Laminated Veneer

Lumber (LVL) is a

high-strength

engineered wood

product. Thin veneers

are oriented in the

same direction and

glued together

Glulam, short for glued

laminated timber, is an

engineered wood

product manufactured

by gluing together

pieces of timber,

known as laminates.

Cross Laminated Timber

(CLT) is an engineered

wood product used for

pre-fabricated structural

applications. Layers of

timber, known as

lamellas, are glued

together with the grain

alternating at 90 degree

angles for each layer

housekeeping - less dust, less

vibration, noise impact

• Reduced impact on local

communities – no complaints from

neighbours regarding noise

• Reduction or elimination of hot

works

• Light weight battery powered tools

• Handrails pre-installed to perimeter

floor panels prior to lifting into

position

• Safety nets installed between beams

The biophilia hypothesis

suggests that humans possess

an innate tendency to seek

connections with nature and

other forms of life.

“The application

of wood visual

surfaces indoors is

one way to reduce

stress and promote

health in building

occupants.”Wood and Human Health, University

of British Columbia

• Every project is different

• Early engagement with all

stakeholders and focus on co-

ordinated BIM

• Design freeze early

• Degree of prefabrication

• Reduction in labour and change to

type of work

• Increased reliance on planning &

logistics

• Faster delivery with prefabrication

• Follow on trades can start

immediately, no props or curing time

• BIM coordinated, no change to

structure onsite

• Early Contractor Involvement is key

• Open Plan Office – with

exposed timber soffits – no

ceilings

• Typically galvanized finish

to all exposed services

EFFECTIVE

Electrolysed water is up to 80 times more

effective at killing pathogens than common

bleach

ECONOMICAL

Costs 95% less than traditional hygiene

chemicals to produce on-site. An eWater

System will typically pay for itself within 2-3

years.

SAFE

eWater is non-toxic, non-hazardous and

hypoallergenic. It does not require personal

protection equipment when in use or first aid

if you come into contact with it.

SUSTAINABLE

Using an eWater System will reduce your

chemical and carbon footprints, as well as

reducing chemical contamination and

pollution.

FAST

eWater System’s on-site production provides a

ready-to-use, supply of cleaning and sanitising

solutions.

SMART

eWater significantly reduces packaged

chemical waste which benefits the

environment and your health.

eWater is electrolysed salt water, produced by applying a small amount of energy to a mixture of salt and water. Positive and

negative charge points in the electrolysis system create two highly effective yet remarkably safe solutions - an alkaline

cleaning agent and an acidic sanitiser.

eWater was recently accepted by the IBWI as an AAP within the WELL standard, in particular with regard the Cleaning Protocol.

• People-centred design at an architectural scale.

• Australia’s tallest and largest engineered timber office building by GFA, and next

generation of sustainable workplaces.

• As durable as traditional construction forms with enhanced design life and performance.

• Highly sustainable development model – low carbon, low waste, reducing water use and

highly energy efficient.

• Setting global benchmarks for sustainability, connectivity and lifestyle.
