The Contractor shall install all water fittings, hoses and electrical connections from the portable chiller to the building. The work to be accomplished under this delivery order requires the contractor to furnish all equipment, materials, transportation, administration, supervision, and everything else necessary to provide the temporary chiller for a period of six months.
