Breathing Life Back Into Your Historic Building Envelope
New York City's Facade Inspection Safety Program (FISP), formally known as Local Law 11, requires the facades of buildings of six or more stories to be inspected for safety every five years. This measure was a replacement for Local Law 10, originally enacted in the late 1990’s, which required inspections of only the front side of buildings. The latest inspection period, Cycle 8, started in February 2015 and ends in February 2020.
When restoring a building, one of the first steps is giving the building an assessment of its current condition. The structure should be examined, which includes the roof, foundation, walls, gutters, windows and interior leaks.
Buildings in New York City typically have membrane roofing made of synthetic rubber, modified bitumen or thermoplastic. With flat roofs, it’s important to note any ponding water and other signs of damage. If the roof is slate, it’s important to look for damaged and missing material.
As for the exterior walls, unsafe conditions include items such as loose or cracked bricks, cracked windows, missing mortar, improperly secured air conditioners, and any other conditions which may be dangerous to pedestrians below. Unsafe conditions must be dealt with immediately which involves installing a sidewalk shed within a 30-day period. Then an amended report must be filed confirming the repairs required. Extensions of up to 90 days may be granted if necessary.
The SHA team is a full-service architectural firm. Our goal is to ensure that your building is both functional and beautiful, and we pay special attention to the historic details of the building exterior. In order to complete accurate repairs, we utilize the original materials or replicate them to achieve the appearance of the original design.
Another option for exterior building restoration is adaptive reuse. Adaptive reuse projects maintain the historic envelope while updating the interior. Updating the existing interior rather than the construction of a new structure saves money and time. This option is also a means of preserving the history, identity and charm of a city. Adaptive reuse of buildings is also eco-friendly, as fewer building materials are being utilized.
If you find yourself in need of exterior building restoration or adaptive reuse design projects, contact Scott Henson Architect, located in New York City. Our approach is innovative, sustainable and respectful in order to preserve the integrity of historic structures.Read more...
Interior Architecture for Historic New York City Buildings
Preservation and renovation of interior spaces in historic buildings involves a careful and detailed structural assessment of the materials, environment, and applied stresses to ensure that the existing walls, floors, and other load bearing structures are structurally safe. This structural assessment can involve a visual inspection to assess the structural integrity of load bearing walls and joints. Structure can also be analyzed in greater detail through impact-echo vibration testing, which creates a computer-generated model of material strength.
Some damage to an interior is visible, such as water damage, cracked bricks, and missing mortar. However, some interior elements, such as columns, concrete flooring and welded steel structural elements, may need testing to ensure that the structure of the material is holding up, without fractures or other signs of impending failure.
With historic buildings, patching or attempting to strengthen a failing structural area can accelerate damage or failure. Detailed and complete structural assessments are a first step, with priorities for repair and renovation detailed.
When bringing a historic building into modern use, safety and access issues are as important as maintaining historic integrity in materials and use. Fire safety and access for those with mobility challenges are mandated in any public use building and may require changes to the interior space utilization.
In addition, a change in the planned use of the building requires assessments of how people will navigate the building. Emergency egress and bathrooms, for instance, are built based on the expected number of people using the building. Areas of potential bottle-neck during an emergency evacuation can be modeled by computer programs or viewed with a visual inspection. Modern systems, such as HVAC and plumbing, might also require changes in the interior structural elements, as these systems will need to be accessed for maintenance and repair.
The structural assessment will include areas such as materials safety, structural integrity, and immediate safety issues. A planned renovation will detail the necessary adaptive changes to an interior, specifically safety, access, and the buildings mechanical system. After these critical points are evaluated and planned for, elements of the interior renovation will be planned in order to maintain as many historic features as possible.
