Trimble adds AI-driven takeoff and estimating tools for MEP contractors

The pre-construction phase of any major project often dictates its financial success or failure. Estimating mechanical, electrical and plumbing requirements is notoriously complex. It involves interpreting intricate drawings, counting countless symbols and calculating lengths of materials with precision. For years, this process has relied heavily on manual effort, leaving estimators bogged down in repetitive tasks rather than strategic planning. Trimble has now introduced new artificial intelligence capabilities across its estimating solutions to address these exact inefficiencies.

The integration of artificial intelligence into Trimble's Accubid Anywhere software marks a significant shift in how contractors approach bidding. By automating the most tedious aspects of the takeoff process, the technology allows teams to increase their bid volume without necessarily expanding their headcount. This development is particularly relevant for project delivery professionals who are constantly seeking ways to improve accuracy and reduce the time spent on initial project assessments.

One of the most time-consuming elements of the estimating process is the initial setup. Before any counting or measuring can begin, estimators must carefully review document uploads, identify the correct scales and name the various plan sets. This foundational work is critical, yet it adds little strategic value to the overall bid.

Trimble's new artificial intelligence tools tackle this bottleneck directly. The software can instantly identify and set the correct scale and name across entire plan sets. This means estimators can move from the document upload stage to quantity takeoff in a matter of seconds. By removing this administrative burden, teams can allocate their time to more complex analytical tasks that require human judgement.

Counting symbols on construction drawings is a classic example of a necessary but highly repetitive task. Receptacles, switches, light fixtures and other components must be tallied accurately to ensure a precise estimate. Historically, this has involved estimators manually scanning documents and marking each item, a process prone to human error, especially under tight deadlines.

The updated software uses artificial intelligence to interpret construction drawings, automatically recognising, labelling and counting these symbols. According to Trimble, the automated takeoff feature has already detected more than three million symbols, thus reducing the time needed for manual recognition by more than half. The system acts as an intelligent collaborator, handling the heavy lifting of data extraction while leaving the final review to the human expert.

Length-based takeoff, particularly for conduit measurement, presents another significant challenge in estimating. Calculating linear footage requires accounting for vertical rises and drops, which can be difficult to interpret accurately from two-dimensional drawings. Errors in these calculations can lead to significant discrepancies in material orders and project costs.

To address this, Trimble has introduced an auto-routing feature that calculates conduit linear footage automatically. This tool eliminates much of the manual effort involved in these measurements. By providing a more accurate baseline for material requirements, the software helps contractors build more reliable bids and avoid costly overruns during the construction phase.

Beyond automating specific tasks, Trimble has integrated an AI Smart Assistant directly into the Accubid Anywhere platform. Built on the company's agentic artificial intelligence platform, this assistant allows users to interact with their estimates using natural language queries.

Estimators can ask the assistant to research historical material pricing or compare complex estimate versions without needing to navigate through multiple menus or databases. The always-on support function improves overall efficiency. Trimble reports that users experience average time savings exceeding 80% for these specific research and comparison tasks. The assistant helps users quickly access relevant data, enabling them to make informed decisions faster.

While the automation capabilities are extensive, Trimble emphasises that these tools are designed to support, not replace, the estimator. The concept of the "human in the loop" remains central to the software's design. Estimators are expected to use their own quality assurance processes to review the outputs, identify any false positives and validate the data.

The collaborative approach ensures that the final estimate benefits from both the speed of artificial intelligence and the nuanced judgement of an experienced professional. Real-time input from users also helps the model learn and improve its performance over time.

"The estimators on my team who are heavy users of Trimble AI tools cut overall estimating time significantly, which leads to more jobs, more projects and better accuracy," said Tim Jonas, executive director of estimation at Kidwell Electric. "It's really more of a review process for the estimator that allows them to focus on higher-payoff activities rather than an actual takeoff process."

• The automation of pre-takeoff setup allows estimators to transition from document upload to quantity takeoff almost instantly.

• Artificial intelligence tools can reduce the time required for manual symbol recognition by more than 50%, improving both speed and accuracy.

• Automated routing features simplify the calculation of linear footage, providing more reliable data for material orders.

• Natural language queries via the Smart Assistant significantly reduce the time spent researching historical pricing and comparing estimates.

• The technology is designed to augment human expertise, shifting the estimator's role from manual data entry to strategic review and validation.
