John Dewine looks out his window on the ninth floor of the Standard Building in downtown Cleveland at the construction project he has been leading — The Global Center for Health Innovation (GCHI) and Cleveland Convention Center (CCC). Dewine, a Turner Construction Co. vice president and construction project executive, is no stranger to construction as a 37-year Turner veteran, and no stranger to Cleveland either, as he worked on both the Key Tower and Quicken Loans Arena projects.
Turner Construction, a design/build contractor, brought Dewine to Cleveland to head the project, which the firm completed three months ahead of schedule and on budget in June this year with the help of URS and LMN Architects.
“We got hired in early May 2010,” Dewine says. “From May through the end of 2010 we worked with the designers, engineers, Merchandise Mart Properties Inc. (MMPI) and the county to conduct a series of budgetary estimates and checks to make sure that the project design was staying on budget, providing the programming needs and scope that the county wanted.”
The GCHI (formerly known as the medical mart) and CCC are a $465 million Cuyahoga County project being developed, managed and marketed by MMPI. GCHI brings buyers and sellers together at the world’s first market facility designed specifically for the health care industry.
The state-of-the-art facility integrates permanent showrooms with convention and conference facilities to uniquely meet the innovation, education and commerce needs of the medical marketplace. GCHI showrooms will feature the latest technology from the world’s premier health care and medical manufacturers while the convention center is designed to host health care industry trade shows and conventions.
“The GCHI will be occupied by companies such as GE Healthcare, Cleveland Clinic and Invacare,” Dewine says. “There will be areas for collaboration, which Cleveland Clinic CEO Delos ‘Toby’ Cosgrove hopes will help yield next generation innovations for the medical field.”
The GCHI and CCC project had numerous engineering feats and challenges that Dewine and his team, along with the help of 168 small business enterprise contractors had to overcome.
“On Jan. 3, 2011, at midnight, Armageddon took downtown Cleveland when we started to put in barriers and fencing to corner off three city blocks,” Dewine says.
The GCHI and CCC is located at the corner of St. Clair Avenue and Ontario Street. Before any structure was put in place, a lot of prep work was done to prepare the area for the new buildings.
“In downtown Cleveland the geology is such that the bedrock is almost 200 feet down,” he says. “For heavily loaded buildings, caissons or drilled shafts are imbedded into the rock, and it’s a very unknown-type process. We have an idea of what we’re going to encounter, but you don’t know until you’re drilling the hole.”
Dewine and his team encountered a lot of methane gas, so much that they installed a permanent methane venting system in the facility. But that wasn’t the only issue the Earth’s crust offered.
“The structure and strength of the clays that you drill through are such that if you drilled a hole and left it overnight it would squeeze shut,” he says. “That’s not a good thing, because if it squeezes shut it creates a void somewhere else, maybe under another building. So we had to put steel casings down as we went to prevent the walls from caving in. Getting through that caisson process was huge.”
Besides the groundwork, Public Auditorium and the old convention center provided several challenges for Dewine and his team.
“In the 1960s when they built the old convention center, they successfully incorporated a lot of mechanical and electrical equipment from the convention center to help service and feed Public Auditorium,” Dewine says. “We had to unhook and separate Public Auditorium from the convention center so we could tear the convention center down. Public Auditorium stayed in service, so it was very specific as to what we could and couldn’t do until we had enough of it isolated.”
The other thing that was a real challenge during the build was that the old convention center’s loading dock was at the same elevation as the floor. To create a true loading dock where the trucks are lower for ease of loading in and loading out, Turner had to lower the existing floor by 8 feet.
“As the loading dock goes underneath Lakeside Avenue, we had to lower the subgrade within 2 feet of a 99-inch brick sewer that was installed in the 1880s,” he says. “That took some extra precautions and measures to ensure something catastrophic didn’t happen.
“We had to make sure we didn’t collapse Lakeside Avenue in the process. We had to shore up Lakeside Avenue, remove the columns that supported it with temporary means, dig it out and lower it, put new foundations in and new columns back in, and then release the loads.”
Dewine says the real success of the project and the reason it was completed ahead of schedule was due to a very positive preconstruction period. Turner and its partners were able to sequence the 17-acre site and attack it from a number of locations at the same time.
“I believe the project got completed early because of how successful we were in sequencing the work,” he says. “When we put our guaranteed maximum price schedule together we had about 350 items in the schedule. At the end, we we’re well over 4,000.
“As items became identified and determined in the schedule, we could micromanage it so that you measure and know what you have to accomplish each week. What you don’t accomplish you have to have a recovery plan for how you get it done the next week. It takes a tremendous amount of communication.”
Turner had a general project manager/superintendent meeting every Thursday morning. In addition, the different areas — north of Lakeside Avenue, south of Lakeside Avenue, the GCHI and Public Auditorium — each had their own separate meetings as well.
The result of all those meetings and the hard work done by thousands of people is a finished project ahead of schedule, on budget and without any major accidents. Dewine is happy to now look out his window across the street at a completed GCHI and CCC.
“It’s a real good feeling,” he says. “It’s the successful result of a lot of efforts from a lot of good people. We were blessed with the contractors that ended up being successful in bidding and being awarded the project. We’ve had well over 6,000 employees take home paychecks as a part of this project. The level of cooperation has been unsurpassed.”
By the numbers
The GCHI and CCC is located in the nation’s medical capital, home to the largest concentration of medical leadership in the U.S. More than 230,000 health care professionals, including 43,000 at Cleveland Clinic and 25,000 at University Hospitals, along with more than 600 biomedical companies are located within the region.
