Site work and paving for a transportation facility in Saint Paul, Minnesota. Completed plans call for site work for a transportation facility; and for paving for a transportation facility.

Medium voltage substation replacement for normal and emergency power, ductbank construction, apron pavement work, excavation, asbestos abatement, concrete, masonry, steel, waterproofing, curtain wall, doors, gypsum, painting, mechanical exhaust/chilled water cooling replacement, storm/sanitary line rerouting, switchgear/ATS installation, and telecommunication network connections. This project will provide the electrical equipment for medium voltage substations for both normal and emergency power, for which an earlier project provided the building shell space on Concourse C. In addition, this project will connect these rooms to an existing electrical room by Gate C1 by building ductbank on the apron, and will provide emergency power feeders back from the Generator building to the new C concourse emergency substation. The electrical room near Gate C1 will be rebuilt for this effort. Civil work will include apron pavement removal and replacement, excavation, duct bank and manhole installation, and backfilling. Construction will include asbestos abatement, concrete work, masonry, steel framing and grating, waterproofing, curtain wall , metal soffit panel installation , doors, gypsum board work, and painting. Mechanical work will include replacement of an existing exhaust system in an electrical room with a new chilled water cooling unit, and rerouting of existing return air pathways back to air handling unit C02. To accommodate the electrical work, two unit heaters will be replaced and underground storm and sanitary lines will be rerouted. Electrical work will include the removal of the existing medium voltage substation in the electrical room by the C1 gate area, along with existing switchboards. The existing electrical substation room will then be converted into an electrical room with distribution switchboards. The medium voltage substations for both normal and emergency power for Concourse C will be provided from the newly built-out space from the previous project. This project will be responsible for the procurement, installation and commissioning of medium voltage substation switchgear, automatic transfer switches, distribution boards, and associated equipment in the new built-out electrical substation rooms. Lastly, electrical work will also include power feeds from the new normal and emergency substation rooms to the electrical room by C1 via the duct bank per this project. Telecommunication work will include new network connections for the new IP controllers and monitoring of new electrical substation equipment.
