A vendor neutral building automation contractor services your existing BAS platform without requiring you to replace it or sign a proprietary service contract with the original manufacturer, which is what most Detroit commercial building owners discover they need after their OEM support contract renews at a 40 percent increase. Samco Facilities Maintenance provides vendor neutral BAS and BMS service for Metasys, Niagara, Tridium, and legacy pneumatic systems across Southeast Michigan. Call (734) 838-6300 to schedule a BAS audit or service visit.
Why BAS Vendor Lock In Costs Facility Managers More Than They Realize
Building automation system vendor lock in does not announce itself. It arrives as a renewal quote from the OEM support desk that is 30 to 45 percent higher than last year, followed by a service technician who will only reprogram the system using proprietary software that no other contractor can access. The facility manager is not locked in because the technology requires it. They are locked in because nobody specified open protocol access rights when the system was installed.
A high-rise in Southfield we first assessed in 2021 was paying its original Metasys contractor $84,000 per year for a support contract that covered one annual system review and emergency dispatch at a four-hour response time. The facility manager had assumed for years that Metasys required a Johnson Controls service contract to function. It does not. Metasys runs on BACnet, which is an open protocol. A vendor neutral contractor with BACnet programming competency can service, modify, and program the system without OEM permission. When they switched to a vendor neutral contract, their annual BAS support cost dropped to $38,000 for a broader scope including quarterly reviews, alarm rationalization, and trend log analysis.
The same dynamic plays out with Niagara Framework systems running on Tridium hardware across Detroit office buildings, Troy corporate campuses, and Auburn Hills automotive facilities. Niagara is a licensed platform, but the license does not restrict third-party service. It restricts development of new Niagara applications. Servicing, configuring, and monitoring an existing Niagara installation does not require an OEM service contract.
The Service Scope for a Working BAS
A BAS that was properly installed but never properly serviced is not a working BAS. It is a system that has accumulated deferred alarm rationalization, controller firmware updates that were never applied, and setpoint drift that nobody caught because nobody was reviewing trend logs. The result is a building that runs less efficiently than it should and a facility manager who does not trust the system readings.
A working BAS maintenance program covers the following on a defined schedule. Alarm database review and rationalization, because BAS systems that generate 400 alarms per day train operators to ignore them, and the actual critical alarm gets buried in the noise. Trend log review, to catch setpoint drift, economizer lockout failures, and scheduling errors before they show up in an energy bill. Controller firmware and software updates at the platform-appropriate cadence. Point verification, meaning a field technician confirms that sensor readings match field conditions on a sample basis each year. Occupancy schedule review tied to the building’s current use patterns, since most BAS systems have setbacks that were programmed for the original tenant and never updated.
Here is what we actually see. Eight of ten BAS systems we inspect in Livonia and Detroit have at minimum three occupied setpoint schedules that do not match the current building occupancy. They are heating or cooling unoccupied spaces on the original tenant’s schedule. One of those buildings was conditioning a corner of a Detroit office floor that had been vacant for two years. The BAS did not know, because nobody had updated the schedule, and the facility manager had not thought to ask.
The Michigan Angle: Detroit High Rises and Legacy Pneumatic Controls
Detroit’s commercial building stock includes a significant number of mid-rise and high-rise buildings constructed in the 1960s through the 1990s that still run pneumatic control systems. These buildings were not built with BACnet. They were built with compressed air actuators, pneumatic thermostats, and analog controllers that predate digital automation entirely.
A pneumatic system that is still functioning is not automatically a problem. The problem is when it becomes invisible to facility management because nobody on the current team knows how to read a pneumatic schematic, and deferred maintenance on the compressed air supply compromises the whole system. Detroit and Dearborn both have commercial buildings in this category, and Wayne County has more pneumatic-controlled square footage than most facility managers in the area realize.
The path forward for pneumatic-controlled buildings is not always a full rip and replace. Direct digital control overlays can bring pneumatic-controlled zones under BAS supervision without replacing every pneumatic actuator in the building. A phased overlay approach typically costs 30 to 50 percent less than a full DDC retrofit and produces most of the energy visibility and control benefits of a new system. The overlay hardware runs on BACnet or LonWorks, which means a vendor neutral contractor can service it without an OEM restriction.
