How StruEngineers & Aashi Solutions Delivered a Complex High-Rise Precast Project Using IMPACT BIM

About the project: Located in one of Pune’s most strategic commercial zones, M81 demanded a construction approach that could deliver speed, quality and certainty. While the project was initially planned using conventional RCC construction, the tight timeline encouraged the promoter to explore precast technology. Aashi Solutions was selected for its proven ability to deliver projects within committed schedules. The site brought its own complexities, including heavy traffic on the adjoining main road, limited space for handling precast elements and five basement levels requiring deep excavation with careful groundwater management. By adopting precast construction and partnering with a leading precast detailing company in India for expert precast detailing services in India, the project team overcame these challenges efficiently and delivered a high-quality outcome that met the promoter’s expectations.

By replacing spreadsheet-based workflows with a fully coordinated digital precast model, Aashi Solutions streamlined detailing, quantity reporting, production planning and site execution for a 25-storey commercial building in Pune, India. Utilizing professional precast detailing services in India and advanced structural precast detailing ensured a smooth transition from design to site execution.

Reinforcement Congestion at Critical Connections As the project developed, several complex precast beam column detailing junctions created severe reinforcement congestion. Traditional detailing workflows made it difficult to confidently visualise how reinforcement would interact at these junctions before fabrication. Without full 3D visibility, fabrication errors, production delays and site installation conflicts could potentially arise. Additionally, quantity management relied heavily on spreadsheets, making reporting and commercial tracking cumbersome. Leveraging precast engineering services and specialized precast detailing services in India was essential to overcome these hurdles.

Visualising What 2D Drawings Cannot Show Using IMPACT precast software for 3D reinforcement detailing alongside specialized precast detailing services in India, engineers could inspect every connection in three dimensions before production commenced.

The detailed model enabled engineers to:

• Perform accurate 3D rebar coordination

• Verify reinforcement placement

• Resolve rebar congestion

• Improve constructability

• Eliminate drawing ambiguities

• Reduce production risk

Rather than discovering issues during casting or erection, the team resolved them during modelling. This significantly improved confidence across design, production and site teams.

“The ability to visualise reinforcement interactions in 3D transformed how complex precast connections were detailed and manufactured.”

Automated Drawing Production Once the reinforcement was coordinated through precise precast detailing services in India and AutoCAD precast detailing, IMPACT automatically achieved precast shop drawing automation directly from the model. Benefits included:

• Consistent documentation

• Faster drawing production

• Reduced manual drafting effort

• Improved accuracy

• Better revision control

The result was a streamlined workflow from design through fabrication.

Accurate BOQ Reporting at Any Time Historically, quantity tracking was performed using spreadsheets. With IMPACT and accurate precast BOQ generation from precast detailing services in India, quantities became directly linked to the BIM model. This enabled instant generation of:

• Concrete quantities

• Reinforcement quantities

• Cast-in item counts

• Element schedules

• Production reports

For Aashi Solutions, this provided reliable data throughout the project lifecycle and enabled greater transparency when invoicing customers.

Digital Model Meets Factory Floor Because every element was modelled using precast BIM detailing before production, leveraging robust precast detailing services in India, manufacturing teams had clear information regarding:

This reduced uncertainty and improved production efficiency.

Planning for Site Constraints Before Delivery The project site presented practical challenges relating to element handling and erection logistics. Using IMPACT’s element information and weight control capabilities, combined with comprehensive precast detailing services in India, the team could evaluate crane handling requirements during the planning phase. This allowed:

• Better element segmentation

• Controlled transport weights

• Improved lifting strategies

• Reduced erection risk

Potential site issues were addressed before elements left the factory.

Delivering Under Tight Timelines For a high-rise precast construction project with restricted site access and demanding delivery schedules, conventional construction methods would have required significantly greater labour and longer execution periods. Adopting precast construction and partnering for high-quality precast detailing services in India provided:

• Faster structural completion

• Reduced dependence on skilled site labour

• Improved quality consistency

• Better programme predictability

For the client, the successful delivery demonstrated the practical advantages of precast technology and reinforced confidence for future developments.

Measurable Outcomes

The Aashi Solutions M81 project demonstrates how digital engineering and world-class precast detailing services in India can remove traditional precast bottlenecks long before production begins. By leveraging IMPACT for modelling, detailing, quantity management and planning, the project team established a seamless digital workflow that connected engineering, manufacturing and site execution. The result was a more predictable, efficient and scalable approach to precast construction, setting the foundation for future projects built on the same digital principles.
