Modern Methods of Construction Flashcards
Features of traditional construction methods (7)
- Loadbearing walls/onsite construction, 2. Non-framed buildings, 3. Massive materials/labour intensive, 4. Low efficiency, 5. Slow, 6. Quality control issues (In-situ construction), 7. Construction waste
Features of MMC (8)
- Non-loadbearing walls/offsite construction, 2. Saving materials and labour, 3. Fast, 4. Higher efficiency, 5. Quality assurance, 6. Reduced waste, 7. sustainability
Off-site construction techniques (7)
- Volumetric modules (prefab concrete), 2. Panelised systems, 3. Hybrid systems, 4. 3D concrete printing, 5. Light Gauge Steel Framing, 6. Cross Laminated Timber (CLT), 7. Smart construction technologies
Volumetric modules (prefabricated concrete)
Entire rooms or sections of buildings are manufactured off-site as complete modules. These modules are ready-made rooms transported to the construction site for assembling. (popular for bathrooms and kitchens) (modules - ready made rooms) AKA pods
Panelised systems
Walls, floors, roofs are assembled into panels off-site, then transported to the site and connected to form the building’s structure. EG curtain walling, infill walling
difference between volumetric modules and panelised systems?
Volumetric is 3d and panels are a 2D plane with a certain thickness
Hybrid systems
The concrete in construction is the combination of precast and insitu concrete. Combines various materials and construction techniques to create customised modular solutions. A mix of volumetric modules, panelised systems, and other prefabricated components
Concrete 3D printing
Large scale 3D printers are used to print concrete structures layer by layer for constructing walls, bridges, and other structural components.
Light Gauge Steel Framing (steel framing systems)
Pre-engineered steel components are manufactured off-site and assembled on-site to create the structural frame of the building. Popular for residential and light commercial construction
Cross Laminated Timber (CLT)
CLT panels are manufactured off-site by layering and gluing together dimensioned lumber. On site these panels are assembled into the structural elements of a building
Smart Construction technologies
BIM (building information modelling), digital twin (a bit like bim but includes real time data and analytics) , industry 4.0 + AI, VR, AR
Modular construction
Factory produced building units that are assmebled as large volumetric components of a building. Used in hotels, education, student accomodtion,
Pods
Small, complete volumetric rooms. Usually non-structural and used within a loadbearing structure. The enclosure can be of steel frame, timber frame, concrete or composite constructions. Typically bathrooms
Panelised systems - open panels
Panels delivered to site where windows, services, linings are fitted. All structural components are visible
Panelised systems - closed panels
Like open panels but can have windows and doors. Internal structural components can only be seen around perimiter of panel
