Shared Boosted Riser in Lewisham

The Brief

Risk Category: Cat 2, 2 head risk, 30 minutes run time
Number of heads: 606
System Type: Shared Boosted Riser

This fire sprinkler installation in Lewisham related to 2 blocks of flats and maisonettes.

The system was designed for full coverage of heads, 606 in total, to the maisonettes and flats within both blocks. The design incorporates a valve per floor per riser arrangement off the shared boosted riser.

The work took several visits to site to install 1^st and 2^nd fix of the systems working around other contractors at various stages of the project. 5 months after starting the project the blocks were ready for completion, sounders alarms, cover plates were all installed, and the system commissioned.
