New metal web joist guidance published for housebuilders

Uncategorized

A new technical guide on metal web joists is being issued to housebuilders in the UK to showcase the flexibility and benefits of the product.

Metal web joists are made from strength graded softwood chords joined with high strength engineered steel webs. They are structural components which can create floors, roofs and walls. Their open structure makes them lighter to handle and allows for services to pass through easily. Joists can be assembled onsite or a fully assembled floor or roof cassette can be manufactured offsite, helping to support the industry’s move towards modern methods of construction (MMC).

Published by the Trussed Rafter Association (TRA), the Metal Web Joist Buyers’ Guide provides information, illustrations, guidance and handy checklists covering all aspects of floor design and loading, and fixings between the joists and beams within the floor zone.

Nick Boulton, TRA chief executive, said:

“We have developed the Metal Web Joist Buyers’ Guide to help housebuilders and designers understand all the benefits and flexibility of this product. With increasing interest in MMC, metal web joists are ideal components to help speed up and improve the build process. Floor and roof cassettes also decrease the amount of time spent working at height therefore improving safety.

“The guide offers information on design responsibilities, structural considerations, and the metal work required. There is also information for contractors to explain how to store and install once onsite and of course advice on staying safe when working with metal web joists.”

Collaboration is key in successful early completion of M23 project

-laying a record breaking 52,000 tonnes on a smart motorway in one month-

Through a number of evening and weekend closures and successful collaborative arrangements, leading construction and infrastructure player, Aggregate Industries completed the surfacing works ahead of schedule on the M23 smart motorway project, laying 52,000 tonnes of asphalt in one month.

The project is a great example of collaboration, engaging with external stakeholders across the supply chain to ensure the tight deadlines were met, resulting in breaking industry records to not only complete on time but ahead of schedule.

The works included widening of the carriageway to achieve the all lane running requirement, full depth reconstruction of the hard shoulder, central reserve works and collaborative completion of junctions 9,10 and lane four surfacing to enable the road to open for traffic.

With Aggregate Industries’ Contracting Division acting as the lead surfacing partner, the materials for the project were supplied by its Asphalt and Aggregates Divisions, and delivered by its Logistics Team..

The company also took responsibility for recycling 100% of the old waste material from the pre-existing road utilising a local recycling facility that crushed and screened it for use in the new asphalt. A proportion of the material will also be used, where possible, in Aggregate Industries’ larger asphalt plants within its materials. As a result of the close proximity of the recycling facility, less haulage was required reducing the project’s carbon emissions.

Faced with an immense tonnage of asphalt to lay in an extremely tight deadline, Tarmac were enlisted to act as a second surfacing partner, drawing upon a long standing relationship with Aggregate Industries through the Highways England Category Management Pavement Framework. The collaboration between all parties; similarities in systems of working; and the ability to share resources, drove efficiencies that resulted in achieving 52,000 tonnes laid in one month, completing the pavement works by the end of March, 6 months ahead of the initial forecasted completion date.

In addition to the logistical, technical and time requirements for the project, the team also had to quickly adapt to a new working environment due to the Covid-19 pandemic. Undeterred, the team planned out stringent working arrangements with all parties involved to make sure that the project was finished in accordance with social distancing guidelines.

Paddy Murphy, Managing Director of Contracting at Aggregate Industries, said: “Not only is this project a great example of collaboration, flexibility and ingenuity within Aggregate Industries, but it is also further testament that even in uncertain times, businesses like ours, and all the parties we worked in close partnership with, are essential to keeping the country moving.”

The success of the project has garnered significant praise from Highways England and principal contractor Kier, the CEO of which said: “I wanted to take this opportunity to thank the team for your role in securing the extraordinary achievement of the March Open For Traffic target on our M23 Smart Motorway Project. When the challenge to accelerate this project was set back in October, the collaboration, enthusiasm and commitment shown across the entire project team, including our supply chain partners, has been magnificent.”
