Takt & CPM Contract Language
1. Purpose and Scheduling Philosophy
This Specification governs how the Project shall be planned, scheduled, controlled, reported, and recovered. It applies to all Work performed under the Agreement, including engineering, procurement, construction, pre-commissioning, commissioning, testing, startup, and closeout.
The scheduling system is a paired system. Takt Planning is the production system. The Critical Path Method (CPM) is the contractual as-built record. The two systems are designed to complement one another, not compete.
Two Plan Levels — One System
- Takt is the driver. The Project shall be planned, executed, controlled, and recovered from the Takt plan. Takt is the philosophy, the production engine, and the day-to-day plan that the field works from.
- CPM is the record. The CPM Schedule shall be retained as a high-level summary of phases and non-repetitive sequences for contractual, reporting, forecasting, and Owner-coordination purposes. It serves as the as-built schedule of record. The legitimate uses of the CPM Schedule with the Owner are listed in Section 6.2; it shall not be used to drive field production, dictate sequence, allocate crews, or override Takt control.
