1. Site Preparation

• Make sure footings are straight and level with a tolerance of +/– ¼"
• Place all Arxx form materials at least 6´ (1800 mm) inside the perimeter of the footings
• On the footings, clearly mark all door and window opening locations

---

2. First Course Placement

• Place a corner form on its mark and proceed around the perimeter of the building, placing forms as necessary
• For subsequent courses, start at the same corner and work around the perimeter in the same direction

---

3. Reinforcement

• Immediately following placement of the first course of forms, place any necessary horizontal reinforcing steel in the appropriate slots in the webs of the first course
• Be sure to observe the proper lap slice distances and the correct separation distances for non-contact splices
• Insert vertical reinforcing steel from the top of the wall

---

4. Door and Window Openings

• Door and window bucks are formed with a material suitable to hold back the concrete at the opening and provide adequate fastening surface for windows and doors
• Insert pre-built bucks in the wall as it’s built
• Insert reinforcing steel around all openings as explained
  in the Arxx Product Manual and according to design specifications

---

5. Wall Alignment

• Following installation of the 3rd or 4th course of forms, attach the Arxx Alignment System to the wall
• The Arxx Alignment System provides form alignment and a convenient scaffolding system that allows access to the upper portions of the wall

---

6. Concrete Placement

• Concrete can be placed in the wall using many methods—the most common method is the use of a boom pump
• We recommend double 90° corners to reduce the velocity of the concrete prior to its being placed in the wall cavity

---

7. Mechanical Installations

• For electrical rough-in, create channels in the foam using a hot knife tool or router
• Place wiring and fixture boxes into these channels
• Install plumbing using similar techniques as electrical installations—piping up to 1 1¼" trade size can be used without interfering with concrete thickness

---

8. Interior and Exterior Finishes

• The Arxx form wallsystem accepts your choice of finish materials, inside and out
• Depending on which materials you choose and your local building codes, finish materials can be mechanically fastened to the webs or applied to the wall with adhesive as required
• Available finishes include: Gypsum board, plaster, siding (wood, metal, vinyl, cement fiber), stucco, EIFS, brick, stone and log
