DSA Support



1. DSA projects closed without certification may impact the processing of subsequent projects resulting in expensive delays.

2. DSA closeout requirements present many challenging conditions. For instance, incomplete documentation is often submitted which can cause time-consuming re-submittals.

3. DSA provides a web-based tracking system to assist in monitoring the status of projects. However, due to a large amount of data submitted in conjunction with recent DSA employee furloughs, the information is often not current, which compels the need for additional costly research.



1. A key to obtaining final DSA certification is to ensure that all required documents for submission are complete and signed by the right governing parties, organized and properly submitted to DSA.

2. With a thorough understanding of DSA requirements, SKC Company professionals take a proactive role to obtain DSA certification in a timely manner.

3. SKC has developed a close working relationship with DSA personnel including field engineers and inspectors. These connections are beneficial when it comes to expediting the process.



1. SKC handles all manners of closeout issues and has solid procedures in place to monitor and accelerate the process for closeout certification.

2. SKC closeout specialists have overcome many challenges by establishing comprehensive documentation with all governing agencies.

“During the past several years, I have had the pleasure of working with Sean Khan with SKC COMPANY on numerous school construction projects in which they served as the general contractor. Most recently, SKC COMPANY is working with our firm on a multi-million- dollar Science Classroom Complex for the Mt. San Jacinto Community College District. I am impressed with the firm’s ability to understand the construction process especially as it relates to school projects. This is an especially challenging project due to having to meet a very stringent construction schedule. They have demonstrated their ability to work with architects, owners, inspectors and testing labs to assure timely completion of the projects they have supervised.”

I am writing this letter to recommend SKC Company as a modular classroom building contractor. While acting as a consultant to SKC Company since 2012, I have found Sean Khan to be very experienced and very knowledgeable in the modular classroom industry. It has been my experience that Sean Khan possess a sound understanding of the design, permitting, installation and inspection processes associated with this type of project. In summary, I heartily recommend SKC Company for any modular educational project.
