Build programmes that survive first contact with site
Methvin gives construction planners an integrated platform for Gantt scheduling, project management, quantity-linked durations and BIM 4D coordination — so your programme is grounded in real data from the first draft to practical completion.
Planning tools that reflect construction reality
Every module is designed around how construction programmes are actually built, maintained and communicated — from preliminary programme to as-built record.
Durations Derived from Real Quantities
Link Gantt task durations directly to takeoff quantities and crew productivity rates. When a scope changes in the estimate, the programme updates automatically — no more manually recalculating pour durations from a separate spreadsheet.
Dependencies That Reflect Site Logic
Model finish-to-start, start-to-start, lag and float with the nuance construction sequences require. Critical path is calculated continuously so you always know which delay is absorbing float and which is genuinely threatening completion.
4D BIM Without the Specialist Overhead
Link Gantt tasks to BIM model elements and visualise the construction sequence in 3D. Identify space conflicts and trade sequencing clashes in the model before they occur on site — without needing a dedicated BIM coordinator.
Programme and Project Management in One Place
Issue RFIs, manage submittals and track programme milestones from the same platform. When a submittal delay affects a task start date, the impact on the programme is visible immediately — not discovered two weeks later in a progress meeting.
The planner's integrated toolkit
Four modules designed to work together — from programme build to 4D model coordination.
Gantt Scheduler
Build and maintain construction programmes with full CPM logic — predecessors, successors, lag, lead and float. Set a baseline, track progress against it and produce formatted look-ahead programmes for weekly site meetings.
Explore Gantt Scheduler →Project Management
Manage the information flow that drives your programme — RFIs, submittals, design deliverables and approval milestones. When an RFI response is overdue, the linked Gantt tasks show the impact on downstream activities immediately.
Explore Project Management →Takeoff
Measure work quantities directly on digital drawings and link them to Gantt task durations via productivity rates. Scope changes in takeoff ripple through to programme durations automatically — your programme stays calibrated to actual scope at all times.
Explore Takeoff →BIM
Link Gantt tasks to IFC model elements to visualise the construction sequence in 4D. Simulate the programme month by month to identify trade and space conflicts, then export clash reports for pre-construction coordination meetings.
Explore BIM →Programmes built on data, not optimism
Most construction programmes are disconnected from the quantities, submittals and model information that should be driving them. Methvin links all four together so your schedule reflects what's actually happening — not what you hoped would happen.
- Task durations calculated from takeoff quantities and crew productivity rates — not guesswork
- CPM critical path recalculated in real time as progress is updated
- 4D BIM simulation runs directly from your Gantt with no file export required
- RFI and submittal delays surface as programme impacts before they cause slippage
- FBaseline comparisons show slippage by phase, trade and responsible party
- Look-ahead programmes and progress reports generated directly from the live schedule
Trusted by construction planners and schedulers
Feedback from planning professionals who've replaced disconnected scheduling tools with Methvin.
“The link between takeoff quantities and Gantt durations changed how I build programmes. For repetitive floor cycles I set the productivity rate once and the programme writes itself. Scope change updates that used to take half a day now take minutes.”
“Running the 4D simulation before tender and finding three trade clashes in the services coordination was the return on investment on its own. The client saw the simulation in the presentation and it won us the job. Nothing else I've used does this without a specialist operator.”
“Having RFI and submittal status visible alongside the Gantt is what I didn't know I needed. I can now walk into a programme review and show exactly which design decisions are on the critical path and who owns them. Conversations with clients are very different now.”
Questions planners ask before switching
Answers to the most common queries from construction schedulers evaluating Methvin.
Can I import an existing programme from MS Project or Primavera?
Yes. Methvin supports import from Microsoft Project (.mpp) and Primavera P6 (.xer) formats. Task structure, dependencies, durations, baselines and resource assignments are preserved on import so you can continue an existing programme without rebuilding it.
How does the quantity-to-duration link work in practice?
When you create a Gantt task you can link it to one or more takeoff measurements and assign a productivity rate (e.g. 120 m² concrete slab per crew day). The task duration is then calculated automatically from quantity ÷ productivity rate. If the takeoff quantity changes, the duration updates immediately.
Does the Gantt support full CPM with float and critical path?
Yes. Methvin calculates early start, early finish, late start, late finish and total float for all tasks. The critical path is highlighted and recalculates continuously as you update progress or adjust dependencies — there is no need to manually trigger a recalculation.
What BIM formats does the 4D simulation support?
The BIM module accepts IFC 2x3 and IFC4 files. Once imported, individual elements or groups are linked to Gantt tasks. The 4D player then animates the construction sequence at any time increment and allows you to step through the programme month by month or week by week.
Can I produce look-ahead programmes and progress reports directly from Methvin?
Yes. Filtered views can be saved and exported as formatted Gantt PDFs for site distribution. A two-week or four-week look-ahead view is configurable from the live programme, meaning your short-interval schedules are always derived from the master programme — not a separate document.
How are programme delays and time extension claims supported?
Baseline comparisons show current versus planned dates at task and phase level with variance in days. The delay event log links RFIs, variations and weather records to affected tasks, providing the structured contemporaneous record needed to support time extension claims under most standard contracts.
