Do You Need a Mobile Site Office?

“A mobile office is an office built within a truck, motorhome, trailer or purpose built shipping container. Most common are towable offices built on an axled iron frame for easy relocation. Mobile field offices are often found on construction sites, or at disaster scenes where a temporary office space is needed. Typically, mobile offices in North America feature a single phase split (240 volt center-tapped) electric service that is connected to a nearby source of power, to run small window-unit air conditioners, and the like. There are many types of companies that sell, lease, rent new and used storage containers, portable buildings or modular buildings. This type of construction shortens the construction period as the building can be built in a factory in as little as six weeks and the site and utility work can be done in conjunction with the construction of the building.

The term “mobile office” is also used for the workspace of salespeople or similar, working out of their company office. They are usually equipped with a portable computer and connect to the company servers and Intranet via mobile phones, WiFi or via fixed connections in cybercafes, hotels and airports.” Wikipedia

Site Office

“Construction sites will generally require office facilities to provide accommodation for site managers, provide space for meetings and to provide storage for site documentation. Site offices are often described as ‘site huts’ even if they are large and well fitted out.

It is important that site offices are comfortable, attractive and versatile, as well as being suitably robust and secure. Regulation 17 of the Construction (Design and Management) Regulations 2015 (the CDM Regulations) states:

‘A construction site must, so far as is reasonably practicable, have sufficient working space and be arranged so that it is suitable for any person who is working or who is likely to work there, taking account of any necessary work equipment likely to be used there.’

Each individual project will have different requirements for site office provision. On large projects separate offices may be provided for site foremen, engineers and the commercial and project management team.

As site offices are generally temporary in nature, only there for the duration of the construction works, they are often prefabricated, or constructed from portable, or modular, buildings, frequently referred to as ‘portacabins’ (although ‘Portkabin®’ with a ‘k’ is a trade marked brand name of Portakabin Limited). These are standard sizes and can be fitted together or stacked to form almost any configuration of accommodation required. They can include reception spaces, offices, meeting rooms, kitchens, toilets, showers, changing facilities, lockers, storage, and so on.

Site offices are easily transported on flat-bed trucks and set up on site using a crane. Typically they have four adjustable steel legs with attachments for stacking. Site office panelling is usually made of galvanised steel sheet and a rigid insulation core. A plasterboard inner lining is used for walls and ceiling. Windows are often designed to optimise light levels, with white walls and heavy-duty flooring that is easy to clean. Several manufacturers provide anti-vandal protection, such as pyro-shield windows with steel shutters and high-security steel doors.

They are often stacked with external metal stairs leading to the second floor. Large sites may have several inter-linked portable offices capable of holding hundreds of people, stacked up to three-storeys high with internal stairs and steel frame bracing.

They may be purchased or rented, and once construction is complete, either returned or take to a new site for re-use.”
