Level 3 (Formally Global Crossing) - St. Croix, USVI
Since 2003 Encon has been providing MEP engineering and construction management services for Global Crossing’s St. Croix facilities in the US Virgin Islands. The site has two buildings; the first is the South American Crossing (SAC) building, approximately 80,000 square feet; the second is the Mid Atlantic Crossing (MAC) building, approximately 40,000 square feet. Both SAC and MAC are terrestrial cable landing stations for Globing Crossing’s worldwide sub-sea fiber network.
Encon provided engineering and construction management services for the replacement of all mechanical systems in the SAC building. The building is located approximately 250 feet from the ocean, a harsh operating environment for exterior mechanical and electrical equipment.
Exterior mechanical equipment life cycles had been reduced to less than 5 years because of the environment and the use of excessively long refrigerant piping runs beyond good engineering design practice and published installation guidelines.
Windstream Hosted - Solutions, Charlotte, N.C.
Encon, as the prime design professional, provided MEP, fire protection, structural, and architectural design services for this design-build project. The project required the renovation of a 10,000 square foot data center to provide for 150 watts per square foot of technical load.
The new data center has a 36 inch raised floor utilizing down-flow cooling air handing units. Two nominal 350 ton air cooled chillers located on the roof with supporting pumps and controls (in a 2N configuration) deliver chilled water to the air handling units.
Electrical design scope included a 2500 kVA utility transformer provided by the building owner to serve a 3000 amp main service switchboard.
Normal power for the critical plant and the mechanical systems distribution are served by the main service switchboard. The critical plant consists of four 550 kVA/495 kW static UPS modules paralleled in a 2N arrangement. The UPS outputs are connected to UPS paralleling switchboards with an integral static switch and maintenance bypass. The distribution to the data center floor branch circuits is via 10-300 kVA power distribution units.
Century Link (Qwest Comunications) - Newark, NJ
Encon, the prime design professional provided construction management, MEP and fire protection for this design-build project. The project scope of work included the installation of a nominal 300 ton custom glycol based dry cooler system to serve approximately 30,000 sf of technical space.
Due to severe space limitations, the new dry cooler system was built in a restricted area with limited floor space and slab to slab clearance. The key elements of the custom dry coolers are 28 lead/lag glycol coil assemblies and 33 plug type fans with integral variable speed drives. The use of fan variable speed drives and glycol pump variable speed drives minimized energy consumption. Further the acoustical impact on the surrounding neighborhood was significantly reduced from the existing traditional dry cooler system that was removed.
Using creative construction phasing, all project work was completed while maintaining complete operations with no service outages. Final commissioning revealed that the installed custom dry cooler system exceeded expected total heat rejection capacity. The end user was provided with greater site operating flexibility, reduced future infrastructure expansion, thereby reducing future capital expenditures.
