Physical Security Consulting Services for General Contractors
Vendor-neutral support for the security scope on your projects, from product selection and budget through integrator oversight, commissioning, and owner handoff. Access control, intrusion detection, and video surveillance, handled by someone who's built at scale.
Support at Every Phase of the Security Scope
Security is one of the most specialized scopes on a job and one of the easiest to get wrong late. Marlow Aegis steps in wherever you need an experienced, independent security partner: before buyout, during submittals, through installation, or at turnover. Engage for a single phase or the full project.
Services for General Contractors
Security Product Evaluation & Recommendations
Vendor-neutral assessment of access control, intrusion detection, and video surveillance options, scored on fit, total cost of ownership, and whether each choice will survive AHJ review without a scramble.
What you get:
A documented recommendation you can defend to the owner and the inspector
A budget reality check against the actual system requirements
Code and AHJ considerations flagged during selection, not at inspection
Best for: preconstruction, estimating, value engineering, and buyout
Security Design Review & QA/QC
An experienced review of the security drawings and specifications at each phase, catching gaps, overspecs, coordination conflicts, and code risks while they're still inexpensive to fix.
What you get:
Documented review comments at schematic, design development, and construction document phases
Conflicts between security, electrical, low voltage, door hardware, and IT flagged early
Clear questions to send back to the design team
Best for: design-build and design-assist projects, and bid package review
*Review and comment only. Engineered design and stamped documents stay with the licensed engineer of record.
Integrator Submittal Review
A real technical check on integrator submittals against the design intent, the budget, and the owner's standards, so what gets installed is what was actually approved.
What you get:
Product data, shop drawings, and system riser review
Substitutions and deviations identified with a clear recommendation
Fewer surprises between submittal approval and installation
Best for: any project with a security integrator subcontract
Security Project Management & Coordination
Hands-on oversight of the security scope through the build. The integrator is coordinated around your crew and the owner's facilities team, with sequencing, submittals, and progress tracked so the work lands on schedule instead of at closeout.
What you get:
Security scope sequenced into the master schedule
Coordination with electrical, low voltage, doors and hardware, and IT
Budget, code, and schedule conflicts flagged the week they appear
Best for: active construction, fast-track schedules, and complex or phased projects
Commissioning Support & Owner Handoff
The engagement stays active through commissioning, not just to the point of handoff. The owner gets as-builts and operating documentation precise enough to maintain the system years later, plus training their team will actually use.
What you get:
Commissioning and functional testing oversight
As-built and O&M documentation review for completeness
Owner training that reduces post-turnover callbacks
Best for: closeout, turnover, and punch list
Services for Owners, Developers, and Portfolio Teams
Marlow Aegis also works directly with owners and developers who need an independent security voice on their projects or across a portfolio.
Security Owner’s
Representation
An independent advocate for the owner through every phase, keeping the security scope aligned with the owner's standards, budget, and schedule from concept through turnover.
Physical Security Standards Development
Clear, version-controlled security standards that project teams, architects, and integrators can follow consistently on every site. Built on direct experience co-authoring Amazon's first global Logistics Physical Security Design Build Book.
Fractional Security Program Management
Senior security program leadership without adding full-time headcount, keeping the same level of rigor across a growing portfolio of projects.
What Marlow Aegis Does, and Where the Line Is
Marlow Aegis provides vendor-neutral product evaluation, design review, project management oversight, and integration coordination for physical security systems.
Marlow Aegis is not an installing contractor and does not perform engineered system design, layout, or code sign-off. Those stay with your licensed contractor, engineer, or the manufacturer's design team, and every engagement letter says so.
With nothing to install and nothing to sell, every recommendation is only ever about what's right for the project.

Security Consulting FAQs
-
As early as preconstruction. The earlier product, budget, and code issues are identified, the cheaper they are to fix. Submittal review and commissioning support are still valuable at any stage.
-
An integrator sells, installs, and services security equipment. Marlow Aegis is independent and doesn't sell or install anything, which keeps every recommendation focused on what's right for the project.
-
No. Marlow Aegis reviews designs, evaluates products, and oversees the security scope, but engineered design, layout, and code sign-off remain with the licensed engineer or contractor.
-
Access control, intrusion detection, and video surveillance, including how those systems coordinate with electrical, door hardware, and IT on your project.
-
Yes. Engagements can cover a single phase, a full project, or ongoing advisory across multiple projects
-
Every engagement is scoped to the project and the phases involved. Schedule a consultation to talk through your needs.
