Midland Steel can prefabricate
Diaphragm wall cages
Columns and Beams.
Slab panels & Pile caps
Walls & Stair cores
Certified to CARES Appendix 6 and Appendix 10 for the in-house welding of reinforcing bars.
Full prefabrication service including 3D detailing, reinforcement optimisation and BIM Level 2 project integration available for projects of any size.
Each project is examined individually (site constraints, lifting capacities & site storage) and a prefab plan is developed with the client to ensure all elements delivered can be installed quickly and simply.
Midland Steel’s technical department design/model each project on an individual basis to engineer the most efficient solution for each specific project.
What we require: IFC File of the associated project
From the development of a 3D model to a fully BIM Level 2 model, Midland Steel can bring a complete off-site prefabricated solution to any construction project.
Interactive model which can act as an information transfer between the client and Midland Steel.
All prefabricated elements are assembled in our controlled facilities by our production teams.
Following the model, accuracy and quality is constantly monitored during the assembly phase.
All prefabricated elements are supplied with a Temporary Works design and a Just-in-time (JIT) delivery.
A Lifting beam can be provided with delivery to ensure a smooth and controlled installation. All elements arrive on-site pre-slung ready to be lifted into place.
Elements are loaded and delivered in the most efficient manner depending on the installation sequence and site condition which is fully managed by our contracts manager and the client prior to delivery.
An installation sequence video can be supplied if required to clearly outline each elements sequence and position.
Our installation process is designed to be as simple and efficient as possible.
Depending on the project type all elements join together following the key plan.
Constant interaction between the client and Midland Steel ensure quality from the design through to the installation phase.
CARES Approved Welding
When steel bars are welded together the metalurgy of the bars is affected. Ensuring that the structural, reinforcing steel bars are still able to deliver their full 500N/mm2 yield strength after being welded is of vital importance.
In order to ensure that this is the case, Midland Steel only use CARES certified welders and carry out welding only inside their approved facilities. For this reason, you can be assured that the prefabrication of the cages will not harm the performance of the steel.
“Midland Steel bring a whole new level of professionalism to the steel fabrication industry, something I have not seen from other suppliers. They are a forward thinking, progressive company who are a great ambassador for BIM.
Midland’s detailers worked closely with the structural engineer communicating through the BIM model. Midland’s knowledge & expertise enabled them to change the rebar design of very complex elements to make them lighter (i.e less rebar meaning less cost for the client) and a lot more buildable – all approved by the structural engineer.
The financial saving due to the reduced labour numbers on site as well as the prelim saving in the office was a great bonus. The ease at which we were able to call off the rebar through the model meant that we didn’t need to employ an individual to manage the ordering of reinforcement for such a large project. With just a few clicks, the next rebar delivery was scheduled! The fact that I could take one quick look at the model to find out the status of every element on the job was very impressive.
Having experienced what Midland Steel can offer us through the use of BIM, we are now telling our perspective clients about this element of our overall product which we deliver. It is yielding very positive results due to the enhanced quality, programme certainty, and commercial savings that prefabricated reinforcement offers clients when it is carried out using BIM.”
“Midland Steel were able to offer practical advice on how to detail, fabricate, and install the complex geometric shapes of the columns and crossheads at London Bridge Station.
Approaching each challenge with a collaborative “can do” approach, Midland Steel worked to develop a system that would meet both the technical and programme requirements with financial benefit to the client.”
Health & Safety
Supplying prefabricated cages to site rather than loose bars has many health and safety benefits. Firstly, and primarily, as the cages are lifted in to position by crane, there is no heavy-lifting required by the fixers. Also, by removing the need to tie bars together, the site is not littered with stray bars and pieces of tying wire with the added benefit of needing fewer fixers making fewer movements around site.
Through early involvement in a project, Midland Steel can help to re-engineer a reinforcing solution that can save time and money on site. With advanced detailing consideration, prefabricated cages can be optimised to increase the speed of construction on site. This is a very different mentality to simply prefabricating a loose bar arrangement, this is true value-added performance.
Reduced Skilled Labour
Using prefabricated cages can dramatically reduce the complexity of placing reinforcement on-site. Rather than requiring skilled fixers to select the correct bar bundles and follow a set of detailed drawings, cages can be placed by simply following a numbering system on colour-coded layouts. Most prefab projects can be handled by one skilled fixing foreman with unskilled labourers.
As Midland Steel use industry-leading process management software, programming the production of cages and deliveries to match site programming is second nature. With the added benefit of running their own in-house fleet of vehicles, they are able to offer Just In Time (JIT) deliveries to any UK site with confidence.
When using prefabricated cages, most of the complexity can be taken out of the project during the re-detailing and cage manufacturing process. This means that any errors in the drawings, omissions of bars or issues such as over-crowding can be resolved prior to the reinforcing steel arriving on site.
Simplified Checking Process
It is usually much easier to check the key dimensions of a prefabricated cage prior to lifting it in to position than it is to check the position and diameter of loose bars once they have been fixed in place. This can much increase site accuracy and the speed and ease of the checking process.
