Services Provided by KSA Include:
Civil Engineering

We provide civil, mechanical and electrical engineering services for community facilities, such as water and wastewater treatment plants, street and drainage improvements and recreational facilities. We commonly assist cities with the development of capital improvement plans for infrastructure needs. We utilize all our resources to provide long-term, functional solutions.

  • MEP

KSA provides architectural design services to local, state, and federal agencies and a variety of institutions, including K-12 and higher education, airports, recreational facilities and event venues.


KSA’s Aviation Services group has a holistic approach to aviation engineering. We take on each project with future projects in mind, thereby ensuring our clients are always prepared for their next need or development opportunity. Our staff  has completed aviation projects for airports across the southwest region, ranging in size from small general aviation airports to medium hub commercial service airports. 


Surveying, which is often the first course of action before design starts, establishes land boundaries and topography. KSA utilizes the latest technological advances to provide accuracy in survey measurement and to ensure that the designs are compatible with the environmental and topographical conditions of the communities we serve.

  • GIS
Alternative Project Delivery

KSA provides turn-key project delivery through multiple delivery methods. From concept through completion with a single contract, we leverage strategic partnerships with qualified contractors and our subsidiary BLOC Design-Build, LLC., to deliver projects in the most cost-effective manner. 


Experience with major drainage projects, coupled with the latest computer technology, enables KSA to design and implement innovative drainage solutions. We have in-depth knowledge of Federal Emergency Management Association (FEMA) procedures for letters of map revision (LOMR) and conditional letters of map revision (CLOMR) coordination. Our use of hydrology and hydraulics (H&H) modeling programs allows us to confirm impact of drainage modifications to sensitive sites and design sustainable drainage solutions.  

Mechanical, Electrical and Plumbing

Our electrical engineers, master electricians and instrumentation technicians design automation and remote monitoring systems for municipalities, airports, manufacturers, and the oil and gas industry. Our electrical services include design, installation, maintenance and troubleshooting electrical wiring systems to power facilities of varying sizes. We custom-build and program supervisory control and data acquisition (SCADA) systems to maximize operating performance. KSA does not provide plumbing services for development projects. If plumbing services are needed in conjunction with municipal projects KSA will partner with an appropriate sub-consultant.

Streets and Roads

Transportation systems like roadways, highways, toll facilities, bridges and water resources play a huge role in our ability to go about our everyday lives – both work and play. At the core, we are committed to improving trip safety and quality for the traveling public. We have extensive experience in street and road development and improvements and we work with municipalities and state agencies for street assessments, safe streets programs, capital improvement plans, street reconstruction and extension design and other street-related services like stormwater pollution prevention planning (SW3P) and signage, striping, and traffic control. 

Water and Wastewater

Adequate water supply and wastewater treatment capacity are always critical components of a city’s ability to grow. KSA serves both public and private sector clients in the areas of water and wastewater treatment, water transmission and distribution and wastewater collection systems. We specialize in the modification of existing water and wastewater treatment plants to meet evolving national, state and local treatment standards. Our staff  perform all facets of permitting, treatability studies, design, construction administration and operational training.
