Please note that the scorecard is subject to change throughout project development and construction, and will be updated as necessary. Updates will be communicated by the Project LEED Consultant to the Contractor LEED Coordinator, and the Contractor LEED Coordinator will ensure all Subcontractors and other related parties are also immediately aware of the updates. 1.4 Referenced Standards.1 Unless specifically noted otherwise, all work performed under this Contract shall comply with the following codes and standards: 1.5 Design.1 British Columbia Building Code 2006 Edition.2 CSA Standard A CSA Standard S269.1 Falsework for Construction Purposes.4 WorkSafe BC Accident Prevention Regulations.1 The design and engineering of all formwork is the responsibility of the Contractor..2 Engage the services of a Registered Professional Engineer to design and inspect all concrete forms, falsework, shoring and reshoring..3 Design formwork to safely carry the vertical and lateral loads specified by CSA Standard S Provide forms with sufficient strength and rigidity to withstand pressures resulting from placement and vibration of concrete and to maintain specified tolerances..4 Product erection drawings detailed in accordance with CSA Standard S Specify size, type, grade and location of all components together with construction tolerances and design loadings. Drawings shall indicate all requirements for removal of forms, shoring and reshoring sequences and shall bear the seal and signature of the Designer.

4 Project No Page 4.5 Submit formwork drawings for review by the Consultant upon request..6 Design column forms to accurately limit the height of concrete columns to the underside of the concrete slab..7 Design slab forms to include construction loads to suit construction methods and procedures. 1.6 Quality Assurance.1 Provide at least one person who shall be present at all times during execution of this portion of the Work and who shall be thoroughly familiar with the type of materials being installed, the referenced standards and the requirements of this Work, and who shall direct all Work performed under this Section. 1.7 Approvals.2 Approvals of materials, methods or drawings shall in no way relieve the Contractor of his responsibility to make all Work complete, accurate and to remove and replace all defective Work at his own expense whenever such defects are discovered. 1.7 Product Handling.1 Obtain delivery of all materials supplied under other Sections and to be installed under this Section. Obtain latest revisions of approved setting drawings, instructions and template. 1.8 Protection.1 Use all means necessary to protect Cast-In-Place Concrete materials before, during and after installation and to protect the installed Work and materials of all other trades..2 In the event of damage, immediately make all repairs and replacements necessary to the approval of the Consultant and at no additional cost to the Owner. PART 2 PRODUCTS 2.2 Materials.1 Formwork Materials.1 Rough-Form Finish All concealed concrete surfaces and interior concealed concrete surfaces of all elevator shafts, trenches, and sumps use plywood to CSA-O151 or O121, board form G1S minimum ¾, or steel panels.

5 Project No Page 5.2 Form Oil.3 Form Ties.2 Smooth-Form Finish Exposed exterior and interior concrete surfaces at Ground Floor and Parking Levels, and exposed interior concrete wall surfaces of Exit Stairs, and storage and services areas use precoated form ply sheets Plyguard or approved equivalent..3 Architectural Concrete Finish Exposed exterior concrete surfaces and surfaces above grade (Refer to Section Architectural Concrete for formwork materials)..1 Non-staining colourless mineral oil free from kerosene, and as recommended by Form Ply Manufacturer..1 Exposed concrete surfaces use metal snap ties equipped with 1 diameter by 1 deep plastic spreader cones..2 Non-exposed concrete surfaces removable or snap-off metal ties equipped with integral spreaders. 2.2 Alternate Forming Systems.1 Alternate forming systems maybe used subject to the advance approval of the Consultant. 2.3 Other Materials.1 All other materials, not specifically described but required for proper completion of concrete formwork, shall be as selected by the Contractor subject to the advance approval of the Consultant. PART 3 EXECUTION 3.1 Preparation.1 Verify lines, levels and column centres before proceeding with formwork. Ensure that dimensions agree with drawings. Report any discrepancies to the Consultant before proceeding..2 Carefully examine the drawings, all shop drawings and the specifications and consult with other trades to determine requirements for provision of blockouts, sleeves, chases and embedded items..3 Provide temporary openings at bottom of wall and column forms and at other locations required to permit cleaning and observation prior to pouring.

6 Project No Page 6.4 Provide 45 degree ¾ nominal chamfer to the corners of all permanently exposed concrete surfaces..5 Terminate internal tie systems not closer than two (2) diameters or twice the minimum dimension of the tie from the formed faces of concrete to be permanently exposed to view, except that in no case shall this distance be less than ¾..6 Use form ties so that ends can be removed without appreciable concrete spalling. Grout all holes..7 Coat all form surfaces with approved form release agent prior to placing reinforcing steel and concrete..8 Provide cambered formwork to suit cambers as indicated on the drawings and in the general notes shown on the structural drawings..9 Provide details of camber procedures for review by the Consultant..10 Clean forms and embedded items free from accumulated mortar or grout from previous concreting and from all foreign matter. 3.2 Exposed Concrete Surfaces.1 Ensure jointing of facing panels and locations of ties is orderly in arrangement. Location of joints and ties is subject to approval by the Consultant, minimum spacing of form ties 24 oc each way..2 Use new forms for this project. Do not reuse any forms if there is evidence of any defects which would impair the quality of the surface..3 Thoroughly clean and properly coat forms as recommended by the Manufacturer before each reuse..4 Continuously observe formwork while concrete is being placed and check that no deviation from the desired alignment, elevation, plumb or camber occurs. If such deviation occurs or a weakness develops stop the work, repair all damage and strengthen formwork. Remove and replace permanently damaged construction. 3.3 Inserts.1 Set reglets, ties, anchor bolts and other inserts, blockouts, chases and sleeves in concrete walls, as required by other trades..2 No sleeves, ducts, pipes or other openings shall pass through beams or walls except where detailed on structural drawings..3 Check all sleeves, openings, etc shown on structural drawings with the architectural and mechanical drawings. Sleeves, openings, etc not shown on the structural drawings must be approved by the Consultant.

7 Project No Page Tolerances.1 Construct forms of sufficient strengths and rigidity in order to prevent leakage of mortar and to ensure that movements and deflections are limited to an amount such as the finished product complies with the following tolerances: refer to structural drawings. 3.4 Inspection.1 Obtain inspection and approval of formwork by the Designer immediately prior to pouring..2 Continuously inspect formwork during and after pouring.
