What We Offer
Why You Need a BDA Site Survey Before Installation
Site Survey
A professional site survey is the critical first step in any ERCES or BDA project. Without it, you risk overbuilding, failing inspection, or under-covering your facility’s critical zones.
📊 What Our Survey Provides:
Coverage Mapping – Identify signal gaps and determine exact RF strength
Targeted Design – Eliminate unnecessary equipment and labor
Code Compliance Assurance – Align with national and local AHJ requirements
Cost Savings – Avoid delays, rework, and penalties
🎯 Typical Savings: 15%–40%
💰 Example: A 200,000 sq. ft. building saved $35,000 by only covering necessary areas.
