Spectrum’s seasoned team delivers unmatched expertise in the planning of your project.

Project preparedness is the foundation of pre-construction. Our project team begins by evaluating logistics, scheduling and buildability to eliminate any potential obstacles. By addressing these details early on, we can help other stakeholders understand the process and any changes needed prior to finalizing a plan. Spectrum’s pre-construction services can include design meetings, site visits, code review, preliminary pricing, value engineering, scheduling and product assessment.

Estimates & Budgets

Spectrum’s attention to detail in our budgets allows our clients to make informed decisions.

One of the most crucial components in the pre-construction phase is cost estimating. A successful project is one that is both on time and on budget; we take pride in our ability to work with architects, designers and end users to meet and exceed these goals. Spectrum stands out in the detail we provide in our estimates, which allows our clients to make informed decisions.


Spectrum understands the client’s design-build goals as a viable means of saving time, money and ensuring a high level of quality.

The design-build process provides an integrated approach that focuses on the client’s unique needs by combining the function of an architect, engineer and construction manager into a single entity. All responsibility and crucial information is are delegated to our project team. Our goal is to alleviate the stress from our client’s day-to-day, by having all the necessary materials prior to construction. Spectrum’s sole accountability reduces the risk of uncoordinated design, engineering, cost and schedule.

Project Management

We strive to deliver every project on-time and on budget without sacrificing quality. Clients benefit from our project managers’ comprehensive field and hands-on experience, guided by values of integrity, compassion and unsurpassed work ethic. Spectrum acknowledges that one size does not fit all. It is our priority to define each client’s distinct vision and tailor our approach accordingly. Spectrum also utilizes secure, digital tools such as Microsoft Project Scheduling and Red Team to allow timely and proactive communication. Spectrum values the long-lasting relationships we have built with our clients over the years and maintains continuous contact even after project completion.

At Spectrum superior customer satisfaction, precision, and cost-effective solutions are the heart of project management.

Noticeably Different


Sustainability is the focus in everything we do.

However, we recognize the importance of applying Leadership in Energy and Environmental Design (LEED), green building, and sustainable construction. Our team is educated in sustainable processes, always ensuring that certification goals are met and standards are maintained.
