Site Preparation and Platform Construction
Materials NOT supplied with BMS7425 Shed Kit
Note: Site preparation is required for this shed. Placing the shed on a constructed foundation is required. Without
a constructed foundation, settling will probably occur, causing distortion and damage to the shed. Suncast is not
responsible for replacing parts damaged or property lost due to incorrect assembly. Warranty requires foundation.
Note: 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 code.
To prepare your shed site, follow the below steps:
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 you want:
- Concrete slab, 4" thick
OR
- Wood platform
Use exterior grade wood. The wood platform should be set on pier blocks or footing. Consult your local retailer for
help to determine the best anchoring method for your particular installation. The provided plans are sized for the
minimum number of cuts to lumber and plywood.
4) Prepare the building site:
- The ground should slope away from the foundation area to provide drainage.
- The foundation surface must be flat and level.
- A vapor barrier should be provided to prevent excessive condensation in the shed.
- Follow local building codes for a proper vapor barrier.
5) Anchoring the shed to the foundation:
- Consult your local retailer for help to determine the best anchoring method for your particular installation.
- To secure the shed to a concrete slab, use masonry fasteners available at your local hardware retailer.
- To secure the shed to a wood platform, use 1/4" x 3" long lag screws with washers.
