PAL Defects
Read full descriptionHide full description
PAL Defects is the tool from Projects Asia Group Company Limited for communication between inspector and contractor for managing and solving the issues in construction sites. A site inspection usually ends with a note in a book, a photo on someone's phone, and a conversation nobody wrote down. PAL Defects keeps the whole loop — raise, fix, verify, close — in one place, so every defect has an owner, a location, and a record. THE INSPECTOR - Raise a defect in a few taps: subject, type of work, and a written description. - Photograph the problem and mark it directly on the image, so the contractor sees exactly what you mean. - Record a voice note when typing on site is not practical. - Pin the exact location on the project keyplan — building, floor, area and room. - Review rectified work and approve or reject it, with a photo and a reason attached. THE CONTRACTOR - See every defect raised against your work, with the original photo, the marked-up image and the location. - Filter by building, floor and area to clear one zone at a time. - Submit rectified work with an "after" photo for the inspector to verify. - Compare before and after side by side. THE PROJECT TEAM - A dashboard with total, rectified and remaining defects, and the percentage still outstanding. - Filter and search the full defect list. - Every defect carries a reference number, dates and the people involved. BUILT FOR SITE CONDITIONS - Works offline. Defects, photos and voice notes are saved on the device and sync when you are back on a connection. - Choose which keyplan disciplines to download, so the first sync pulls only the drawings you actually need. - Sign in with Google, or with your email and PIN. PAL Defects is for construction professionals — inspectors, contractors, project managers and directors.
