C. JOB SITE
C1. Scope Items of cold-formed steel to be installed shall be enumerated in the contract documents.
C2. Site Conditions
C2.1 The installer shall be permitted to use the most efficient and economical method and sequence of
installation or assembly available consistent with the contract documents. When The owner
contracts separately with a component manufacturer and installer, the owner is responsible for
coordinating work between contractors.
C2.2 The installer shall examine areas and conditions under which framing materials are to be installed.
Work shall not proceed until unsatisfactory conditions have been corrected by those responsible.
C2.3 The owner's representative for construction shall provide and maintain adequate access necessary
for equipment and framing materials to be installed. The owner's representative for construction
shall provide the installer level, convenient, and adequate space to safely use the necessary
equipment and install the framing materials.
C2.4 The contractor shall coordinate setting drawings, dimensional problems, compatibility of various
trades and/or installation.
C3. Delivery, Handling and Storage of Materials
C3.1 It is the receiving entity's responsibility to verify that framing materials arrive in good condition. If
framing materials arrive at a destination in a damaged condition, the receiving entity shall promptly
notify the material supplier or component manufacturer prior to unloading the framing material, or
promptly upon discovery and prior to installation.
C3.2 It is the contractor's and/or the installer's responsibility to verify the framing material is not
damaged and meets the project specifications and/or approved submittals before installation. The
material supplier or component manufacturer shall be responsible solely for the replacement of
damaged material or material that does not meet the project specifications and/or approved
submittals. If the contractor and/or the installer installs damaged material then the contractor
and/or the installer assumes the cost of repairing or installing new materials. At no time will the
consequential costs to be assumed by the material supplier or component manufacturer exceed the
selling price of the particular material in question.
C3.3 Damage caused by improper storage or handling of framing materials on the job site is not the
responsibility of the material supplier or component manufacturer.
C3.4 Proper storage of framing materials on the job site is the responsibility of the receiving entity, and
requires that framing materials not be in direct contact with the ground and are protected from the
elements. Adequate drainage and ventilation shall be provided to minimize the formation of "wet
storage stain" or "white rust".
(Reference - Code of Standard Practice for Cold-Formed Steel Structural Framing - 2006)
C3.5 Proper handling of framing materials on the job site is the responsibility of the contractor and
installer, and requires that care be exercised to not cause significant damage to the metallic
coating. Bare steel exposed at minor scuffs and scratches is generally protected by the zinc's ability
to provide cathodic protection and does not require any repair; however, significant damage to the
metallic coating, such as is caused by field welding, must be repaired in accordance with Section
C4.
C4. Field Modifications and Repairs
C4.1 If the contractor, sub-contractor or any others modify or damage framing materials, that party is
responsible for all costs necessary to analyze and, when necessary, correct the situation.
C4.2 Installation of holes in the webs of structural members is limited to the size, configuration,
and location as specified in the approved design or recognized design standard. Any webs of
structural members with holes violating the above requirements must be evaluated by the design
professional.
C4.3 Field repairs to damaged structural members shall be made in accordance with the design
professional's recommendation. The design professional may request that the specialty designer
provide recommendations on field repairs, with final approval by the design professional.
C4.4 Repairs to the metallic coating, when required, shall be in accordance with ASTM A780.
C4.5 Changes orders resulting from such approved field modifications or repairs shall be handled in
accordance with Section D4.
D. CONTRACTUAL RELATIONS
D1. Presentation of Proposals
All proposals for furnishing framing material shall be made on a sales contract form. After
acceptance by the owner, these proposals must be accepted or executed by a qualified official of
the component manufacturer and/or installer. Upon such acceptance, the proposal becomes a
contract.
D2. Acceptance of Proposals
All proposals shall have a specified term of acceptance. If the proposal is not accepted within this
term the proposal becomes invalid.
D3. Terms of Payment
The terms of payment for the work to be completed shall be specified in the contract documents.
