Asta Power Project
Asta Power Project is the preferred scheduling tool across UK residential, commercial, and heritage construction — used extensively on JCT contracts by tier-one contractors and specialist subcontractors. Deltime builds and maintains Asta programmes with full logic, resources, and progress tracking.
Why Asta on UK Building Projects
Asta Power Project has established itself as the preferred scheduling tool across UK residential, commercial, and mixed-use construction. Its Gantt-focused interface, compatibility with JCT programme requirements, and widespread adoption by tier-one contractors make it the practical default on most building contracts in the UK private sector.
JCT Clause 2.9 Compliance
Under JCT, the master programme must show the order and timing of execution of the Works. Deltime structures every Asta programme to meet this requirement with a logic-linked network, a clear critical path, and a method statement — not just a bar chart — so it carries weight in any EOT or loss & expense assessment.
Logic, Float & Critical Path
Deltime builds Asta programmes with full predecessor/successor logic, ensuring the critical path is genuine and defensible. Float ownership is established in the programme narrative from the outset — a critical step under JCT that prevents the Employer claiming Contractor float for their own delay events.
Progress Tracking & Updates
Monthly Asta programme updates are issued formally to the Employer's Agent — showing actual progress, revised Completion Date forecasts, and the effect of any instructions or Relevant Events that have occurred in the period. Each update is accompanied by a concise narrative report.
EOT & Loss and Expense Support
When Relevant Events arise under JCT, Deltime uses the Asta programme to quantify their time impact contemporaneously — building the evidential record needed for a credible EOT application and linking the delay period to the claimed loss and expense prolongation costs.
Heritage & Complex Projects
Asta's flexibility makes it well suited to heritage conversions and complex phased works where sequences are difficult to predict and programmes require frequent revision. Deltime has used Asta on projects including Lots Road Power Station and other Listed Building conversions where sequencing uncertainty is a significant planning challenge.
