Mission-Critical Infrastructure Designed to Unified Facilities Criteria (UFC)
Defense projects answer to a distinct body of criteria: the Unified Facilities Criteria (UFC), Unified Facilities Guide Specifications (UFGS), and service-specific requirements that supersede commercial code where they conflict. Anti-terrorism/force-protection standoff and progressive-collapse provisions shape the structure, secure-facility requirements shape the mechanical and electrical systems, and DoD energy and resilience mandates shape everything. Meeting these standards under the contracting authority's design-quality expectations requires engineers fluent in both the criteria and the review process.
Apex Grid is a veteran-owned firm delivering integrated structural, MEP, civil, and geotechnical engineering for military and defense clients. We design to the governing UFC and UFGS, coordinate ATFP standoff and hardening with the site and structural systems, and produce sealed, DrChecks-ready documents. multi-state team; project availability and stamping are confirmed per project after individual license, firm authorization, discipline, and AHJ requirements are verified, we support installations, contractors, and mission partners on new construction, MILCON, and SRM work.

What information helps define a Military & Defense engineering scope?
Which codes and standards may apply to Military & Defense projects?
ATFP Standoff and Structural Hardening
Anti-terrorism/force-protection design begins with UFC 4-010-01 minimum standoff distances and progresses to structural hardening where standoff cannot be achieved. We apply the DoD minimum standards for buildings — laminated glazing with capture-resistant frames, superstructure detailing to resist progressive collapse per UFC 4-023-03, and component design for blast loads where required. Framing is developed to redistribute loads after loss of a primary member, using tie-force or alternate-path methods appropriate to the level of protection. Site civil design coordinates controlled perimeters, vehicle barriers, and setbacks to achieve required standoff, and connection detailing is documented so hardened performance is buildable and verifiable.
Secure Facilities (SCIF) & Special Access Program (SAP) Infrastructure
Sensitive Compartmented Information Facilities and SAP spaces are engineered to ICD 705 technical specifications alongside the base building code. We coordinate acoustic isolation to the required STC ratings, RF shielding and TEMPEST provisions where specified, and the penetration control that keeps the secure perimeter intact — sealing every duct, pipe, conduit, and structural interface. Mechanical systems are designed for sound attenuation and independent zoning; electrical and low-voltage pathways are separated and protected; and intrusion-detection and access-control infrastructure is accommodated. Our documents define the construction-security requirements and coordination with the accrediting official so the facility is accredited without redesign.
DoD Energy Mandates & Net-Zero Installation Engineering
Federal and DoD energy policy drives aggressive efficiency and resilience targets, and we engineer to UFC 1-200-02 High Performance and Sustainable Building Requirements along with applicable executive-order goals. Designs reduce energy-use intensity through high-performance envelopes, efficient HVAC, and controls, and incorporate on-site generation, battery storage, and microgrid-ready distribution where resilience is required. We perform energy modeling to verify targets, size standby and prime power for mission continuity, and coordinate metering. Rooftop or ground-mount PV is developed to interconnect safely with installation distribution, supporting net-zero and energy-security objectives without compromising mission loads.
Integrated Discipline Scope for Military & Defense Projects
One coordinated engineering team across structural, MEP, civil, and geotechnical — one point of accountability from concept through permit.
Structural Engineering
Military structural engineering integrates conventional loading with force-protection demands. We design to the applicable UFC structural criteria and IBC/ASCE 7, then layer in progressive-collapse resistance and blast component design per the required level of protection. Framing, connections, and foundations are detailed so hardened performance is achievable with standard construction methods.
We also design for heavy equipment, aircraft, and vehicle loads common to defense facilities, coordinating seismic and wind demands for the location.
- Progressive-collapse design per UFC 4-023-03 (tie-force/alternate-path)
- Blast component and connection detailing for required protection levels
- Heavy vehicle, aircraft, and equipment load design
- Foundations coordinated with hardening and standoff requirements
- Seismic and wind design to UFC and ASCE 7
MEP Engineering
Defense MEP balances efficiency mandates with mission resilience. We design HVAC, power, and plumbing to the governing UFC and UFGS, providing standby and, where required, redundant power for mission-critical loads, and sound-attenuated, isolated systems for secure spaces. Electrical distribution is coordinated with generators, ATS schemes, and microgrid-ready architecture.
Mechanical designs meet high-performance-building energy targets while maintaining the pressurization and separation that secure and specialized facilities require.
- UFC/UFGS-compliant HVAC, electrical, and plumbing design
- Standby/redundant power and paralleled generator schemes
- High-performance building energy modeling and controls
- Acoustically isolated, independently zoned systems for secure spaces
- Microgrid-ready distribution and on-site generation integration
Civil Engineering
Site civil work is central to force protection: we lay out controlled perimeters, vehicle standoff, barriers, and access-control points to achieve UFC 4-010-01 setbacks. Heavy-duty pavements are designed for military vehicle and aircraft traffic, with stormwater management meeting federal and installation standards.
Utility corridors, fire access, and site security features are coordinated with the installation's master plan and the building disciplines.
- ATFP standoff, perimeter, and vehicle-barrier site layout
- Heavy-duty pavement design for military vehicles and aircraft
- Stormwater management to federal and installation standards
- Utility corridor and fire-access coordination
- Site design aligned with the installation master plan
Geotechnical Engineering
Subsurface investigation supports the demanding foundations these facilities require, characterizing bearing capacity, settlement, and seismic site class. We provide foundation recommendations for hardened structures, heavy equipment pads, and airfield or pavement subgrades.
Where blast or dynamic loads apply, soil-structure interaction and dynamic response are considered so foundation performance matches the protection objective.
- Subsurface investigation and seismic site classification
- Foundation recommendations for hardened and heavy-load structures
- Pavement subgrade and CBR evaluation for airfields/roads
- Settlement and bearing analysis for mission facilities
- Soil parameters for dynamic and blast-load considerations

Codes & Standards We Design To
Military & Defense projects live and die by code compliance. These are the standards our drawings and calculations are built around.
The DoD Minimum Antiterrorism Standards for Buildings define standoff distances and protective measures that we implement in structural and site design.
This criterion governs design to resist progressive collapse, applied through tie-force or alternate-path structural methods.
The Intelligence Community Directive sets physical and technical security standards for SCIFs our acoustic, shielding, and penetration-control design satisfies.
High Performance and Sustainable Building Requirements drive the energy, water, and resilience targets we verify through modeling and system design.
Unified Facilities Guide Specifications provide the DoD specification format and content we adapt for each project's materials and systems.
The building code and ASCE 7 establish the baseline structural, seismic, and wind loading criteria that UFC provisions build upon.
