How is modular construction impacting Project timelines?
Modular construction is significantly reducing overall construction timelines compared to traditional methods. Here are the key ways it's impacting project schedules:
Simultaneous on-site and off-site work: Modular construction allows for concurrent processes, with modules being manufactured in factories while site preparation and foundation work occur on-site. This parallel approach can reduce project timelines by 20% to 50%.
Examples: Use of Prefabricated Concrete Panels to be used for walls, thus replacing masonry or structural steel.
Factory-controlled environment: By moving 60-90% of the construction work to a controlled indoor setting, weather delays are largely eliminated. This leads to more predictable and shorter production schedules.
Rapid on-site assembly: Once modules arrive at the construction site, the assembly process is much quicker than traditional building methods. Some modular projects can be erected in just a few days to a few weeks.
Reduced design changes: Modular construction requires more upfront planning and design work, which helps minimize costly and time-consuming redesigns during the construction phase.
Standardization and repetition: The use of standardized components and repeated processes in factory settings increases efficiency and reduces time spent on individual tasks.
Just-in-time delivery: Proper coordination allows for modules to be delivered to the site exactly when needed, reducing storage time and streamlining the construction process.
Simplified on-site work: Since most of the construction is done off-site, the on-site work is primarily focused on assembly, which is generally faster and more straightforward than traditional construction methods.
Practical Applications
Use of Dincel Walls like for Residential construction has proven to significantly accelerate overall timeframes, whilst achieving Waterproofing Warranty from the manufacturer. (Home | Dincel Structural Walling - Permanent Formwork)
Use of Prefabricated Vertical Lifts only require 2-3 weeks of onsite assembly and commissioning, compared to 1-2 months with traditional methods.
Use of Prefabricated Rangehoods have helped us achieve quicker timeframes and less work on site for provision of commercial rangehoods particularly in Cafes and Restaurants.
Use of Prefabricated Building modules like the one’s offered through Ausco have greatly assisted Schools in achieving urgent classroom requirements, whilst new buildings were constructed. Ausco offer a range of options for Offices, Classrooms Aged Care and more. (Portable Classrooms & Modular School Solutions | Ausco)
The impact on timelines can be substantial. For example, some companies have reported delivering modular building projects in as little as six weeks from the order date. However, it's important to note that the actual time savings can vary depending on the project's complexity, size, and location. Overall, when implemented effectively, modular construction offers the potential to significantly compress construction schedules, allowing projects to be completed in about half the time of traditional construction methods.
