Economize with Efficiency.

Design better buildings with smart, safe, and cost-effective post-tensioned and reinforced concrete expertise.

As concrete structures become more complex with specialized demands, the use of post-tensioning is becoming more common. Post-tensioned and prestressed concrete building design is ever-changing and largely driven by safety, economy, and efficiency while meeting aggressive design demands. By combining PT design expertise and an intimate knowledge of 2D and 3D Finite Element Analysis software modeling and analysis tools, let PT-Structures elevate your post-tensioned and reinforced concrete design needs.

What We Do

Analysis & Design

Let us assist you with designated analysis and design services for post-tensioned concrete structures. This is our focus and expertise. We strive in delivering efficient and economical designs and rely on extensive experience in a diverse range of project and design applications.

These Include:

  • New design of post-tensioned and reinforced concrete systems including but not limited to: One- and two-way flat slabs and plates, waffle slabs, beam-frames, specialized PT walls, beams, joists, girders and transfer elements.
  • Reinforced and post-tensioned concrete structural mat foundations, industrial slabs, slabs-on-grade, pad and continuous footings.
  • Forensic evaluation and investigation of existing reinforced and post-tensioned concrete systems for retrofitted loads and application or repair and capacity evaluation.
  • Third-party peer review services
  • Value engineering of reinforced and post-tensioned concrete systems for alternate cost analysis and projection.
  • Lateral system analysis and design for shearwall and concrete moment frames with consideration of secondary actions due to post-tensioning.

PT-Structures continues ADAPT’s long-standing tradition of providing specialized engineering services for the design and investigation of post-tensioned structures. After ADAPT’s software division joined RISA in early 2020, the core consulting team continued its activities as PT-Structures. With our deep expertise in the design of post-tensioned structures and an intimate knowledge of ADAPT software, we are uniquely positioned to provide a wide range of expert design, investigation and modeling support services.

We have extensive experience working on post-tensioned projects that span the world. We have collaborated with the largest global engineering firms on the most challenging and innovative implementations of post-tensioning, helped contractors achieve significant savings through value engineering, and worked hand-in-hand with sole proprietors on their first post-tensioned projects. No project is too complex or small. We have seen it all and thrive on enabling our clients to create great projects.

We have designed millions of square feet of both bonded and unbonded systems, in compliance with all major building codes. Contact us to find out how we can help you on your next post-tensioned project.

A practicing structural engineer, Dr. Bijan Aalami, Professor Emeritus of Civil Engineering at San Francisco State University, is an internationally renowned educationalist and leader in the analysis and design of concrete structures with specialization in post-tensioning. A native of Iran, he graduated from University of London (Imperial College), held positions as professor and Vice-Chancellor of Arya-Mehr (now Sharif) University, followed by appointment as professor of Civil Engineering at San Francisco State University.

Professor Bijan has made decisive contributions to the understanding, behavior and design of post-tensioned buildings and bridges. Bijan was recognized as the first Life Member of the Post-Tensioning Institute, for his decades of contribution to the post-tensioning industry. A member of the former Imperial Academy of Sciences in Iran, a Life Member of ASCE; honorary member of the Argentine Institute of Structural Engineers, he has been holding educational courses on design of concrete buildings and bridges throughout the United States, Canada and over 42 other countries worldwide.

Bijan is a Chartered Engineer in the UK, and a registered Structural Engineer in California. He received the American Concrete Institute’s Design Award for the “application of advanced engineering to a notable concrete structure.” In 2003, Bijan’s contribution to the industry was recognized through his initiation in the Hall of Fame of the Post-Tensioning Institute.

As Founder of ADAPT Corporation, Bijan has been actively engaged for over 35 years in the design and construction of numerous concrete buildings, bridges and special structures, in particular post-tensioning. A renowned world leader and teacher, Bijan has enriched the practice of thousands of engineers in North and Latin America, Far East, Europe and the Middle East. His extensive publications on concrete design, in particular post-tensioning, are a treasured resource for practical design of conventionally reinforced or post-tensioned buildings and bridges.

"The PTS team, formerly ADAPT Consulting, has been a business partner for over 15 years having worked together on a multitude of strategic and challenging projects in the Middle East during my tenure at Freyssinet. The relationship with ADAPT Consulting initially began by outsourcing design and engineering services but it quickly evolved and matured making them an integral part of our operations. The PTS team played a pivotal role in the successful development and promotion of the post-tensioning technology which ultimately led us to become the benchmark for post-tensioned applications in high rise buildings. They continued to offer unparalleled support during my recent stint with Freyssinet in Canada. Together we worked tirelessly to offer value engineered solutions and promote post-tensioned applications in the construction market. I have recently embarked on a new venture with 'e.construct' to manage and lead special construction projects and I look forward to replicating and progressing my collaboration with the PTS team further."
