Industry standards, engineering software, and professional resources we use and recommend.
V-Zone and Coastal A Zone foundation rules, freeboard, Base Flood Elevation, and what they require on a Rhode Island coastal lot.
How envelope, mechanical, solar, storage, and a 30-year proforma combine into one integrated all-electric design.
ASCE 7-16 Exposure B, C, D explained — the 5,000-foot fetch test and 600-foot inland extension that pick the category at your site.
How we engineer Net Zero homes — full-chain integrated modeling that ties envelope, mechanical, solar PV, battery storage, EV charging, and a 30-year financial proforma into a single design. The cascade of cause and effect, the optimization point, the three principles that govern every analysis, and how the finished home is verified to perform.
Engineering ReferenceA homeowner-facing guide to FEMA flood-zone designations as they apply to coastal Rhode Island — V-Zone open-foundation requirements, A-Zone elevated lowest floors, the Coastal A Zone (LiMWA) condition, ASCE 24, Base Flood Elevation and Rhode Island freeboard, the Elevation Certificate, and how CRMC layers on top.
Engineering ReferenceA plain-English guide to ASCE 7-16 Exposure Categories B, C, and D as applied across Rhode Island — distance thresholds, the 5,000-foot fetch test, the 600-foot inland extension, and how each category appears across the state's coastal and inland towns.
South County Design Group Inc. is a separate and independent Rhode Island corporation that maintains its own professional engineering license and insurance. SCDG is retained as the engineering firm for the companies listed below — each a separately insured and licensed Rhode Island entity operating independently in its own field of business. SCDG's role in each engagement is limited to engineering and Net Zero design services.
NJ&J Builders' custom coastal residential projects span south-county Rhode Island, including Narragansett, South Kingstown, Westerly, Charlestown, and Newport, with structural engineering by SCDG.
