QK has been a leading provider of engineering, land surveying, planning, and environmental services to California public agencies for nearly 50 years. Our One Connected Team philosophy is designed to help cities, counties, water, wastewater, and special districts, by offering a broad range of comprehensive services, strategically interwoven to make project delivery nearly seamless.

We also help many of our public agency clients as contract City or District Engineer and/or Surveyor. In these roles, our staff becomes an extension of City/District staff as needed. As a result, these clients gain access not only to their designated Engineer or Surveyor but a support staff of more than 100 licensed and technical support staff.


Client Experience


In working with QK, I have found their staff to be knowledgeable, responsive, and possess a solid working knowledge of engineering and of the overall project development process. I especially want to commend their focus on emphasizing teamwork and collaboration between TCAG, their client agencies and Caltrans project representatives and their respect for communication and contractual obligations.

QK staff performed the requested scope of work within the agreed upon timeframe and within budget. Their staff was competent, professional, and worked well with County staff. Prior to the project, the County had been skeptical of the results of drone survey due to the previous consultants’ work. QK was mindful of this and worked to keep County staff apprised and comfortable with the methods and technologies used in their work. The County was very pleased with the finished product.
