Construction Programme & Gantt Chart Software

The Problem

Programmes live in MS Project on one laptop, disconnected from what is actually happening on site. By the time slippage is noticed it is too late to recover, and there is no clean record to evidence delay or defend an extension of time.

What Changes

One live programme per project — Gantt, critical path and lookahead — that the whole team can see, with progress tracked against a baseline so delay is visible early and evidenced properly.

How It Works

From a master programme to a weekly lookahead, keep delivery on track and delay evidenced.

1
Build the programme
Create the programme in a drag-and-drop Gantt with activities, durations and dependencies. Import an MS Project (XML/MPP), Primavera (P6/XER) or Asta (PP) file to pull its key dates and scope anchors across for reference.
The project programmes dashboard — five sample master programmes across UK civils jobs (a motorway junction upgrade, an inner-ring-road scheme, a smart-motorway drainage package, a rail level-crossing renewal and a relief-road project), each showing total and critical activities, percent complete and start-to-finish dates.
2
Work the Gantt and critical path
See which activities drive the completion date so the team focuses on what actually moves the end date, with dependencies and float laid out across the timeline.

3
Baseline and track progress
Take a baseline at contract award, then update percent-complete as work proceeds to see slippage against plan early.
4
Issue a lookahead
Generate a two-, four- or six-week rolling lookahead from the master programme so site teams know exactly what is coming.
5
Evidence delay
Keep a clean record of baseline, progress and delay events to support extension-of-time and loss-and-expense claims.

Features That Move The Needle

Built for high-stakes construction workflows: deadlines, compliance, and audit trails.

Drag-and-drop Gantt

Build and adjust the programme quickly without specialist planning software.

Dependencies and critical path

Know which activities move the completion date and which have float.

Baseline comparison

See slippage against the agreed plan at a glance, not months later.

Lookahead planning

Turn the master programme into a clear short-term plan for the site.

Progress tracking

Update percent-complete and keep the whole team on the same version.

Why It Works

Every project runs from one live programme — a drag-and-drop Gantt with dependencies and critical path — baselined at award and updated as work proceeds. Slippage shows against the baseline early, a lookahead drops out for the site team, and delay events are recorded to support extension-of-time and loss-and-expense claims.

Frequently Asked Questions

Common questions teams ask before they book a demo.

Construction programme software lets you plan a project as a sequence of activities with durations and dependencies, shown as a Gantt chart. It tracks progress against a baseline so you can see whether the job is on time and evidence any delay.

Yes. Dependencies between activities drive a critical path, so you can see which activities determine the completion date and which have float to absorb slippage.

Yes. Take a baseline at contract award and update percent-complete as work proceeds. The programme shows actual progress against the baseline so slippage is visible early rather than at handover.

Yes. Generate a two-, four- or six-week rolling lookahead directly from the master programme so site teams have a clear short-term plan that stays consistent with the contract programme.

Yes. Import an MS Project (XML/MPP), Primavera P6 (XER) or Asta Powerproject (PP) file. Site Samurai parses the activities and pulls the key dates and scope anchors across for reference alongside your live programme (the imported activities are held as a reference copy, not merged into your editable programme).

A baselined programme with tracked progress and recorded delay events gives you the contemporaneous record needed to support extension-of-time and loss-and-expense claims under NEC and JCT contracts.
