Prepare and Square the Building Site
PREPARE THE BUILDING SITE
A level site is required to accurately and safely construct
the building. Consult the services of a qualified contractor
to properly grade and prepare the site.
Site should slope away from the building for proper water
drainage.
After the site is prepared, mark the location of the frame
corners to square the frame position. Taking these steps
before
assembling the shelter saves time and ensures
that the structure is square and positioned as desired.
The following procedures are suggested methods.
Their use depends on the size of the shelter, shelter
application, the footings (if applicable), and the method
used to anchor the shelter.
When in doubt, consult the services of a qualified
contractor experienced with the construction of similar
structures.
Ground Posts
If the frame includes ground posts, set all ground posts
as described within this manual. Width of the shelter
is measured from the center of one ground post to the
center of the remaining ground post. Length is also
measured center-to-center.
lding includes ground posts, continue with the Set
Ground Post section. Review the layout diagrams for
additional details.
Enlist the services of a professional and competent
contractor to prepare the site and set the ground posts.
Failing to secure ground posts in concrete as required
may result in damage to the building, building contents,
and surrounding property.
Rafter Mounting Feet
If your frame includes mounting feet, prepare the site and
anchor the feet to the site before assembling the frame.
Read the following information and use the diagram to
layout the position of your building. Once the string lines
are set to mark the location, continue with the Mounting
Feet section.
Unless you are securing feet to concrete piers, do not dig
holes if your building is equipped with rafter mounting feet!
Read the information on the Mounting Feet (if equipped)
page for additional details.
SQUARE THE SITE: GENERAL STEPS
1. Identify a corner where a building rafter will be
positioned, drive in a stake, and string a line the exact
width of the building and stake in place. (Width of the
rafter is measured from center-to-center of the rafter
legs.)
2. After the first corner stake is in place, string a line the
width of the building (center-to-center) and drive the
second corner stake into the ground.
3. String a line at least as long as the building 90° from
the line between the first and second stakes.
NOTE:
A transit can be used to ensure an accurate
90° angle, or the 3-4-5 rule can be used. Refer to
diagram. Using multiples of 3-4-5 such as 6-8-10 or
12-16-20 helps to maintain an accurate 90° angle.
4. After squaring the position of the building, measure
the length and drive the third corner stake.
5. Repeat the same step for the last corner stake.
NOTE:
The distance measured diagonally between
corner stakes must be equal for the building to be
square.
6. If purchased greenhouse includes ground posts,
continue with the "Set Ground Posts" section on the
following page.
If purchased greenhouse includes mounting feet, skip
to the "Mounting Foot Installation" pages.
NOTE:
If attaching mounting feet to a slab, consult
and follow local and regional building codes for slab
requirements.
