		H.	Decks over roofing and waterproofing:
			1.	Where integral roof insulation is installed immediately below the membrane, roofing systems having common insulations with a medium density of 20 psi must install Bison Floating Insulation Bases (FIB) immediately below the Bison Deck Support Pedestals to disperse the deck load.
			2.	Where high density closed cell extruded 60 psi polystyrene insulation is installed on top of the membrane in a protected membrane system, Bison Deck Support Pedestals may be installed directly on top of this type of insulation.
			3.	Do not use Bison Deck Supports over any insulation less than 20 psi or with low density polystyrene (bead board) insulation.
		I.	Decks on Grade:
			1.	Any substrate soil that is to receive pedestals shall be adequately compacted and have positive drainage slope. A "walkway gravel" base (ie: 1/4 inch Minus or 'breeze') should be installed and compacted at Bison Deck Support locations.
			2.	Bison Floating Foundation Bases (FFB) must be used beneath all on grade Bison Deck Support decks. Level the surface and set directly on grade as a base.
			3.	A wall or perimeter containment on all open sides is required. Install an edging board frame that restrains the decking system.

	PART 3	EXECUTION
	3.1	EXAMINATION
		A.	Do not begin installation until substrates have been properly prepared.
		B.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
	3.2	PREPARATION
		A.	Establish accurate lines, levels and pattern.
		B.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
		C.	The substrate surface that will receive the deck supports must be well compacted or structurally capable of carrying the dead and live loads anticipated.
		D.	The substrate must be clean and free of projections and debris that could impair the performance of the pedestals or the total deck system.
	** NOTE TO SPECIFIER ** Delete the next paragraph if Pedestals are not installed in conjunction with roof systems. Retain the next paragraph only if an IRMA (PRMA) configuration is specified.
		E.	Decks over roofing and waterproofing: Verify that installation conforms to section "Project Conditions - Decks over Roofing and Waterproofing".
		F.	Decks on Grade: Verify that installation conforms to section "Project Conditions - Decks on Grade".
		G.	Installation requirements vary for each individual project site. Deck materials used, pattern, grid layout, starting point, and finished elevation should be shown on plan view shop drawings which have been prepared and approved by the designer, installing contractor and/or owner.
		H.	Once a starting point and the finished elevation of the deck surface have been determined, the support system elevation (finished elevation less deck material thickness) is established and marked around the perimeter using a transit "torpedo" water level or laser leveling device.
		I.	Precise measurements should be taken and deck area should be accurately defined. Mark off and square all outside edges with control lines (chalk lines or spray paint). Install two (2) lines that are perpendicular to each other across the deck area. Continue to mark a grid of lines in both directions marking the location of each pedestal. To assure a square layout, use the control lines as references to periodically check the layout during installation.
	3.3	INSTALLATION
		A.	Install in accordance with manufacturer's instructions.
		B.	For installations on smooth surfaced roofing/waterproofing, place a piece of protection board in the location on the grid of each pedestal.
		C.	Place deck supports where each measured grid line meets the perimeter. Remove two (2) spacer tabs in line with one another on top of each deck support placed around the perimeter. Remove all four (4) spacer tabs at corners.
		D.	Adjust each deck support to a "top of pedestal" elevation marked around the perimeter. Normally the deck support is positioned as close to the perimeter as possible, with the two remaining spacer tabs aligned with the grid line. Using the "top of pedestal" elevation marked on the perimeter, stretch a mason's line along and slightly ahead of the second row of deck supports. A laser leveling device may also be used for this purpose.
		E.	On larger decks, it is recommended that pedestals be pre-selected and pre-set to the proper elevation and placed in position prior to the installation of pavers or tiles.
		F.	As the deck supports located along the grid lines are 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 bearing surface.
		G.	If the "safety windows" located at the base of the screw cylinder become visible, it indicates that the deck support is extended beyond the minimum required engagement of threads. A coupling unit must be added to achieve the desired height. Never use a pedestal when the safety windows are exposed.
		H.	Slight irregularities in decking panel thickness can be compensated for by using one or more shim segments. Place on top of the pedestal, under the corner(s) of the decking tile or paver. Use no more than two (2) shims and always adhere 1/4 wedges with construction adhesive.
		I.	Fixed Height Pedestals: Complete deck and grid layout as instructed above. Stack no more than four (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.
		J.	Slope Compensation:
			1.	Preferred Method: A base leveler disk should be used to level the pedestal base. Place one or more 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 or more 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.
				a.	Under a pedestal: All shims under a pedestal must be adhered with construction adhesive. Shim no more than 1/8 inch (3mm) beneath each pedestal.
				b.	On top of a pedestal: Model D11 - Use no more than 2 shims. Model PS1 Use no more than one shim.
			3.	Use top mounted adjusting leveler disk, PH5, to compensate for slopes up to 5/8 inch per foot. Turn the top leveler disk to expose a number from 1 to 5 in the sight window (1 = less slope, 5 = more slope). Locate the arrow on the top of the leveler disk that corresponds to the number in the sight window. Place the deck support so that the numbered arrow points directly downhill.
		K.	If a specifier requires and desires to install a cavity deck system over the height of 16 inches maximum of 24 inches in height, special approval is required prior to commencing the installation. The installing contractor must furnish Bison Deck Supports the proposed design for the extreme height bracing, stamped by a professional, licensed engineer. Special written approval will then be furnished by Bison Deck Supports to the installing contractor with a copy to the specifier, prior to commencing any pedestal and decking work.
	3.4	DECK SUPPORT PLACEMENT AND FINAL ADJUSTMENT
		A.	Deck supports and the deck surface panels must be placed as the manufacturer directs in these written instructions. Use of labor saving devices, such as paver lifters, is encouraged, especially on large jobs.
		B.	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. Final height adjustment or maintenance is easily made by simply rotating the base in a clockwise or counter-clockwise direction to raise or lower the panel.
		C.	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 to level the deck support. All shims under a pedestal must be adhered with construction adhesive.
	3.5	PERIMETER CONTAINMENT
		A.	Any area of a deck that is not restrained by a parapet or foundation wall must be 'boxed-in' and contained. The deck panels will move if all sides are not adequately restrained.
		B.	Perimeter framing and edging boards located at the outside of the deck perimeter must be installed to provide restraint. No movement should be allowed at the perimeter of the deck system greater than one tab width.
	3.6	FIELD QUALITY CONTROL
		A.	Inspect often 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 16 inches (406mm) in height. Confirm that pedestal heights in excess of 16 inches (406mm) have been braced and that proper authorization has been received.
		C.	Unless otherwise specified in writing to allow for expansion, inspect to assure that all paver spacing between tiles and at perimeter walls does not exceed a tab width. Particular attention should be made to and deck supports 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.
		D.	Immediately following installation, the Owner, or the Owner's representative, must inspect the deck system to be positive that:
			1.	The new deck system is adequately blocked on all sides to contain the surface decking and related components.
			2.	There is no more than tab width spacing between any deck panels and at all sides of the deck perimeter.
			3.	There is no ballasting rock used to fill in any perimeter voids.
			4.	There is no 'rocking' of deck panels as foot traffic is applied to the surface decking.
			5.	All required spacer tabs are in place and visible.
	3.7	PROTECTION
		A.	Protect installed products until completion of project.
		B.	Touch-up, repair or replace damaged products before Substantial Completion.
	3.8	ROUTINE MAINTENANCE AND CARE
		A.	Installer and/or Architect has a duty to instruct the deck owner about performing routine maintenance of the deck. Check for rocking pavers and adjust or shim immediately. Pedestals can settle and may have to be realigned. 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.
