Technology, Certifications & Building Confidence
How Coastal Monolithic's 3D printed concrete wall system aligns with building codes, third-party standards, and engineering requirements in Florida.
How the wall system works
The Coastal Monolithic wall system is a large-scale additive concrete construction method. A gantry-mounted robotic system deposits high-strength concrete in layers according to a digital model, producing a monolithic structural wall with integrated insulation. The result is a continuous concrete structure with no joints, no seams, and no weak points.
Robotic deposition
A gantry-mounted system deposits 7,000+ PSI concrete in precise layers according to a digital model. The print path is programmed before mobilization.
Monolithic construction
One continuous concrete structure from foundation connection to roof bearing point. No mortar joints, no seams, no connection points that can fail under load.
Integrated insulation
Insulation is integrated into the concrete matrix during printing. The PHIUS-certified envelope delivers 60–80% lower heating and cooling energy vs. code minimum.
Certified platform
The wall system carries PHIUS Certification, FEMA Storm Shelter Rating, and ICC-ES evaluation. Documentation is available for qualified review.
Technology platform disclosure
The wall system technology is developed and certified by a third-party additive construction platform partner. Coastal Monolithic is an operator and licensee of this platform, not the developer of the underlying technology. Project-specific results depend on design, engineering, jurisdiction, site conditions, and complete assembly design.
Third-party credentials that matter
The wall system carries certifications from independent organizations. These are not marketing claims. They are documented, tested credentials that provide a basis for engineering review and permitting.
Passive House Institute US
PHIUS+ 2021 Source Zero Certification. The wall system is engineered to reduce heating and cooling energy by 60–80% vs. code minimum. Covers airtightness, thermal bridging, and insulation continuity. Certification earned by the technology platform partner.
Federal Emergency Management Agency
FEMA P-361: Safe Rooms for Tornadoes and Hurricanes. The wall system meets federal criteria for occupant protection during extreme wind events, including wind-borne debris impact resistance. A federal performance designation, not a marketing claim.
International Code Council Evaluation Service
Independent evaluation against the International Building Code (IBC) and International Residential Code (IRC). The evaluation report is the document building departments use to review non-conventional construction methods. Prior permitted projects in Texas, California, and other states.
Florida Building Code
Documentation designed to align with Florida Building Code requirements, including High-Velocity Hurricane Zone (HVHZ) provisions. The 2-hour fire resistance rating exceeds standard residential requirements. Project-specific compliance requires engineering review.
How 3DCP aligns with Florida building codes
The Florida Building Code does not prohibit concrete additive construction. The ICC-ES evaluation provides an established technical basis for permitting review. However, every project is reviewed by the local building department on its own merits. There is no universal approval, only a documented pathway.
ICC-ES Evaluation
The wall system has been independently evaluated against the IBC and IRC. This evaluation report is the primary document building departments use to review non-conventional methods.
Project-Specific Engineering
A licensed Florida engineer prepares structural drawings and calculations for the specific project, site, and jurisdiction. The ICC-ES report is one input; the engineer integrates it into the complete design.
Local Building Department Review
The builder or GC submits the permit application. The building department reviews the project-specific engineering and the ICC-ES documentation. We coordinate with the department to answer technical questions.
Important: certifications and approvals vary by jurisdiction
The ICC-ES evaluation is recognized in many US jurisdictions, but each building department reviews projects independently. Some jurisdictions may require supplemental documentation, additional testing, or specific local amendments. Prior permitted projects in Texas, California, and other states provide precedent, but they do not guarantee approval in a new jurisdiction. We work with local professionals to navigate these requirements on a project-by-project basis. Coastal Monolithic helps coordinate a compliant path with qualified professionals, but we do not guarantee permitting outcomes.
Project-specific engineering is always required
The wall system provides a certified, tested platform. But the specific application (foundation, roof, openings, connections) must be engineered for each individual project. There are no exceptions.
What we provide
ICC-ES evaluation report, PHIUS certification files, FEMA rating documentation, FBC compliance documentation, technical specifications, digital print model, and coordination support during plan review. We answer technical questions from your engineer and building department.
What your team must provide
A Florida-licensed structural engineer who prepares project-specific drawings and calculations. Architectural drawings. Foundation design. MEP plans. Building permit application. Wind mitigation inspection. We do not perform engineering or pull permits.
We do not mobilize for projects that lack a licensed structural engineer or an approved building permit. The ICC-ES evaluation provides an established permitting pathway, but it does not replace project-specific engineering or local building department approval. If you do not have an engineer, we can recommend qualified professionals in your area.
