Installation Instructions

The purpose of the patented WALL ALIGNMENT AND SCAFFOLDING SYSTEM (WASS) is to facilitate the accurate erection, alignment, concrete placement and curing of INSULATED CONCRETE FORM (ICF) WALLS. WASS is secured to ICF concrete form work with coarse thread drywall or self tapping coarse thread screws at the particular system's built-in strapping faces or the area indicated by the system's manufacturer.

WASS includes different hardware components which when assembled form a complete system. SINCE IT IS ESSENTIAL THAT THESE COMPONENTS BE CORRECTLY ASSEMBLED, READ THE FOLLOWING INSTRUCTIONS CAREFULLY. PRIOR TO USING WASS, CHECK WITH YOUR LOCAL SAFETY REGULATIONS OFFICE THAT WASS CAN BE USED IN YOUR AREA FOR YOUR PROPOSED APPLICATION(S). If you have questions regarding any aspect of WASS, contact your WASS supplier before proceeding.

USE ONLY GRADE No. 1 OR No. 2 WOOD FRAMING STUDS WITH WASS TO ELIMINATE THE POSSIBILITY OF ACCIDENTS AND/OR INJURIES DUE TO INFERIOR WOOD QUALITY. The system is designed to use wood member sizes commonly found in conventional construction. This allows the reuse of wood elsewhere in the project after WASS is taken down. WEAR WORKING GLOVES WHEN HANDLING THE WASS; SOME OF THE COMPONENTS MAY HAVE A SHARP OR ROUGH INTERIOR FINISH

Installation:

1. AS PER MANUFACTURER'S RECOMMENDATIONS and desired wall configuration, install the ICF system (block, panel or plank) to a height of approximately 5-6 feet. Then commence installation of WASS as per Figures 1 to 9. IT IS RECOMMENDED THAT WASS BE INSTALLED ON THE INSIDE OF THE FORMWORK TO PROVIDE FOR GREATER WORKING SPACE.

Figure 1

2. After the ICF system is installed to a height of 5-6 feet, FORM UPRIGHTS BY NAILING TOGETHER TWO STRAIGHT 2" x 4" STUDS WITH A MINIMUM OF THREE 31/2" SPIRAL OR COATED NAILS. PLACE UPRIGHTS EVERY 6'-0" ON CENTER (MAXIMUM) OR AS REQUIRED. See Figure 2.

3. Using a 1/2" X 1/2" router groove or 5/8" drill bit notch or drill the uprights at the required working height for a walkway platform See Figure 2 . NOTE 1: THE MAXIMUM WORKING HEIGHT FOR THE SMALL WALKWAY BRACKET MODEL (ONE SCAFFOLDING PLANK WIDE) IS NO MORE THAN 4'-0" FROM TOP OF PLATFORM TO GROUND OR FLOOR. CHECK WITH YOUR LOCAL SAFETY REGULATION OFFICE FOR THE HEIGHT, PLATFORM, WIDTH, GUARD RAIL, MID-RAIL AND TOE BOARD REQUIREMENTS THAT APPLY TO YOUR PROJECT(S).

Figure 2

4. Insert the WALKWAY LINK hardware in the 1/2" X 1/2"router grooves made in step 3, or, if you drilled 5/8" holes use the supplied clevis pin and spring clip to secure the WALKWAY LINK hardware in the 5/8" holes. See Figure 3.

Figure 3

5. Fasten uprights at every 6'-0" MAXIMUM to the ICF form work (block, panel or plank) WITH A MINIMUM OF ONE HAT BRACKET FOR EVERY 2'-0" HEIGHT, SPACED AT A MAXIMUM OF 2'-0" CENTER TO CENTER. Secure the brackets to the built-in strapping faces (or the area recommended by the manufacturer) of the ICF system using COARSE thread drywall or self tapping COARSE thread screws. This is to be done using a cordless drill equipped with a torque adjuster (not mandatory) at a low setting. IT IS EXTREMELY IMPORTANT THAT THE HAT BRACKET(S) REST ON THE ICF FORM WORK RATHER THAN BEING FORCED INTO THE FORM WORK MATERIAL. AFTER FASTENING THE UPRIGHTS, NAIL KICKER PLATES TO THE FOOTING OR FLOOR DIRECTLY UNDER THE UPRIGHTS BY LIFTING UPRIGHTS AND TOE NAILING THEM TO THE KICKER PLATES. THIS SERVES TO KEEP THE ICF FORM WORK IN LINE.
See Figures 4, 5, 6, 7, 8.
NOTE 2: DRILL SCREWS INTO THE CENTER OF THE ICF SYSTEM'S BUILT-IN STRAPPING (OR AREA RECOMMENDED BY THE MANUFACTURER). THIS WILL ASSURE THAT WASS IS FIRMLY SECURED.

