Projects

So-Deep performed internal investigation of five communications vaults. All of the vaults were physically secured and access thereto required close coordination with USAF personnel. Each vault entry was performed in accordance with 29 CFR 1910.146. Several required the pumping of large volumes of water and the mitigation of oxygen deficient atmospheres. Deliverables included detailed diagrams and digital images of the various conduit and cable configurations inside of each vault.

So-Deep has performed SUE services for the Philadelphia International Airport as a sub-consultant under a number of design contracts. So-Deep was contracted to provide Quality Level “A” information along the proposed path of Jet Fuel lines for the Fuel Farm/Hydrant Fueling System upgrade within the airport grounds. The upgrade to the fueling system would minimize or eliminate the need for fueling trucks.

The project required field work to be conducted within the airport fuel farm and on the restricted “air-side” of the property. So-Deep coordinated with their client and Airport Operations/Security to access the site. Due to airport restrictions, the “air side” operations were conducted during limited nighttime hours when airplane movement is the lightest.

Plans provided to So-Deep for test hole locations were found to have many utilities inaccurately depicted. Crew members made field adjustments to ensure the information returned met the clients overall needs. So-Deep researched and provided a specialized concrete material for the test hole patches that fulfilled the curing time and airplane load requirements.

So-Deep was contracted to provide Quality level “A” information for another airport project, the Terminal “F” Expansion. This project was on the “land” side of airport operations and concerned the exact location of Communication and Electrical duct banks in relation to the current Terminal “F” overhead walkway foundation piers.

So-Deep was selected to perform critical surveying and mapping tasks for input to the RDU Airport GIS Mapping Project. In Phase I, we utilized GPS/RTK as well as conventional surveying techniques to precisely locate approximately 225 sanitary sewer manholes. Internal control points were set for future surveying needs. Closed traverse loops were run to confirm existing control monumentation to RDU contract specifications. Differential level loops were used to confirm existing benchmarks and to establish necessary temporary benchmarks. Additional levels were run to establish rim elevations on each manhole. All survey work was referenced to the existing Airport Control Network. In Phase II, we setup a new Static GPS control network to generate additional control on the project. Approximately 355 storm sewer structures were located. A site/topographic survey was performed in one area of the airport to incorporate into the mapping process.

Subsequent to these investigations, So-Deep conducted multiple SUE investigations for the RDU Airport Authority. These ranged from Quality Level “B” investigations during the preliminary design phases of new Terminal 1, the Central Energy Plant and for the creation of accurate utility mapping in the most active portions of the airport. Quality Level “B” investigations were also conducted throughout the airport property to assist facilities maintenance personnel in resolving areas of insufficient or conflicting utility record information.

So-Deep also conducted Quality Level “C” and “D” investigations at select locations of the airport to assist in the development of the airport’s GIS database. Quality Level “A” investigations were also performed to reconcile discrepancies in the airport’s utility datum.
