Galliard Development in London Docklands


Harbour Central, London UK

Harbour Central is a development in London’s docklands comprising of 642 private apartments divided across seven residential blocks. A leisure complex will include a ‘Resident’s Club’ with a library, concierge, gym, spa, business suites and cinema. The development also includes 238 social rented / shared ownership homes.

Using the traditional methods to firestop pipe penetrations through concrete slab – whether by using wooden boxes or shuttering before or breaking or diamond coring the concrete slabs after the concrete is poured – are time and labour intensive.

The other concerns for traditional methods of fire stopping HDPE soil and waste stacks are:

• Materials are bought and stored for creating formwork. i.e. plywood needs to be bought, stored, cut, fixed and maintained until the mechanical sub-contractor can install the pipework. This is an additional on-site cost

• Openings must be covered during the construction process prior to installing the pipework to avoid health and safety issues with falling objects or trip hazards

• Working at height may be required to create formwork around pipes prior to backfilling.

• When backfilling mortar may need to be mixed on site and this involves a certain amount of manual handling including barrels, buckets etc.

Hilti CFS-CID Firestop cast-in device was the selected solution and significantly reduced the cost and installation time to firestop concrete slabs compared to traditional methods. The cast-in devices also have the added health and safety benefit of no openings left in the slab during the construction process.

The other benefits of the cast-in device were:

• Saves time detailing individual openings and firestopping details

• Can be inputted directly into the 3D model which is accurate enough to produce ‘Construction’ drawings

• Product has all of the necessary certification including BS EN 13501 and BS EN 1366

• No need for backfilling as all results achieved without any type of backfill
