Day One

• Dig and frame out the footers for the perimeter of the structure to the engineer’s specifications for depth and width.
• Set vertical rebar in concrete, like a fence post, just inside the footer form boards at predetermined locations.

Day Two

• Erect the pre-designed Bond Beam System on top of the vertical rebar poles. Our System has special corner and straight line connectors for the beams and can all be assembled quickly and easily without tools.
• Insert the Bond Hurricane Straps in the beam slits which are pre-cut at the exact locations required by the roof system. The straps have a “U” shaped hook on the lower end from which the steel curtain will subsequently be hung.
• Hang the specified horizontal rebar and Bond Shotcrete Steel Panels sandwiched between an exterior and interior sheet of 6X6 road mesh from the Bond Hurricane Straps. The panels will have been fabricated to a length equal to the height of the designed wall plus 3 inches for a 3 inch embedment into the concrete footer.
• You now have a three layer steel cage forming the exterior perimeter walls of the structure with the steel curtain extending 3 inches into the footer yet to be poured. Using a small acetylene torch, cut window and door openings. Window and door frames can be inserted in several ways according to builder preference.
• Install guide-wires along both sides of all perimeter walls that will be used as a guide to screed off excess shotcrete which helps create perfectly flat and even thickness walls.
• The horizontal rebar specified by the engineer for the footers can be suspended by curling upward the excess road mesh sheets extending deep into the footers thereby eliminating the need for saddles or chairs in the footer trenches.

Day Three

• Pour the concrete floor and footers thereby creating the embedment of the steel curtain in the footers and floor. This will also increase the rigidity of the steel cage.

Day Four

• Shoot the steel cage from both the inside and outside of the structure with shotcrete machines. Then screed and finish the concrete walls to desired thickness and finish (Bond walls are generally 3 or 4 inches thick). Because of the shotcrete process, the density of the concrete is generally in the range of 6000 to 6500 PSI rather than the 2500 to 3000 PSI generally obtained from poured concrete.

Day Five

• Remove the reusable Bond Steel Beam System and move it to the next structure which should already have the supporting vertical rebar steel set in concrete. Begin the process of erecting the next steel cage.
• The first structure is now ready to receive the roof system with the Bond Hurricane Straps tied into the rebar and sticking out of the top of the concrete walls in the exact locations where they are needed according to the roof system design.