How we talk about credentials
We use careful language about certifications, compliance, and performance because no building system is universally approved, and no credential guarantees project-specific outcomes. The following principles guide how we communicate about the wall system.
Designed to align with applicable requirements
We say the wall system is "designed to align with" code requirements, not "approved under" or "exempt from." Alignment means the system documentation supports compliance, but the building department makes the final determination for each project.
Project-specific engineering required
We state this explicitly and repeatedly. The wall system is a platform, not a turnkey solution. Every project needs its own engineer, its own drawings, and its own permit. We do not perform engineering or guarantee permitting outcomes.
Certifications vary by system, material, design, and jurisdiction
We acknowledge that credentials apply to the wall system as designed by the technology platform partner. Project-specific verification depends on the complete building assembly, local jurisdiction, and licensed engineering review.
We coordinate with qualified professionals
We do not replace engineers, building departments, or inspectors. We support them with documentation and technical expertise. Our role is to make the compliance path as straightforward as possible, not to bypass it.
Common questions about credentials and compliance
The wall system technology deployed by Coastal Monolithic carries several third-party credentials: PHIUS+ 2021 Source Zero Certification from the Passive House Institute US, a FEMA Storm Shelter Rating under FEMA P-361, an ICC-ES evaluation report against the IBC and IRC, and documentation designed to align with Florida Building Code requirements including High-Velocity Hurricane Zone provisions. These certifications were earned by the technology platform partner. Project-specific verification depends on the complete building assembly, local jurisdiction, and licensed engineering review.
The certifications apply to the wall system design as deployed by the technology platform partner that Coastal Monolithic has engaged. Coastal Monolithic is an operator and licensee of this platform, not the developer of the underlying technology. Project-specific results, approvals, and certification verification will depend on design, engineering, jurisdiction, site conditions, and complete assembly design. Full documentation is available upon request for qualified due diligence review.
The International Code Council Evaluation Service (ICC-ES) is the standard body for building product code compliance in the United States. An ICC-ES evaluation report means independent engineers have reviewed the wall system against the International Building Code (IBC) and International Residential Code (IRC). For 3D printed concrete construction, this report is the primary document building departments use to evaluate non-conventional methods. It does not guarantee approval in every jurisdiction, but it provides an established technical basis for permitting review. Coastal Monolithic helps coordinate a compliant path with qualified professionals for each project.
The Florida Building Code (FBC) does not prohibit concrete additive construction. The wall system documentation is designed to align with applicable FBC requirements, including High-Velocity Hurricane Zone (HVHZ) provisions where required. However, every project must be reviewed by the local building department on its own merits. Project-specific engineering is required to ensure the complete structure (including foundation, roof, openings, and connections) meets the wind load and structural requirements for the specific site and jurisdiction. Coastal Monolithic provides technical documentation and coordination support, but does not perform engineering or guarantee permitting outcomes.
Project-specific engineering means a licensed structural engineer prepares drawings and calculations for the specific building, site, and jurisdiction. No two projects are identical. Soil conditions, wind exposure, flood zones, roof design, and local amendments all affect structural requirements. The Coastal Monolithic wall system provides a certified, tested platform, but the specific application (foundation design, roof connection, wind load calculations, and local code requirements) must be engineered for each individual project. We work with licensed engineers and local building departments, but we do not perform engineering ourselves.
The wall system carries certifications for its design and performance as a structural component. A certified building requires that the wall system be properly integrated into a complete structural design that includes foundation, roof, openings, and connections, all engineered for the specific project and approved by the local building department. The wall system certification is one component of a compliant building. It does not, by itself, constitute a certified building. Project-specific engineering and permitting are always required.
We provide the full technical documentation package (ICC-ES evaluation, PHIUS certification files, FEMA rating documentation, and FBC compliance documentation) to your licensed engineer and building department. We are available to answer technical questions during plan review and to coordinate on interface details such as foundation connections, roof bearing points, and MEP penetrations. We do not replace your engineer or building department. We support them with the documentation and technical expertise they need to evaluate the wall system for your specific project.
No. Certifications and approvals vary by system, material, design, and jurisdiction. The ICC-ES evaluation provides a recognized technical basis that is accepted in many US jurisdictions, including Florida. However, each building department reviews projects independently. Some jurisdictions may require supplemental documentation, additional testing, or specific local amendments. Prior permitted projects in Texas, California, and other states provide precedent, but they do not guarantee approval in a new jurisdiction. We work with local professionals to navigate these requirements on a project-by-project basis.
