Project Details:
The State House is a magnificent piece of architecture and has played a crucial role in the history of both the State of Maryland and the USA. Designed in the mid 18th century, the State House carries the distinction of being the oldest state capitol still in continuous legislative use. Coakley & Williams Construction was selected for the renovation of this historic facility. The
project included a complete replacement of the existing mechanical system, new plumbing systems, and reconstruction of architectural elements to accommodate these changes. The project schedule was of paramount importance. The State House was required to be completely operational during the legislative season which runs from January through April. Accordingly, the renovation had to be completed in an abbreviated 8 month period. That alone was a difficult task – but then the State added more than $3.5 million in work to the contract by change order without adjusting the completion date. The additional work included renovations to the Governors suite which were performed on a design-build basis with architect partner, Urie-Bates. We also replaced the emergency generator, replaced the primary transformer and upgraded power distribution systems, and performed extensive replacement of existing deficient wiring systems. The original electrical system used “rag wire” – wiring covered with cloth insulation. Once this potential fire hazard was discovered, it was imperative that it be rectified. Coakley & Williams took maximum advantage of the time between contract award in December and full mobilization at the beginning of May by making subcontract awards, processing submittals and performing existing condition surveys. Coakley & Williams also secured permission to commence with some of the non-intrusive demolition with the intention of not only getting a head start but also to expose as many concealed conditions as possible so that adjustments could be made to the work plan to minimize delays. Another challenge was the protection of the historic building. The wood structure in the dome is over 200 years old and posed an extreme fire risk. An intensive fire prevention plan was developed and executed. Similarly, a detailed action plan was developed to protect the building’s rich finishes and ornamentation from damage. Existing walls and floors were covered with masonite. A historical preservationist was on retainer to approve removal and replacement techniques of any of the historical plaster, millwork or hardware. Work areas were limited to ensure that adequate supervision could be maintained at all times. Of particular concern was the protection of the majestic Tiffany skylights which overlook the monumental spaces. Site logistics also presented a problem. The site is located in downtown Annapolis and the available laydown area at the building perimeter was severely limited. The only access point to remove demolition debris and bring in new equipment was at the attic through a small skylight. The State recognized that these challenges were inherent in the project when it advertised for bid. Accordingly, it decided to select its contractor on the basis of a “best-value” procurement rather than a low bid approach. In addition to a price proposal, the State required potential contractors to submit relevant project experience, the proposed project team, a detailed CPM schedule, a work plan and references. Despite the additional challenges introduced to the project during construction, the project team prevailed and managed to accomplish the original goal – on time completion, actually reaching substantial completion three weeks early.