For newer Detroit and Troy commercial buildings that run Metasys or Niagara, the vendor neutral path is straightforward. The more interesting engineering case in Michigan is the building that has both: a 1970s tower with pneumatics in the lower floors and a Niagara overlay in the upper floors installed in 2008, where the two systems have never been properly integrated and the facility team is managing them as two separate programs.
Phased BAS Retrofit Without a Full Rip and Replace
The most common objection to improving an aging BAS is capital cost. A full Niagara or Metasys replacement on a 100,000 square foot office building in Detroit can run $400,000 to $800,000 depending on point count and infrastructure condition. That kind of capital decision takes two budget cycles to approve and a year to implement. Most facility managers do not have either.
A phased retrofit operates differently. The goal is to add visibility and control where the return is highest, one system or zone at a time, without replacing the underlying infrastructure. A typical phased engagement starts with a BAS audit that scores systems by age, fault frequency, and energy impact. The top two or three systems are addressed in year one: typically economizer controls, occupied setpoint schedules, and alarm rationalization. Those changes alone frequently reduce HVAC energy consumption by 8 to 15 percent without replacing hardware.
Year two addresses the next tier: adding trend logging to chiller or boiler plants that currently run blind, integrating lighting controls into the BAS schedule, and replacing the oldest pneumatic zones with DDC overlays in the highest-use areas. By year three, the building has a functioning BAS that a vendor neutral contractor can service, and the cumulative capital expenditure is a fraction of what a full replacement would have cost. The DTE commercial rebate catalog includes incentives for BAS controls retrofits that qualify, which reduces the out-of-pocket cost on the controls portion of a phased retrofit.
How Samco Services BAS and BMS Across Southeast Michigan
Samco Facilities Maintenance has been servicing commercial HVAC and building systems across Wayne, Oakland, Macomb, and Washtenaw counties since 1997. Our technicians are EPA 608 Universal Certified and NATE certified. We carry a BBB A+ rating and our field team works on Metasys, Niagara, Tridium, and legacy pneumatic systems without OEM restriction.
Our BAS service engagements start with a system audit: controller hardware inventory, software version check, alarm database count and age, trend log configuration, and occupied schedule review. We document what the system is doing versus what it should be doing and present a written gap report with prioritized recommendations. For a Livonia multi-tenant office complex we started servicing in 2016, the audit found 23 permanently acknowledged alarms that had been suppressed instead of resolved, two occupied schedules running on a 2009 tenant’s calendar, and three economizer actuators that were locked closed. None of those items required new hardware to fix. They required a technician with BAS programming access and two days of work.

Frequently Asked Questions
What is a vendor neutral building automation contractor?
A vendor neutral BAS contractor services, programs, and monitors building automation systems across multiple platforms without being tied to a single manufacturer’s service contract. Rather than requiring you to replace your existing Metasys or Niagara system to get service, a vendor neutral contractor works on the platform you already have using open protocol access. This typically costs significantly less than an OEM service contract for equivalent or broader scope.
Can Samco service Metasys, Niagara, and other BAS platforms?
Yes. Samco’s technicians service Metasys (BACnet), Niagara Framework on Tridium hardware, legacy pneumatic systems, and direct digital control overlays across Southeast Michigan. We do not require OEM service agreements to access or program these systems. Our scope includes alarm rationalization, trend log review, setpoint and schedule updates, controller firmware updates, and point verification for all supported platforms.
Is a phased BAS retrofit cheaper than a full rip and replace?
For most buildings, yes. A phased approach that adds DDC overlays to the highest-priority zones and addresses alarm rationalization, schedule optimization, and economizer controls in year one typically costs 30 to 50 percent less than a full system replacement while delivering most of the energy visibility and control benefits. The remaining phases are funded in part by the energy savings from the first phase, making the total capital commitment more manageable across budget cycles.
Do you handle BAS alarm and trend log tuning?
Yes. Alarm rationalization and trend log review are standard services in Samco’s BAS maintenance contracts. We review the full alarm database, identify permanently acknowledged or suppressed alarms, and resolve root causes rather than continuing to suppress notifications. Trend log configuration review ensures that the data the BAS is capturing matches the equipment conditions that matter for energy management and fault detection in your facility.
