2 General Notes Globalite Systems Aluminum Wall Forms! RECEIVING & STORING WALL FORMS & ACCESSORIES Upon arrival, forms should be stored in a safe level place. When removed from pallets, they should be laid face up on wooden battens with others stored on top in a face to face manner. All forms should be sorted by width and length and stacked accordingly. The inside and outside corners can be laid side by side. Accessories should be left in their cartons until needed. However the tools and tool boxes should be removed and stored separately.! PREPARING WALL FORMS FOR USE Forms that require electrical and plumbing accessories secured to the inside faces should be identified and prepared in accordance with details applicable to the specific accessory types. By referring to the modulation details, forms should be prepared for use in the order that they are required. Coating the forms and side rails with Break-in Aluminum Form Treatment will prepare them for their first use. Never use Globalite Aluminum Forms before they have been treated. Ensure that forms are dry before applying any kind of releasing agent. However, water in small amounts will have no effect after the releasing agent has been applied.! ERECTING WALL FORMS There are two specific methods used to erect wall forms: a). Inside to outside or b). Outside to inside. If most traffic is through the inside of the building, Method b should be implemented. With wall lines clearly marked out, the forms are erected starting from an outside corner and simultaneously proceeding in two adjacent directions. Using ties, pins and wedges at the five vertical pinhole connections will locate and secure the wall forms into one continuous panel. To avoid overdriving wedges, only hammers similar to those provided in the tool kit (14 to 16 ozs) should be used. Reinforcing wire mesh should then be installed by splice tying to starter bars and corner connections. Plastic spacer wheels are then installed in the required locations. Use Drift Pins that are furnished with Tool Kit to properly align forms. Drift Pins must be used in 3/8 (9.50mm) Ø utility holes only. Never align forms by using the Slotted Tie Pins in the Tie Holes. In order that it may be supported vertically, mesh may be wire attached to the wall ties. Starting at the inside corner, interior wall forms are then erected in the same manner and parallel to the exterior forms. As this operation proceeds, the wire mesh should be cut free from any temporary wiring to ties in order that the plastic wheels may be encapsulated by the forms to securely hold the mesh in the centre of the wall-form cavity. During erection, wall braces should be used to progressively plumb and stabilize the forms until closure on all sides is completed. The final adjustment of wall alignment and vertical plumb to all forms is carried out and secured by the use of Waler Brackets, Aluminum Walers and Wall Braces, as and where required.! CONCRETE: DEFINITION, DELIVERY & PLACEMENT Although the requirements and specification of concrete is the responsibility of the engineer of record, the following is an outline of the type of concrete found to be suited to aluminum forming systems. Subject to the varying characteristics of the local geology, the following should be considered: Coarse Aggregate Maximum size ½. SG = Fine Aggregate F.M = 2.75 average. SG = (Sand with an F.M. in excess of 2.95 will not result in a perfectly smooth concrete finish). Cement BSS 12 Grade 20 or Portland Cement Type I (or equal) Additives Plasticizer (Water Reducing Agent - WRA) Air entrainment None required. Entrapped air approx 2%. Water The minimum necessary to ensure proper mix of components. Amount is predicated on the weight of cement used and should not exceed 60% of that weight. Slump For best results, slump should be a minimum of 8 at point of concrete placement. This high slump is achieved and maintained by the addition of plasticizer. The best delivery method for concrete walls is by pump. This method ensures a controlled flow into the forms and permits the concrete to percolate to the bottom of the forms. Concrete placement should commence at the corners of the formed walls and distributed by puddling to the rest of the wall areas. Puddling is carried out by the use of smooth thin wooden poles that extend to the bottom of the forms. In order to prevent scoring the form faces, the poles must be only of wood. Rebar or other metals should never be used for this purpose. Puddling should be carried out with short vertical movements of the pole. When puddling a fresh pour over a previous layer, the puddling rod should extend at least 12" into the older lower layer. Special care should be exercised with concrete placement around apertures in the forms, such as doors and windows. When placing concrete around windows, concrete should be poured on one side of the window until it has passed under the sill and clearly appears on the other side at sill height. At this point, pouring may commence on the other side of the window. If vibrators are additionally, or alternatively, used to consolidate concrete, only persons skilled in vibrating techniques should use them. They will exercise the

