Lynchburg General Hospital

 

The Lynchburg General Hospital expansion project carried out in the state of Virginia resulted in tangible cost as well as substantial time savings through the implementation of innovative process and technology.

Barton Malow company Founded in 1924, Barton Malow has served as a general contractor in the U.S. market for nearly fifty years. Offering both design and construction services, the company is organized by markets, one of them being health care. Barton Malows Preconstruction group supports these markets with a diverse estimating system, in addition to their 25 full-time engineers and architects. Their expertise includes all facets of project planning, value engineering and manpower planning. The corporation employs 1,550 full-time staff and has experience in 37 states and the District of Columbia. Company revenues for the previous five years are in excess of $1 billion annually. Barton Malow is consistently ranked among the top 10 builders in the nation in their niche markets. Headquartered in Southfield, Michigan, the company has regional offices in Maryland, Virginia, Arizona, Ohio, Illinois, Florida and Georgia. Project control centers are established at all major project sites.

Promoting progress with efficient construction
Health facilities projects are a major source of construction in the United States, and Barton Malow has delivered a wide variety of them. To achieve the high-set goals of their clients, Barton Malow provides facilities that support growth, progress and innovation within health care. They do this by offering services that encompass the entire building process, while maintaining their roots in constructing strong, quality buildings. What significantly helps in promoting their clients progress is using software that does the same for construction, such as the Tekla Structures 3D building information modeling (BIM) solution.

As a result of Tekla Structures open platform as well as its unique collaboration possibilities design coordination and communication of all project participants in a shared, real-time 3D environment iit is possible to effectively minimize construction costs, while sufficiently controlling risk. Teklas modeling interface can be used to supplement 3D objects, which are not structural in nature, to better develop 3D design and construction coordination. Teklas solution also enables efficient conflict resolution, which is equally important for the success of a construction project. The ability to both create construction specific model objects, as well as, combine other disciplines 3-dimensional information enables maximum usage of project planning and coordination resources.

Progressive patient care in a tower of brick and glass
The five-story patient care tower at Lynchburg General Hospital was designed to meet the growing demand for services, to be patient and family-oriented, yet still accommodate the advanced equipment and technology needed to care for todays patients.

The 140,000 squarefoot tower of brick and glass includes 108 patient rooms and other facilities, such as treatment units and one floor of shell space for future expansion. The tower rooms will be wired for a future move to a digital, computerized environment, such as electronic patient records, and be designed to include the latest in patient monitoring equipment. The addition is built across the front of the hospitals existing main entrance.

Construction of the state-of- the-art facility is scheduled to be completed in 2007. In addition to the patient care area, the project includes renovation of 65,000 square feet of space at Lynchburg General Hospital, with an emphasis on improved patient care support areas. The cost of the patient care tower is estimated at approximately $64 million. More information at: www.centrahealth.com/about/construction.aspx

Savings through phasing and 3D modeling coordination
Compared to other projects at Barton Malow, the Lynchburg General Hospital expansion is unique due to the phased release of bidding and construction, explains Ronald B. Sinopoli, Project Manager at Barton Malow. As the construction manager, Barton Malow released three project engagement letters (PELs), which subsequently determined the phasing of the project. These included Site Utilities Package, Structural Package, and Architectural/MEP Package, which rolled together set the GMP for the project. Tekla Structures 3D model and coordination was utilized in all of these phases, which significantly facilitated the overall construction management process and resulted in substantial tangible savings.

According to the Barton Malow project team, known savings from MEP contractor not re-detailing the structure in 3D environment amount to $20,000. In addition to the tangible costs savings realized on this project, a wealth of errors and costs were avoided in adopting the collaborative way of working. It is quite difficult to quantify savings from costs and errors that are prevented due to a more effective workflow between the project disciplines. After acquiring Tekla Structures license and maintenance for the company, all of the implementation was done at no added cost to the project. For Barton Malow, it was extremely important that no upfront costs were put in the project to counteract the savings.

Software implementation: It's all in the model
The biggest hurdle was finding a way to make the unique file types used by each contractor interchangeable. Thanks to Tekla Structures superb interoperability, data transfer was possible and benefited project management. The steel detailer provided Tekla Structures (Xsteel) files of the entire structure to import into AutoCad, which were broken up by floor as requested by the mechanical detailer. Once the mechanical detailing was complete, importing the files back into Tekla Structures with the shapes as solids (duct, flex, pipe equipment etc.) was, according to Sinopoli, a huge leap: it allowed for easy viewing and clash checks, which in his opinion was highly beneficial.

An entire floor of mechanical detailing can get extremely busy and wire frames just dont cut
