CCPCS The MakerSpace Renovation Project The project is located at the 2335 18 th street NE, an approximately 19,207-square foot, two-level, flex industrial property with on-site parking. The proposed renovation will be a level 3 alteration to the existing building per the applicable international existing building code and will require building systems up to the current code as anticipated work area exceeds 50% of the gross building area. The Project included site utility work to suit the new renovated building. The water mains around the site are eight” and twelve” in diameter any new water or fire connection which did not require the replacement of any existing DC water mains. Additional Storm Water Management controls were required as the conceptual renovation costs exceeded the DOEE threshold of 50% of the market value of the structure before the improvement and or land disturbance exceeding 5,000 sq.ft. These requirements were addressed on site with a green roof system. Structurally, in summary, the masonry walls of the second floor had numerous cracks, due to the lack of control joints in the exterior walls that need to be repaired. For the east, west and south exterior second floor walls most of the repairs were standard tuck pointing of the mortar joints and lintel replacement. The wall piers supporting the roof beams were repaired as well. The north exterior walls of the building were in bad bowed condition that we ended replacing in entirely. The entire roof and roof framing were replaced by installing new TPO and Green roof. The building structure is a perimeter of load bearing masonry walls and interior steel column and beam system. The lower level is slab on grade, and first level is bar joist with decking and concrete slab, and roof is a bar joist and mineral decking. Exterior walls are clad in brick masonry except for the south wall with appears to be a single wythe CMU wall. The roof system is a bituminous sheet roofing system. Exterior window units are single panes glazing in non-thermally broken extruded aluminum. Mechanical systems were designed to be appropriate for an educational environment for a maker space facility. Each floor will be fed from a 30-ton roof mounted gas fired roof top units which will serve most of the spaces. Return air will be reduced. Exhaust air will be provided from the restrooms. Consideration of heat recovery at the roof top units will be examined during design. A separate 10-ton gas fired roof top units were provided for the recording studio spaces. The ductwork for this area was ducted supply and return with sound lining. The rooftop unit and penetrations will not be over top of the studio spaces. The building architectural design included a wood shop to transfer air from the education space and was provided with a dedicated exhaust system to the roof. This Project is achieving LEED Gold Certification.
