Reconstruct supports multiple workflows that cater to different users in the construction process. This article explains how to use the tools and features in Reconstruct cloud-based platform to create 3D reality models of the existing conditions of your construction site and compare them to design models in order to identify quality issues. This workflow enables users to:
- Document the existing conditions of the construction site by generating point clouds and reality models from drone images or 360 videos
- Use Reconstruct Capture App to capture 360 videos and images of the construction site and place them on PDF drawings
- Perform measurements on BIM and reality
- Upload design models in PDF or BIM formats and then compare them to reality models to perform QA/QC
- Use Pins, Viewpoints, Markup, and Snapshot tools in Reconstruct to highlight identified quality issues and keep track of their progress
What You Need
To get started with this workflow you need the following:
- BIM models of your project
- One or more of the following:
- Drone images of the exterior of your project
- You can fly the drone in-house, by training one of your project engineers
- You can outsource the capture to a third party capture provider
- 360 videos of the interior or exterior of your project
- You need to purchase a 360 camera and stabilizer
- Drone images of the exterior of your project
Getting Started
Once you have your purchased your equipment, you should follow the steps below to get started with this workflow:
Step #1: Login to Reconstruct on your computer
If this is your first time to use Reconstruct, then you will need to create an account, login, and go to the Data Manager. It is important to do this step on a computer using Google Chrome or Mozilla Firefox web browsers.
Step #2: Upload BIM models of your project
Reconstruct supports more than 60 formats of BIM files. You should upload your BIM files into Reconstruct Data Manager.
Step #3: Assign locations
Once your BIM models are uploaded to Reconstruct you should create locations and identify bounding boxes for each of them.
Step #4: Download and install Reconstruct Capture app on your iOS device
Click here to download Reconstruct Capture app from the Appstore. Once the app is installed on your iOS device, use your Reconstruct username and password to login to the app.
Step #5: Connect your 360 camera to the app
Once logged in to the app, you should connect your 360 camera by following the instructions here.
Step #6: Capture 360 videos of your indoor and outdoor spaces
Use the Reconstruct Capture app to guide you through capturing 360 videos of your projects. Also, check our guidelines for 360 video capture.
Step #7: Stitch the captured 360 videos on your computer or on Reconstruct
The raw format of the 360 videos usually includes one or two files in INSV or other proprietary formats. Once you captured your 360 videos, you will most likely need to stitch them and convert them into MP4 format or directly upload it to Reconstruct to automatically convert it to MP4.
Step #8: Upload 360 videos and process point clouds
Once your videos are captured, stitched, and converted into MP4 format, you should upload them into Reconstruct and process them to create point clouds. Click here for more information.
Step #9: Capture Drone images
If you are planning to use drones to capture the core and shell phase of your project, then you need to follow our guidelines to achieve a good quality capture.
Step #10: Upload and process Drone images
Once you captured drone images according to Reconstruct guidelines, you should upload them and process them into point clouds.
Step #11: Align point clouds to BIM
Once the point clouds are processed and ready, you will receive an email from Reconstruct. Follow the instructions here to align your point clouds to the BIM models you uploaded in Step #2.
Step #12: Compare point clouds and BIM (Using BIM overlay)
After your point clouds are captured, processed, and aligned, they are ready for you to view and compare with BIM by navigating our 3D Viewer.
Step 14: Identify any quality issues using Pins
Once you identify quality issues in your project by comparing BIM and point clouds, you can keep track of these issues using the Pins tool in Reconstruct.
Step #13: Repeat the capture process if needed
You can repeat steps 6 to 14 as needed (e.g. every week) to prepare for coordination meetings and keep your project up-to-date.
