New Structures

Mellor Engineering has designed extensive experience in the design of new building structures to meet the ever increasing demands of current applicable building codes. New building can be made out of a variety of materials, such as Concrete, Concrete Masonry Unit (CMU), wood, structural steel, light gage steel, aluminum and Fiber Reinforced Polymer (FRP), structural glass and any combination of these materials. Mellor Engineering can ensure that a robust, dependable, code compliant engineering design is provided.

Existing Structures

Mellor Engineering has performed structural engineering services for existing commercial property improvements which require a building to be altered to accommodate new uses which differ from the original design and construction. All existing structures are different from new buildings and they require an added attention to detail to minimize unnecessary costs. Mellor Engineering has vast experience in providing the component specific detailing required for existing structure projects.


Residential remodels and custom home construction are some of the most inspiring and complex projects out there. Increasing demands for open floor plans in residential construction requires creativity in the engineering design. We strive to accommodate the demands of many complex residential configurations.

Historic Buildings

Mellor Engineering has extensive experience with the evaluation and repair of old and historic buildings. Our extensive experience with historical buildings includes engineering evaluation and seismic upgrade design for unreinforced masonry buildings, concrete buildings and wood framed buildings. By repairing and upgrading older buildings, we are preserving the past. Mellor Engineering can help bring your older existing building into the future with the design of any necessary structural repairs and seismic upgrades.

Tenant Improvement

We provide structural design for commercial tenant improvements in large retail facilities and individual buildings. Commercial retail projects include restaurants, coffee shops and retail sales stores. Structural modifications are sometimes required and Mellor Engineering can work with building owners and contractors to work through solutions to tough problems; such as evaluation existing structural components for added equipment loads, raising entire floor systems weighing 30,000 pounds or more, and cutting large holes in existing roof systems.
