What we do

Owner’s Representatives

We manage the construction process to help reduce cost, shorten delivery times, and ensure quality craftsmanship. SPECTRE8 is the owner's advocate, overseeing the operations of contractors and designers to provide the confidence that your project will be completed successfully. 

Construction Managers

As construction managers, it is our role to act on the owner's behalf during the construction process.  Our construction expertise allows you to focus on your life while we focus on your project.

Project Managers

Finding an architect, dealing with the building department, and hiring a contractor are just the tip of the iceberg when it comes to your new project.  Very few homeowners have the expertise or the time to manage a construction project.  This is where we excel.  



A single point of contact to simplify project communication

We provide a centralized channel to ensure streamlined and organized communication throughout your project.  Our goal is to provide a new level of professionalism not typically found on most construction projects.


Accelerate the speed of your project through careful time management

A thorough understanding of the building trades and how they relate is essential to keeping a project on track.  SPECTRE8 is able to build and maintain strong relationships with the construction team to ensure every member is fulfilling their obligation to your project schedule.

Realize cost savings on your project

SPECTRE8 can reduce or eliminate many cost overruns and hidden charges that are commonly associated with construction projects. Through our years of experience, we can identify and eliminate these costs before the project even begins.  Change orders that arise during the course of the project can be minimized through careful negotiation and understanding of the construction process.

Continued service and maintenance after project completion

Our involvement with the owner does not end once the project is complete and our clients move in.  SPECTRE8 is there to assist with follow-up projects of any size; regular home maintenance, and warranty work.  We have helped clients select furniture, art, wine collections, and even cars.  Construction is a relationship based business, and it is our business to build and maintain these relationships.
