According to the Construction Product Association (CPA) latest forecasts, the construction industry will grow by 10.0% over the next two years.

Private housing starts are expected to grow by 18.0% this year and 10.0% in 2015, while commercial office construction output should grow by 10.0% this year and 8.0% in 2015;

CPA economics director Dr Noble Francis said:

“The forecasts reflect the increasing strength of the sector, though risks remain. We anticipate the recovery will continue through the forecast horizon in 2018 and broaden both across sectors and regions. Overall levels of activity will likely match their 2007 peak in 2017.”

He continued:

“In the short-term, the activity will primarily be led by private housing, infrastructure and commercial. Notably, in the long-term, we expect this activity will be boosted by work on schools and hospitals.

“The private housing sector continues to benefit from the improving economic backdrop and government policy measures, with housing starts expected to grow 18.0% in 2014 and 10.0% in 2015. The pending general election, however, will cast the future of housing policies into doubt. Such uncertainty, together with questions about affordability and higher mortgage repayment costs, will likely subdue private housing growth to 5.0% per year from 2016.”

Visqueen Gas Protection Systems supplied for prestigious Library of Birmingham project

Client:             Carillion
Location:       Library of Birmingham
Date:               June 2013
Sector:            Education

About the project:

One of the most prestigious projects that Visqueen Building Products supplied products to in 2013 was the Library of Birmingham in the city’s Centenary Square.

The library is situated in one of the city’s most important public open spaces in the heart of Birmingham city centre’s Westside.

The new library features many innovative design and construction techniques. It has two elevated outdoor garden terraces which offer an environment for visitors to unwind, socialize and learn, as well as bringing environmental benefits through offsetting carbon emissions and attracting wildlife and local ecology.

Key facts

  • Opened in September 2013
  • Overall building cost – £188.8 million
  • Main contractor – Carillion
  • Designer – internationally acclaimed Dutch architects, Mecanoo
  • Expected to attract around 3.5 million visitors annually

Project challenges:

The build site was contaminated with CO2 gas, which posed a key challenge for Carillion as a specialist gas protection system would be required to make the development safe for construction. As a leading technical authority in the provision of gas protection systems, Visqueen was called in to provide knowledge and expertise in specifying the correct gas and damp protection solutions for the site conditions.

Visqueen worked closely with site managers and personnel, providing consultative support throughout the project. This involved advising on the correct products and system accessories, supplying accurate CAD details and overseeing installation.

Chris Hayes, Technical Support Manager at Visqueen who worked with Carillion on site explains further:

“We supported the team from start to finish, ensuring that all gas and waterproofing products were installed in accordance with the latest building regulations, and we were able to provide technical sign off of the finished installation.”

Michael Heir, Masonry Advisor at Carillion Technical Services commented:

“The decision to use Visqueen Zedex High Bond DPC to waterproof the base of the cavity at Birmingham Library proved correct. Visqueen technical support at Birmingham Library was excellent.”

Solutions:

Gas Venting Systems

There were a number of Visqueen products used throughout the construction of the new library. Products that were supplied by Visqueen Building Products were:
