Fire Safety
in
Construction
2 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Some of the Problems?
Triangle of fire !
Selection of combustible
or flammable materials
Selection of heat/ignition
producing processes
A lack of planning & management
People cant evacuate – In time !
Ineffective planning of routes
Inadequate prevention of spread
Concentration on completion standards.
3 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Biggest Issue!!
Principal Designers –
no/little fire SKET
Designers – focus on
user, not construction phase
Fire Engineers – engineered
building, no concept/interest of
construction phase fire safety
Principal Contractors – pick up
the pieces & costs!
4 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Recent Experience
Involved with 20 + projects last 2
years
6 projects - High Rise buildings
Fire Engineers & Designers
considered construction phase fire
safety, MOE on ZERO occasions
No consideration of worker safety
No consideration of Fire-fighter safety

Getting it Right – from the
start!
Planning (appendix 3 HSG168)
“A detailed fire risk assessment and required controls need to be developed from the outset,
identifying the stages and activities which give rise to critical risk points
and which, therefore, will need highest levels of control.”
7 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Critical Risk Points
Designer, Principal Designer &
Principal Contractor responsibility
In practice, this means;
Avoiding foreseeable risks
Pre-planning for residual risks
Informing all of the risks
& relevant controls
Introducing controls
at identified CRP’s.

Dead End !
11 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Duty Holders
Designer – Reg 9 CDM
Ensure client is aware of their duties
Design analysis – foreseeable risks
construction, use & maintenance……
Take steps to reduce/control risks
Provide information on residual risks
Co-ordinate their work.
12 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Fire Engineering Design
Only look at final compliance!
No thought of fire strategy for
construction phase.
No controls when
Sprinklers designed in
Dry/Wet risers not commissioned
Engineered to single stair core
Smoke controls designed in…….
Not their problem – down to PC !!
WRONG !!
13 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
14 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Designing with fire safety in
mind!
Practicalities;
When deciding on Build type
When specifying materials
When indicating/recommending etc.
sequence of build
Hazardous process eg hot works
Off site pre-construction
Fire Engineered solutions
Site/building access.
15 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Example
To maximise available ‘usable space’
for a client a designer designs in a
sprinkler system & designs in a
single staircase
Sprinkler system commissioned in last
few days of construction
Travel distances during
construction exceed
Table 1 HSG 168
16 FRM in Con/Tall Buildings Network seminr/apf/19.04.17 rev1
Travel distances
Fire Hazard
Lower Normal Higher
Enclosed structures
Alternative 60m 45m 25m
Dead-end 18m 18m 12m
Semi-open structures:
Alternative 200m 100m 60m
Dead-end 25m 18m 12m

Example - solution
A 14 story building is provided with
2 alternative exits at floors Gr’d – 7th
No scaffold used – mast climbers
for external finish of envelope
Protected staircore from outset
Fire fighting shaft from out set
Dry riser commissioned & available at
3 floor intervals
Dry riser inlet piped to site hording for
fire service connection.

High rise = Higher risk
Considerations
All designers consider Con Phase
CRP’s in programme
Reduce – flammables/combustibles
Fire engineering

Water supplies..
MOE Protected
Existing protection
Needs to be maintained!
