Bison Deck Supports: manufactured in the USA with 20 percent post-industrial recycled materials. Bison VERSADJUST, LEVEL IT, and SCREWJACK pedestals create level rooftop decks over sloped surfaces. Bison pedestals elevate and support Wood Tiles, Concrete Pavers, Site Furnishings and a variety of other surfaces when sophisticated, commercial grade decking is required.
Bison Versadjust, adjustable V-Series line reaches heights from 2-1/4 inches to 24 inches, has a 1250 pound weight bearing capacity and contains built-in slope compensation from 0 - 1/2 inch per foot slope. Joist Top is a Versadjust accessory that can convert Bison Pedestals into traditional joist and plank decking supports. Low Height pedestals can be used when low clearance is needed.
Bison Level.It deck supports are suitable for any project type from commercial to residential. One simple Level.It model LC covers heights from 2 inches to 4-3/4 inches. Additional accessories are available to compensate for slope and accommodate heights from 1/8 inch to 12 inches Model LC supports up to 750 lbs. Ideal for contractors or the do-it-yourself homeowner.
Bison ScrewJack pedestals are designed to support heavy pavers over any waterproofed structural surface. The Bison Screwjack pedestal (B-Series) reaches from 0 to 16 inches in height. Add couplers to reach up to 24 inches in height. Weight Bearing Design Capacity is 1000 lbs/pedestal FS:2.
Bison Surfaces: Bison wood tiles are commercial grade and available in standard and FSC certified species. Wood species include Ipe, Massaranduba and Cumaru. Bison 2 cm pavers are residential grade and available in 3 standard finishes that give the natural appearance of stone.
Bison Site Furnishings: Bison Cubes are modular planters made from high strength Aluminum and Ipe and come in an array of colors and finishes. Bison Cubes are designed to integrate with Bison Deck Systems giving the Architect complete design flexibility.

PART 3 EXECUTION
 
3.1
EXAMINATION
A.
Do not begin installation until substrates have been properly prepared.
B.
Substrate must be clean and free of projections and debris that could impair the performance of the pedestals or the total deck system
C.
If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2
PREPARATION
A.
Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
B.
Clean surfaces thoroughly prior to installation.
C.
Establish accurate lines, levels and pattern.
D.
Verify that substrate to receive the deck supports is structurally capable of carrying the dead and live loads anticipated.
3.3
INSTALLATION
A.
Install in accordance with manufacturer's instructions.
B.
For roof top applications provide the support required for each pedestal to create an adequate bearing surface using the method specified. Locate on the grid of each pedestal and where each measured grid line meets the perimeter.
C.
For on grade applications provide the support required for each pedestal to create an adequate bearing surface using the method specified. Locate on the grid of each pedestal and where each measured grid line meets the perimeter.
D.
Adjust each deck support to a "top of pedestal" elevation marked around the perimeter.
E.
Place deck supports along the grid lines. On larger decks, pedestals should be pre-sorted and pre-set to the proper elevation and placed in position prior to the installation of pavers or tiles.
F.
As the deck supports are placed and loaded with pavers or tiles, fine vertical adjustment can be made by rotating the base or bottom of the deck support. Clockwise rotation of the pedestal base will raise the bearing surface and the deck. Counter- clockwise rotation will lower the top bearing surface.
G.
Pedestals have built in height limit indicator ' bumps'. When pedestal is fully extended, height limit indicator "bumps" will be felt and heard, indicating the maximum height of the pedestal. Do not extend pedestal beyond the height limit indicators. Always maintain adequate thread engagement. Never over extend any pedestal.
H.
Use shims to compensate for slight irregularities in decking panel thickness. Place on top of the pedestal, under the corner(s) of the decking tile or paver. Use no more than 2 shims on top of the pedestal and always adhere 1/4 wedges with construction adhesive.
I.
Stackable Fixed Height Pedestals: Complete deck and grid layout as required. Stack no more than 4 fixed height pedestals together and place in lieu of adjustable pedestals where needed. Spacer tabs can be removed to accommodate perimeter and corner support locations.
 
** NOTE TO SPECIFIER **Include the following two paragraph for use with the Versadjust Series Pedestal System. Delete if not required.
 
