Stormwater Drainage Design

Prevent on-site flooding and ensure local compliance with professionally designed stormwater systems. We analyze runoff patterns and develop drainage plans that protect your property and infrastructure.

Grading Plans

Establish the right foundation for your project. Our grading plans help manage slope, support proper drainage, and align with building requirements - minimizing costly changes during construction.

Erosion & Sediment Control

Maintain environmental compliance and site integrity. We create effective erosion control plans that reduce runoff, protect surrounding land, and meet city or county permitting standards.

Earthwork & Cut/Fill Calculations

We provide precise cut and fill analysis and earthwork calculations to balance grading, reduce hauling costs, and optimize site preparation. If site plans are not yet available, we can refer you to trusted architectural partners to help get your project started.

Utility Connections

Civil engineering design and coordination of site utilities--including water, sewer, storm, gas, and electrical--ensuring proper routing, code compliance, and integration with site grading plans.

Structural Engineering

We provide structural plans and calculations for both residential and commercial projects. From foundation design to load-bearing walls, our licensed engineers deliver permit-ready structural engineering for your development.

SUCCESS STORIES

What Our Clients Are Saying

See why homeowners and industry professionals across Washington trust us with their projects.

"ProStruct Engineering prepared the structural plans for my home remodel, which required extensive consideration due to the age of my house and its location near the beach. Nithin, the project manager, was incredibly responsive, quickly facilitating changes requested by the city during the review cycles. Their expertise and willingness to consult throughout the construction process will be invaluable. I'm genuinely grateful for their professionalism and support."

Sandra

"The engineer checked thoroughly for issues related to our foundation. He gave unbiased opinion and very constructive recommendations to mitigate the issues. Compared to the sales person from various foundation contractors, this advise would help us avoid the over engineering and save more than $30k."

ZF Zhan

"Prostruct was great! Responsive, prompt, great communication. I am looking forward to going into the permitting process with them since I know to expect good results and communication."

Vatche Bezdikian

"I just received notice that I will now have my permit to build a bathroom and bedroom as a remodel in my garage. Josh was great and Nithin and his team helped me through the process. YAY!"

Dee Sherm

"The PM was prompt and the engineer that came to assess structure was courteous. He was able to give us a report including all the details he discussed with us in person. The PM is knowledgeable of the general construction process as well. Would definitely send business their way again, should a structural assessment need arise again."

Hiren Patel

"We contracted ProStruct to look at the integrity of some retaining walls. Nithin, Josh, and Jesse were swift with their communication and very knowledgeable. We will be using them again in the future!"

Wade

"Easy process! Great communication every step and the inspector was able to come out and inspect our foundation very quickly. Overall impressive company who I would recommend!!"

Tamara Lee
