Frequently Asked Questions
Can you make any alternative sizes?
Modular Prcast Systems is not limited to any module size. Modules can start from 3m wide to 14m long. alternative sizes can be manufactured for large projects – say 300 modules or more.Some dimensions can be altered, such as the roof depth and the internal ceiling height.
How many modules can be stacked up on top of each other?
The MPS system has been engineered to sustain the loads associated with 10 storey construction with the current modules sizes.
Are there any limitations to the opening sizes and locations?
The modules rely on reinforcing steel around the vertical corners (columns) and the horizontal sections just underneath the roof (beams) for the integrity of the system. These areas are also required to enable safe transport of the modules. Penetrations outside these zones are permissible.
What inclusions can be cast into the modules?
Generally, anything that will fit within the 90mm wall or roof sections with the reinforcing mesh can be cast into the modules. For example, PVC electrical conduits and wall boxes can be cast in for power and lighting. Hot and cold plumbing conduits can be cast in with spigots for attaching tapware etc. Floor heating coils, timber fixing points for shelves etc can be accommodated.
What are the thermal and acoustic properties of your concrete modules?
Concrete in combination with styrofoam post-fixed insulation provides exceptional thermal performance. See out technical data on thermal and acoustic performance.
Do you have any design examples?
Yes. Many of the projects that we have undertaken are available for download as plans and selected projects are covered in our projects section.
How are your modules transported?
MPS precast modules can be transported on standard flat-top semi trailers, drop-decks or machinery floats, however they must be moved using our transport beams. These beams ensure that the modules stay securely restrained to the truck tray and are essential for transporting the modules safely.
How much do the modules weigh?
The mass of each module depends on the number and size of the openings (doors and windows), however the modules typically weigh 12 tonne and 15 tonne for a 5m and 7m module respectively. This is based on 90mm walls and 80mm ceiling depth. Masses can be reduced by reducing the overall module height and by using light-weight aggregate (which can reduce the weight of the modules by around 16%).
How many modules can be transported on a single truck?
This depends on the overall capacity of the truck and trailer and transport regulations. Typically, 2No. standard 5m modules or 1No. 7m module can be transported on a single semi trailer. It is possible to fit a 7m and 5m module on the one trailer, provided the individual masses are reduced by either reducing the ceiling height or using light-weight aggregates.
What is a typical construction cost using these modules?
Construction costs can vary depending on location, saving up to 30% can be achieved.
Are the modules bullet proof?
Concrete is inherently good at withstanding attack from rifles and handguns. Testing is currently underway to determine the level of resistance to bullet attack as per the requirements of AS2343:1997.
What are the time savings when building with MPS concrete modules?
Time savings of 20% as a minimum can be made in on-site construction time using modular construction techniques. For example, the school toilet block project described in our projects section was installed onsite in 2 weeks. This included demolition of the existing structure and installation and commissioning of the new structure.
What is the structural performance of these modules?
Unlike traditional concrete structures where the columns hold up most of the axial loads, all the walls of the modular precast system perform as “shear walls” which translates to a highly rigid, stable and sustainable structure. It is also worth mentioning that these modules have a very impressive fire rating.
How do these modules hold up in case of an Earthquake?
Since the modules are made from 100% high strength concrete with reinforced steel along with the fact that the modules are poured as one monolithic element; the result is a structure that can handle high lateral and torsional forces. In plain terms, this system is suitable for Earthquake-Zone III countries.
How many modules can a crane set in a day?
Typically, this depends on project size, access and transportation. Given normal circumstances a crane can set up to 12 modules a day. This rate can easily be increased if the factory is on-site or close by, the project is easily accessible for trucks, and there are an adequate number of loading trucks available for quick turn-around times.
