With so much new infrastructure being built, Entec’s latest initiative – Mobile Plant Rooms – is increasing the speed, safety & quality of roll-outs.
It’s no secret there’s a lot of new infrastructure being built in New Zealand. The public sector is busy with projects such as transport and three waters, and the industrial sector with greenfield and brownfield expansion projects.
Entec’s latest initiative – Mobile Plant Rooms – is increasing the speed, safety and quality of these infrastructure roll-outs.
What is a Mobile Plant Room?
Quite simply, a mobile plant room is the packaging of plant into a portable enclosure.
The enclosure is built and fitted out off-site, inspected and tested, and then transported to site for rapid ‘plug-and-play’ installation and commissioning.
These are also commonly known as “E-houses”, but we prefer the term “mobile plant rooms” because there’s much more to them than just electrical plant.
In the past few years Entec has been involved in designing and manufacturing around 20 mobile plant rooms to house low-voltage MCC’s, control panels and operator desks, process plant and medium-voltage switchgear. Our client base has included water utilities, mining sites, power stations, ports, electricity networks and oil & gas operators.
Most of the mobile plant rooms we’ve built are based on ISO shipping containers, both 20 foot and 40 foot.
Several have involved two containers joined side-by-side to provide an internal width of 4.8m, which is ideal for switchgear installations where large clearances are required.
We’ve also built modular rooms from EPS sandwich panels, which provides total flexibility for dimensions.
Case study: What are the savings?
A recent client needed two low-voltage substations on a large industrial site to power around 1,600kW of electric motors via variable speed drives.
There was an intensive and complex multi-disciplinary construction project underway, and it made sense to have the bulk of the substation work carried out off-site.
The substations were built at Entec’s yard in New Plymouth and then transported to site for installation and commissioning.
Our estimate of the productivity, safety and environmental savings achieved on this project include…
- 1,200 man-hours of time not spent on the busy construction site.
- 240 man-hours not spent on the road travelling to/from site.
- 9,000 kilometres of mileage saved, along with 1,800kg of CO2 emissions.
- Around $26,000 in cost savings for accommodation and meals, let alone the labour savings through better productivity in the workshop.
In-house switchboard manufacture… single-source responsibility
Another excellent competitive edge that Entec brings to these projects is its in-house switchboard manufacturing division, branded as TCE Controls.
TCE Controls designs and builds MCC’s (including Cubic type-tested switchboards), control panels, distribution boards and all manner of other electrical panels.
Incorporating TCE Controls panels into an Entec mobile plant room provides a single contact point for clients. It also provides reassurance that the panel and room fit-out aspects of the build are perfectly coordinated.
What is the process?
Most of our projects start with a simple concept plan based on the new plant requirements. Entec can quickly provide a layout drawing and a budget estimate.
The detail of these jobs includes personnel access/egress requirements, air-change and cooling loads, paint specification for longevity, and the optimal cable access to make site integration as simple and safe as possible.
With a confirmed order, Entec produces detailed drawings for construction approval.
We encourage client visits to Entec during the build to keep up with progress, and of course we can supply regular programme and photo updates throughout. We also encourage factory acceptance testing at our premises prior to transport to site.
Completed mobile plant rooms are accompanied by extensive QA dossiers, including structural engineering information for the construction of foundations and tie-down arrangements, and for the planning of safe lifting.
But wait, there’s more…
We haven’t yet included a set of steak knives but our typical mobile plant room includes…
- Integral base-frame incorporating the cable support system, allowing easier cable access on site.
- High quality marine paint systems for longevity.
- HVAC system.
- Fire, smoke and gas detection systems.
- Commercial grade vinyl flooring.
If you have plans to install new switchboards, control systems, process plant or substations then give some thought to the advantages of a mobile plant room.
