BIM offers essential support for contractors throughout various work stages, enhancing efficiency, collaboration, and profitability. Here’s how BIM can assist you:
1. Planning and Visualization:
Visualize the Project: A 3D BIM model allows you to see the entire project before construction starts, helping you understand design intent, identify potential issues, and plan effectively.
Simulate Construction (4D BIM): By connecting the model to a schedule, 4D BIM simulations depict the construction timeline, allowing you to:
- Optimize workflows: Identify bottlenecks, refine logistics, and enhance efficiency.
- Improve trade coordination: Ensure that all teams work from the same data to reduce conflicts.
- Communicate clearly: Convey the construction plan to stakeholders, including owners and subcontractors.
2. Coordination and Clash Detection:
Detect Clashes: BIM software automatically identifies clashes between building systems, helping avoid costly rework.
Coordinate with Subcontractors: Sharing the BIM model ensures all parties have consistent information, facilitating early resolution of issues.
3. Quantity Takeoff and Cost Estimation (5D BIM):
Accurate Quantities: BIM provides precise quantities of materials, labor, and equipment, leading to:
- Reduced cost overruns: More accurate estimates lower the risk of bidding too low.
- Improved bidding: BIM-based takeoffs enhance competitiveness.
Track Costs: 5D BIM links cost data to the model to:
- Monitor real-time costs: Spot potential overruns early.
- Analyze design changes: Quickly assess financial impacts of revisions.
4. Prefabrication and Modular Construction:
Design for Fabrication: BIM aids in designing components for off-site fabrication, enhancing efficiency and quality.
Precision Assembly: Accurate BIM data ensures seamless integration of prefabricated components, reducing installation time and rework.
Support Lean Construction: Prefabrication aligns with lean principles, facilitated by BIM data and coordination.
5. Site Management and Communication:
Access Information On-Site: Mobile BIM apps provide workers with real-time model access, reducing reliance on paper and enhancing office-field communication.
Track Progress: Use BIM to monitor construction progress, manage materials, and maintain schedules.
Field Layout: BIM data enables precise layout execution using total stations, laser scanners, or augmented reality.
6. Handover and Facility Management:
As-Built Model: Deliver an as-built BIM model to the owner, creating a complete digital record for future maintenance, adding value to your services over competitors.
7. BIM-Enabled Process Change:
Leaner Construction: BIM promotes lean techniques by:
- Reducing waste: Minimizes rework, delays, and material waste.
- Improving workflow: Facilitates smoother construction processes.
- Enhancing communication: Strengthens collaboration among project teams and subcontractors.
Paperless Construction: BIM advances the industry toward a paperless environment, improving information accuracy and reducing reliance on drawings.
Building Information Modeling (BIM) offers numerous benefits for contractors, going beyond traditional construction methods.
Some benefits as: enhanced facility management post-construction, better project control and reduced waste, etc make BIM an essential tool for contractors aiming to improve their project delivery, efficiency, and profitability.
I think, the additional benefits of BIM-based technologies for contractors can be obtained with the use of automated technology of construction and reconstruction management AT "Building Manager".
AT "Building Manager" is not one software product, but a system of interconnected software products of different developers, designed to achieve a main goal:
- Maximum automation and information linkage of all divisions of the design and construction organisation into a single system with complex and dynamic resources – time – costs estimation.
The creation of this automated technology required considerable efforts from developers of all software complexes included in AT, from the development and coordination of information exchange protocols to the development of special software.
Joint operation of software complexes of different purposes within the framework of a single system not only systematised all information flows against the background of significant reduction of labour intensity of separate processes (for example: calculation of estimates or formation of network organisational and technological model of construction for calculations of calendar plans) with the significant increase of information reliability level, but also has opened such opportunities, which were unavailable when using these software complexes separately.
Such capabilities include 4D-visualisation of the construction process (three-dimensional display of the construction object on any day of the calendar plan with or without the fact of work execution).
Inclusion or not of different software complexes in AT "Building Manager" is not regulated by any contract between developers, but is determined by functional capabilities of software products to provide import and export of information with the use of information exchange protocols accepted in AT "Building Manager".
One of the project managers said that after BIM all the project staff are satisfied since everything is modeled so there are no surprises that could happen during the construction phase. The morale of all stakeholders is good.
One particular project that comes to mind is a large commercial building we constructed in the city center. The design was complex, with curved lines, irregular shapes, and multiple stakeholders involved. We knew it would be a challenge, but with BIM, we were able to:
Identify potential clashes and errors before construction began
Collaborate seamlessly with architects, engineers, and subcontractors
Visualize the project in 3D, ensuring everyone was on the same page
Make changes and adjustments in real-time, without delaying the project
The result? We completed the project 10% under budget and 2 months ahead of schedule. The client was thrilled, and our team was proud of what we'd accomplished.
BIM has revolutionized the way we work. It's not just a tool; it's a mindset shift towards collaboration, precision, and efficiency
