Our Products

Building Start has cloud-based, mobile software for the Test & Balance contractor.  AiRNAB is Test & Balance software setup with the TAB contractor in mind, offering a way to digitally record all of your TAB measurements easily with the Building Start Field Tool app using your smart phone, tablet or laptop.  Our Field Tool is a stand-alone application that works off-line until you need to sync your project data to our cloud-based server.  Eliminate the redundant data entry that is common with a paper-based documentation process and submit your final report more quickly.  AiRNAB helps your TAB technicians easily record all of their air balancing and water balancing data and sync that information as often as needed, offering a seamless data sharing experience with the office.
AiRNAB also has a powerful Issue Management tool that allows your TAB technicians to quickly and easily document deficiency’s they encounter while testing and balancing a project.  Record, track and manage deficiency’s easily with one issue log for each project regardless of how many TAB technicians you have working.  Regularly follow up with other sub-contractors and get your punch lists addressed in a more timely fashion.

Building Test from Building Start is a digital system for collecting field data. Building Test lets building commissioners create and manage their commissioning test plans within an enterprise database.

Once a test plan is authored, commissioners and project managers can use Building Test to assign the plans to members of the commissioning team to be completed digitally on smart devices in the field. All data recorded in the field is automatically stamped with a date, time and username, giving commissioners a full, chronological audit trail of the testing process.

And because Building Test is digital, it is easy to reuse test plans on future projects that have similar equipment and systems.

Turning a paper-heavy process fully digital, paperless, and transparent? A smart, cost-effective, time-saving solution.
