One of the biggest problems with of document management with construction jobs is storage space for all the required drawings, photos and documents. For small scale jobs like the design and construction of a simple bridge the allocated free storage allowance of 5Gb that comes with Google Drive should be more than sufficient. However, for larger construction schemes like a road with multiple bridges, 5Gb storage would be devoured quite quickly particularly if photos and videos are being shared in the cloud. Hence, more memory will be required which may be purchased for a monthly rate
