Spaniel Row Mechanical & Electrical Capacities Report

We were tasked with establishing the capacities of the mechanical and electrical services at Frontline Recruitments proposed new offices at Spaniel Row, Nottingham. This case study shows how we worked with our clients to develop a capacities report. The first step was to conduct an initial site visit. We then carried out a detailed survey of the adjacent plant room.

Review of mechanical services

Potable Water. There were no water services within the proposed office area. The existing building had an insulated 63mm drinking water rising main that ran up from the main plant room, just outside the office walls. This could be connected into with a water meter and would provide sufficient water for the proposed development.

Air Conditioning. There was no air conditioning fitted. However, there was space on the roof for external condenser units to be fitted. There was also sufficient internal space to install a ceiling mounted internal evaporator units. It was noted that the west-facing wall on the 2nd floor was only a thin contour steel skin which has poor thermal qualities, which will add to the load on the air conditioning/ heating system. Therefore, it would need upgrading under Part L of the Building Regulations.

Ventilation. No ventilation system was fitted to the building, and it was noted that all the windows were sealed and could not be opened. To meet Building Regulations, it is likely that holes would have to be made in the building fabric to enable fresh air to enter the building.

Waste Water Drainage. There was no drainage installed on the first or second floors however on the ground floor waste water drainage ran from the hotel above to the car park wall. There was no low-level drainage installed therefore some excavation will be required if toilets and sinks were to be fitted on the ground floor and this would disrupt services within the hotel so some negotiation with Travelodge and the Landlord would be required.

Gas Supply. The proposed office did not contain any gas services however there was a rising main running upwards from the main plant room just outside the office walls. This could be connected into with a gas meter and would provide sufficient gas for a small water boiler/ heater.

Review of electrical services

Electrical Power. Within the adjacent plant room, there was a dedicated electrical power feed for the office area. This cable was capable of carrying 425 Amps per phase but would require the fitting of a suitable isolator and electricity meter.

Lighting. There was only one (inoperable) internal light that was powered from the hotel above, and there was no external lighting. There was lots of natural light on the first and second floor. However, the rear of the ground floor was shaded from natural light and was dark so special consideration needed to be made for lighting in this area. For the comfort of staff external or internal blinds should be considered for the large windows.

Data/ Telephone. There was no data or telephone connection within the proposed office area. However, the adjacent plant room had BT connections that could be utilized. Checks of the local IT infrastructure showed that ADSL feeds were available that provided 10mbps downstream and 1Mbps upstream speeds. FTTC was also available in the area.

Security/ CCTV. No security system or CCTV was identified within the building, and considering the buildings location, it was recommended that a security and CCTV system was installed.

Fire. No fire alarm system was identified within the building, however, fire exit doors were marked and operable. To comply with Building Regulations a fire alarm system, with a control panel close to the front door, was required.


In general, little provision had been made for electrical and mechanical equipment and some work on the building fabric needed to take place, i.e. digging ground floor drainage, core drilling concrete floors for service risers and making openings for ventilation. During the design phase, we suggested they considered the use of renewable sources of energy (roof-mounted solar panels, etc.) and better insulating the building to reduce the running costs.

There was sufficient capacity of all mechanical and electrical services to supply the needs of the office space. However, it was recommended that early contact was made with the landlord to discuss connections for gas, water and drainage as this will enable smooth implementation of the installation works.
