Design BuildDesign-Build

Septagon’s Design-Build construction process allows the clients to work with one company throughout the entire construction process. We provide construction services while helping the client select the best design services to fit the needs and style of the facility.

This means, we assemble the best architect, engineer, and interior designer that will best fit the project and guide the client though the myriad of choices that arise over the course of the construction process. We will show you the best route when navigating questions like: “Which location and site is best? How do I best use the site I have? How much building can I afford? Can I improve the look and stay under budget?”

Septagon Construction’s design-build team will deliver on  your expectations and determine the essential issues to create your idea facility.


General ContractingGeneral Contracting

Septagon is successfully awarded General Contracting projects on a high percentage of our bids each year, and we enjoy a great reputation with the design professionals in our region.

Conventional General Contracting is a time-tested method of construction, where completed construction documents are required prior to setting a price for your project.

Typically, the selection of the General Contractor is based on a price derived from competitively bid or negotiated subcontractor bids.

The contractor is responsible for construction, schedule, selection of subs and suppliers, and safety.  The architect prepares the plans and serves as an agent of the Owner but usually has no construction budget responsibility.

Regardless of the process used to select Septagon, our clients are assured the highest level of professionalism, experienced supervision, construction quality, and safety on their project.

Construction Management
Construction Management

The system of Construction Management assures the Owner of cost efficiency, quality control, and professional representation of the Owner’s best interest.  In short, Septagon’s Construction Management service is designed to complement and enhance the services of the architect.

With our roots as a self-performance general contractor and as a successful design-build contractor, Septagon’s Construction Managers are in a position to fully understand and address any challenge that may come our way.

As either a Construction Manager serving as your agent, which is particularly beneficial for public sector jobs, or as a Construction Manager with a shared risk in the critical elements of the projects, our clients receive the most professional representation available through the Construction Management process.

A leaking roof can damage your inventory, halt production and diminish your profits. Short-term fixes never seem to solve the problem.  Respond to these situations with a long-term, best value roof solution from Septagon.

With our thermal imaging capabilities, we can perform a complete evaluation of your roof system to pin point areas that need immediate attention or routine preventative maintenance. This information comes to you in the form of infrared images, photographs and core cuts all compiled in a report.

Septagon’s roof solutions offer reduced heating and cooling costs compared to conventional roofing materials and are virtually maintenance free. The systems also help you meet LEED and ENERGY STAR Cool Roof standards.

So, regardless if you have a leaky flat roof, metal roof or membrane roof, Septagon can find the best value Roof Solution to fit your budget.
