Securing land is the first essential step in building a custom home. Considerations in land choice include surrounding developments, zoning, property dimensions, utilities, roadways, adjacent properties, land views, schooling, property hold time and budgetary guidelines.

Land Preparation

Homeowners on average, spend between $2,500 and $5,200 to clear land and prepare a project site for construction. Land preparation starts with surveying and comparing the land with construction plans to determine the necessary tasks before construction can begin.

Site preparation begins with clearing the land, grading, drainage control, erosion prevention, staking, securing access roads, and utility connecti

Architectual Design

The architectural process can be divided into distinct phases, which may vary in order and definition with each architectural firm.

• Pre-Design
• As-built Measuring
• Schematic Design
• Bidding
• Design Development and Permitting
• Construction Documents
• Construction Administration

The key to ensuring a quality architectural process is the management of clear communication and expectation. American Strong Homes partners with a variety of diverse architectural firms to accommodate any necessary building specifications and design details.

Structural Engineering

Although the structure of a home is first considered by the Architect, ultimately the Structural Engineer considers the supporting framework to ensure it will withstand the stresses and pressures of the environment, the specific requirements of the architecture (clear-span, fenestration, economic considerations, materials, etc.) and remain safe, stable and secure throughout its use. We utilize Spray Rock’s engineering department who specializes in complete steel shell construction to accommodate all types of design and load requirements.

Construction Permitting

Permitting is traditionally handled by the building contractor and serves multiple purposes which include but are not limited to:

• Legality – Avoid Fines
• Structural Safety
• Contractor Honesty
• Building Guidelines
• Code Requirements
• Insurance Benefits
• Real Estate Value

Generally, the permitting process takes between 6 to 8 weeks to finalize with local building and zoning before officially “breaking ground”. Traditional construction methods (block and wood) are postponed until the permitting process is complete. However, Spray Rock not only exceeds current building codes until 2030, but also affords a headstart to begin the fabrication and assembly phase once engineering is approved to expedite production and save build time.

Foundation

The foundation, which is generally a concrete slab, is the underpinnings of the structure. The typical house foundation is a four inch, uniform thickness, concrete pour over a compacted soil surface. It includes a termite barrier covered by heavy-duty polyurethane sheeting and heavy gauge (typically #4 or #5) rebar and wire mesh to allow for concrete expansion due to temperature change. The foundation thickness is determined by structural engineering based on load requirements and can increase up to 8 inches or more.

Scope of Work

Scope of work for home or commercial building installation is performed under Our licensed general contractor. Net Zero Building Systems, Inc. is limited to providing materials, bare bundled or factory assembled steel walls and trusses, foam board cladding and computer aided engineered shop drawings.

All material designs and standards are based on the SPRAY ROCK / NET ZERO STAND-UP WALL SYSTEM in general conformance with the plans and specifications as stated in the architectural plans by the Architect/ Designer of record for the project.

Spray Rock / Net Zero will provide an authorized installer who will work with our general contractor and will be licensed in the state where the project is built who carries workman’s compensation and liability insurances. The authorized general contractor who installs the building will conduct its services under the supervision of the Project Manager / General contractor of record.

Factory Wall Assembly

The Spray Rock building system uses quality American made, 85% recycled, 16-gauge galvanized steel for all exterior walls. The interior walls (also made of galvanized steel) are 18 – 22 gauge, depending on structural requirements, far surpassing interior wall thickness typically found in U.S. building.

The floor trusses (aka floor joists) and roof trusses are made of 18-gauge galvanized American made steel. Galvanization of steel studs and trusses ensures lifetime durability within even the harshest salt & high humidity environments.

All wall and truss assemblies are manufactured in our own factory using computerized steel roll forming machines to exacting engineering specifications. Each panel is stamped with an identification number to indicate its exact location within the building. Both interior and exterior walls are pre-punched for electric and water service holes during fabrication.

Foam board installation

The polystyrene R-12 insulation foam board is cut on CNC machines and pre-installed at the factory on all exterior walls to ensure precise fit prior to shipment to the job site. Each board is also impregnated with Borate salt which prohibits insects from entering through the exterior walls.

Wall and Truss Installation

All exterior and interior wall framing is installed on the job site by experienced installation crews using the factory assembled wall panels. Floor and roof truss installation follows the same process.

Concrete Spray

Just prior to the gunite concrete (same as a swimming pool) spray application galvanized wire mesh and D-Wire are installed on all exterior walls to ensure concrete adhesion to the foam board, structural integrity and eliminate potential cracks in the concrete after it hardens.
