At Saltus Construction Monitoring Services, we use cutting-edge tools to ensure that buildings surrounding an active construction site remain protected during various activities (such as excavation, underpinning, and demolition) that could contribute to potential damage.
One of the most powerful tools in our toolkit is the Automated Motorized Total Station (AMTS).
Below, we answer some of the most commonly asked questions about this advanced surveying technology.
What is an Automated Motorized Total Station (AMTS)?
An Automated Motorized Total Station (AMTS) is a sophisticated optical surveying instrument used in construction and structural monitoring to track and record the movements of buildings, tunnels, bridges, and other structures. These systems work by measuring angles and distances to reflective targets (typically prisms) that are strategically installed on critical points of a building or infrastructure. What makes AMTS technology especially valuable is its ability to automatically and continuously collect data with great accuracy, even in complex urban environments.
Unlike traditional manned total stations that require an on-site operator to manually align and record data at scheduled intervals, AMTS devices are fully automated and motorized, allowing for remote operation and real-time data transmission. This means that once the system is set up, it can run autonomously, monitoring movements 24/7 without the need for a human presence on-site.
Additionally, AMTS systems are often integrated with automated alert features, so if any displacement or structural shift exceeds a predefined threshold, stakeholders are notified immediately. This proactive monitoring capability enhances safety, supports compliance with city regulations, and minimizes potential damage to surrounding buildings.
For cities like New York, where buildings and structures are densely packed and construction activity can affect multiple properties at once, AMTS offers a reliable, efficient, and cost-effective solution for long-term optical structural surveying.
What are the Key Advantages of Automated Motorized Total Stations in Construction Monitoring?
There are numerous benefits to using Automated Motorized Total Stations (AMTS) for optical structural surveying, especially in the complex and fast-paced construction environments of cities like New York.
Below are the most significant advantages of automated motorized total stations when incorporated into a comprehensive monitoring strategy:
Real-Time Monitoring
One of the most important advantages of AMTS is its ability to deliver continuous, real-time monitoring of structural movement. This means that any displacement, however minor, can be detected as it occurs. For construction projects taking place near existing buildings, this data is critical for identifying early signs of settlement, tilt, or deformation that may compromise structural integrity. Real-time insights empower engineers, contractors, and building owners to take immediate corrective actions, reducing the risk of costly damage or safety incidents.
Remote Access
AMTS systems can be operated and monitored remotely, which significantly reduces the need for frequent site visits. Once the system is installed, Saltus technicians can access the data and adjust settings from a centralized location. This not only improves response times but also minimizes the logistical challenges of accessing tight or hazardous construction zones. Remote monitoring is particularly useful in dense urban environments where space is limited and site access is restricted.
Accuracy
AMTS technology offers millimeter-level accuracy, which is essential in environments where even the slightest structural shift can have major consequences. This level of accuracy allows Saltus to detect minute changes that might go unnoticed with manual tools or less advanced technologies. In major cities, where construction often takes place just inches away from historic buildings, infrastructure, or public walkways, this level of accuracy provides peace of mind and helps prevent long-term issues.
Reduced Human Error
By automating data collection, AMTS significantly reduces the risk of human error. Manual total stations rely on the skill and consistency of a human operator, which can introduce variability in measurements over time. AMTS removes this variable by using pre-programmed routines and precise instrument alignment, ensuring consistent, repeatable, and unbiased data collection across the entire monitoring period.
Time and Cost Efficiency
Although the initial setup of an AMTS system may be more involved than a manual solution, the long-term time and cost savings are substantial. Automated systems reduce the need for on-site personnel, eliminate redundant tasks, and streamline reporting workflows. Over the course of a multi-month or multi-year project, these efficiencies can lead to significant reductions in labor costs and administrative overhead.
Custom Alert Systems
AMTS systems used by Saltus can be programmed with custom alert thresholds based on each project’s specific risk profile. When a measurement exceeds these thresholds, such as a vertical shift, horizontal displacement, or tilt, an alert is automatically triggered and sent to designated project stakeholders. This allows for proactive, rather than reactive, decision-making and ensures that any potential threats to structural stability are addressed before they become emergencies.
As you can see, the advantages of automated motorized total stations extend far beyond convenience. They represent a smarter, safer, and more efficient way to monitor structural integrity during active construction. At Saltus Construction Monitoring Services, we leverage these tools to protect buildings, support engineering decisions, and help clients meet regulatory requirements with confidence.
How Does an AMTS System Compare to Manual Total Stations?
While both manual total stations and Automated Motorized Total Stations (AMTS) are valuable tools in construction monitoring, they serve different purposes and offer distinct advantages depending on the project’s complexity, duration, and environment.
When to Use Manual Total Stations
Manual total stations have long been a standard in optical structural surveying. They are effective for many monitoring applications, especially when:
- The project duration is short.
- Budget constraints are a major factor.
