shelby joubertShelby Joubert 
Project Manager, Swinerton

Shelby Joubert is a Project Manager at Swinerton, a 131-year-old construction company with Bay Area roots since 1900. She has more than 15 years of industry experience starting her career in Southern California with a structural concrete company prior to making the transition to the general contractor side of construction for the past 11 years. In her role as a project manager at Swinerton, Shelby manages new construction projects from the design and development phase through end of construction. Shelby’s most recent projects in the Bay Area include LEED Platinum office 333 Brannan and award-winning residential projects 399 Fremont and 288 Pacific. Her experience in exterior facade construction consists of a wide range of systems, including unitized curtain wall, window wall, precast panels, rainscreen, and masonry facades. On her most recent project, 288 Pacific, Shelby’s guidance and continued leadership led to successfully coordinating and constructing multiple exterior facade systems, resulting in zero performance and quality issues after construction. During this process, her thorough understanding of multiple subcontractor trade-specific scopes helped resolve critical installation and performance issues that commonly are overlooked. Bringing these items to the forefront during the exterior facade preconstruction and testing phase helped alleviate financial, quality, and schedule impacts that commonly occur in the aggressive construction market in San Francisco.

Tyler Westerling joined Intertek in 2003 after graduating from the engineering program at San Francisco State. His focus in school was on thermodynamics and fluids, so he began work in the testing of fenestration products for the National Fenestration Rating Council certification program, primarily focused on U-factor testing. Intertek designed and developed the industry’s first accredited solar calorimeter (NFRC 201) and Tyler became involved with the development and improvements of this test equipment. Soon, he developed the first accredited test apparatus for Visible Light Transmittance of translucent sheet material (NFRC 202) and then Tubular Daylighting Devices (NFRC 203). From there, Tyler’s focus became air, water, structural, thermal, and seismic testing of full-size mock-ups at Intertek Fresno’s newly built mock-up facility (2008), which included a 280-foot-long mock-up facility with the capacity for eight or more mock-ups at a time. Soon, 120 more feet of capacity was added for testing shorter products such as doors for Dade County hurricane impact certification. Some of his notable mock-up projects include the New Stanford Hospital, Apple Campus Theater, Amazon Spheres, Anaheim Regional Transportation Intermodal Center, and the new Golden State Warriors Stadium (Chase Center).
