The project was nearly complete when the general contractor discovered the problem. The access control system, installed by a subcontractor late in the construction phase, couldn't integrate with the building's video surveillance. The result? Three weeks of delays, thousands in additional labor costs, and one frustrated client.
This scenario plays out across construction sites more often than it should. Security systems—including access control and video surveillance—have become essential components of modern commercial buildings. Yet many builders treat these systems as afterthoughts, leading to expensive mistakes that derail timelines and budgets.
After 85-plus years serving the construction industry, we've seen these patterns repeat. Here are five critical errors that cost commercial builders time and money, and how to avoid them.
Treating Security Systems as Last-Minute Add-Ons
Most commercial projects follow a logical sequence: foundation, framing, electrical, finishing. Security integration often gets pushed to the end of this list, treated as a simple plug-and-play addition rather than a critical building system.
This approach creates problems. Access control and video surveillance systems require careful coordination with other trades. Door frames need proper preparation for electronic hardware. Conduit runs must align with architectural plans. Network infrastructure needs adequate capacity for IP-based security devices.
When security planning happens during the design phase, these elements integrate seamlessly. When it happens during punch-list week, contractors face change orders, wall demolitions, and schedule extensions.
Mixing Incompatible Systems and Components
A commercial developer in Salem recently learned this lesson the hard way. To save costs, they sourced access control hardware from multiple vendors. The door frames came from one supplier, electronic locks from another, and the control panel from a third.
The systems didn't communicate. The integration contractor spent days troubleshooting compatibility issues. The project that should have taken two weeks stretched into six.
Security systems function as integrated ecosystems. Commercial doors, architectural hardware, and electronic access control must work together from the start. Mixing incompatible components creates technical debt that compounds throughout installation.
Underestimating Infrastructure Requirements
Modern security systems demand robust infrastructure. IP-based video surveillance cameras require network bandwidth. Access control systems need reliable power and backup systems. Card readers and electronic locks depend on proper conduit pathways.
Many builders underestimate these requirements, discovering too late that the building's network can't handle the camera load or that power drops are insufficient for electronic hardware. Retrofitting infrastructure after walls are closed costs exponentially more than planning it correctly from the beginning.
Skipping Professional Installation for Critical Components
Some construction companies handle door installation and building specialties with in-house crews or low-bid subcontractors lacking security integration experience. This works fine for standard commercial hardware but fails with sophisticated security systems.
Access control installation requires specialized knowledge. Proper door frame preparation, correct hardware mounting, precise alignment of electronic components—these details determine whether systems function reliably or generate service calls for years.
Professional installers who specialize in security integration understand these nuances. They know how architectural hardware interacts with electronic systems. They anticipate problems before they occur. The modest additional cost for experienced installation prevents expensive callbacks and warranty issues.
Failing to Plan for Future Expansion
Commercial buildings evolve. Tenants change. Security requirements grow. Yet many builders install systems with no expansion capacity, forcing complete replacements when needs change.
Smart security planning includes scalable infrastructure. Extra conduit runs cost little during construction but save thousands later. Modular access control systems accommodate additional doors without major overhauls. Network infrastructure with excess capacity supports future camera additions.
Building Security Systems That Work
These mistakes share a common thread: they stem from treating security integration as a commodity purchase rather than a specialized construction discipline. The lowest bid rarely delivers the best value when complex systems are involved.
Successful commercial projects integrate security planning early. They specify compatible components from the start. They allocate proper infrastructure. They use experienced installers who understand both construction and security technology. They plan for future needs.
The construction industry has evolved. Buildings aren't just structures anymore—they're sophisticated systems where doors, frames, hardware, and electronic security work together. Projects that recognize this reality from day one avoid the costly mistakes that plague others.
Trimble Company has served the construction industry since 1936, providing comprehensive solutions for commercial doors, overhead doors, access control, video surveillance, and building specialties. Our experience spans the complete spectrum of CSI Sections 8 and 10, from basic architectural hardware to sophisticated security integration.
