About this file

This document is an offloading and installation instruction manual from Shelter Works, a manufacturer of prefabricated buildings. The document provides detailed, step-by-step guidance for properly installing and anchoring Shelter Works buildings on concrete slabs, with specific technical instructions for lifting, positioning, and securing the structures. While not a government contract document itself, the manual appears to be related to a potential state or local contract based on the provided government file metadata.

The instructions cover critical installation procedures including using overhead cranes for lifting, ensuring a level and properly sloped concrete slab, attaching nylon lifting straps, drilling and pinning corner anchors, applying base gasket sealant, inserting expansion anchor bolts, and weatherproofing seams and penetrations. The document emphasizes precise techniques such as maintaining a maximum 3/16" surface variance, sloping surrounding concrete at 1/2" per foot for drainage, and compressing base gaskets to no more than 1/4" thickness. Shelter Works offers a 25-year warranty and provides an installation video for additional guidance, suggesting a comprehensive approach to product deployment and customer support.

OFFLOADING & INSTALLATION

INSTRUCTIONS

FOR BEST RESULTS

Buildings should be offloaded using an overhead crane or similar lifting equipment with sufficient capacity for the load. Lifting, loading, unloading and installation should be performed by qualified, experienced personnel only.

Follow instructions provided by the project engineer or project owner.

For best installation results the slab upon which the building will sit must be true and level to a maximum surface variance of 3/16” where the building will interface with the slab. The slab immediately surrounding the building shall be sloped away at a pitch of 1/2” per foot to promote proper drainage and eliminate the potential of standing water around the building. At the time of installation the slab should be clean and dry.

STEPS

(1) Using shackles, attach 4 nylon straps to all 4 lifting eyes provided and lift from above using a single-point hook.

Straps should be at least 75% the length of the shelter (ex: If the shelter’s length is 20’ the straps should be at least 15’ long). Lift the building from the trailer.

(2) Orient and set the building in the desired location on the slab.

(Leave straps attached through step 11)

(3) In two opposite corners drill a 3/8” hole through the base flange of the building and into the slab. Temporarily pin the two corners to keep the building from moving. (3/8” diameter rod works great.)

BEFORE ANCHORING: The walls are somewhat flexible and may need to be temporarily braced to ensure they are straight before drilling more holes. A typical solution is to use lumber cut to length to span from one wall to the opposite wall. A tight string line from end to end on the outside of the wall will allow you to determine when the wall is straight.

(9) Place alignment pins through the base flange and into the drilled holes in the slab at the four corners and at the midway point of each wall to guide the building down the remaining couple of inches onto the slab.

(10) Insert expansion anchor bolts into all holes and partially tighten.

(11) Go around to each bolt a few times, tightening a little more each time until the bolts are snug and the base gasket is compressed to no more than 1/4” thick.

(12) Attach any items that were shipped loose (rain hoods, extra lights, etc.). Weatherproof the seams around these items with the provided color matched caulk. Field penetrations through the walls or roof should be sealed with silicone caulking to prevent water infiltration.

(4) Mark and drill all remaining anchor bolt holes through the base flange and slab (in accordance with anchor bolt manufacturer’s specifications) at the spacing indicated on Sheet 4 of the construction detail located in the submittal package.

(5) With a construction pencil or marker, trace the outline of the exterior of the building on the slab.

(6) Lift building off slab and sweep away any and all debris.

(7) Apply a row of Conseal base gasket to the slab, midway between the drilled holes and the traced outline of the building. Join the sealant into one continuous strand by kneading the ends together where they meet. Do not stretch or overlap sealant.

In colder weather warm the Conseal to 75º F before applying to the slab.

(8) Lower the building down to within a couple of inches of the slab.
