Aphex is the proven construction delivery platform. Site teams use it to plan the weeks ahead, run daily coordination and capture the record of what happened, all from one live plan. Think about everything it takes to run a site: the lookahead, staging plans, crew briefs, progress tracking and the daily diary. On most sites that's spread across spreadsheets, whiteboards and WhatsApp. The plan and what's actually happening drift apart, and the team absorbs the avoidable delay and cost. Aphex is one place to run the site. The mobile app puts it in your pocket. SEE TODAY'S WORK FROM THE LIVE PLAN • Your tasks come straight from the lookahead the whole team builds in Aphex • See your work, your team's or everything across the project, filtered by subcontractor, shift, location or user • See where work is happening on the site map, spot clashes and bring in your ArcGIS layers TRACK PROGRESS AS IT HAPPENS • Thumbs up when a task is on track, thumbs down to log a delay and the reason • Log progress as % complete, or in units like metres of pipe laid • Updates reach the office straight away, so the morning coordination meeting starts from where things really stand • @mention colleagues and get notified when work that affects you changes THE SITE DIARY THAT WRITES ITSELF • Talk or type through the shift, and add photos, voice notes or a snap of a handwritten page • Record labour, plant and materials against the tasks they belong to • Aphex compiles everything into a draft that starts from the day's plan. Review and approve it in under five minutes • Keep capturing offline. Notes and photos sync when you're back in signal A RECORD YOU CAN STAND BEHIND Every photo, note and progress update is linked to the task it relates to. When a delay becomes a claim months later, the record is already there. Trusted by 100+ Tier 1 contractors on infrastructure, rail, energy, nuclear and major building projects.
