Temporary Heat and Ventilation
As necessary, provide temporary heat and ventilation required by construction activities, for curing or drying of completed installations or protection of installed construction from adverse effects of low temperatures or high humidity. Select safe equipment that will not have a harmful effect on completed installations or elements being installed. Coordinate ventilation requirements to produce the ambient condition required and minimize consumption of energy.
Provide telephone communications at project site
Contractor's Employee Parking
Shall be limited to locations designated at the Pre-construction Conference.
TEMPORARY BARRIERS AND ENCLOSURES
Provide barriers and fencing to prevent unauthorized entry to construction areas and to protect existing facilities and adjacent properties from damage.
Provide six foot high commercial grade chain link fence around construction site as directed by OSU Project Manager; equip with vehicular and pedestrian gates with lock.
Exterior Closures: Provide temporary secured, weather-tight closures at exterior openings, to permit acceptable working conditions and protection of the Work.
Provide temporary floor to ceiling partitions (not plastic sheeting) and ceilings as required to separate work areas from OSU occupied areas, to prevent penetration of dust and moisture into OSU occupied areas, to reduce construction noise, and to prevent damage to existing materials and equipment.
