It also offers such services as building performance assessment, repair and rehabilitation, building and infrastructure sustainability, failure investigation, materials consulting, nonde- structive testing, structural engineering and evaluation and mass concrete consulting. Structural health monitoring (SHM) is “a growing business for us. We do work on projects that involve what I would call remote sensing – using advanced digital technology to assess the behavior of a structure or the materials in a structure. That can involve using sensors and digital technology to measure movement, deflection, vibration of structures. We’re also involved with evaluating moisture content and moisture movement in concrete – how that affects durability and service life,” adds CTLGroup Chief Operating Officer Tim Tonyan. CTLGroup’s services are all-inclusive. “We provide expertise and consulting services through the full life cycle of the building “CTLGroup performs or infrastructure facility, meaning that we help with conceptual materials testing at a planning, we help with the detailed design, we help during the con- series of labs located struction process, and then we help or we assist clients through the life in Skokie.” cycle of the facility itself,” says Tonyan.
