Berkeley Homes, Oxford
Project: Berkeley Homes – Lucy’s Eagle Works, Oxford
Scope: 30 Luxury houses
These three and four storey luxury houses required in excess of 10,000m of BCI® Joists. Sixteen of the houses had three BCI® Joist floors in them designed to a maximum deflection of 6mm.
The BCI® Joists also had large bespoke holes pre-drilled in the webs to allow easy installation and access of services.
Boise is offering the pre-cut holes as an alternative to the standard pre-stamped 38mm diameter knockout holes at 302mm centres. Typical sizes are 125mm circles and 125mm x 300mm rectangles, which can be aligned across the floor, ideal in situations where copper piping, soil vent pipes or ventilation ducting are required.

Westbury Homes, Tiverton
Project: Westbury Homes – Phase 2, Cowley Moor, Tiverton
Scope: 70 Houses
Two and three storey houses all utilising 302mm deep BCI® Joists and VERSA-LAM® Beams.
The use of BCI® Joists as rafters supported at wallplate and by a VERSA-LAM® beam at the ridge achieved significant savings in cost and time over the original steel beam, stub truss and loose rafter infill arrangement. The depth of rafter provided by the BCI® Joist permitted a simple approach to meeting the insulation requirements.

Westframe Timber Frame
Project: Westframe (Westleigh developments Ltd) – Countess Rd , Northampton
Scope: 83 units for Nottingham Community Housing Association
These three storey units have been designed using 302mm deep BCI® Joists and VERSA-LAM® Rim Beam.
VERSA-LAM® as rimboard is coated in a water-repellant sealant with a UV inhibitor for improved protection during construction and is an ideal product for timber frame applications.
Westframe use the VERSA-LAM® as rimboard to transmit the vertical loads from load-bearing walls through the floor construction to the load-bearing walls below.
The VERSA-LAM® beams can also be used in six storey projects as a ringbeam where disproportionate collapse loads need to be taken into account.

Bellway Homes, Tiverton
Project: Bellway Homes – Abbey Manor, Yeovil
Scope: 168 Units
Bellway Homes generally use the Simple Framing System™ throughout their sites in the South and the South West.
All BCI® Joists are generally 302mm deep. Most floors and use the Boise I-bloc™, which ensures quick, simple and robust floor construction.
The Robust Details Handbook for Part E (sound) now gives permission to build joists into walls using proprietary joist caps. The I-bloc™ is a simple joist cap solution and has been designed to push-fit onto the BCI® Joists.
With the I-bloc™ - which enjoys acceptance from NHBC – joists can be built straight into external and party walls, giving the builder greater tolerance for block work whilst saving the awkward fitting of parallel restraint straps and mastic sealant.

Persimmon Homes, Lee-on-Solent
Project: Persimmon Homes – Cherque Farm, Lee-on-Solent, Hampshire
Scope: Several Phases of Houses & Apartments
Boise have been supplying BCI® Joist floors to several phases of ‘Cherque Farm’ over the last three years.
This site has experienced a wave of innovation from start to present as far as I-Joist floors go.
The older style connections inherited from the US have gradually evolved into more robust and easy to install connections on site. No more ply backer blocks, no more sawn filler blocks, no more cutting holes for straps and no more need for masonry hangers and propping.
Site now use backer-block less hangers, 2-ply BCI® Joist Girder Clips, Cullen PFS restraint straps and the Boise I-bloc™.