3 correct timing and keep the vibrator at the center of the space between the reinforcing and the form face and avoid over-vibrated pockets in the finished concrete.! CONCRETE (continued) Correctly placed and vibrated concrete produces superior finishes. The vibrator most recommended is a round 1" to 1 1/4" diameter lightweight pencil type with a frequency of 9,000 to 12,000 RPM (either electric or air driven). The head should be free of angled edges. Lower frequencies should be avoided. When finishing concrete at the top of the wall, a convex cross-section of about 1/4" in height at the center of the wall should be formed. This will compensate for contraction, particularly if full-slump or plasticized concrete is used.! FORM WASH AFTER EACH CONCRETE POUR With the concrete pour completed, the backs of the forms should be thoroughly washed down (preferably with a high-pressure water hose) to ensure that no concrete or cement residue remains on the outside faces of the forms. Even the top rails of the forms must be washed & wiped clean to bring the forms back to a pristine condition before the forms are removed. As dried cement or concrete is difficult to remove, fast & easy on-going maintenance such as this will dramatically enhance the life and efficiency of the forms.! FORM REMOVAL When approved by the engineer of record that the concrete wall is ready for form removal, the following simple procedure is suggested: Remove all wall braces, walers, waler clamps and aligner brackets before removing pins and wedges. To remove the wedges, the head of the pin is struck with a hammer whilst the wedge is pulled and removed by hand. With the wedge removed, the pin is easily extracted. Failure of wedge to release is an indication it has been over-driven. By tapping the bottom of the wedge upward with a hammer, it will release. Because the hammer often "Hits form twice and wedge once," this method is discouraged. With the use form pullers, form removal commences at center of walls and moves out in both directions, using a puller, when necessary, on the side of the form that has a neighbor. Never attempt to pry between wall and form face. Stubborn singular forms can be removed by using a 2" x 4" batten between wall face and form puller.! CLEAN UP After removal, form side rails should be cleaned and, with form face, oiled with releasing agent in readiness for the next use. Stubborn deposits on form faces may be cleaned with the fibre brushes supplied in the tool kit. Under no circumstances should any other kind of brush be used. With a little care and attention, the form faces can remain pristine through many reuses. Although the use of form oil is recommended for cleanup, when used as a releasing agent (other than break-in) oil should always be applied just prior to actual form use.! FORM LOGISTICS & CYCLE PLANNING The first setup of the wall forms will be a trial-and-error exercise that will be the most important part of getting to know the system s application for a particular project. Once in place and ready for the first pour, each form will be labeled to identify both its size and unique location. Since each structure will be somewhat repetitious, each form will occupy the same relative location for the forming and pouring of each structure. The exterior form panels will be moved to the next location, erected and temporarily held in place with wall braces. Interior panels will then be moved through the doors to first relocate and form the interior wall faces of the outside wall forms now in place. From these window walls, the rest of the setup is concentrated on the interior forms which will progress around the rooms, repeating the functions carried out on the first structure. As each form occupies the same location for every structure, the switch boxes, blockouts, and chases will be identically located. As the work proceeds, the identity and shortest distance between the locations of each form will soon become evident. There will always be exceptions to the above. Use of common sense and practical knowledge gained from experience should be initiated.! NOTE ON CONCRETE MIX DESIGN The information provided is purely for cosmetic purposes only to suggest what provides the best finishes for concrete walls and does not in any way imply that it will be the best structural concrete mix design. This decision rests solely with the structural engineer of record. For Questions or Enquiries! Please contact Structural Contours, Inc. at or via facsimile at or via at sci@sciglobal.com!

4 General Notes Globalite Systems Slab Falsework & Formwork! Maintain a copy of the Engineered Equipment Layout Drawings on the project site at all times.! Adjustable Steel Post Shores must always be erected plumb on a level surface that is capable of supporting the imposed loads.! Where indicated on the engineered equipment layout drawings, place a Shoring Jack Clamp on the Shore and attach Clamp to existing snap-tie in concrete wall. This will stabilize Shores during erection of the Aluminum Stringers. The Shoring Jack Clamps furnished for the project must be field adjusted for either the 4, 6 or 8 distance from face of wall to center of Shore. Once adjusted and fixed to the Shores, they should be left on the Shores throughout the duration.! Where Aluminum Stringers must overlap within the U-Head of a Shore, a Shore with an 8-1/2 Wide U-Head must be used. Refer to the engineered equipment layout drawings to determine where these locations are.! Erect Aluminum Stringers after Shores are placed. Stringers must be level.! During erection of the Stringers, each Aluminum Stringer must be clamped to the U-Heads of each Shore with an Aluminum Clip Assembly, T-Head Bolt and Hex Nut to prevent Stringers from rolling or tipping.! Erect all Aluminum Joists after all Stringers have been securely erected and clamped. Aluminum Joists must be placed to allow plywood joints to occur directly over the Nailer of the appropriate Joist. Refer to the engineered equipment layout drawings for correct placement locations of all Aluminum Joists.! Place ¾ thick Plywood Slab Form Panels as indicated on the equipment layout drawings. Nail plywood panels using 1-1/2 finish nails near each corner and several locations along the length and width of the edges of the Panels. Do not over nail, as this will cause premature deterioration of the Plywood Slab Form Panels. New Plywood Slab Form Panels will require less nailing than after repeated use. Nailing is required to maintain as smooth a flat and level Plywood surface