Cento Engineering Group Ltd


Cento Engineering is the sole representative for Manntech GmbH (formerly Mannesmann Demag AG) in the provision of façade access and maintenance solutions for buildings and structures in the United Kingdom and Ireland.

Cento has successfully installed over 125 Manntech systems at more than 70 nationwide locations including many landmark buildings that have required innovative design solutions and major product development to meet exacting specifications. In addition Cento has extensive experience in providing systems for a variety of installations including PFI projects where a minimum of 35 year working life is required, additions to existing buildings with minimal or no structural alteration, environmentally positive “green roof” projects and low cost internal and external cleaning systems.

Since 1994 Cento’s expertise has seen its business grow steadily year on year to a position where it is acknowledged as a market leader and employs 15 specialist staff who provide design, project management, manufacturing, delivery, installation and maintenance services to the construction industry.

Cento Engineering employs 6 qualified Project Engineers who work closely with Manntech to produce the most practical and cost effective solutions for any given façade access and maintenance requirement.

Specifications require that buildings have full façade coverage and that building maintenance can be carried out with maximum efficiency and in total safety.

Cento’s Engineers work closely with Clients, Contractors, Consultants and Architects to ensure that the right types and numbers of systems are provided and that the interface with the building is as unobtrusive and sympathetic as is possible. Special attention is given to structural loading, positioning of track connections, safety requirements, interfaces with other trade packages and plant etc. to avoid expensive building modifications during construction.

Cento Engineering is always prepared to give honest and constructive advice to achieve the best possible solution.

Cento Engineering maintains an unrivalled reputation for delivering systems and solutions that work and provide a cost effective return on our customer investment.

55 years of supplying over 7,500 façade access systems to a world market gives Manntech/Mannesmann and Cento unparalleled experience and knowledge of what is possible and practical. To date all of Cento’s installations work to specification and have been completed without the customer incurring any charges other than those quoted.

Potential customers are encouraged to inspect previous installations, meet existing customers and undertake factory visits.

In recognition of Cento’s expertise and professionalism many clients are pleased to work with Cento on a negotiated contract or preferred bidder basis.

On receipt of an order Cento appoint an experienced Project Engineer to personally manage the Design, manufacture, testing, delivery and installation of each system according to an agreed schedule.

Working closely with the client the Project Engineer tackles the practical problems from track layout and interface with the structure and façade to compliance with health and safety legislation, industry standards and insurance requirements.

Prior to delivery clients are invited to witness the factory based performance test to ensure the operating parameters and specification has been met.

The Project Engineer liaises with the client and local authorities to facilitate delivery and installation including road closures, traffic management and mobile craneage etc. where required.

Installation and commissioning is undertaken by a specialist team of Commissioning Engineers who will thoroughly test the system and provide full operator training prior to hand over or in readiness for beneficial use during the construction phase.

Cento’s factory trained service technicians provide planned maintenance, statutory testing, risk assessments, operator training and a 24 hour emergency breakdown service. In addition where the client requires beneficial use of the system during construction a 3 monthly maintenance programme followed by complete refurbishment and recommissioning prior to handover is provided.

Manntech Building Maintenance Units range from simple standard twin jib designs to telescopic crane based systems with up to 45 metres outreach and counter balanced cradles for buildings with terraced, inclined, contoured, and set back facades with each system tailored specifically to the buildings they serve.

The modular nature of the range ensures tried and tested quality whatever the design, using components such as grooved drum hoist mechanisms with precision rope guidance for single or multi-layer winding capable of lifting suspended loads from 450 to 4800 kg and covering lifting heights of up to 465 metres.

In addition systems can be supplied with hydraulic lift-tables to raise and lower the BMU from concealed parking spaces, glass replacement units with up to 1000 kg capacity.
