About the Session

DBIA San Antonio Chapter's Chair Aron Soto of MGC Contractors will give the following presentation at the 2023 Texas Water Conference:

"Using Progressive Design-Build in a Volatile Market from an Owner and Design Builder Perspective"

The San Antonio River Authority (River Authority) used progressive design-build delivery for the Salitrillo Wastewater Treatment Plant (WWTP) Expansion Project, which expanded the plant from a capacity of 5.83 millions gallons per day (MGD) to 7.33 MGD. This delivery method was new for the River Authority, and it quickly became an effective but challenging way to manage schedule and cost in a new virtual environment.

The RFQ was issued January 8, 2020, after which the qualified design-build teams were shortlisted. An RFP was then issued on March 16, 2020, the same day San Antonio’s mayor issued an emergency declaration urging the public to avoid gatherings of 10 or more people. Along with the new challenge of collaborating in a totally virtual environment, there were issues during construction with cost escalation and material delays that tested the flexibility of progressive design-build delivery.

This presentation will discuss the following from both an owner’s and design-builder’s perspective:

  • The procurement process and associated challenges and solutions

  • Best contracting practices in a volatile construction market

  • Project management lessons learned

  • Managing constant fluctuations in raw material and equipment costs during pre-construction and construction phase

  • Pros and cons of using progressive design-build, and recommendations for using this method in the current market
