Their choice of SlenderWall® from Smith-Midland Precast plays an important role in the successful reconstruction of a critical 1970’s medical facility. Announced on April 16th, 2015, The Nelson/Harvey Building has been recognized as an ACI Excellence award winner.
SlenderWall architectural precast concrete panel system has been chosen as the exterior cladding for the renovation of the 9-story Nelson/Harvey inpatient facility on the Johns Hopkins Medicine Baltimore Campus.
After decades of wear the hand-laid brick envelope of the facility began failing. The architectural firms Wilmot Sanz and Ayers Saint Gross needed a solution that met two criteria: one, that is was lightweight enough to prevent any need for additional superstructure or foundation costs; and two, that the facility would be able to stay operational during the exterior renovation. SLENDERWALL met both requirements. Its 28 lbs. per square foot specification and unique composite construction will allow for the re-cladding to take place without the removal of the old fascia. The 158 SLENDERWALL panels (27,164 sq. ft.) are designed with a factory-applied Endicott brick facing, keeping in continuity with the campus and the original 1970’s exterior. Johns Hopkins also chose to include factory-applied closed-cell foam insulation and the proprietary H2Out advanced sealant system with leak detection. The addition of these options will provide not only savings in time and onsite trades, but insurance against future air and water infiltrations, as well as continuous insulation adding significantly to the enclosure’s thermal performance.
The project will be certified under Baltimore City’s Green Stars program, at the level equivalent to LEED Silver. This is the first healthcare project to seek certification under this program.
In March 2013, SMC began delivery to the contractor, Whiting-Turner. Completion of the cladding portion of the project concluded in June. The short schedule showcased the benefits of SLENDERWALL in reduced times and costs for production, shipping and installation, as well as decreasing the need for some onsite trades.
