Pre-cast concrete construction projects are becoming more popular in India. Because of the
requirements for build-ability, pre-cast construction has currently been adopted for
infrastructure projects and urban transportation. Right now, even the quality delivery of
project-specific pre-cast construction is required. The fastest-growing demand in the built
environment in the dwelling and office segments suggests that general pre-cast can also
advance. With a few case studies involving the author, the current study covers the planning
facets of such pre-cast construction in the General Pre-cast scenario.
Planning
The four fundamental parts of planning that are presented are production plant,
transportation, erection, and joint treatments
Production
The availability of the following data and capacity is a crucial planning factor.
Pre-cast suppliers who can make some or all of the following components.
Pre-cast suppliers who can make some or all of the following components.
- Columns
- Spandrels or inverted tee-shaped beams
- Structural wall panels and wall panels with lights
- Single tees, double tees, and hollow core slabs
- Stairs
The second crucial capability is the vendor’s current facilities’ production capacity, which are
located 50 km or less away from the project’s proposed site
Logistics and Handling
The approach roads must have the capacity to accommodate 40 MT trailers in the radius for
access to the site. Additionally, cars with the necessary capacity must be easily accessible.
Complete site access with adequate space for trailers to park and operating space for the
cranes shall be available. The election shall be planned in such a way that the crane boo
operating distance shall be available. Lifting hooks, loops , sling of HT cables shall be
designed for handling.
Essential Precast principles and standardized rules
The buildability, economy, and standardisation of precast components serve as the
foundation for precast building concepts. Precast element removal, storage, transportation,
and erecting techniques should get special consideration.
There are other secondary factors that should be taken into consideration as well, namely:
- The planning and execution of the installation sequence have a significant impact on how quickly precast construction is completed.
- In order to ensure that the components are quickly built, the crane is essential.
- The crane's position in relation to the positioning of the last panel.
- Delivery effectiveness is crucial.
- Must take into account the following advice, especially for precast concrete components
- Timely arrival.
- Deliveries of the right parts were made on schedule, provided without damage components.
