		+
		+	This depends on the shaft type - is this concrete or steel / boarded?
		+
		+	First point is to determine the lift car size - how much clearance is there between the lift car and the shaft walls?
		+
		+	In the event this is a concrete shaft then this can become a significant issue as there is typically no secondary steelwork (to which the combination brackets / guides are fixed) so the ability to adjust these brackets is limited as they are fixed directly to the concrete. This will depend on the amount of clearance between the shaft walls and the lift car - is there sufficient space to install a compliant redesigned bracket?
		+
		+	For steel / boarded type shafts typically there is a secondary steelwork detail that is fixed to the steels within the shaft bridging the gap to the lift car/counterweight guide brackets. In this instance then a consultation with the secondary steelwork designer / installer to adjust the design to maintain the same lift car size could usually be quite easy to do (cost / programme impact aside)
		+
		+	In the worse case then the lift car size will need to adjusted to suit the reduced shaft size.
		+
		+	In my experience the lift supplier will not take 'handover' of the shaft if it doesn't meet the required dimensions.

What if the onsite shaft dimensions as not as proposed by the architect in consultation with the lift supplier. For e.g. Proposed Dimensions are 1950mm*2400mm and onsite dimensions are 1950mm*2288mm. What can be done in that case??
