Precast cladding support – how do I ensure my panel fixings don’t go over budget?

The Rise of Using Precast Cladding for MMC

The construction industry has seen a significant shift towards Modern Methods of Construction (MMC), with precast cladding becoming increasingly popular. This method offers numerous benefits, including improved quality control, reduced construction time, and enhanced sustainability. However, managing the costs associated with panel fixings can be challenging. This article will explore how to ensure your panel fixings stay within budget while using precast cladding.

What is Precast Cladding?

Precast cladding involves manufacturing panels offsite in a controlled environment and then transporting them to the construction site for installation. This method provides high precision and consistency, reducing the likelihood of errors and rework. Precast cladding can be used for a variety of applications, including facades, walls, and decorative elements, making it a versatile choice for many projects.

The Different Support Options

Choosing the right support option for your precast cladding is crucial to maintaining budget control. Here are the primary support options:

• Billets: They support the panel from the bottom and are usually suitable for projects where high load-bearing capacity is required. However, they can be more expensive due to the material costs.
• Hangers: They are metal brackets that support the precast panels from above. They are often more economical than billets and can provide sufficient support for lighter panels. Hangers are easier to install and adjust, making them a popular choice for projects with tighter budgets or where flexibility in installation is needed.
• Concrete Corbels: Like billets they support the panels from the bottom and are formed as a part of the main facade panel structure. They are used when the loads are very high and can therefore transfer that load back to the main slab in an efficient manner.

Each option has benefits over the other and depending on the project type is best to select the most appropriate support options to ensure that budgets remain on track. I have highlighted a few comparison areas below that should be considered:

Template on How to Work Out Which Support is Best for Your Project

To determine the best support option for your project, follow this template:

1. Assess Load Requirements: Determine the weight of your precast panels and the load-bearing capacity needed for your support system.
2. Material Costs: Compare the costs of billets and hangers based on the material and quantity required.
3. Installation Complexity: Evaluate the complexity of installing each support option. Consider the time and labor costs associated with installation.
4. Project Timeline: Analyze the impact of each support option on your project timeline. Choose the option that aligns with your schedule and minimizes delays.
5. Flexibility: Consider the flexibility needed for your installation. If adjustments are likely, hangers might be the better option due to their ease of installation and adjustment.
6. Available fixing point in reference to the panel.

By carefully considering these factors, you can select the support option that best fits your project's requirements and budget constraints.

The use of precast cladding in MMC offers numerous benefits, but managing costs, especially for panel fixings, requires careful planning and analysis. By understanding the different support options and applying insights from previous projects, you can ensure your panel fixings remain within budget.
