Construction sites are buzzing hubs of activity—packed with tools, heavy machinery, and materials that are both valuable and vulnerable. But when the workday ends, these same sites can quickly become targets for theft, trespassing, and vandalism. With millions lost each year in stolen equipment and project delays, construction site security is no longer optional—it’s essential.
At Security Gate & Access, we’ve spent over 40 years helping builders and contractors acrohow-toss Western Washington secure their sites. From permanent systems to portable fencing, from electrified barriers to advanced surveillance and access control, we offer practical, reliable solutions tailored to the real-world challenges of job site security.

Why Construction Sites Are High-Risk Targets
Unfinished structures, open perimeters, limited lighting, and constant equipment deliveries create the perfect storm for criminal opportunity. In fact, if you’ve ever wondered how to prevent construction site theft, it starts with understanding just how vulnerable most job sites are.
Thieves often target:
- Tools and machinery: Easy to lift and sell
- Copper and wiring: High resale value
- Fuel and materials: Frequently left unsecured
- Vehicles and trailers: Often parked in open areas overnight
Beyond the direct cost of stolen items, these incidents lead to insurance claims, project delays, worker downtime, and in some cases, liability issues if someone is injured while trespassing.
The solution? A layered security strategy, led by expert guidance and smart investment in the right systems.
Electric Fencing: A Powerful First Line of Defense
Let’s start with one of the most effective (and underutilized) options: electric fencing.
An electric fence doesn’t just create a physical barrier—it adds a psychological one. When trespassers see an electrified perimeter, they know immediately that the site is being actively secured. And if they decide to test it, the non-lethal but painful shock will quickly change their mind.
For construction managers looking for quick deployment, SGA offers portable security fence solutions that can be installed and energized in a fraction of the time it takes to build permanent infrastructure. These systems are ideal for temporary job sites or projects with changing layouts. Need to expand the fence line next week? No problem—our modular systems adapt as fast as your schedule does.
And because our electric fences can be integrated with alarm systems, cameras, and lighting, they don’t just deter—they detect and respond.
Portable Fencing for Flexible, Real-World Protection
One of the biggest challenges in construction site security is the changing nature of the environment. You’re not securing a fixed building—you’re managing a living, moving project.
That’s why portable fencing is such a valuable asset. At SGA, we provide fencing solutions from Gallagher Security that:
- Are quick to install and remove
- Can be electrified for added deterrence
- Include signage to meet safety regulations
- Can be configured to accommodate changing site boundaries
Whether you’re building a single home or managing a large commercial development, our portable fencing options are engineered for strength, visibility, and adaptability. It’s a cost-effective way to create defined, protected zones even as the footprint of your job site evolves.

Gate Systems and Access Control
A solid fence is just the beginning. If you don’t control who’s coming and going, your perimeter security falls apart fast.
That’s why SGA integrates custom gate systems and access control solutions as part of a comprehensive job site security plan. Whether you need keypad entry, keycards, vehicle tracking, or remote access through mobile devices, we help you monitor and manage every entry point.
And during peak hours—when subcontractors and suppliers are coming and going—you need a system that’s not just secure, but efficient. With our automated gate solutions, you won’t bottleneck productivity just to keep the site safe.
Plus, once the workday ends, access control systems become one of your most valuable tools for overnight security. No more guessing who was on-site last. Our systems keep detailed logs and can even send real-time alerts.
Construction Site Surveillance: Eyes on Every Corner
Fences and gates are essential, but if someone does manage to get past them, you need another layer of protection. That’s where construction site surveillance comes in.
SGA offers security camera systems specifically designed for rugged outdoor use. These aren’t your average home security cameras—these are high-resolution, weather-resistant units equipped with motion detection, night vision, and remote viewing capabilities.
And because no two job sites are the same, we customize every system to ensure optimal placement and performance. Whether you need panoramic coverage, zoom capabilities, or mobile units that move with your project, we make sure every vulnerable angle is protected.
Footage can be stored locally or streamed to a cloud platform, giving site managers and business owners access from anywhere. In the event of a theft or incident, you’ve got clear, time-stamped evidence—often the key to recovering assets and identifying culprits.
Building a Smarter Security Strategy
Effective construction site security isn’t about buying a fence or installing a few cameras—it’s about creating a comprehensive strategy that fits your budget, timeline, and specific vulnerabilities.
At SGA, we help clients build smarter protection plans with a mix of:
- Electric fencing for deterrence
- Portable security fence and barriers for flexible site control
- Gate automation and access control for entry tracking
- Construction site surveillance for full-coverage monitoring
- Maintenance and support to keep systems running smoothly
Because we’ve been doing this for over 40 years, we understand how to protect properties in Western Washington’s unique climate and regulatory environment. We know what works and what doesn’t.

Don’t Wait for a Theft to Take Security Seriously
Far too often, we hear from construction managers after a major incident, once thousands of dollars in tools, copper, or machinery have disappeared. At that point, it’s about recovery, not prevention.
We’re here to help you get ahead of the problem. Whether you’re starting a new project, expanding your current site, or responding to recent threats, now is the time to invest in security systems that work as hard as you do.
Let Security Gate and Access design a solution that meets your needs today—and evolves with your project tomorrow.
