Mechanical and Electrical M&E Engineering Design

As consulting engineeers, Callidus Design offer a full range of Mechanical and Electrical (M&E) engineering services. This also includes the combination of Mechanical, Electrical and Process Engineering which is referred to by the acronym MEP. Callidus Design's consultants provide design and support functions for a wide range of mechanical and electrical services. 

Mechanical Engineering Design Services

As Consulting Engineers, Callidus Design can provide a complete engineering design service for a broad range of mechanical building services. Projects ranging from small scale commercial to multi-million pound developments are within our design capability. Our past project experience extends across a diverse range of sectors, including Residential, Leisure, Commercial, Industrial, Education and Healthcare.

Electrical Engineering Design Services

As Consulting Engineers, Callidus Design can provide a complete engineering design service for a broad range of electrical building services. Callidus Design have project experience across a wide range of sectors including Residential, Leisure, Commercial, Industrial, Education and Healthcare. Previous and current projects range from small scale commercial developments to large multi million pound developments.

Controls Engineering Design Services

Callidus Design has extensive experience of the successful design, specification and installation of Controls Engineering systems such as Building Management Systems (BMS), Building Energy Management Systems (BEMS) and Process Control Systems including SCADA (Supervisory Control and Data Acquisition) for PLCs. Applications include those which provide environmental control, process control and central plant control.

Public Health Design Service

As Public Health Engineering Consultants, Callidus Design provides all steps of the design function for all Public Health services within buildings. These services are found across the Residential, Commercial, Industrial, Education, Sports, Leisure and Healthcare sectors.

Process Design Service

Process Services are the lifeblood of any facility which relies on those services for its key functionality. Callidus Design have amassed considerable knowledge and expertise in a very wide range of Process Engineering in a diverse number of applications and sectors. This gives Callidus Design the edge over our competitors when it comes to Process Engineering Design. Notwithstanding the functional performance of any Process Service, today's focus is just as likely to be on Safety and Efficiency. 

Building Services Engineering Design

Callidus Design's consulting engineers are experts in the field of Building Services Engineering. We specialise in the Residential, Commercial, Industrial, Education, Healthcare and Renewable sectors. 

Expert Witness Services

In the event of accident or failure of a Building Service resulting in secondary damage or injury, more often than not a forensic analysis is required to determine the root cause of the incident. This is particularly required when the incident leads to an insurance claim and the insurance company needs to be sure of their liability before settling the claim. To that end Callidus Design offer the role of Expert Witness.

 Psychrometric Design Service

Outwith ventilation systems for comfort only, some processes rely on environments in which the close control of both temperature and humidity levels are very important. It would be unusual for a building not to require fresh air ventilation and therefore the admission of external air into the building will alter the internal environmental conditions if left uncontrolled. The external ambient humidity level rises and falls hourly, diurnally and seasonally. Typically the external ambient humidity level is low in winter and high in summer. Therefore, in winter, moisture must be added to the air in the building and in summer it must be removed to compensate for the external changes. The addition of moisture is achieved through a process of humidification and the removal of moisture through a process of dehumidification. The science of moisture addition and removal is called Psychrometrics.

Cleanroom Design Service

A wide range of manufacturing processes and scientific research facilities require environments where a low level of contamination or pollutants are present, which could otherwise adversely affect the product or research process. These environments are known as cleanrooms, where contamination or pollutants are controlled to a specified “cleanliness” classification standard. The cleanroom classification standards for the UK are laid down in the European Standard BS EN ISO 14644-1 which dictates the requirement for specific particle count measurements and calculations to classify the cleanliness level of a cleanroom or clean area. The classifications range from ISO Class 1 (highest classification) to ISO Class 9 (lowest classification), which specify the number of particles (usually specified at a particle size of 0.1 µm or 0,5 µm) permitted per cubic metre of air.

Acoustics and Vibration Design Service

The design of all building services requires that any noise sources inherent within the design do not produce excess noise or vibration which may interfere with the intended use of the building or create unacceptable levels of disturbance to the occupants.

The initial selection of plant must be appropriate for the intended building usage and meet any maximum noise limitations stipulated by the client. This would typically apply to the selection of plant which is designed to move air or water through a building, i.e. fans, pumps and their associated distribution systems. For air distribution systems, the selection of ductwork, grilles, diffusers and dampers should be appropriate to maintain noise transmission and generation to acceptable levels. Similarly, for all pipework systems, the selection of pipework, valves and other inline components should be appropriate to maintain noise transmission and generation to acceptable levels.

Troubleshooting Building or Process Systems

Troubleshooting - not all building or process services operate in the way we would like them to operate. This can be because the preferred mode of operation has changed since the building or system was constructed. It can also be as a result of a flaw in the original design concept or design briefing which results in the system being controlled in a manner which is less than desirable. In a commercial building this may prove to be a great annoyance for the building occupants but in a process environment it can be potentially disastrous or at least very costly. This is where our unique Troubleshooting Service can assist in the resolution of this problem.
