The cloud-based platform facilitates collaboration and integrates with accounting systems for efficient project management.

Trimble AccuBid is a robust estimating software primarily designed for electrical contractors, with strong capabilities for building automation systems (BAS) through its extensive database of low-voltage components, controllers, sensors, and wiring assemblies. It enables detailed digital takeoffs, labor and material costing, and bid generation, supporting accurate estimates for HVAC controls, lighting, and security integrations. The software integrates with Trimble's ecosystem for enhanced project management and real-time collaboration.

PataBid Quantify is a cloud-based estimating software tailored for low voltage contractors, including building automation systems (BAS), fire alarms, and security. It enables digital takeoff from PDFs and CAD files, leverages a database of over 30,000 items and assemblies with proprietary MEPA labor units for accurate costing, and generates professional proposals. The platform emphasizes speed and precision in bid preparation for BAS projects involving controls, HVAC integration, and related low voltage work.

Success Estimator X is a comprehensive estimating software primarily designed for electrical contractors, offering digital takeoff tools, a vast database of items and assemblies, and automated labor calculations. It supports detailed cost estimating for wiring, controls, and low-voltage systems, making it adaptable for building automation projects involving HVAC controls, lighting, and security integrations. While not exclusively tailored for BAS, its robust electrical focus enables accurate bids for automation-related electrical work, with features for change orders and job costing.

TurboBid is a cloud-based estimating and takeoff software primarily designed for electrical contractors, enabling digital plan takeoffs, material and labor calculations, and professional bid generation. For building automation estimating, it excels in handling low-voltage wiring, devices, and controls through customizable assemblies and databases, though it requires user setup for BAS-specific components like DDC panels or sensors. It streamlines workflows from blueprint analysis to client proposals, supporting collaboration and integrations with accounting tools.

Groundplan is a cloud-based floor planning and takeoff software designed for quick digitization of 2D plans from PDFs, sketches, or DWGs, enabling measurements of areas, lengths, and counts for construction estimating. In the context of building automation estimating, it supports basic quantity takeoffs like room zoning areas, wiring run lengths, and fixture counts from floor plans. While efficient for surface and linear measurements, it falls short on specialized BAS features like device libraries or labor calculations. Its AI-driven plan recognition streamlines initial setup for estimators working with architectural drawings.

ProEst is a cloud-based construction estimating software designed to streamline the bidding process for trades like electrical, mechanical, and plumbing, making it adaptable for building automation projects involving controls, wiring, and HVAC systems. It features digital takeoff tools, real-time material and labor pricing, and customizable assemblies to generate accurate estimates quickly. The platform integrates with accounting software and offers mobile access for on-the-go bid management, though it requires setup for building automation-specific item libraries.

Stack (stackct.com) is a cloud-based takeoff and estimating software tailored for construction trades, including building automation, enabling rapid digital measurements from PDFs and CAD files. It automates quantity takeoffs, generates detailed estimates, and supports real-time team collaboration for accurate bidding on BAS projects involving controls, wiring, and HVAC integration. The platform integrates with tools like Procore and QuickBooks to streamline workflows from estimate to project handover.

PlanSwift is a desktop-based on-screen takeoff and estimating software designed for construction professionals to perform digital measurements directly from PDF, CAD, or scanned plans. It excels in quantifying materials like conduit runs, devices, wiring, and panels, which can be adapted for building automation systems (BAS) estimating through custom assemblies and formulas. While versatile for various trades, it requires user-defined libraries for BAS-specific components such as controllers, sensors, and BACnet devices.
