Heritage

Our engineers have extensive experience on projects across the UK, dealing with boroughs’ planning committees, Greater London Authority during project development stages and construction supervision phases. These types of buildings require sensitivity in understanding how buildings can be adapted to meet the needs of the 21st Century, whilst retaining the important cultural and heritage of a historic building.

Admiralty Arch is a large office building in London which incorporates an archway providing road and pedestrian access between The Mall, which extends to the South-West, and Trafalgar Square to the North-East. It was designed by Sir Aston Webb, constructed by John Mowlem & Co and completed in 1912.
Our engineers were responsible for the complete refurbishment and fit out of these Grade-I listed buildings which date back to 1786. The combined footprint of the interconnecting buildings is some 380,000 sqft.
The single end user will be the Cabinet and their support staff and the aim of the project is to create a modern and efficient environment within the confines of these fine historical buildings. Considerable coordination and discussion are taking place with all interested parties to ensure these buildings function and operate as a total unit.

Gray's Court is one of the most historic buildings in England. This ancient house was the residence of the Treasurers of York Minster from the 11th century until the latter was despoiled by Henry V111 in 1547.

 

The present owners have commenced an extensive programme of renovations to Gray's Court. Now completed, the house offers luxurious boutique accommodation in twelve en-suite rooms and guests are able to relax in the drawing rooms and Jacobean Long Gallery that have seen so much history.

 

Directors of CD International were appointed to provide building services to accord the requirements of English Heritage.

One of the most important challenges facing churches today is providing sufficient comfort for the many different users of the building, from worshippers to staff to visitors.  Church buildings have increasingly become a burden for congregations as escalating maintenance and energy costs threaten to consume any budgets. 
The proposal was to create two separate zones for heating and cooling. Adjacent space to be converted into a winter chapel and an office space for the priest, whilst main church space’s systems to be upgraded and function for larger type congregations and functions. This arrangement would significantly reduce heating costs as the entire church space would not be heated.
We have provided options study for the space heating, including specifications and cost estimation of the equipment: condensing boilers, radiators, under floor heating.

Built at the end of the last century, the Hotel Russell is one of London's most impressive Victorian buildings with many outstanding architectural features. Hotel has undergone a million pound refurbishment programme and boasts 357 en-suite bedrooms, including 160 air conditioned guest rooms, 15 Conference and Banqueting rooms.

 

Our engineers were responsible for the full design of the Mechanical, electrical, Public Health and Lift services.

 

Four floors and all conference rooms were refurbished to Art and Tech specification. Refurbishment of lifts was performed with sequencing to maintain the operation of the Hotel. Relocation of existing MEP plantrooms was fully coordinated to suit planning and English Heritage requirements. Inverter driven VRF were implemented to provide an option for simultaneous heating and cooling in different part of the hotel.

 

All works were design and installation coordinated while the hotel stayed operational.

Royal Connaught Park -  A unique development of luxury apartments set within a Grade II listed building and with over 100 acres of mature parkland. The group of buildings was until recently occupied by The International University-Europe, and for 70 years prior to that it was home to The Royal Masonic School for Boys.

 

A project was a combination of refurbishment of listed buildings complimented with new build to provide 450 residential units.

 

The site includes new leisure complex and new infrastructure services across the whole development co-ordinated for phased completion/handover. CDI engineers provided a new on site services infrastructure, integration of modern services and IT systems within listed buildings and site wide security systems.

Bushey

The second oldest residence in the UK is to be refurbished to provide 4,000 sqm of accommodation.

 

Due to historic sensitivity of the building and surrounding we are using ground sourced bores to provide the heating and cooling to the main property.

 

A new great hall is to be constructed with a basement swimming pool. The main ventilation plant has to be carefully coordinated to minimise plantroom space and noise from the equipment.

Roydon Hall
Tonbridge

The project was a refurbishment of guestrooms and reconfiguration of public spaces to improve circulation. This involved space planning, new air conditioning systems and integrating new distribution systems within the interior design.

 

>Works required close liaison with English Heritage on the integration of new services within listed areas. This included taking the Palm Court back to its original design based on historic photographs.

 

The guestrooms have been refurbished to the art and tech style with plasma screens and power jet showers.

 

Heating provided by 1.5MW central boiler plant. Installed cooling capacity for bedrooms - 800kW. Electrical infrastructure required a new IT backbone to each guestroom and there was a complete upgrade of fire safety system.

Renovation and conversion to residential accommodation of Grade II listed buildings. The restoration has been carried out to preserve the original historic appearance, character and features of the buildings.

 

Upon the development there were various non-listed buildings which were demolished to make way for the construction of new residential accommodation. These buildings were constructed in sympathy with the restored original buildings.

 

The progression of incoming services strategy was carefully developed and integrated with the new and existing buildings. This was to safeguard and minimise the visual impact and to ensure that the historic attributes were maintained.

 

CDI engineers provided incoming services strategy for all utilities to service the development.