D4. Change Orders
The component manufacturer and/or installer shall submit change orders for work that is determined
to be of no fault of theirs and will provide the owner's representative for construction with their
opinion as to which other trade on the project was at fault. These change orders may be
necessitated by any conflicts, in accordance with Section C1; discrepancies, in accordance with
Section C4; delivery, handling and storage of materials, in accordance with Section F3; or field
modifications and repairs, in accordance with Section F4. The owner's representative for
construction shall review the change order within fourteen (14) days, or sooner if the decision
delays the project schedule, and issue a formal response. The owner's representative for
construction's compensation of the component manufacturer and/or installer for conflicts,
discrepancies and approved field modifications and repairs shall not be delayed due to the
owner's representative for construction's negotiations with the contractor determined to be at fault.
E. PANEL DETAILS
1. DRAWINGS AND ELEMENT NUMBERS
Builders should study the appropriate drawings before beginning construction and assembly. If shop
drawings are provided by Transcon Steel™ they show an element number for each panel in the floor plan.
This element number appears on the top, bottom, and face of each panel. Panel drawings are viewed from
the interior. Note that the interior face of each panel has stamped the words "TOP" and "INSIDE".
2. ASSEMBLY
A. Sequence of Assembly
1. Unload the flat-bed trailer or containter at the job site. Stack the panels for each floor so that they
are in the necessary sequence for erection.
2. Protect panels from high winds and sharp impact.
3. Panels are usually set starting at one corner of the building and proceeding in a counterclockwise
fashion.
2.1 Preparation of the Foundation
A. First verify that dimensions of the slab or subfloor are in accordance with contract documents and coordinate with shop
drawings. These dimensions should be within the tolerances stipulated by the design professional and/or by good construction
practices.
B. Locate conduit stub-ups (if any) and drill holes in base plate.
C. The panels are attached to the foundation using steel channel track with anchor bolts or powder shot pins. Steel track shall be
set in a waterproof inhibitor such as roofing felt, foam tape, etc. Size and spacing of anchors shall be determined by a design
professional based on building code requirements.
D. Caulk and set base-track to building dimensions and secure to the slab or subfloor using anchors as per the design
drawings. Be sure the plates are level and the corners are square. If the foundation is not level, shim and grout with cement
to obtain a level basetrack.
*Do NOT try to obtain a level wall by shimming the panels.
E. Use an expansion anchor or nail-down anchor at each splice joint of the base-track.
2.2 Wall Assembly
A. The usual method of assembly is to pre-assemble wall sections and set them in place.
B. Sections are usually pre-assembled in 12 ft. to 16-ft. sections. A level work area at least 16 ft. x 12 ft. is required.
This area should be cleared of debris and a base line marked at the bottom and left hand side of the assembly area.
The marked lines must be true and square to avoid mis-alignment of the panels.
C. Once the assembly area is cleared and marked, consult the floor plan and determine which sections are to be
assembled and in what sequence. Using the element numbers as reference, obtain the necessary panels and lay
them out with the interior face down.
D. Caulk joints (if specified) and push the panels together.
E. Check the section for overall dimensions and for squareness. Once satisfied with the alignment, screw the panels
together with two screws through the exterior face of the clip angle as shown in Clip Detail. Locate conduit stub-ups
(if any) on panel and drill up from panel bottom to create chaseway (also, mark location on subfloor for future
locating).
2.4 Top Plates
A. Tie Sections together using structural u-channel steel top track (See specs). Cut the track on site to allow overlap to
the center of the next panel section steel stud at 12",16" or 24".
B. Connect the track to the Ultra Frame panel by fastening one screw through the top track and into the metal stud.
Repeat this for both sides of the wall. The top plate is permanently secured to the wall sections after the floor or roof
system has been set, which loads the wall.
