The FieldAR mobile app enables your entire project team to effortlessly view the latest BIM/3D design models overlaid onto your real-world construction site using precision augmented reality. FieldAR’s primary objective is to provide a central source of truth for quality assurance, quality control, and the precise locations of installed systems and equipment at active or completed construction sites. With FieldAR, users can visualize BIM/3D models overlaid onto real-world construction sites with a simple, single-tap operation, making it easy for even non-tech-savvy field staff to see the exact locations of designed building system elements. BIM/VDC Managers can leverage the FieldAR plugins to easily upload and update models directly to the FieldAR mobile app, ensuring that the entire team is working with the most current information. Additionally, markups captured by team members using the mobile app on-site can be viewed back in the BIM platforms through the FieldAR plugins, creating a seamless workflow of information between off-site BIM management and the construction site. FieldAR empowers your team to save money, reduce re-work, and optimize project schedules while enhancing productivity and collaboration. FieldAR supports 8 languages: English, Spanish, French, German, Japanese, Polish, Russian, and Chinese (zh-Hans). Core AR features: -Single-tap model loading with automatic alignment to the real world -BIM/3D models are automatically downloaded and aligned when users scan QR code targets at your physical jobsite -AR Markups tool that enables your team to flag issues while on site -Markup data can be viewed in the mobile app and in the FieldAR plugins for Navisworks Manage and Revit -AR Measurements tool that can measure model elements and/or real world elements -Built-in camera for taking photos and recording video -Mesh scanner for capturing meshes of the real world -Scanned meshes can be added to markups, and are automatically aligned to the model -Scanned meshes can be viewed in the mobile app and in the FieldAR plugins for Navisworks Manage and Revit -AR opacity adjustment to see more/less of the 3D model or the real world -AR sectioning tool to “slice” the 3D model -BIM/3D model details viewer for viewing model element details -Model elements can be hidden, isolated, and highlighted -AR floor plan mini-map that can be used to visualize where the user is at the jobsite -AR Wireframe mode to see the wireframe of the model -AR occlusion culling that will allow real-world elements to show through the model For BIM/3D model managers: -Upload/update 3D models directly from the mobile app or FieldAR plugins for Navisworks Manage and Revit -Advanced 3D model viewer for viewing the model when away from the jobsite -Generate custom-branded QR code targets that can be printed and installed at the physical jobsite -QR code target placement tool in AR -Cloud-based spatial anchor placement tool that helps automatically align the model when users view the model in AR -View markup sketches, details, mesh scans, and conversations directly in the mobile app and in the FieldAR plugins for Navisworks Manage and Revit -Upload floor plans, and locate models on the floor plan AR Project Management: -View/edit your full project list in your Dashboard -Navigate models within each project -View all project activity, i.e. model updates, markup comments, etc. -Easily create new projects and upload models from the mobile app

About

Hydrant Flow Test Calculator

This tool simplifies hydrant flow testing by calculating total GPM from pitot pressures. It allows for outlet settings, flow extrapolation with a Supply vs Demand curve, and plotting demand points for PASS/FAIL results. Save test data with location and project details for future reference.

Highlights
  • Calculate total GPM from pitot pressures
  • Configure outlet diameter and hydrant coefficients
  • Extrapolate flow with Supply vs Demand curve
  • Plot demand points for PASS/FAIL analysis
  • Save test results with date, time, and project info
  • Log hydrant locations via GPS
  • Review saved test history
Features
Read full description

Hydrant Flow Test Calculator is a field-friendly calculation and reporting tool for fire protection professionals, engineers, inspectors, contractors, and AHJs who need to evaluate and document hydrant flow test results. The app helps calculate hydrant flow from field readings, compare available water supply against system demand, estimate downstream friction loss, and export professional PDF reports. Key features: • Calculate hydrant flow using static pressure, residual pressure, pitot pressure, outlet diameter, and discharge coefficients • Calculate total test flow and flow at a target residual pressure • Compare available supply against system or pump demand • Review demand pass/fail results with available pressure and safety cushion • View Supply vs Demand graph with demand point legend • Save completed test records to History • Add project information including associate, project number, project location, test hydrant tag, and flow hydrant tag • Optionally capture test hydrant and flow hydrant coordinates • Attach an image to a saved test record • Export PDF reports with project details, test summary, demand results, graph, location details, friction loss results, and attachment • Estimate friction loss using pipe product, nominal pipe size, inside diameter, pipe length, C-factor, elevation, minor loss, and device/backflow loss • Supports US and SI flow display The Friction Loss tool includes pipe product and nominal pipe size selection with automatic inside diameter lookup. Elevation guidance helps users enter positive values for uphill and negative values for downhill conditions. Hydrant Flow Test Calculator is designed to make field calculations faster, improve documentation consistency, and help organize hydrant flow test information in one place. This app is intended as a calculation and documentation aid. Users are responsible for verifying all inputs, assumptions, calculations, and results according to applicable codes, standards, project requirements, and professional judgment.
