Proposed Inspector Matrix
All our proposed Multi-Carded Inspectors are familiar with overseeing projects across Southern California. Their accumulated expertise will be a valuable addition to the team, contributing by conducting thorough testing and inspections. They will maintain communication with the City's project management staff and collaborate seamlessly with the professional team.

SECTION B: QUALIFICATIONS OF CONSULTANT TEAM
Twining | City of Santa Clarita - The Rinks 11
Most of our inspectors and technicians carry multiple certifications for various disciplines of work. We have demonstrated in the past that we use inspectors and technicians that can overlap disciplines on the project which saves on the inspection and testing budget. For example, Twining will provide a technician/inspector that covers geotechnical and concrete aspects of the project when both those disciplines are present at the job, provided each can be performed to the satisfaction of the Building Code and meet the project needs.

Project Management
Project Manager, Jeff Tawakoli, PE, will serve as the primary point of contact with the City. All of our services will be seamlessly coordinated by Jeff and communicated to the City without delay. As our designated point of con- tact, Jeff will oversee all services provided by Twining and verify the City has the necessary resources to respond to each task assignment. He will be familiar with each assignment and will work closely with the City's project manager to ensure all project needs are met and the City is completely satisfied with every aspect of Twining’s performance.

Jeff will review all invoices and reports prior to their issuance and will guarantee the accuracy and timeliness of all. He will be available to the project team members to answer questions or make suggestions, will keep the City informed of budget status, will work with the project team to reduce costs, and will support the delivery of our services in an efficient manner.
