5 - 1 SIZES:

A. Panels are 4 feet wide and can be produced in lengths from 8 feet to 25 feet in increments of 8". Panel thickness ranges from 3 1/4" to 5 1/4" depending on thickness of polystyrene specified.

B. Dimensional tolerance - the tolerances shall comply with values listed in the manufacturers quality assurance procedures.

Note: Overall length ± 1/4" - 12' L or less, ± 1/2" - 12' L or more.
Overall width ± 1/8"
Overall thickness ± 1/4"
Location of truss wires within units ± 1/2"

5 - 2 STRUCTURAL TESTING:
Testing values of each panel shall meet or exceed those loads on Manufacturer's Load Design Charts. These charts were developed from results of tests conducted in accordance with ASTM E-72 and with provisions of ACI-318.

5 - 3 FIRE RESISTANCE:
Based on fire resistance calculations and the results of the Modified E - 108 Fire Test performed at Southwest Research Institute (SW RI Project No. 01-2601-407) the following fire resistance ratings may be assigned to the 3-D panels provided carbonate shotcrete is applied:

PART 6 - INSTALLATION

6 -1 Erection:

A. Prior to erection the contractor or his representative shall inspect the site and report to the construction manager any condition that may affect the proper installation of the panels. Installation should not proceed until these conditions are corrected.

B. 3 - D Panel installation shall be carried out in strict accordance with the latest edition of the Manufacture's Instructions for 3 - D Panel System Erection. For any field deviation from standard load design, values shall be calculated and approved and signed or sealed by a qualified architect/engineer.

6 - 2 Concreting Practice:
Concrete can be applied by several methods; however, all concrete shall meet a minimum of 2,500 psi. All shotcrete construction, including materials, equipment, preliminary preparation, proportioning, shotcrete placement, curing and quality control shall comply with ACI 506R-85 Guide to shotcrete.

6 - 3 Testing:

A. An important aspect of quality control is the physical testing of the concrete during and after placement. ACI 506.2 describes in full the procedures to be followed in construction testing.

B. Normal testing ages for compressive strength are 7 and 28 days; however, shorter periods may be required under particular application or conditions.