possible, so as to minimize finishing of the concrete at the plywood joints.! Apply a fine, spray coating of Form Release Agent to the Plywood Slab Form Panels prior to installing the slab reinforcing and other trade materials. Do not over apply the Form Release Agent. Never apply Form Release Agent to the slab reinforcing wire or bars.! After the slab formwork, slab reinforcing steel and all electrical, mechanical and plumbing work has been completed, inspect all Shores for plumb and adjust if necessary. Check slab formwork to ensure that it is level.! Tighten the adjustment device of each Shore. Do not over tighten as this may cause the slab formwork to become out of level.! Before placing concrete on the Slab Form System, check that all reinforcing steel has been properly placed and tied, using the necessary proper reinforcing accessories as may be required by the Engineer s drawings and/or specifications.! Check that all Electrical, Mechanical, Plumbing, etc. equipment has been securely placed according to the Architect s and Engineer s Plans and Specifications.! Place all screeding devices on the Slab Form prior to placing concrete. Be sure that all screeding devices are properly adjusted so as to ensure a flat, level concrete slab surface after concrete finishing has been completed.! Install the slab pour stop formwork. Slab pour stop forms shall be field fabricated in wood by the contractor. (Applies only when multiple pours are necessary to complete concrete placement at one floor or roof slab level)! Prior to pouring the concrete slab, the falsework and formwork must be inspected by the contractor who is responsible for placement of concrete.! Do not pour concrete floor or roof slabs should rain be forecast, as rain may cause undesired damage to the surface of the slab, and may restrict proper curing of the concrete.! Before removing the Slab Formwork, review the Engineer s Specifications to determine the allowable concrete cure time necessary before removal of the falsework and formwork may begin.! To begin, loosen the adjustment device of the shores, and remove the Aluminum Clip Assembly that clamps the Aluminum Stringers to the U-Heads of the Shores.! Carefully remove the Shores and Stringers, being sure to not allow them to fall from above, as this may cause injury to a worker, cause damage to the concrete floor below, or damage to the equipment.! Remain observant that Aluminum Joists do not fall from above during the removal of the Falsework equipment. Use of Rolling Towers is suggested for this function.! Remove the Aluminum Joists by carefully prying away from the underside of the Plywood Slab Form Panels. Small wooden wedges may be used if necessary. If proper nailing was done, the Joists should become separated from the Plywood Panels with relative ease. Caution should be exercised should there be nails that have remained in the Nailer of the Aluminum Joists.! Removal of the Plywood Slab Form Panels should be done with relative ease if properly coated with Release Agent, and butt joints were tight. Thin wood wedges may be required to remove the initial Panel, or the insertion of a small screw device at the underside of a Panel may be necessary for the purpose of having a means with which to pull a Panel from the slab. After removal of all Panels, they

5 should be properly cleaned with water and firm fibrous brush and plastic scraper. No wire brushes or steel tools must be used.! If Plywood Form Panels are not immediately moved to the position of next use after cleaning, they must be stored on flat, level blocking until needed. Plywood Form Panels must be cleaned after each use and a fresh coating of Release Agent must be applied before re-positioning at the next location of use.! All Falsework Equipment, Formwork Equipment, Plywood Panels, etc. must be securely stacked and/or banded so as to ensure safety during lifting from floor to floor.! Provide routine cleaning and maintenance on a regular basis for all slab formwork equipment as may be required to ensure safety and proper usage.! Never use equipment that has been bent, split or damaged in any way. Damaged equipment must be removed to a location where it cannot be inadvertently used in error.! Replace all damaged equipment with equipment considered to be adequate and safe. Safety Equipment & Guard Rail System Notes! If Guard Rail & Safety Rail equipment has been furnished with this system, its use at all times is suggested to provide worker protection.! Be sure that the Safety Rail equipment is properly fixed to the Globalite Aluminum Forms or the concrete walls (Bracket fixes to Snap-Ties), whichever is the appropriate application. See Engineered Equipment Drawings for information on this equipment.! Right Angle Couplers for Guard Rails are not required at each Guard Rail Post, but should not exceed 8-0 o.c. maximum spacing. (Applies only to steel pipe Guard Rails)! The Guard Rails must be erected inboard of the Guard Rail Posts at all times.! Guard Rail equipment must be re-positioned as work progresses. If perimeter and/or edge protection is required for an entire floor area, contractor must furnish this equipment as necessary.! It is suggested that impalement prevention devices be used at all protruding reinforcing steel bars and/or WWR fingers throughout the duration of the concrete construction.! Workers must use personal protection equipment at all times as may be required by federal, provincial and local building codes and ordinances.! Workers must comply with all federal, provincial and local building codes and ordinances that apply to the safe and proper use of falsework and formwork equipment. Walkway Equipment System Notes! SCI Walkway Equipment has been furnished with this system and its proper use and handling is mandatory at all times. Please follow the Engineered Equipment Layout Drawings provided.!
