Scope
A Condition Assessment Report dated September 4, 2014 and a Rehabilitation Analysis and Recommendations report dated December 8, 2014 were prepared by The Burns Group and Greeley & Hansen. Also DDC issued a Field Inspection Report dated March 3, 2014. All reports should be reviewed and used as a basis to prepare preliminary and final design. The selected consultant shall utilize the structural scheme partially developed in the December 8, 2014 Greeley & Hansen report which is to provide intermediate columns and footings to reduce the span of the existing W36 members currently spanning over 100 feet. The selected consultant will be required to evaluate/analyze structural elements in accordance with the requirements of the latest DNSY Garage Design Standards for the heaviest fully loaded salt spreader trucks. The building is to be rehabilitated including extensive structural work (demolition and replacement of cellar-level slab and entrance ramp slab, demolition, and replacement of first floor slab, adding intermediate columns and footings, etc.). Total replacement of building systems (electrical, fire protection, plumbing, HVAC including building management system) and architectural renovation of the entire building is required. Remedial options /scopes of work and cost estimates shall be submitted to DSNY for review prior to starting design. After first floor slab and ramp demolition, the existing exposed structural steel shall be inspected, evaluated and repaired/reinforced as required.
