Pre packaged plant rooms

We at Holdens have been building pre packaged plant rooms that are fully BSEN1090 compliant, and are fully designed and built under our ISO2015:9001 quality system to customer requirements for a number of years.

There are many driving forces in the construction industry towards the use of fully packaged plant rooms,that deliver a “plug & play” capability which provides the optimum, most cost effective solution to almost any construction project.

The ability to deliver a unit that is constructed with all services fully installed, fully tested and ready for connection is presenting significant benefits to large and small construction projects as follows,

Work on building the plant room can run in tandem with main construction works.
This can deliver significant time saving to a project, whilst also reducing the number of on site workers, working within a particular area,thus reducing the potential for incident and accidents under site conditions.

Progress on building these units does not suffer from the influences of bad weather, other build related activaties, along with some of the health & saftey issues assosiated with constantly changing site conditions, or unforseen disruptions.

The construction of a plant room in a clean engineering facility, fully equiped with good lighting, insitu manufacturing plant, over head lifting equipment will invariably result in a better quality build / finished plant room.

It could also offer cost reduction benefit, when dirctly compared with “on site” instalation costs.

It offer accelerated delivery of construction projects.

It also potentially reduces the risk re health & saftey of workers due to outside forces.

All pipe work & electrical / power systems will be fully tested and certified ready to be delivered / arrive on site.

Heating & hot water generation plant:

Pumped systems & pipe work:
