Site Preparation and Platform Construction
Materials NOT supplied with Shed Kit
Important:
• Site preparation is required for this shed. Placing the shed on a properly constructed, square,
flat and level foundation, as described below, is required. Without a properly constructed,
square, flat and level foundation, settling will eventually occur, causing distortion and damage
to the shed. Suncast is not responsible for replacing parts damaged or property lost due to
incorrect foundation construction. Warranty requires a properly constructed foundation as
described below.
• Complete the site preparation and foundation construction before unpacking parts and
beginning assembly. For tips on site preparation, go to www.suncast.com, consult retailer,
or local codes.
Site Preparation
1. Consult your local authorities for building codes and covenants before beginning foundation or erecting shed.
2. Before any digging, check with local utilities to determine location of buried cables, pipes, etc.
3. Decide which type of foundation is most suitable for your installation. The foundation surface must be square, flat and level.
Follow the below guidelines for foundation options:
Concrete Slab
•
Construct a slab of at least 4" thickness.
•
The use of reinforcement bar is recommended.
4. Complete the foundation preparations as follows:
•
A vapor barrier may be applied over the foundation to prevent excessive condensation in the shed.
Follow local building codes for a proper vapor barrier.
•
The ground should slope away from the foundation area to provide drainage.
Anchoring the Floor Panels to the Foundation
•
Shed floor panels include flattened areas where anchors or lag screws are to be secured.
These flat areas must be drilled through prior to securing the floor panels to the foundation.
Concrete Slab
•
Secure shed to concrete slab using 3/8" masonry anchors
with 1" washers. Masonry anchors and 1" washers are avail-
able at most local hardware retailers. 4 masonry anchors
are required for the Suncast BMS4780 Shed.

Note: Shed floor fastening locations are designed to align with
the under-structure layout. Be sure the front of the base panels
are oriented correctly on the platform to ensure lag bolts
engage with the under-structure.
