The UK regimes that decide what a project owes, and when. Written for the person who has to act on them this week.
When is a project notifiable under CDM 2015?
The 30-working-day-and-20-worker test, the 500 person-day test, who owes the F10, and why the answer changes when the programme does. Includes the two duties people routinely confuse with notifiability.
Temporary works: the register, the check category and the permit to load
What BS 5975 procedural control asks for: the roles, what design check categories 0 to 3 actually mean, what a register should hold, and why a permit to load should follow an inspection rather than a date.
RIDDOR 2013: what is reportable, and the clock that starts on the day
Deaths, specified injuries, dangerous occurrences and the over-seven-day rule, with the deadlines that run from the accident — and the difference between reporting and recording.
Payment notices under the Construction Act: the deadline that decides who keeps the money
The due date and the final date for payment, the payment notice and the pay less notice, what the notified sum is, and what happens when neither notice is served — including where the payer stands afterwards.
Section 74 overrun charges: the cost that accrues per day while nobody is looking
Permits and durations, how the daily overrun charge is set by road category and traffic sensitivity, fixed penalty notices, and the three reinstatement clocks that run independently of each other.
Waste duty of care: the load that is still yours after it leaves site
The section 34 duty, transfer notes and hazardous consignment notes, List of Waste codes and mirror entries, checking a carrier's registration on the day of the transfer, and the two-year and three-year retention periods.
Extension of time: the notice that has to go in before anybody knows the answer
When notice is owed under JCT and NEC, whether it is a condition precedent, why time and money are separate questions, concurrent delay, who owns float, and what every method of delay analysis needs from the records.
