Concrete Frames
Frames That Anchor Ambitious Builds
At J P Dunn Construction, we specialise in the delivery of high-quality reinforced concrete frames. With decades of experience across a broad range of sectors and structural types, we are trusted by main contractors and developers to deliver frames that are robust, efficient, and buildable.
We deliver concrete structures that form the backbone of complex projects—from residential towers to mixed-use and institutional buildings. Our ability to integrate the concrete frame within the wider delivery package (including substructure and external works) ensures programme efficiency, cost certainty, and streamlined project coordination.
Core Construction Techniques
We adopt the most appropriate core construction method to suit the specific demands of each project:
- Traditional shuttered construction
- Hybrid Twinwall systems
- Jump form or slipform for rapid vertical progression
Our in-house planning and preconstruction teams work closely with clients to advise on the most efficient solutions from the earliest stages, often identifying programme and cost savings via smart core sequencing or access strategy.
Post-Tensioned Concrete
For projects where structural efficiency is critical, we offer post-tensioned slab solutions through our specialist partners. This enables:
- Thinner slabs and reduced building height
- Lower concrete and rebar quantities
- Faster cycle times and reduced formwork
- Reduced embodied carbon
All post-tensioned designs are fully coordinated with permanent works engineers and Building Control where applicable.
Formwork & Equipment
J P Dunn has invested significantly in modern formwork systems, access equipment, and our own fleet of concrete pumps. This enables:
- Faster cycle times
- Improved safety through engineered systems
- Reduced reliance on third parties
- Greater quality control and consistency
Our operatives are trained in the use of specialist systems including Peri, Doka, and Ischebeck Titan to deliver formwork that is safe, adaptable, and finish-ready.
High Quality Finishes
Where exposed concrete is part of the final aesthetic, we work with clients to achieve bespoke architectural finishes. We will produce benchmark panels during pre-construction to establish finish requirements, and follow a defined QA regime throughout the pour sequence.
Our teams have delivered high-quality Class A finishes on projects such as Exeter College.
Integrated Delivery
We are able to seamlessly integrate the frame delivery with other packages such as:
- Basement construction
- Groundworks and foundations
- External works and landscaping
This reduces the number of interfaces, improves coordination, and offers greater programme resilience.
