Equipment and techniques
38、 proposed for use in the work shall not be used until they have been demonstrated and approved. Materials and equipment, which have not been approved for use in the work, shall not be stored or brought on to Government property. Provide equipment, materials, and labor to demonstrate materials, equip
39、ment, and techniques proposed for use in the work. Perform the demonstrations at the site, at a time and location as directed.
