Accessory Structures

The engineering scope depends on the structure's size, use, construction and site conditions. Manufacturer drawings can be a useful starting point, but the foundation and anchorage still need to suit the project.

An engineer may be needed for a custom structure, site-specific support details or questions raised during review of a prefabricated building.

Confirm the engineering scope with the professional you engage and any permit requirements with the local building department.

Topics that may be relevant to the review: awning, billboard, bollard, canopy, chain-link fence and dumpster enclosure.

The engineer can review existing conditions, evaluate the proposed changes and prepare the calculations or design details included in the agreed scope.

• Designing support for a backyard workshop
• Adapting a prefabricated structure to the property

Start with a short description. These details can help define the scope, but you do not need everything ready to request a quote.

• The project city or county, and the property address if known
• What you want to build, change or repair
• How the space or site is used now and what you plan to change
