Introduction

Issues:

• 15% Roof light requirement

• Confirmation of Smoke Vent size & Position

• Full Sprinkler Installation

• 2.5m3/m2.hr air tightness requirement

• Blockwork to B&Q requirements

Design Coordination

Issues:

• Bottom 2.475m constructed of blockwork

Design Coordination

Issues:

• A completely new technology with no experience

• We didn’t know the who, the how or the specific

requirements for the installation

• Main problem was placing the subcontract order and

timing for the install

• Tata Steel’s Terms and Conditions were ‘difficult’ for

BAM to agree.

• Not just a product specified by an Architect/

Engineer for installation by a BAM Subcontractor

Design Coordination

Design Changes:

Headlines

• Change of roof from Kalzip to Euroclad SF500

• Green Roof required to outer slopes for planning

• Roof light requirement of 15% compromised by Solar

Collector and other design requirements.

• Mansafe requirement for ‘Fall Prevention’ to roof

rather than ‘Fall Arrest’, increased walkway/

latchway requirement.

Commercial Reality

■ Tata asked to provide a Performance Warranty

■ BAM had to take make some very difficult decisions

regarding roofing products

■ Value Engineering assistance provided by Tata was

supportive

■ Numerous hours spent by Tata and BAM discussing the

objectives of the SBED programme

■ Understanding of the what was important of the install of

what appeared to be ‘standard’ building components

Build Reality

■ Standard recognisable building components

■ Understanding of bringing ‘stranger’ trades together

■ Length of panels were difficult to handle

■ Installed following completion of the main roof