- High-frequency data collection is not required.
- Site access is easy and consistent.
However, manual systems require a trained surveyor to be physically present on-site to operate the instrument, align with the prisms, and record measurements. As a result, data is typically only captured during scheduled intervals (daily, weekly, or as needed). This intermittent monitoring means that subtle structural changes or sudden movements occurring between check-ins may go undetected.
When to Use Automated Motorized Total Stations
By contrast, AMTS technology removes the limitations of manual data collection by delivering automated, continuous monitoring. Once installed and configured, AMTS units can collect and transmit data 24/7 without requiring a surveyor to be on-site. This provides a much clearer and more complete picture of how structures behave over time—especially during critical construction phases like excavation, pile driving, or foundation work.
In dense urban environments where adjacent buildings are often located within inches of active construction zones, AMTS solutions offer:
- Higher levels of accuracy.
- Higher data frequency.
- Improved safety through remote operation.
- Faster detection of structural shifts.
Ultimately, the choice between AMTS and manual total stations depends on your project’s unique requirements. At Saltus, we evaluate every site individually to determine the best-fit solution, balancing accuracy, budget, and risk to provide dependable structural monitoring that protects both property and public safety.
Why is AMTS Especially Useful in Cities?
Cities have dense infrastructure filled with buildings and structures that are crammed among the busy streets. These layouts make construction monitoring particularly challenging.
AMTS helps overcome these challenges by:
- Providing constant surveillance without requiring physical access to sensitive areas.
- Capturing even the slightest movements in real time.
- Minimizing disruption to surrounding properties and communities.
- Helping ensure regulatory compliance and avoid costly damage claims.
At Saltus, we understand the complexities of city construction projects and tailor our monitoring solutions accordingly.
Does Saltus Use AMTS Technology in Its Construction Monitoring Services?
Yes. At Saltus Construction Monitoring Services, we leverage both Automated Motorized Total Stations and manual total stations depending on the unique needs of each project. For long-term and high-risk construction zones, we often recommend AMTS for its accuracy, automation, and reliability. For smaller or less complex sites, a manual total station may be appropriate.
Our optical structural surveying services are always customized to the specific project and compliant with New York City regulations, including DOB TPPN 10/88, ensuring full legal and structural integrity throughout construction.
How Do AMTS Monitoring Systems Improve Construction Project Outcomes?
In addition to the convenience that they offer, Automated Motorized Total Stations (AMTS) also directly contribute to better project performance, greater safety, and long-term structural integrity. By delivering real-time, highly accurate data on structural movements, AMTS technology plays a significant role in helping project teams stay ahead of potential issues and maintain control over evolving site conditions.
Here’s how AMTS improves outcomes across the board:
Reduces Risk to Neighboring Buildings and Structures
One of the primary goals of optical structural surveying is to protect nearby structures from unintended damage during construction. These buildings are often decades or even centuries old, with varying degrees of structural stability. AMTS allows engineers and developers to detect even the slightest movements early, giving them the opportunity to adjust construction methods or halt operations to prevent damage. This early warning capability dramatically reduces the risk of foundation settlement, façade cracking, or worse.
Improves Construction Safety
AMTS systems contribute to a safer work environment by continuously monitoring critical structures and alerting teams when movement exceeds safe thresholds. Whether the concern is a retaining wall, an underpinning operation, or a neighboring building’s foundation, AMTS systems provide real-time data that informs safety decisions. These insights help construction managers take prompt action, protecting not just property but also the workers and pedestrians nearby.
Supports Faster and More Informed Decision-Making
With real-time access to accurate measurement data, project stakeholders no longer have to wait days or weeks for manual survey reports. This immediacy empowers engineers, contractors, and owners to make faster, data-driven decisions that keep the project on track. Whether it’s modifying excavation methods, adjusting shoring systems, or responding to unexpected movement, AMTS helps teams react with agility and precision.
Ensures Compliance with Local Regulations and Engineering Standards
Construction monitoring in NYC is heavily regulated, with requirements such as DOB TPPN 10/88 mandating the protection of adjacent structures. AMTS helps developers meet these requirements by providing consistent, verifiable data that demonstrates compliance with city codes and engineering best practices. This not only reduces the risk of violations or fines but also offers valuable documentation to support insurance claims or legal matters, if needed.
Contributes to Safer, More Resilient Urban Infrastructure
At the broader level, the advantages of automated motorized total stations help create a more sustainable and resilient urban environment. By minimizing the risk of structural damage during construction and reducing the likelihood of long-term issues, AMTS supports the longevity and stability of both new and existing buildings. It also helps cities grow smarter by balancing progress with preservation.
Clearly, AMTS technology enhances the overall success of construction projects by improving safety, compliance, responsiveness, and reliability. At Saltus Construction Monitoring Services, we integrate AMTS into our optical structural surveying services to help construction teams protect people, property, and peace of mind.
