Bid is subject to the RFQ - Standard Terms and Conditions. By submittal of a bid, bidder certifies its agreement to these terms and conditions, which cannot be waived. Tennessee Tech is seeking bids from a qualified company to provide and install pavers for a special project. Square footage for installation is approximately 3,500 square feet; Bidder is responsible for getting own measurements. Please contact Scot McCrary at 931.260.2945 or smccrary@tntech.edu to set-up appointment. Completion date of project shall be 8-weeks from start date (preferably by March 1, 2023). Pavers to be furnished and installed o Belgard Aqua Bric, Ardennes grey - 5" x 10" x 3 1/8 Base Course Preparation o A suitable base must be prepared as detailed in other sections of the project specifications. o The base course shall be shaped to grade and cross section with an allowable tolerance of 1.4" (5mm). o The compacted base thickness in as follows: Patios, sidewalk, pool decks, and other designated areas for pedestrian walkways shall be at least 4" (100mm) on well drained soils. We shall require a layer of Geotextile fabric. Construction of the Sand Laying Course (drawings below) o The finished base course shall be approved before the placement of the sand-laying course. o The uncompacted sand-laying course shall be spread evenly over the area to be paved and then screened to a level that will produce 1" (25mm) thickness when the paving stones have been placed. Normally, it is good practice to have final elevation of paving stones slightly higher than adjacent curb, gutter, other paving, to allow for any minor settling that may occur within the base. Maximum bedding sand thickness shall not exceed 1 1/2 ". o Once screened and leveled to the desired elevation, this and laying course shall not be disturbed in any way. Laying of Concrete Paving Stones: 1. The paving stones shall be laid in Herringbone Design pattern (shown on the drawing below). 2. The paving stones shall be laid in such a manner that the desired pattern in maintained and the joints between the stones are as tight as possible. Joints between stones shall not exceed 1/8" (3mm). 3. String lines should be used to hold all pattern lines true. 4. All work more than 6 ft. (2m) of the laying face shall be left fully compacted and sand-filled joints at the end of each day or compacted upon acceptance of the work. 5. Cover the laying face or any incomplete areas with plastic sheets overnight if not closed with cut and compacted pavers with joint sand to prevent exposed bedding sand from becoming saturated from rainfall. o The gaps at the ends of the paver surface be filled with standard edge stone or with stones cut to fit. Cutting shall be accomplished to leave clean edge to the traffic surface using a masonry saw. Whenever possible, no cuts should result with a paver less than 1/3 of original dimension. o Paving stones shall be vibrated into the sand-laying course using a vibrator capable of 3,000 to 5,000 pounds of compaction force with the surface clean and joints open. At least two passes with the vibrator should be made across the surface. o After vibration, polymeric masonry type sand at least 30% of the 1/8" (3mm) particles shall be spread over the paving stones surface, allowed to dry, and vibrated into joints with additional vibrator passes and brushing so as to completely fill joints. o Surplus materials shall then be swept from the surface or left on surface during construction time in ensure complete filling of joints during initial use. This sand also may provide surface protection from construction debris. o Do not vibrate within three feet of unrestrained edge. All work within three feet of the laying face must be fully compacted edge of the laying face and sand with a waterproof coverage. Sweep off excess sand when the job is complete o Upon completion of work covered in the Section, the Contractor shall cleanup all work areas by removing all debris, surplus material and equipment from the site. o Cleaning: all dirt, grime, and fresh oil and grease shall be removed from the concrete paver surface prior to job being complete. Spray or brush cleaner onto paver surface and then rinse away with clean, potable water. Flammable ingredients or acids are not to be used. Use Addiment Dirt and Grim Remover, or Addiment Efflorescence Remover and General Cleaner, or approved equal. o Sealers: No sealer shall be applied until after a thorough cleaning of paver surface. Sealer shall be sprayed or rolled onto clean, dry surface, using Addiment Paver Seal - WB, or approved equal. C. Cast Stone Cast stone shall be constructed per manufacturer's recommendations. Drawings and recommendations shall be submitted for review prior to beginning of construction. Joints shall be 1/2 ", slightly concave, color to match cast stone. Base rails and bridge shall be drilled and dowelled and grouted securely. o Metal forms to be used to hold pavers around all landscaping edges.
