How to sequence equipment on a tight site programme
On a constrained site there is no room to stockpile plant. A guide to sequencing equipment to the programme so machines arrive when needed, work, and leave, without choking the site.

On a spacious site you can stage equipment in advance and have it waiting. On a tight one you cannot. There is no lay down area, no room to park a crane between lifts, and no space to hold a delivery that arrives early. The only way to keep the work moving is to sequence equipment to the programme, so each machine arrives when it is needed, does its job, and leaves to make room for the next.
This turns equipment hire into a logistics problem as much as a supply one. The constraint is not whether the machine is available, it is whether there is room and time for it on the day. Plan that well and a cramped site runs smoothly. Plan it loosely and the site chokes on its own deliveries.
Space is the hidden constraint
On a tight site, the limiting factor is rarely the machine. It is the room and the slot. Sequence to the space you have, not the plant you could order.
A tight site is a timing problem
Every machine on a constrained site competes for the same access, the same crane time and the same standing room. Bring two together that did not need to overlap and one blocks the other. The programme has to choreograph arrivals and departures so the site is never holding plant it cannot use.
Sequence, do not stockpile
The instinct to have everything on site just in case is the enemy of a tight programme. Idle plant takes space, blocks access and still costs money. The discipline is to call equipment to a slot, use it, and release it, keeping only what is working on site at any time.

How to sequence it
- 1
Map the programme
List every lift and plant task against the dates it has to happen.
- 2
Assign slots
Give each machine a window to arrive, work and leave, avoiding overlaps that clash for space.
- 3
Coordinate deliveries
Time material and plant deliveries to the slots so nothing waits on site.
- 4
Hold one point of control
Run it from one team that can flex the sequence when the programme moves.
One late machine stalls the chain
On a sequenced site there is no buffer. A machine that arrives late or overstays its slot pushes everything behind it, so the plan needs a single owner who can re time the chain quickly.
We coordinate equipment and transport to the programme from one control room, so a tight site gets the plant it needs exactly when it needs it. Share the programme and the access and we will sequence the plant to fit.
