Validation - Control - Assurance

AESCO developed the Construction Quality Validation Inspection and Testing Plan currently used on the I-405 Improvement Project. The program links our in-house Smart PDF forms to our ShareFile Cloud system. The program is used to track Daily Inspection Reports, Daily Traffic Inspection Reports (MOT), Quality Validation Checklists and Critical Activity Point Checklist/Sign-off forms for various construction procedures.

AESCO Employees use digital tablets in the field, where they can select an updated form, review project documents, take photos, and generate redlines on the plan sheets. Daily inspection reports are uploaded daily to AESCO’s ShareFile Cloud, where the can be reviewed in real time and submitted to the client.
