Residential and commercial projects will differ in some aspects. However, they will usually have the
basic phases of service in common. These basic phases include: 1. Pre-Design 2. Design 3.Construction
Documents 4. Bidding/Negotiation 5. Construction Services.
Remodels, additions and tenant improvement projects will require existing facility / building plans or
record drawings. These record drawings will be assembled durring the Pre-Design phase of services.
You may have access to these plans or they may have to be compiled through a combination of
research , field measurements and drafting. The information compiled will be drafted into record
drawings using our CADD software. The record drawings will be used as a bases for design.

recommend professionals that we have worked with on past projects or we can work with
professionals that you select. We can also provide the structural design, mechanical design, electrical
design and energy calculations. More complex projects can require a vast array of professional
consultants we can recommend or work with your selected professionals.
