Which path controls handover?

Aerial teaching scene with water-main works crossing a road and a separate kiosk compound.

1. Project brief

The delivery scheme

The main and kiosk follow different paths to handover. You are testing a delay to see whether it consumes spare time or moves the finish.

Which path controls handover?

Use the programme you saved or the supplied baseline. Predict a duration change, then trace its effect to handover.

Water-main and kiosk project · BL-1

Supplied Scope teaching baseline, version 1. Scenario approval supplied for learning; independent technical review pending. Scope WMK-1. Independent kiosk package completion includes installation, connection, testing and acceptance.

Calendar: Monday to Friday, no holidays. Day 0 is Wed 14 Oct 2026 start; day 8 is Fri 23 Oct close. Durations use whole working days. Only finish-to-start, zero lag and zero-duration milestones are supported.

CA-WM maps all ten bay budgets to activity P. Excavation, final system testing and kiosk costs are outside this control account.

Show a short worked example

A five-day path and a three-day path meet at one milestone. The shorter path can take two extra days without moving that milestone. This spare working time is its total float. At five days both paths drive the milestone.

Terms for this task

Total float is the working time an activity can move before it delays the selected finish milestone in this model. Follow the connected path, not just the longest individual bar.

On site

Two assets, one handover

Water-main works

Trace the handoffs between excavation, installation and testing. A dependency needs a physical, access or contractual basis.

Illustrative scene. Use the lesson figures and records for measurements.

Dates follow the selected logic. Bars are not draggable date constraints. Day 0: Wed 14 Oct start.

Ten bays, one installation crew; includes local bay inspection and rework allowance.

Saved project outputs

Baseline BL-1 remains unchanged. Saved versions below are retained; new work creates another version.

Structured-data CSV for review. It is not a native Primavera or Microsoft Project schedule.

Model limits and reference basis

One working calendar, finish-to-start zero lag. No automatic resource levelling, date constraints, progress override, baseline approval workflow or native scheduling-software export. Saved narrative is authored by you; validation checks evidence, model consistency and required fields, not the professional quality of every explanation.
