At up to 200 metres tall and 100 metres in diameter, the repair and maintenance of cooling towers is often a complex and hazardous operation, particularly in gaining access to all elevations and orientations. Here, we have always been one step ahead of our competitors. Our ability to design and construct bespoke cathead systems that fit the precise cornice details at the top of the tower allows us access to all points of the stack via cradle access systems. This design capability, coupled with our experience in carrying out concrete repairs that prolong the working life of the towers, gives us unrivalled expertise in this demanding environment.
Zenith provides a comprehensive concrete repair service for reinforced concrete structures including small area repairs, crack injection, spalling repairs, FRP repairs including the reinstatement of larger defective areas.
Utilising a combination of specialist access and standard access, designed by our structural engineers, we install safe temporary works to be enable time saving and cost effective solutions.
Where access proves onerous, Zenith specialises in the painting of structures including industrial chimneys, natural draught cooling towers and other tall structures. We implement a variety of specialist access techniques to provide safe and cost effective solutions.
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.
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 petrochemcial, power, steel and cement to academia, hospitals, local courts and much more.
We have a wealth of experience in providing all of the skills and trades necessary to carry out the erection of complex structures including section replacement. We employ specialist access to safely overcome the most demanding of tasks.
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.
In conjunction with our engineering, design and modelling capabilities, Zenith Consultants are able to offer solutions for complex rigging and lifting projects.
As full members of the Lifting Equipment Engineers Association, LEEA, we design and detail bespoke fabrications and solutions to our international customer base.
Where precise control, movement and weight measurement is required we are also capable of designing hydraulic lifting and sliding systems.
From our core values – Design, Innovate & Excellence, our ability to solve technical challenges presented from unusual requests is exemplary. We are, on a day to day basis, continually seeking for new ways to overcome the most complex of engineering challenges.
From providing bespoke access and support solutions over some of the most historical structures in the city of Edinburgh and beyond to designing temporary access decks to large marine jetties, we are continually looking to innovate our designs by utilising modern access techniques and material.
Due to our experience and exposure in the industrial sectors we fully understand how down time and outage works affects process and cost. We aim to complete our designs with the minimum disruption at site level and interface closely with the Clients operations teams to fully understand the design brief from the outset.
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.
