completion of the project consisted of pulling the cable from the existing MFN hand-hole as well as new hand-hole that was over-set on existing facilities into the customer's equipment room inside of building. Restoration included asphalt, concrete, and landscaping.

Scope of work:
As the preferred contractor for Washington Metro Area Transit Authority's (WMATA) passenger rail system, DUC was contracted by a world-leading telecommunications provider for the installation of fiber optic cable within WMATA's tunnel system. DUC designed, engineered, and installed fiber optic cable for both the client and WMATA in the tunnels. The work was performed only during a three-hour limited work window from 1:30 AM to 4:30 AM. DUC maintains excellent communication with the Transit Authority's telecommunications personnel, and as a result, was able to utilize this limited daily window of production to coordinate and deliver the project within budget and on-schedule. Cable was installed with clips to the tunnel walls and pulled through an existing manhole system as well as the passenger stations' plenary areas. DUC has the most experience out of any other contractor performing work within the WMATA system with over 70 miles completed for various carriers to date. DUC is also certified with the CSX and Amtrak systems for rail safety and cabling installation specifications and tolerances.

Scope of work:
One of the pioneering companies in the "communications by light" fiber optic throughput industry awarded DUC a communication lateral into 2000 Pennsylvania Avenue, Washington, DC, just a few blocks from the White House. The construction project entailed an open cut approximately 320' along "I" Street for placement of (2) 4" conduits. The sub-grade penetrations required DUC to X-ray and core drill the building foundation. DUC then pulled fiber into building for termination to our client's customer. DUC also provided and placed a 4'X6'X4' manhole and tied into an existing manhole. DUC served as the lead to coordinate project details with all parties involved on the project. DUC was also contracted to conduct the final milling and overlaying of "I" Street as well as the intersection of 21st and "I" Street. All work was completed at night and the project was delivered ahead of schedule.
