I-W designs detailed engineering solutions to meet the performance criteria of clients or architects. Working with a variety of materials since 1963 has given I-W invaluable experience. This brings clients the benefits of value-engineering solutions and cost-effective designs without prejudicing the appearances of the building.

I-W offers a service where it takes on design responsibility to meet specific requirements. These include satisfying performance criteria relating to structural integrity, fire and acoustic ratings.

The emphasis is on cost-effective solutions that promote fast and safe methods of construction, which accurately interpret the design concept and do not compromise aesthetics. The process places the responsibility and risk on those best able to accommodate it. In particular, it promotes greater interaction between specialist trade contractors in the co-ordination of their respective activities and construction interfaces.
