7 Frequently Asked Questions About Engineer Plans

What information do I need for engineer plans?

Most companies just need the customer to confirm the locations of doors, openings, and specific building measurements. Any changes to the plans may result in extra charges based on the engineer’s time. 

What are the two types of engineer plans?

  • Generic engineer plans: These drawings cover standard dimensions up to 30′ wide and up to 12′ tall. Generic plans show a general placement of any garage door opening, service doors and windows included on your building. 
  • Custom engineer plans: These plans are for more complex buildings. Engineers specifically make plan designs to break down the components the building will require. Custom plans are typically required for construction on wide spans (over 31′ wide & higher than a 12′ leg), or when required by a building department. Engineers create custom plans per order and are specific to every project!

Standard Roof

Standard or known as “Regular” roof style have rounded corners. The regular roof has no trim on your eaves, ridge cap, nor purlins (hat channel) making it cost effective option. Standard roofs are best used in areas that experience fair weather year round.


A-Frame Horizontal Roof

A-Frame Horizontal roofs give your structure a residential look. The sheet panels run from side to side and does not have purlins or ridge cap. The increase in price to upgrade to A-Frame Horizontal is the additional welding needed on your trusses (bows). An excellent option to keep your residential look for residential areas for a minimum upgrade costs.


A-Frame Vertical Roof

Known as the best choice for areas that experience extreme weather conditions, the vertical roof style is hands down the best choice for Michigan weather. The roof panels run from the pitch to the eaves causing heavy snows, rain, and natural elements to slide off the roof easily. In order to tie down the panels to the structure, we must add purlins or hat channels lengthwise making the structure more rigid. The finished look with special trim all around the roof and ridge cap makes this roof style the best option.
