Dependable, accurate, responsive, value, thorough, comprehensive, reliable, timely, are only a few adjectives that describe John and his teams work. His company provides an invaluable independent third party’s perspective on plan quantities and costs. I am such a fan of John's company I brought his services to Colorado!

Rick Dengler - President Brookfield Residential

John Jordan and his team have been a trusted addition to TDS’ estimating department for nearly 15 years and part of my team for well over 20. Whether it was feasibility studies, value engineering or take-off to help us keep up with the hectic residential market, John’s team has always delivered. His accuracy and timeliness is been beyond reproach.

Thank you SDS for always filling the gap.

For many years we have used SDS for their takeoff services. When we’re in a bind for an earthwork takeoff I know that we can trust SDS for their detailed earthwork analysis. They have proven to be a great resource for us.

Dave Speed - VP William A. Hazel, Inc.

I have had good results using SDS. I have found that besides just balancing the surface volume having your firm include the spoils in the underground utilities and on select sites having you determine the volume of each type of soil from the borings can mitigate the amount of import/export and reduce costs.

John Jordan and SDS has been providing construction estimating services for Urban and our clients for more than 15 years. With John’s deep experience in construction prior to starting his business and his teams additional talents in estimating and evaluating construction for highly complex projects in a very competitive market, I would not turn to any other estimating consultant or recommend anyone to my clients, then SDS. I have worked with SDS on value engineering, budgeting, predevelopment planning, and expert witness testimony over the years and I hope to continue this great relationship. What I like most about SDS is that John is a hands on principle and he assures that his expertise is involved in every project.
