Heaters & Vessels

During a turnaround it is often essential to inspect and repair heaters and vessels internally. One huge challenge encountered by engineers is the fact that the majority of the limited time available is allowed solely for the installation of extensive scaffolding to access key areas.

We design, install and operate working platforms in a fraction of the time when compared when compared with the traditional scaffolding method.

Our dedicated team of structural engineers have a wealth of experience in designing these specialist access systems.

Ducting, Flues & Cyclones

Zenith has a wealth of experience in the inspection and maintenance of ducts, flues and cyclones both internally and externally. We have developed safe and innovative access methods to facilitate time saving inspections and repairs in confined spaces. In addition, we offer a comprehensive replacement service.

Our inspection services are overseen by our dedicated team of structural engineers.

Roofing Services

Utilising a combination of safe and innovative specialist access and scaffolding solutions, Zenith has a wealth of experience in carrying out a comprehensive range of roof maintenance repairs including full replacement. Our world class structural engineers design temporary works access solutions significantly reducing costs and time.

We carry out complex roofing projects throughout many industry sectors including cement plants, petrochemicals and the power industry.

Maintenance & Repair

Zenith specialises in carrying out repairs throughout all industrial, commercial and residential sectors. We provide all of the trades and skills required to maintain and repair buildings and structures. We work for the world’s leading companies ranging from petrochemical, power, steel and cement to academia, hospitals, local courts and much more.

Maintenance – Steelworks

Zenith has a wealth of experience in this essential field of activity. We have decades of experience in the maintenance and repair of structures across steelworks including industrial chimneys, natural draught cooling towers, flares and other tall structures.

Maintenance – Industrial Chimneys

The inspection, maintenance, repair and demolition of industrial chimneys remains our core activity. The successful external and internal refurbishment of these structures requires a thorough survey to establish the true extent of the repair work required. A full digital survey is the first stage in a five-phase operation that includes access equipment design, installation, load testing and repairs. We offer an online hot camera inspection as digital photography can reveal weaknesses and defects that require attention, for example to the interior lining and brickwork, baffle walls and flue inlets. Critically, it also enables engineers to plan in advance of a shutdown.

Structural Design & Remediation

We are able to generate 2D and 3D models from captured survey information and existing drawings. We can accurately determine revised capacities and assess the life extensions of existing structures and structural elements. Decay, loss of section, material properties, geometry and change of use are a number of variables that can affect the performance and life span of any building or structure. This can all be modelled to represent a snapshot in time and assist with determining the structural integrity of existing assets.

All of our software interfaces with our drafting resource allowing us to accurately schedule components for fabrication purposes or cost analysis. By merging this data with our software we can generate powerful and detailed 3D graphical representations of any structure, or structural element, to better present our analysis results to our clients. These models can also be used to assists in desk top reviews of operational requirements where lifting or sliding of complex fabrications require to accurately interface with (or bypass) existing structural components or services.

Conservation Works

We specialise in stonework refurbishment & repairs to buildings and structures. We have considerable experience undertaking complex restoration projects across the United Kingdom, utilising specialist rope access techniques, to preserve the original character and integrity of the stonework.

Our skills are also essential in protecting stone from the effects of adverse weather and natural ageing. Part of the Zenith Structural Access group of companies, we restore historic buildings, churches, bridges, viaducts and commercial properties, and are specialists in the conservation of listed buildings.

Bridge Works

Masonry, stone and wrought iron bridges gave way to reinforced concrete in the early 20th century. Up until then thousands of river, road and rail crossings across the UK were forged by traditional stone and masonry arch construction techniques.

Never having been designed to withstand the impact of today’s environment, the decay and subsequent weakening of these structures is beginning to cause concerns for the national transport authorities.

The key skills of our team at Zenith Conservation, and our Engineers Consultancy, are transferable to assist with identifying solutions for suitable repair, refurbishment and strengthening techniques of ageing masonry and stone (or composite) bridges.

We are able to work as principle contractor or as a specialist to the transport authorities. In addition we are able to provide a reactive service to repair damaged masonry or stone parapets caused by vehicle impact or similar.