C. In cutting the top plates or track, observe the following guidelines:
1. Where a wall section joins another wall section, overlap the top track to the next section center of steel stud at
12", 16" or 24".
2. Where a wall section joins a corner, the section top plate should overlap onto the corner to the full width of the
corner on one side and width of the corner less the wall thickness on the other side.
3. Where a wall section butts into another wall section, overlap the top plate the full thickness of the butt wall.
4. Gap between adjacent top plates (cutting error) shall not exceed 1/2".
5. Stagger top plate joints so that the joint does not fall directly over a panel joint, but does fall over the center of
an inner steel stud.
2.5 Setting the Wall
A. Mark the base-track with a permanent marker to the measurements of the wall panels.
B. When setting the wall panels, set each panel or group of panels to the base-track mark that is shown on the shop
drawing plans. This is to prevent the group of panels to grow or shrink in wall length when setting in place. Connect
the panels to the base-track as shown in details. Attach the overlapping top track to each other as shown in details.
C. Temporarily brace the top of the wall to the ground or floor so it stands true and plumb.
2.6 Openings for Doors, Windows, Etc.
A. Some panel openings are assemblies consisting of 2 or more components. These are shipped disassembled and
must be assembled on site. Refer to the data sheets provided and assemble these sections before setting them in
place. As in all assemblies, carefully check the unit for overall dimensions and squareness before setting it into wall
section.
3. QUALITY CONTROL
3.1 Inspection of Panels
A. Panels have been checked for density and fusion quality and for dimensions before shipment, but should be checked for
damage and spot-checked for dimensions as they are unloaded and stacked. For dimensional tolerances refer to 3.3. As a
general rule, any defect in the polystyrene core of the panel such as small cuts or nicks will not affect the integrity of the
panel. Damage to the metal will affect the panel's strength and integrity and can result in a rejected panel; refer to 3.2 below.
3.2 On-Site Changes
A. In general, any changes deemed necessary on-site must be cleared with the manufacturer before the changes are made.
The following site changes may be made:
1. Reject any panel with vertical steel members that have any buckles or dents. The panel can be salvaged by cutting
out the damaged section and inserting a wood or metal building stud. Fill gaps with insulation.
2. Bends may be straightened in the horizontal metal at the top and bottom edges of the panel.
3. Electrical Boxes. Use a hot knife or other acceptable cutting tool. Do not exceed the box dimensions and, where
possible, locate the box beside a vertical steel channel for screw attachment. Boxes should have recessed "ears" or
brackets behind the wall cladding.
4. Wiring or Conduit Chases. If chases provided are not used, vertical chases may be cut in to the polystyrene with a
hot knife or other acceptable cutting tool. Vertical chases shall be cut a minimum of 2" from any vertical steel channel.
3.3 Dimensional Tolerances
Panels:
Thickness ±1/8"
Panel Bow ±1/8"
Width +0", -1/8"
Additional Width Deviation @ mid height +0", -1/4"
Length ± 1/8"
Length difference between panels of same nominal length ± 1/8"
Diagonal squareness ± 1/8"
Door, Window, and other Rough Openings:
Width ±1/8"
Length ±1/8"
Diagonal squareness ±1/8"
3.4 Assembly of Panels
A. All bottom tracks must be level before the panels are set. If shimming is necessary to obtain level bottom track shim
(and grout) under the plate and not between the panel and plate.
B. Before making the final connections to the erected wall, the walls must be plumb.
C. Once the panels are in place for one floor the overall dimensions and squareness of the building should be checked
before proceeding with the assembly of any upper floor deck or roof system.
4. SAFETY
The panels may be handled by one or two persons. The following rules should be followed:
A. Gloves should be worn at all times when moving panels. The metal edges can cut and must be handled carefully.
B. Do not remove panels in high wind conditions. The surface of the panel will catch the wind and can create a potentially
hazardous condition.
C. If high winds are possible, panels must be sheltered, weighted, or otherwise protected from moving.
