Real-World Results for Our Clients
We measure our success by the success of our clients. Explore how we've helped engineering and construction firms overcome challenges, improve efficiency, and achieve their project goals.
Scaling Capacity for a Large Commercial Project
Client Overview: A mid-sized MEP engineering firm based in Texas, USA, specializing in commercial and mixed-use developments. They had a strong reputation but a lean in-house team, which limited their ability to bid on larger, more complex projects.
The Problem: The firm won a contract for a large office complex but lacked the immediate manpower to handle the extensive HVAC BIM modeling required within the tight project schedule. Hiring and training new modelers locally was too slow and expensive.
Key Challenges:
- Urgent need for 5+ skilled Revit modelers.
- Maintaining high-quality modeling standards.
- Coordinating with the US-based design team.
- Meeting an aggressive project deadline.
Our Solution:
LiveHelpIndia deployed a dedicated, managed team of five senior Revit modelers within 72 hours. We established a secure, shared work environment and a communication protocol with a 4-hour daily overlap for real-time collaboration.
- Provided a dedicated team skilled in US standards.
- Implemented a 24/7 work cycle for rapid progress.
- Assigned a project manager as a single point of contact.
- Conducted daily progress meetings and weekly reviews.
"LiveHelpIndia didn't just give us draftsmen; they gave us a strategic advantage. Their team was skilled, responsive, and integrated perfectly with ours. We delivered the project ahead of schedule and under budget, which was a huge win for us and our client."
Enhancing Shop Drawing Accuracy for a General Contractor
Client Overview: A large general contractor in California specializing in high-rise residential and healthcare facilities. They managed multiple subcontractors for various trades, including HVAC.
The Problem: The contractor was experiencing significant project delays and cost overruns due to inaccurate and poorly coordinated HVAC shop drawings from their subcontractors. This led to frequent clashes on-site, extensive rework, and disputes.
Key Challenges:
- Inconsistent quality of shop drawings from different subs.
- Lack of proper clash detection before construction.
- Delays in the drawing approval process.
- High costs associated with on-site rework.
Our Solution:
We proposed a centralized model where LiveHelpIndia would create all HVAC shop drawings for their projects. Our team worked directly from the design documents, creating fully coordinated, clash-free 3D models and generating shop drawings from this verified source.
- Established a single source of truth for all HVAC shop drawings.
- Performed rigorous, multi-trade clash detection in Navisworks.
- Standardized drawing formats for clarity and consistency.
- Streamlined the RFI and submittal process.
"Centralizing our HVAC shop drawings with LiveHelpIndia was a game-changer. The quality and coordination are night and day. Our site supervisors can finally build with confidence, knowing everything will fit. The reduction in rework alone has paid for the service many times over."
Achieving LEED Gold with Expert Energy Modeling
Client Overview: A boutique architectural firm in the Pacific Northwest known for its focus on sustainable design. They aimed to achieve LEED Gold certification for a new corporate headquarters project.
The Problem: The firm's expertise was primarily in architectural design and materials, but they lacked the in-house specialized skills for the complex HVAC energy modeling and simulation required to maximize points for the "Energy and Atmosphere" LEED credit.
Key Challenges:
- Complex energy modeling to prove performance.
- Evaluating the ROI of various high-efficiency HVAC systems.
- Lack of expertise in IES VE and EnergyPlus software.
- Preparing detailed documentation for LEED submission.
Our Solution:
LiveHelpIndia provided an on-demand energy modeling specialist. Our expert worked closely with the architects to model the building and simulate the performance of different HVAC options, including a geothermal system and ERVs. We provided detailed analysis and reports to guide their design decisions.
- Conducted ASHRAE 90.1 baseline and proposed design modeling.
- Provided comparative lifecycle cost analysis for different systems.
