Building Start vs Proof TAB

Building Start is a field services platform used in construction and engineering to perform centralized test plan authoring and management and push the test plan from the cloud to field devices to perform on-site field testing digitally. Once a field technician has been assigned a project, they can receive the project on their field device and perform the test plan and responses offline and synchronize them back into the cloud when they complete their work for the day. Building Start is widely used in the construction industry with over 30,000 construction projects digitally captured in such efforts as Test, Adjust & Balance (TAB), Building Startup, Building Commissioning (LEED, Green Building,etc) and Energy Audits.

Proof helps field technicians and engineers perform Testing, Adjusting and Balancing (TAB) and Commissioning (Cx) work more efficiently, accurately, and professionally on site. Built to work seamlessly with its desktop companion, the app enables iPhone users to capture data in the field and sync it automatically to the desktop for streamlined review, reporting, and project coordination. Designed around real site needs and aligned with international standards, Proof supports a wide range of workflows, including: Packaged Units Air Handling Units (AHUs) Fresh Air AHUs Chillers and hydronic water systems Customizable forms Checklists Issue logs Site observations With Proof, teams can reduce paperwork, improve consistency, and deliver clearer, faster, and more reliable TAB and Cx documentation from site to office. A slightly more breakthrough marketing version: Proof transforms how TAB and Commissioning teams work on site. It gives technicians and engineers a faster, smarter way to collect, manage, and synchronize field data while working in full coordination with the desktop platform. Data captured on iPhone is automatically synced, helping teams move seamlessly from field execution to office review and final reporting. Developed to meet real project-site demands and support internationally recognized workflows, Proof covers key equipment and processes such as Packaged Units, AHUs, Fresh Air AHUs, chillers, water systems, custom forms, checklists, issue tracking, and site observations. From field data capture to final documentation, Proof helps deliver better accuracy, stronger consistency, and a more professional TAB and Cx process.
