Project Experience Summaries: Design / Engineering
DUC's engineering project experience has included fiber
routed in all environments (aerial, underground, attached conduit, etc.),
and all types of plant including water, power, CATV, and bridge/building
attachments. Additionally, engineering and CAD work has provided our government
clients with precise designs for the most stringent security standards.
DUC is able to engineer projects with the lowest resulting construction
costs. As a result of DUC's firsthand experience with the construction
and project management phases, DUC is able to engineer projects so that
material and labor costs are held to a minimum without sacrificing quality.
DUC provides outside and inside plant design services for twisted pair,
coaxial, fiber optic, and copper cable networks. Additionally, DUC has
also established a reputation for engineering and construction within
the security and surveillance fields and interconnect of CCD cameras,
pop-up gates, and other associated ground-based sensors.

Construction, Cable Survey & Mapping
Scope
of work:
Down
Under Construction (DUC) was contracted to over-set manholes and
survey all associated plant for a leading national networking services
provider on their existing system throughout the District of Columbia.
Work consisted of excavating the existing fiber optic cabling system
and over-setting a larger, secured shelter style manhole over the
client's facilities. In the second phase of the project, the duct
was sliced open and the existing cable was racked to the new manhole
wall. All conduits were then surveyed and routes mapped from the
new manhole to existing manholes. All ducts were identified, and
tagged by carrier within the system for future repair or maintenance.
DUC's final phase of the project was to complete restoration for
each manhole to the District of Columbia's specifications.

Design/Engineering, Material Management
Permitting, Project Management
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.

Design/Engineering, Permitting, Project Management
Splicing, Hourly Labor Placement
Scope of work:
DUC was contracted to excavate and install several large concrete
encased power duct banks. The military base environment required
strict adherence to security rules and guidelines including a pre-screening
of all DUC employees. The installation of multiple ducts in concrete
encased duct banks with power manholes specified unusually deep
placement in the ground. As a result of this depth, de-watering
the excavation sites due to high water table was mandatory. DUC
also provides hourly operator services to the client for other projects
that necessitate quick responses with either skilled or unskilled
labor and equipment.
Services:
Construction, Engineering, Permitting
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.
Services:
Construction, Engineering, Permitting, Project Management
Scope of work:
This high visibility project involved four sub-grade entrances with
directional boring, hand trenching, placing hand-holes, and pulling
fiber. Both scopes of work required detailed planning and coordination
with the client to determine changes in building entrances and running
precise multiple routes to ensure secure circuits. Landscape restoration
was extensive, and required a full re-planting of mature trees and
shrubs.

Construction, Design / Engineering, Project Management
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.
