2.3  Allow at least 12 weeks for plants to firmly establish in nurseryenvironment

2.4  Orientate plants to growth from a wall by progressively tilting

VGM modules from horizontal to vertical over the 12 weeks

3. Prepare Wall for VGM Installation

3.1  Prime RC wall and/or construct framework (including

waterproofing, painting, welding, etc) according to project

requirements

3.2  Vertical beams of framework MUST correspond prec isely with

VGM width for pilaster installation

3.3  Erec t staging for work on high wall

4. Install Pilasters

4.1  Take vertical and horizontal wall measurements to determine

position of first pilaster (anchor rails) according to projec t

requirements

4.2  Drill holes at all securing points to required depth using drill bit

diameter corresponding with anchor used. Blow out dust and

fragments

Beam does not correspondwith VGM width

4.3  Pilaster positions MUST register with width of VGM and all

pilaster mounting slots align

4.3 

Use assembled VGM modules to assist in accurate alignmentof pilasters

4.5  Sec ure pilaster with stainless steel Stud or Wedge anchorstighten with torque wrench for RC wall or sec ure with stainless

steel nuts and bolts for a constructed framework accordingly
