2.02 ACCESSORIES
A. Provide factory made waterstop fabrications for all changes of direction, intersections, and transitions leaving only straight butt joint splices for the field.
B. Provide grommets, pre-punched holes, or hog rings (installed by others) spaced at 12 inches on center along length of waterstop.
C. Provide Teflon coated thermostatically controlled waterstop welding irons for field butt splices.
PART 3 EXECUTION 3.01 INSTALLATION
A. Field butt splices shall be heat fused welded using a Teflon coated thermostatically controlled waterstop welding iron at approximately 380 degrees F. Follow approved waterstop manufacturer recommendations. Lapping of waterstop, use of adhesives, or solvents shall not be allowed.
B. Center waterstop in joint and secure waterstop in correct position using grommets, pre-punched holes, or hog rings (installed by others) spaced at 12 inches on center along the length of the waterstop and wire tie to adjacent reinforcing steel.
Waterstops 03150-3
3.02 FIELD QUALITY CONTROL
A. Waterstop splicing defects which are unacceptable include, but are not limited to the following:
1. Tensile strength less than 80 percent of parent section.
2. Misalignment of centerbulb greater than 1/16 inch.
3. Bond failure at joint deeper than 1/16 inch or 15 percent of material thickness.
4. Misalignment that reduces waterstop cross section more than 15 percent.
5. Visible porosity in the weld.
6. Bubbles or inadequate bonding.
7. Visible signs of splice separation when cooled splice is bent by hand at a sharp angle.
8. Charred or burnt material.
END OF SECTION 03150
Prefabricated Building Building Design Specifications:
• Interior walls and ceiling: 10 gauge steel • Exterior walls and roof: 26 gauge PBR panel • Self-Framing Steel Construction • Structural Steel Skid Frame with ¼” floorplate • Undercoating • Roof Slope: Single Slope, ½” per foot • Paint: PSX 700 2 part epoxy • Fire and Weather Resistant Construction
Mechanical:
• Structural PE Stamp: Yes • Design Codes: IBC and NEC. • Structural Welding D1.1/D1.3 • Bolt on lifting eyes bottom frame lift • L/960 Deflection during lifting
Building General Construction Details: Buildings are one of a kind, custom built, walk-in, weather resistant, non-combustible and fully engineered enclosures that include the following standard features: Construction, based on the 2012 IBC, AISC Steel Construction Manual, 13th Edition, and Detailing for Steel Construction, 2nd Edition, consists of a structural steel channel base frame, 1/4” steel floor plate, 10 gauge interior wall panels, ceiling panels and ceiling joists. Steel member joints and seams are connected by fully sealed continuous welds. Building roof is single slope at ½” per foot. Slope direction is based on door location, exterior features and site conditions. Heavy duty removable lifting eyes located at skid (quantity as required per engineering design) will be provided for picking and placing the building with a crane. *Quoted skid deflection is L/240. Insulation: Walls (R-23) and ceiling (R-23) cavities are insulated with custom cut ROXUL ComfortBatt ™ stone wool insulations made from basalt rock and slag. This combination results in a non-combustible product with a melting point of approximately 2150°F (1177°C), which gives it excellent fire resistance properties. ROXUL stone wool is a water repellent yet vapor permeable material. This material has a Flame Spread of 0. The building skid will be insulated with spray applied rigid polyurethane foam in thickness required to achieve an approximate thermal resistance of (R-30). In addition, the building skid will be undercoated with Amercoat 240 Universal Amine Epoxy Coating from PPG to an approximate thickness of 6mils dry. Standard Painting Process: All steel interior surfaces and exposed exterior surfaces are thoroughly cleaned with a phosphatizing acid wash prior to painting. Our high quality Engineered Siloxane Epoxy paint system consists of a coat of PPG’s “Amerlock” primer and PPG’s “PSX-700” coat of paint in the Owner’s choice of our standard colors. PSX 700 is a patented composition that embodies the properties of both high performance epoxy and polyurethane in one coat. This general purpose coating offers “breakthrough” weather resistance and corrosion control. It provides protection and excellent, long lasting appearance in one application, exceeding the gloss and appearance retention of the best polyurethane.
Exterior Siding: Exterior walls and roof are covered by preformed 26 gauge PBR panels. The base metal is manufactured from a high strength Galvalume® and coated with Signature® 200 thermoset polyester resin in the owner’s choice of standard colors per attached. Signature® 200 carries a 25-year limited warranty. *Please Note: Additional fees will apply for non-standard siding and/or paint colors.
