A selection of our representative projects are as follows:
of Runway 12/30 Dulles International Airport
Prepared MWAA format MicroStation drawings of the field
survey of Runway 12-30, a runway reconstruction project.
Due to the high demand on Runway availability, all field
survey work was performed between 11:00 pm and 6:00 am.
Using GeoPack, cut cross-sections and profile the centerline
of the proposed alignment to quality control all of the
field survey data. Provided stake-out and location information
of geotechnical investigation being performed by subcontractor
(TLB). Provided Civil Engineer and CAD operator to work at
Prime engineer office in preparation of design drawings.
Ronald Reagan Int. Trade
Center Washington, D.C.
Provided field surveys for the design team preparing plans
for the Ronald Reagan International Trade Center, 14th &
Pennsylvania Ave. NW. The surveys included; site topography;
underground utility surveys; project property limits determined
by ‘Federal Reservation’ boundaries; building
footprint computations; building footprint stake-out for
field review and approval. Also, surveys were performed to
provide vertical heights of relevant architectural elements
of adjacent buildings, John A. Wilson District Government
Building & Interstate Commerce Commission Building.
This information allowed the design team to closely match
building fascia. Followed on surveys including the preparation
of Easement Plats for large underground utility structures
and the underground parking garage ramp.
Museum Washington, D.C.
Prepare a GIS database of an existing 26 acre private museum
dedicated to the preservation of 19th century Arts. The
data base was used for Master Planning and restoration
and upgrading of facilities and infrastructure. The project
included digitizing thirty year old base maps and inserting
updates to all facilities and infrastructure to reflect
World War II Memorial,
The Mall Washington, DC.
Cervantes & Associates, P.C. provided the Architectural
Design Firms, a current up-to-date metric unit survey of
the Memorial Site, including the layout of mock elements
of the Memorial for regulatory agency review and approval.
Upon award of construction contracts C & A was retained
to provide construction stakeout services for the major
elements of the projects. The project schedule soon dictated
that day to day layout services would be required to keep
up with construction of all of the elements of the project.
From July of 2002 through January of 2004, C & A was
on site providing construction engineering services.
From 50’ below grade to 20’ above grade from
slurry wall excavation to finish stone layout C & A
has been there.
NETC, Topo, Boundary & Utilities Surveys, Federal Emergency
The scope of this survey included establishing new permanent on-site monuments; establishing new
horizontal coordinate and vertical elevation datum’s; preparing new photogrammetric topographic surveys and location of
all surface evidence of existing underground utilities. The campus like setting of NETC is in excess of 107 acres.
Global Positioning Systems were utilized to establish NAD 83 horizontal coordinates and NGVD 88 vertical elevations.
Permanent monuments were established at various locations around the campus and are published in book form for the
continued use by staff and others working on the campus. New aerial photography was flown to capture the most current
conditions of the campus and used to develop topographic data. The final mapping was delivered in digital form at a
compilation scale of 1”=40’ with 1’ contours. The existing boundary information based on the time of acquisition of the
campus was researched, recovered in the field and included in the horizontal surveys to establish a common database.
Underground utility surveys were performed by first cataloging all of the existing underground utility contract
drawing available from the campus. A survey then followed to locate all of the appurtenant structures of the respective
utilities. All storm and sanitary sewer systems were opened and measured and cataloged as part of the survey. All other
utilities including communication, water, gas, electric and utility tunnels were compiled from field locations and
existing record drawings. Also included in the inventory were the locations of specimen trees.
The final data was submitted in digital form.
North Area Improvements II Dulles International Airport
Landside civil design projects under a Task Order Agreement.
Engineering design surveys for the connection of Rudder Road to Cargo Road. Cargo Road is extended Northerly
from existing Cargo 6, Building Phase I. Rudder Road is extended Westerly from Autopilot Road to a new intersection
with Cargo Road.
Dulles Airport Access Highway survey for westbound realignment and collector / divider lanes.
Lincoln Circle Washington, D.C.
Established horizontal and vertical control, provided topographic and underground storm and
sanitary systems in the area around the Lincoln Memorial located on the Mall in Washington, D.C. The project
required close coordination between National Park Service the controlling and maintenance, and Eastern Lands FHWA
the contracting authority