J.
V Series Slope Compensation:
1.
Use integrated base leveler disks to compensate for up to 1/2 inch per foot slope. Additional slope compensation can be added by placing two additional LD4 disks under the pedestal base to compensate for up to 1 inch per foot of slope.
2.
Place the thickest edge of the disk (located on the edge by a small finger tab) at the down slope side of the deck support, one disk compensates for 1/4 inch per foot of slope. Using two to four disks, rotate one in relation to the other to create a level deck support.
3.
Shims may be used in multiples, whole or segmented, and placed under the base to level the deck support.
4.
All shims under a pedestal must be adhered to each other or the pedestal (NOT to the roofing membrane) with construction adhesive. Shim no more than 1/8 inch (3 mm) beneath each pedestal.
5.
On top of a pedestal: Use no more than 2 shims.
K.
Versadjust Series Bison Brace Pedestal Bracing:
1.
Pedestal bracing is required for added stability for Installations 24 inches - 36 inches in height and for Installations requiring additional stability.
2.
BB - S Short Bison Brace: Install around the outside perimeter of a walk deck where pedestals are installed where less than the typical 24 inch spacing occurs and shorter arms are required.
3.
BB - L Long Bison Brace: Install in the interior area of a walk deck where pedestals and 23-7/8 inch by 23-7/8 inch surfacing panels are installed providing uniform 24 inch spacing.
4.
Do not install deck surfacing panels until Bison Braces are properly installed.
 
** NOTE TO SPECIFIER **Include the following paragraph for use with the Level.It and ScrewJack Series Pedestal System. Delete if not required.
 
L.
Slope Compensation:
1.
Use a base leveler disk to level the pedestal base. Place one to four disks under the pedestal base to compensate for up to 1 inch per foot of slope. Compensate for slope by placing the disks' thickest edge (located on the edge by a small finger tab) at the down slope side of the deck support, one disk compensates for 1/4 inch per foot of slope. Using two to four disks, rotate one in relation to the other to create a level deck support.
2.
Shims may be used in multiples, whole or segmented, and placed under the base to level the deck support.
3.
Under a pedestal: All shims under a pedestal must be adhered with construction adhesive to each other - never to the membrane. Shim no more than 1/8 inch (3mm) beneath each pedestal.
4.
On top of a pedestal: Use no more than 2 shims.
M.
Deck Support Placement And Final Adjustment:
1.
Deck supports and deck surface panels shall be placed in accordance with the pedestal manufacturers written instructions. Use of paver lifters, is recommended.
2.
Pedestals are designed to be rotated for final slight adjustment when pedestals are fully loaded. Deck supports should be leveled in each succeeding row as the installation proceeds.
3.
Final height adjustment or maintenance is easily made by rotating the base in a clockwise or counter-clockwise direction to raise or lower the deck surface material.
4.
Additional sections of shims may be used and should be available for regular maintenance. Shims may be used in multiples, whole or segmented, and placed under the base or on top the pedestal to level the deck support.
5.
On top of pedestal use construction adhesive to adhere sections of shims. Construction adhesive is not required when using whole shims on top of a pedestal.
6.
Beneath a pedestal use a small amount of construction adhesive to adhere sections of shims and/or whole shims to each other or to the pedestal. Unless specified to do so, DO NOT use construction adhesive to adhere pedestal or shims to insulation, roofing or waterproofing membrane.
N.
Perimeter Containment:
1.
Any area of a deck that is not restrained by a parapet or foundation wall must be ' boxed-in' and contained. Deck panels will move if all sides are not adequately restrained.
2.
Perimeter containment located at the outside of the deck must be installed to provide restraint. No movement should be allowed at the perimeter of the deck system greater than 1/8 inch.
3.4
FIELD QUALITY CONTROL
A.
Inspect frequently during installation to assure that grid spacer lines are being maintained in a straight and consistent pattern and that deck panels or pavers are level and not rocking.
B.
Confirm that deck pedestal height does not exceed the specified height for the V Series:
C.
Inspect to assure that all paver spacing between tiles and at perimeter containment does not exceed a 1/8 inch. Particular attention should be made to assure that all pedestrian entry or access points to the deck are level and that the deck surface tiles are not randomly raised or uneven creating a tripping or safety hazard.
3.5
PROTECTION
A.
Protect installed products until completion of project.
B.
Touch-up, repair or replace damaged products before Substantial Completion.
3.6
CLEANING AND ADJUSTING
A.
Tile Cleaning: Clean wood tiles at the completions of the installation using methods and materials recommended by the tile manufacturer.
B.
Wood Tile Sealing: Seal wood tiles at the completions of the installation using methods and materials recommended by the wood tile manufacturer.
C.
Instruct the Owner about performing routine maintenance of the deck. Check for rocking pavers and adjust or shim immediately. Substrates can settle and pedestals may have to be readjusted. Failure to do so can cause a tripping hazard. Periodically check spacer tabs and immediately replace broken tabs to limit deck movement. Make sure the edge restraint stays intact and structurally sound.
3.7
PROTECTION
A.
Protect installed products until completion of project.
