Overview
Construction of residential buildings in coastal zones presents challenges to the builder not usually found in more inland locations. For all coastal residential buildings, these challenges may include the following:
- Various connection details require additional inspections
- Careful surveying is required to place the building within property line setbacks and above the Design Flood Elevation (DFE)
- Special care which is required to ensure that all elements of the building will withstand the large forces associated with high wind speeds and coastal flooding
- Difficulty of providing durable exterior construction in a moist, sometimes salt-laden, environment
- The requirement to protect and, usually, place utilities above the DFE
In constructing coastal residential buildings on elevated pile foundations, builders face additional challenges:
- Difficulty of constructing a driven pile foundation to accepted construction plan tolerances
- Difficulty of building on an elevated post-and-beam foundation, compared to building on continuous wall foundations
- The additional care that must be taken in constructing a building envelope that will withstand the intrusion of air and moisture under the effects of high wind speeds
This course discusses the construction aspects of the above challenges, as well as basic aspects of the coastal construction process and is divided into the following sections
- Foundation Construction
- Structural Framing
- Building Envelope
- Appurtenant Structures
- Utility/Mechanical Equipment
Fact: The National Flood Insurance Program (NFIP) regulations state that for buildings in V zones, “a registered professional engineer or architect shall develop or review the structural design, specifications and plans for the construction, and shall certify that the design and methods of construction to be used are in accordance with accepted standards of practice” for meeting the provisions of the NFIP regulations regarding buildings in V zones.
The student must take a multiple-choice quiz consisting of twenty-five (25) questions at the end of this course to earn PDH credits.
