Are you pondering about the suitability of precast concrete structure to your construction projects but are not quite sure how to evaluate its benefits? Do you need a clear cost calculation and a plan for the most suitable precast products for your project? If this sounds familiar, concept design services will help you in adopting the precast concrete technology.
Shift from traditional construction to precast
If you are new to precast construction or would like to expand your knowledge, a concept design will help understanding the feasibility of adopting this technology. A concept design includes an evaluation on how your current and foreseen projects could be structured using precast and whether to use complete or composite structures. The performance of the precast building in the local ground conditions and the required precast product types are also evaluated.
One good example of concept design is Jindal Reality (JRPL), our Indian customer, who turned to Elematic for adopting precast technology in their project: The Jindal Global City and University at NCR, India. For the project, they were exploring which construction technology would fulfil the requirements of rapid construction, high quality and less labor oriented work, and how to adopt it. We carried out concept design for their building requirements, which provided details of how precast can be implemented and their construction methodology converted. As a result, JRPL successfully finished the construction project of a number of 6 to 9 storey tall precast buildings, taking up to approx. 1,000,000 m² of construction. These buildings are complete precast structures comprised of wall-frame system giving better utilization of floor area compared to conventional construction, in high seismic zone-4 of India. JRPL reached all their set requirements.
Choose the most suitable concept design office
When taking up a new construction method, it’s extremely important to find a professional partner that can truly help you in reaching the best possible outcomes. If you are considering which structural engineering services provider to choose in the precasting field, you should pay attention to the following issues on top of the critical concept evaluation itself:
- Do the design engineers have sound know-how on developments in the precast industry along with good practices of successfully implemented systems?
- Have they gained experience on geographically varied projects, international structural standards and utilization of varied programs?
In addition, the engineers should have solid knowledge on precast production, plant operations and efficient working methods, as well as structural connections and their life time behavior as one of the most crucial aspects.
Preparing for concept design project
Understanding the nature of your project in totality is crucial for the concept design team, because it’s the starting point for evaluating the suitability of precast to the project. To reach the best possible outcome, the team needs to receive architectural drawings, including layouts, elevations, sections and special features – if any. In addition, details of building utility services arrangements, local seismic details and costs of local structural materials are needed.
The concept design phase usually takes 8 to 10 weeks to complete. However, all projects are unique in terms of architectural complexity, seismicity, geographical location and other construction requirements; hence a precise time for the designing phase cannot be provided before knowing all the details affecting the design.
The end result of a concept design project is a report including all information that you need for adapting precast construction:
- Basis of structural analysis & design including e.g. loading data, design code details and structural framing concept details
- Outlined structural framing with precast arrangement
- Typical connection details of various precast elements
- Sizing, geometrical details and number of different precast product types including reinforcement, prestressing and concrete strengths
- Suggested changes to architectural design to make the building more efficient with precast system
- Details of production set-up / precast machinery and equipment requirements
As an example, one of our customers in concept design is KEF Infrastructure, constructor of PMHS Hospital as one of their first precast projects in India. When we got involved with KEF, they were already exploring precast technology for their project. The suggestion they had at that time was rather old-fashioned and labor intensive, with complex production and execution. If the original plan was followed, the project would have been costly and time-consuming with questionable end results.
We carried out concept design for the hospital building, giving details on how modern precast concrete technology can be implemented with efficient precast element requirements. We also gave advice on how to set up a productive and very flexible production system, which will cater to the various project needs in the future.
As a result, KEF was able to set up a productive and cost-efficient solution for the challenging hospital project comprising of 300,000 m², located in seismic zone-3 of India. The structural system comprised of multi-storey reinforced precast columns, prestressed precast beams, hollow-core slabs with structural topping, staircases and special- featured graphic concrete façade panels. The PMHS hospital is a unique building in India, constructed with complete precast solution meeting all desired project requirements.
After you’ve gained in-depth knowledge about the precast construction technology and its suitability to your project, the next step is to discuss more about the structural system, suggested architectural changes, project costs and precast production set-up requirements. On top of the feasibility study, we will help you in finalizing the building details and setting up precast plant – we promise lifetime commitment – from design to the complete lifecycle of the factory.
