US Military Gets into Shipping Container Building Construction
Militaries the world over love to construct buildings that are cheap, sturdy, and can be thrown up in minimal time. It is of little surprise, therefore, that they have recently discovered the benefits of repurposing shipping containers for their buildings. Shipping containers are very durable, can take a lot of weight and, thanks to being modular, can be built on site in very quick time indeed. Let’s take a look at their new 249th Engineers company operations building that has just been built at Fort Bragg, North Carolina.
The brief
The US Engineers needed a 5,000 square foot building that had to be built for less than US$750,000 and also needed to be built in quick time. The original contractors working in traditional construction methods just couldn’t build a building to within these parameters.
They then looked at modular construction. Modular construction is where much of the building is built off-site in factories and then installed on its foundations on site. The basic building can go up in just days once on site, and with the pre-fabrication it will have its electrics, water and mechanical features pre-installed, meaning that much of the First Fix phase of construction is done already.
The shipping container epiphany
The US Engineers saw that repurposed shipping containers was the way forward. Most shipping containers are only used once – they are made in China, filled with goods and sent to consumer markets around the world. Their design is such that they could take several trips around the world in all weather conditions, never mind just one trip of 5-7,000 miles. Consequently repurposed shipping containers are almost as good as new and in most cases have depreciated in cost by around 50% from new after only one trip. You can buy a 40ft high cube shipping container for less than US$3000 and it will be almost as sturdy as when it came out of the factory.
Nathaniel Hermann, the Corps’ resident engineer and the project champion said, “It’s highly unlikely that the structure of these buildings will rot or get moisture damage, and they’re less likely to grow mold or mildew. They’re stronger, longer-lasting buildings that are substantially less susceptible to moisture, wind and other elements.” The US Military expect this building to last 50 years with minimal maintenance.
Using shipping containers as building blocks is much better for the environment. It is estimated that melting a container down to re-use its steel costs around 8,000 kilowatt-hours of energy. Turning one into a fully clad, durable building will cost around 400kWh, or around 5% of the energy of melting it down.
The new Fort Bragg building
The 4,322 square foot, two storey Army Corps of Engineers building was built in just 110 days. The cost came in at around US$150 per square foot, well within the price tolerances of the US Army. They believe that as local contractors get used to modular construction the cost is set to fall dramatically as well, pushing the costs of building shipping container buildings to a very competitive price point and one that can be replicated across all of the US Military’s permanent bases around the world.
The US Army is quite used to having prefabricated buildings in theatres of war where a utilitarian look is par for the course. You don’t need something to look pretty when the enemy want to put holes in it. Fort Bragg, however, is on home soil and there are certain planning and appearance regulations that the building had to conform to. Again, it was clad and insulated to meet the requirements of the base, and has a similar appearance to the other buildings on this vast military base.
Looking at it from the outside the building doesn’t look as if it was a bunch of shipping containers dumped on site – instead it is a neat, comfortable looking base for the soldiers working there.
