Preconstruction & Design

Bringing in experts early on a restoration project is key to success. With Spectra’s PRECONSTRUCTION AND DESIGN services, many items (such as changes due to discovery of existing conditions for construction feasibility) can be mitigated early in the project, resulting in a more cost-effective, timely completion. With over 30 years of experience in historic construction and preservation architecture, Spectra Company’s construction and architecture team is uniquely qualified to operate as a collaborative partner in the preconstruction phase for ensuring a successful historic rehabilitation.
