Get in touch with us directly through our contacts page. If you send us project drawings our team of engineers will generate a preliminary design using APTUS elements that will comply with the project engineer’s requirements and satisfy temporary works. We can then arrange a budget price though one of our partner precast manufacturers for supply and delivery of the precast elements.

APTUS columns and wall elements are designed to cantilever off the element below in the temporary case and do not require any propping. Once the couplers are locked down, the crane can be unhooked and the APTUS element will stand self supporting on the couplers.

APTUS columns and walls do not require any grouting. There is no requirement for additional work after installation. The APTUS elements are installed prior to the slab pour, then the slab is poured through under the columns, job done.

APTUS elements need to be installed by an APTUS approved installation partner. There are a few options available to builders.

1. APTUS can provide pricing for installation by our experienced in-house crew teaming up with your crane crew. The benefit of having the APTUS supervisor on site is you will have someone to manage and coordinate deliveries, efficient use of crane and manage all installation QA requirements and documentation.
2. Engage a third party APTUS approved installation partner.
3. Engage an APTUS approved pre-caster as a part of a supply and install agreement.
4. If you would prefer to have members of your site crew trained and approved to install APTUS elements, please complete the form and register your interest in becoming an installation partner.

In most projects, the permanent case design remains the responsibility of the project structural engineer. APTUS can arrange temporary works certification for the pre-caster/builder. This means it is important that APTUS’ engineers liaise with the project engineers throughout the design process to ensure the design will meet both the in service and temporary case requirements.

In some instances, it is preferable that APTUS arranges engineering certification for the in-service design, offering the builder a Design and Construct option for the precast vertical elements based on ultimate loads and moments provided by the project engineer. Our preference and best practise is for the permanent case design responsibility to remain with the project structural engineer.

APTUS components are manufactured and tested in accordance with ISO 15835-1:2018. APTUS has CARES certification for the couplers to be used in the United Kingdom and we are currently working on certification for other jurisdictions. To obtain CARES certification, APTUS has passed stringent testing of the components and audits of our quality systems and the quality systems of the entire supply chain.

Option 1: The time poor engineer is more than welcome to send the drawings through to us and we will generate a preliminary design using APTUS for the vertical elements. We can also arrange budget pricing of the precast elements for your builder.

Option 2: The better option is to sign up for the partner program as an engineer. You will get access to our preliminary design software free of charge and access to support, advice and training from our engineering team. We can advise on where APTUS is best suited to be implemented in the design.

Aptus couplers are currently available in sizes to connect reinforcing bar from 20mm up to 40mm diameter. Refer to our APTUS product catalogue for more information. Our catalogue will be updated as our product range expands.

The couplers come in N24, N32 and N40 sizes. For an N20 design we will use N20 bar in the element but use N24 couplers. likewise an N28 design will use N32 Couplers and an N36 design will use N40 Couplers.

The couplers and components are manufactured from 4140 High Tensile Steel.

The APTUS coupler system complies with the requirements of Section 13.2.6 of AS3600:2018 relating to welded or mechanical splices. This section requires that splices formed between reinforcing bars shall not fail before the reinforcing bars (effectively a “bar break” system). We have testing to show the coupler system exceeds bar break capacity. APTUS carries out ongoing testing of the couplers and friction welding process to ensure that the manufacture of the components continues to satisfy the requirements of AS3600:2018.

The couplers also comply with the slip limits as specified in Clause 13.2.6 of AS3600:2018.

We recommend APTUS elements with a width 250mm or greater are detailed with a tapered base to assist in the expulsion of air and to ensure maximum compaction is achieved. However the biggest impact on adequate compaction is the vibration technique used on site.

The concreters should follow our recommended compaction method which is documented in our standard details. The contractor must supervise the concreters and ensure they are following the method carefully on every column.

Typical lead time on supply of APTUS components to a pre-cast manufacturer is 7 days from order. The best approach is to be in contact with APTUS during the design stage so we are fully aware of your project requirements.

The couplers and components are manufactured from 4140 High Tensile Steel.

There is a solution for every transition type where the footprint of the element over aligns with a sufficient area of the element below. Refer to our typical details on the downloads page for examples on how to handle different transition types.
