Fair Pricing

To provide our clients with reliable quotes and peace of mind, we calculate the majority of our estimates based on square footage rather than an hourly rate.

Technological Efficiency

Leveraging today's collaborative and information-sharing technology in our daily work is just one way we provide efficiency to our clients. In addition to cloud computing, special and custom applications, and video conferencing, we also employ the following methods to optimize our processes:

  • Client Cloud Access & FTP Portal – Provides real-time access to plans progressions
  • Paperless Construction Documents – Reduces amount of documentation and increases on-site mobility (i.e., tablets) and accuracy
  • Electronic Documentation & Cloud Storage – Convenient access to our calculations, drawings, and records
  • Electronic Invoicing – Hassle-free cost tracking
