With California’s ever changing fiscal situation, aging infrastructure and continued urban growth, our cities and counties are faced with unique challenges. It’s crucial for public agencies to stretch their dollars spent to maximize the community’s investment. Our Quality Assurance Programs are used by numerous agencies throughout the state and emphasize the most cost-effective practices.

We are uniquely positioned to provide quality assurance programs from start to finish. Through our partnerships with Caltrans and various research institutes, we have knowledge of proven technological advances in construction that we can pass on to our clients and incorporate in their projects as appropriate. We routinely contribute to the American Public Works Association by presenting technical sessions related to some of the newest technological advances. Whether it involves rapid strength concrete, warm mix asphalt, high volume fly ash mixes to reduce greenhouse gases, or 100% recycled materials, Twining can provide the proper solution for your project.

Whether it is a major water/wastewater project, bridge and roadway improvement, underground utility work, or airport improvement project, our team possesses the requisite expertise and capabilities to effectively establish and maintain a quality assurance program that is in strict compliance with the local assistance procedures manual as well as state and federal mandates.

Twining employs project managers, registered civil and geotechnical engineers, all of whom are experienced in public works quality assurance. Each engineer is fully responsible for the project that they manage which creates a seamless flow of engineering recommendations, inspection reports and laboratory reports. We maintain a project management approach that utilizes electronic inspection reporting where possible and appropriate.

Our team of engineers and project managers are supported by a deep roster of field inspectors that practice a proactive inspection approach. This means that they are arriving to the site prepared, providing proper documentation, and communicating frequently with the project management and project stakeholders. Our inspectors understand what is expected by our clients. When a non-compliance issue has been determined to exist, it is communicated to the project  team and followed from the moment of occurrence and until it is reconciled.

Twining provides the following services for local agencies:
