Lift Modernisation in Occupied Buildings – Lift Reliability and Lift Maintenance

Lift Modernisation in Occupied Buildings – Loss of Lift Service, Lift Reliability and Pro-active Lift Maintenance

Lift modernisations in existing, occupied buildings, whether on a single lift or on a group of lifts, will impact detrimentally on the overall lifts service in the building. If the lifts are already heavily used this reduction in lift service can be severe with the potential for loss of business reputation – if clients visit the building regularly, as well as unhappy staff losing working time, whilst waiting too long for lifts.

Health and Safety should always be a paramount consideration with major works going on and large pieces of equipment needing to be removed and replaced.

If the lifts supplies and/or the lift isolators are also being replaced this can require power down periods in the building.

The lifts may integrate with building services, such as fire alarms and building management systems which will need to be tested.

Thorough planning, detailed programming and good communication at all levels are absolutely essential to minimise the disruption caused by major lift modernisation or lift refurbishment work.


Loss of lift Service

The main loss of lift service is due to one or more lifts being out of action whilst being modernised. For small two and three car groups of lifts this can be drastic and unfortunately there is little that can be done about this.

However, it is possible to understand the impact before it happens by carrying out a lift traffic analysis. A lift traffic analysis can accurately estimate what the waiting times and capacity of the lifts will be with a reduced number of lifts.


Lift Reliability

Consider the example of a triplex, three-car group of lifts and modernising one lift at a time. When the first lift is take out for modernisation, the remaining two old, un-modernised lifts will bear the full brunt of the traffic that previously three had coped with!

A consequence of this increased load is that they are likely to become more unreliable.


Proactive Maintenance

The remedy is to work closely with the lift maintenance company to ensure they are more proactive with the maintenance. Before the modernisation starts the lift maintenance company should spend time on the old lifts thoroughly cleaning and adjusting them. Doors should be a particular focus because the doors usually account for around half of all breakdowns on lifts.

The frequency of maintenance can also be increased from monthly to perhaps bi-weekly or even weekly. If this is agreed up front during the negotiation before an order is placed, then often a lift company will include this at no or little cost.

A plus side is that once the first lift is being modernised there is cache of spare parts available. However the ‘service’ and ‘modernisation’ side of many lift companies in our experience could often communicate better and the lift company may need to be directed to retain certain components from the old lift being modernised rather than dispose of them directly.
