摘要

Market-rate hosing is driven by costs. Because of the income constraints inherent in renting apartments at market rates, construction costs must be kept within acceptable limits for the project to be viable. In cities such as Manhattan where high-end residential construction is the norm, many developers are not familiar with the variable-cost benefits available from using structural steel to construct residential buildings. A Manhattan apartment building located at 215 E. 23rd Street, scheduled for occupancy this autumn, is testimony to the cost benefits of structural steel, as well as its potential for creative adaptation to meet the special needs of residential construction. The 22-strory building contains 74 apartments targeted to market-rate rental or slightly better. The site it occupies is 48' wide with six-story buildings on each side. The ground floor provides commercial space, and the basement houses mechanical rooms, storage and other building services. The fa?ade is recessed at the seventeenth floor to comply with zoning setback requirements.When owner/contractor Levine Builders, Inc. of Queens, NY, made the initial decision to use steel framing for the project, the first objective for the consulting structural engineer was to maximize the available variable-cost benefits. To make the project work, the challenge facing the designers collectively was to squeeze an extra floor into a vertical site plan constrained by the New York City building code. That meant achieving a 9'-2~(5/8) floor-to-floor finished height for a total of 22 residential floors, an especially ambitious undertaking for steel framing, which is commonly perceived to require 12' from floor to floor.
