Testimonials
Our Testimonials
-
Do I need both an architect and a structural engineer for my project?
For the most part, yes. An architect determines the design and flow of the house; the structural engineer ensures its stability and security. To have them both from the start gives you better coordination and fewer headaches down the road.
-
What is the difference between architectural design and structural engineering?
The architectural design relates to shape, function, and building code compliance. Structural engineering involves the study of load paths, materials, foundations, and safety. The outcomes of both are required for the execution of a project.
-
Can one company provide both architectural and structural engineering services?
Yes, absolutely. Plansing offers fully integrated architectural and structural engineering services; our team ensures that drawings and calculations are aligned and approved more efficiently.
-
When do structural calculations become necessary in a design project?
When making changes to load-bearing walls or installing RSJ beams, or for foundation alterations or property extensions, structural calculations must be submitted to building control for approval.
-
Why is it beneficial to combine architectural design and structural engineering from the beginning?
Early integration reduces redesigns, improves structural efficiency, speeds up approvals, and lowers construction risk, saving time and money.
