About us
The Company - the UK's clear leader
Caledonian specialises in the design, manufacture and construction of permanent, multi-storey buildings using off-site modular construction (generally termed “Modern Methods of Construction”). The company operates as both Principle Contractor and Modular Sub-Contractor, constructing projects with values between £1M and £50M. Caledonian is the largest off-site constructor of permanent buildings in the UK, with a turnover in excess of £130M.
Operating from a 42 acre site near Newark in Nottinghamshire the Caledonian facility comprises 4 separate factories, each producing modular units, enabling 4 independent projects to be processed at any one time. Each factory is approximately 120,000 sqft in size and each is capable of producing over 200m2 of accommodation building per day.
The Concept - a visionary approach
Through early involvement in the architectural design process Caledonian’s experienced design teams can ensure that the opportunities for pre-engineering are maximized. By evaluating each structure individually, the optimum construction process can be achieved, ensuring that those elements of the building which suit fully volumetric construction are designed to achieve maximum off-site build content. Certain areas of a building may suit alternative construction methods (for example large Hotel reception areas, galleried atria or sports halls): Caledonian’s design teams are able to integrate other construction forms with modular, volumetric and pod construction to achieve the overall optimum solution for construction.
By establishing long term arrangements with Key Clients, Caledonian is able to function as a key part of the Client’s Design Team from the outset of a project. This ensures that maximum value can be achieved, as the construction process is integrated into the building design from design concept, designing out risk and minimizing cost.
The Benefits – revolutionising construction
The benefits achievable by utilising off-site construction are well documented and impressive:-
Construction Speed – half of the construction site time of traditional construction methods
Minimised Site Disruption – typically 75% of a project’s value is constructed off site, reducing transport, labour and site prelims to as little as 25% of that required for traditional construction
Traditional Equivalence – Caledonian buildings look, feel and achieve the architectural features of traditionally built in situ structures
Height – Caledonian has constructed buildings from 1 up to 18 storeys, in self supporting modular structures; the system capability is greater than 20 storeys
Sustainability Performance – highest standards in environmental performance, both in construction and operation
Quality – proven quality benefits over traditional building
Capacity – the largest off-site contractor in the UK
It is in the careful implementation of the whole design and construction process that these benefits are realized. Caledonian’s established design, commercial, manufacturing and construction teams are experienced in delivering this process for a wide range of building types, examples of which are featured in this website.
