Tie Down Vector Dynamics Foundation System for Wind Zones IBC 2009 - Manual (Page 3)

GENERAL INSTALLATION INSTRUCTIONS
SITE PREPARATION
It is necessary that the home site be properly graded and sloped to prevent water and moisture from standing or
flowing beneath the home.
FOOTINGS AND FROST LINES
The Vector Dynamics Foundation System was designed to be placed directly on top of the ground (or poured
concrete) after clearing all loose vegetation. In areas with frost heave, use Vector for Poured Concrete (see pages
16 & 17) to comply with local requirements for footer depth.
FOUNDATION/FOOTING SPECIFICATIONS FOR VECTOR PADS
Vector Pads are used in place of conventional foundation pads. One Vector pad provides two or three square feet
of bearing support. Vector Systems should be spaced as symmetrically as possible along the length of the home.
For pier locations in between the Vector Systems, use the normal foundation pads.
LUMBER/MOISTURE - TERMITE SHIELD
To cut PVC or lumber (2 - 2x4’s,1 - 4x4 or 1 adjustable steel compression member per Vector system) for the cen-
ter compression section,when using concrete blocks for piers, measure center to center frame (I-beam)
distance and subtract 16”. When using METAL PIER STANDS, measure center to center frame distance and add
16”. ALL WOOD MUST BE PRESSURE TREATED, GROUND CONTACT RATED .
Pressure treated lumber (ACQ) must be isolated from steel parts by means of an effective and weather resistant
material or the steel parts must be galvanized to meet ASTM A153 and steel fastners in contact must be galvanized
to meet ASTM 653 or be stainless steel.
Tip: Pre-cut your lumber and mark as to brand or model of homes you will be installing. If frame widths
are the same, the pre-cut boards will also be the same length in each Vector set-up.
STRAP INSTALLATION
All frame ties and diagonal straps must go from the anchor to
the top of the I-Beam. See illustration below.
1. Attach frame hook to top inboard location of “I” beam.
(Frame hook must be attached to frame at points closest to
floor support.)
2. Keeping in line with the hook, wrap galvanized strap
completely around “I” beam.
3. Pull strap past anchor head approximately ten inches
before cutting to allow enough strap to give a minimum
of five turns around the slotted anchor bolt.
4. Thread loose end through slotted bolt so that the strap is
flush with the other side of the bolt.
5. Tighten slotted tensioning bolt a minimum of five full turns.