Figure 4

6. Attach a 2" X 4" (regular stud) diagonal brace to the side of the uprights WITH TWO 31/2" NAILS PLACED DIRECTLY BELOW THE WALKWAY LINK. Slide two "C" Clamp Tighteners onto the brace, thread another 2" X 4" through the clamps and FORCEFULLY SECURE the brace studs together by tightening the screw handles of the "C" Clamps. SECURELY NAIL THE BOTTOM OF THE DIAGONAL BRACE TO A SOLID PICKET OR OTHER SOLID ANCHOR. See Figure 5.
NOTE 3: MAKE SURE THAT PICKET(S) AND/OR OTHER ANCHOR(S) ARE EXTREMELY SOLID AS THEY MUST HOLD THE DIAGONAL BRACES IN POSITION DURING CONCRETE PLACEMENT AND HOLD THE BRACES AGAINST THE WEIGHT OF WORKMEN ON THE WALKWAY. BE SAFE, DO THIS CORRECTLY !

Figure 5

7. After all uprights and diagonal braces have been installed, PLUMB ALL WALLS AND SECURE ALL HARDWARE. Proceed with walkway installation by hooking walkway brackets onto walkway links, KEEPING THEM CENTERED ON UPRIGHTS. THEN INSTALL 2" X 10" CERTIFIED SCAFFOLDING PLANKS on top of the walkway brackets MAINTAINING AN OVERLAP OF 4'-0" (FOUR FEET) WITH THE OVERLAP CENTERED AT EACH UPRIGHT.
See Figures 6, 7, 8.
NOTE 4: IT MAY BE NECESSARY TO INSTALL ADDITIONAL UPRIGHTS AND WALKWAY BRACKETS TO SUPPORT SHORTER THAN HEREIN SPECIFIED OVERLAPS.
NOTE 5: MAKE CERTAIN THAT ALL WALLS ARE SOLID AND SCAFFOLDING PLANKS SOUND BEFORE USING THE WALKWAY.

Figure 6

8. Insert and toe nail 2" X 4" vertical posts (48 INCHES IN LENGTH OR AS PER LOCAL SAFETY REGULATIONS) in the walkway brackets' open channels to serve as guard rail posts. Place guard rail support brackets on top of the posts and secure by nailing through the pre-drilled holes. Nail 2" X 4s" to the guard rail support brackets using the pre-drilled holes. MAINTAIN A MINIMUM OVERLAP OF 4'-0" (FOUR FEET) CENTERED AT EACH GUARD RAIL POST. USE MINIMUM 2" TO 3 1/2" NAILS TO JOIN THE OVERLAPS. If local safety regulations require, nail a 2" X 4" mid rail at the center of the guard rail posts and additional toe boards (2" X 4" or 1" X 4").
See Figures 6, 7, 8.
NOTE 6: MAKE SURE THAT YOU COMPLY WITH ALL APPLICABLE LOCAL SAFETY REGULATIONS FOR HEIGHT AND SPACING OF THE WALKWAY(S), GUARD RAIL, MID RAIL AND TOE BOARD.

Figure 7

9. Install remaining courses of ICF form work (blocks, panels or planks) and place concrete. Minor adjustments to ensure correct alignment of the wall will be required after concrete placement. Perform these adjustments BEFORE the concrete starts curing by using the WASS diagonal braces to align the wall to a mason's line.

IMPORTANT NOTES: THE WASS SYSTEM IS NOT TO BE REMOVED UNTIL SUFFICIENT CONCRETE CURE STRENGTH HAS BEEN ACHIEVED OR THE MINIMUM CURE TIME SPECIFIED BY THE DESIGN ENGINEER HAS BEEN MET. IN ALL CASES THE REQUIREMENTS INDICATED BY THE DESIGN ENGINEER TAKE PRECEDENCE. IF IT IS NECESSARY TO REMOVE THE WASS SYSTEM BEFORE SUFFICIENT CURE STRENGTH HAS BEEN ACHIEVED OR THE MINIMUM CURE TIME MET, CONSULT THE DESIGN ENGINEER FOR TEMPORARY SUPPORT INSTRUCTIONS.
