BIM Designs is responsible for the furnishing of CAD resources to facilitate 3D model population and spatial coordination of mechanical piping, HVAC, and plumbing systems, including hangers, provision of Trimble points and sleeves, shop and construction drawings for fabrication, and equipment layout drawings. It also includes equipment pad drawings, bills of material, sleeves and inserts for decks and sheer walls, and Trimble points for the same.

Spring Street North Block calls for two towers featuring 565 residential units along with 8,400 square feet of retail, office and restaurant space. There will be eight levels of underground parking for 387 vehicles that will be accessible via Hubbell Place. Residents will have two large bike rooms, a package room, gym, fourth floor decks and dog runs, and roof deck amenities.

Spring Street North Block floor plans include studio, open one-bedroom, one-bedroom and two-bedroom units, with some units featuring private decks. There will also be six penthouse units in each tower. In total, the project is about 770,000 square feet.

An alley vacation between Seneca and Spring streets is needed for the proposed landscaped woonerf that splits the block and separates the two towers. In addition to the woonerf, there will be east-west pedestrian mews that connect to the 5,785 square-foot public plaza.

The terrace-designed public plaza will include a water feature and a large open space suitable for musical events, public markets and outdoor movies. The restaurant’s outdoor seating area is designed to face the plaza. A 1,300 square-foot retail bay will face Eighth Avenue and the project’s three residential live/work units will face Spring and street level.
