Fig. 8: Aerial view of near-complete Marina Heights (State Farm) development (January 2017) control joints were implemented in our shotcrete installation. A wood float finish followed by a light broom drag was selected as the final shotcrete wall finish. Buesing met or exceeded the requirements and expectations of the 6000 psi (40 MPa) design mixture, the quality control testing, finish, and schedule. The shotcrete scope(s) that we performed on this project was intense, working alongside a robust concrete operation by Suntec that included multiple tower cranes and a steady stream of concrete ready-mix deliveries. All in all, the project was successful because of early and effective planning, and hard work by our employees on the project, certainly inclusive of the shotcrete crew. About the Company Buesing Corporation is a Phoenix-based construction Kevin Somerville graduated from Arizona State University in the construction management program in 1990 and immediately began a career at Dames & Moore that later merged with URS, both of which are international engineering/geotechnical/ consulting/environmental firms.

Somerville became Vice President of Estimating & Business Development/Marketing in 2005. Last year, Bill Kelton joined the company as VP of the estimating department, and Somerville is currently VP of Business Development/ Marketing, while still an integral part of estimating. temporary shotcrete shoring facing system. The shoring served as the back form for the perimeter finish wall in most cases, and there was also back forming required to be installed by Suntec above our shoring to achieve design elevations around the perimeter. The perimeter finish wall design included horizontal corbels and notches for the intermediate floor. All columns were designed away from the perimeter so there were no pilasters (in-wall columns). The shotcrete installed, met, or exceeded the 6000 psi (40 MPa) design requirement. Both construction joints and scored contractor that performs a variety of civil and site work services for multiple markets. It has served the construction industry since 1965, beginning in Minnesota, and moving to Arizona in 1986. It owns a wide variety of equipment that is well maintained at the company’s shop or by two shifts of mobile mechanics. Buesing works on many high-profile projects and for some of the largest developers and general contractors. Although shotcrete is a fraction of their business, they have become a leader in the market, providing shotcrete services for the construction and shoring projects they are awarded, as well as an ancillary service. For years, one of the company’s successful formulas has been to self-perform mass excavation, shoring (earth retention), and shotcrete finish or structural walls on numerous basements or below-grade garages in Phoenix and Tucson. www.shotcrete.org Spring 2017 | Shotcrete 59
