F O C U S F O C U S While DYWIDAG-Systems International (DSI) is best known for its array of post- tensioning and geotechnical products, its role as a specialty contractor has been growing. Now, with the addition of several high-tech companies, DSI intends to expand its prominence and market penetration as a service provider. New Scope of Services " We ' re n o l o n g e r j u s t t h e p o s t - t e n s i o n i n g p ro d u c t s u p p l i e r t h a t p e o p l e k n e w i n t h e p a s t , " s a y s Jason Caravello, director of business operations for DSI's Global Services b u s i n e s s u n i t i n N o r t h A m e r i c a . " F o r e x a m p l e , w e a re a c t i v e i n t h e i n s p e c t i o n , re s t o r a t i o n , a n d maintenance of parking structures, stadiums, high-rise buildings, tanks, a n d b r i d g e s . We a re e x p e r t s a t design-build structural-strengthening solutions, often utilizing a variety of systems, including post-tensioning or CFRP [carbon-fiber-reinforced polymer], and even coatings. We obviously use our products where they apply, but we do much more than that." 'We're no longer just the post-tensioning product supplier that people knew in the past.' Many recent changes at DSI began after Matti Kuivalainen was appointed chief executive officer of DSI Construction in the United States in September 2017. DSI Construction was split from DSI Underground the previous year by the Germany-based parent company DSI. In January 2018, the North American divisions were organized into the Global Services (contracting), Geotechnical, P o s t - Te n s i o n i n g , a n d C o n c r e t e Accessories business units. Global Services focuses on three key service offerings: repair and strengthening for structures, robotic inspections, and infrastructure health monitoring, which includes cloud-based data acquisition for structural predictive analysis, among other services. "Clients don't see a difference in the way they interact with us," Caravello notes of the reorganization. "But it gives us new efficiencies and initiatives for expansion." Those efforts are being aided by recent domestic and international acquisitions: • In October 2017, DSI Construction announced a strategic partnership i n t h e U n i t e d S t a t e s w i t h Infrastructure Preservation Corp., a robotic engineering firm, to develop technology to aid in the nondestructive inspection of bridges. • In March 2018, the parent company a c q u i r e d A l p i n Te c h n i k u n d Ingenieurservice, which provides robotic inspection and maintenance of infrastructure. Services include c o r r o s i o n p r o t e c t i o n , s p e c i a l assemblies, and repairs. • I n O c t o b e r 2 0 1 8 , t h e p a r e n t company acquired Datum Group, a g l o b a l m o n i t o r i n g c o m p a n y that performs structural health– monitoring services to enhance s a f e t y, s u s t a i n a b i l i t y, a n d c o s t savings. Changing Perceptions DYWIDAG-Systems International's new high-tech inspection and monitoring tools add to its selection of post-tensioning products and services, enhancing its role as a specialty contractor. by Craig A.
