The second booking is where plans fail
Client agreement is straightforward: a date, a scope, a price. Building agreement is a different process involving a dock booking, a service lift allocation, an after-hours access approval and sometimes product documentation. Each has a lead time and a queue, and any one of them failing means the equipment arrives at a building it cannot enter.
Recording that process during mobilisation is what prevents it. The plan should name the building contact, the notice period, the form or system used and the peak periods when slots are scarce. Those details are tedious to collect once and they remove a recurring failure that otherwise consumes a periodic programme over a year. Recording the peak periods when slots are scarce also allows the periodic calendar to avoid them rather than colliding with them each quarter.
