Through continuousimprovement in quality and efficiency, Fabcon delivers high quality products andservices of exceptional value. This document provides GUIDELINES for designing precast concrete wall panels to Fabcon s MANUFACTURING and INSTALLATION tolerances. Basedheavily on the quality control manual for precast and prestressed concrete plantspublished by the Precast/Prestressed Concrete Institute (PCI) MNL 116, these tolerances reflect Fabcon s unique MANUFACTURING processes and patented a designer, manufacturer and installer of precast products, Fabcon delivers acomplete wall panel system.

2 These tolerances represent our acceptable MANUFACTURING and INSTALLATION GUIDELINES . They do not represent an exhaustive criteria for GUIDELINES are intended as a reference for licensed designers and construction professionals. Nothing in these GUIDELINES shall relieve the designer of record fromresponsibility for the structure s design and proper interface of the precast panelsystem with the building structure. Fabcon is not responsible for deficiencies in building - Fabcon may elect one or more of the following solutions: - Bring the product into tolerance by industry-standard repair methods. - Provide calculations that demonstrate that the product / INSTALLATION meets acceptable structural and architectural performance criteria. - Demonstrate that the completed systems meets acceptable structural and architectural requirements or offer modifications to meet design requirements.

3 Due to the inherent nature of concrete, hydration, handling, and shipping of precast, some chipping and or cracking may occur. product may require routine finishing such as blending for texture and color after INSTALLATION . Fabcon bases our scope of work on a completed wall panel system and specifically excludes project specifications granting the unilateral right to reject product that is correctable utilizing standard industryrepair methods or can be demonstrated to meet structural and/or architecturalperformance +Green WALL PANEL MANUFACTURING TOLERANCES N/A N/AN/A FABCONMNL116k2 = LOCATION OF STRAND Parallel to Plane of " [ 13mm] l1 = LOCATION of 1" [ 13mm] l2 = TIPPING and Flushness of Embedment ..

6 Even after final finishing, there will be a range of color and texture in the surface. Some variations are to be shown should be considered as GUIDELINES for an acceptable range and not limits for rejection. If these tolerances are met, the unit should be accepted. If these tolerances are exceeded, the unit may still be acceptable if it meets any of the following criteria: 1. Exceeding the tolerance does not affect the structural integrity of the unit. 2. The unit can be brought within tolerance by structurally satisfactory means. 3. The total erected assembly can be modified to meet all structural requirements. 2 FABCON WALL PANEL MANUFACTURING GUIDELINES SUPPLEMENT to PCIq = LOCATION of " [ 6mm] r = HEIGHT of + ", - "s = WIDTH of + 1", - "FABCONCROSS 3 4 a = Plan location from building grid " a1 = Plan location from centerline of steel " b = Top elevation from nominal top elevation.

9 It is the position dimensions of the primary erection control surfaces which should be controlled during erection. Theremaining position dimensions of the member features and secondary control surfaces of the member will be the result of the combination of the erection tolerances and the appropriate product tolerances. Erection and product tolerances for some features of a precast concrete member may be 5 DEFINITIONSCAMBER The deflection that occurs in prestressed concrete members due to the net bending resulting from the eccentricity of the prestress Interface space (distance) between two elements. Clearance is normally specified to allow for the effects of product and erection tolerances and for anticipated movement ( deflection, thermal movement).
