Execution Planning For Construction of High Rise Building G+30

1. Start with the Basics: Site Survey and Soil Testing

Before anything, you have to get the site surveyed and perform soil testing. This will tell you the condition of the land, whether it’s suitable for a high-rise, and how deep the foundation should be.

If the soil is weak, you might need deep foundations like pile foundations.
The soil report will guide your foundation design, ensuring the building stands firm.

Example: Let's say the soil test shows that you need a 20-meter-deep pile foundation. You’ll now know exactly what kind of machinery, labor, and time it will take to complete this foundation.

2. Prepare the Construction Plan (Master Schedule)

Next, you need a Master Schedule for the project. This is like your project’s roadmap, showing all the tasks from start to finish.

Break down the project into phases: foundation work, structure (columns, slabs), brickwork, plastering, finishing, etc.
Allocate time for each phase. For a G+30 building, the structure work will take up a big chunk of the schedule.
Use tools like MS Project or Primavera to plan timelines, task dependencies, and critical paths (tasks that, if delayed, will delay the entire project).

Example: For G+30, you may plan around 2-3 floors per month for the structure. So, if you’re aiming for 30 floors, it could take around 12-15 months for just the structure, assuming you have smooth progress.

3. Resource Planning: Labor, Materials, and Equipment

Once you have the plan, now it’s time to think about resources:

Labor: You’ll need skilled workers like masons, carpenters, electricians, and unskilled labor for moving materials and cleaning up. You need to balance this carefully to avoid too many workers (which increases costs) or too few (which causes delays).
Materials: Plan your material procurement based on your project schedule. For example, when you start the foundation, you’ll need steel bars, cement, and aggregates for concrete. Later, you’ll need bricks, plaster, tiles, and so on. The key is to avoid stockpiling too early, as it takes up space and risks damage.
Equipment: Think about cranes for lifting materials to the higher floors, concrete pumps for pouring slabs, and machinery like excavators for foundation work.

Example: If you’re on the 15th floor, you need the crane to lift steel bars to that height. So, you’ll plan the timing and availability of the crane based on your floor construction schedule.

4. Foundation Work

The foundation is critical, and it has to be done right, as it supports the entire building.

Once the design is ready, excavation begins. For high-rises, deep excavation is common.
After excavation, you’ll lay the piles (if it’s a piled foundation) and then move on to casting the pile caps and the raft/slab foundation.

Example: If the soil test recommended a pile foundation 20 meters deep, you’ll need a rig to drill and place piles. Once done, you’ll pour concrete for the pile caps and raft foundation.

5. Superstructure: Building the Floors

Once the foundation is complete, you can move to the superstructure, which is the actual construction of floors.

Start with the columns and then move on to casting the slabs. This will be repeated floor by floor until you reach the top.
Typically, each floor has its own cycle: column work → slab casting → curing → start the next floor.

Example: For a G+30 building, each floor might take 7-10 days for casting and curing. By sticking to this cycle, you ensure smooth progress without too many interruptions.

6. MEP Coordination: Electricals, Plumbing, and Fire Safety

As the structure goes up, you also need to plan for Mechanical, Electrical, and Plumbing (MEP) work. These services have to be installed in coordination with the construction.

For example, before you cast a slab, the electrical conduits and plumbing pipes should be placed so that they don’t interfere with the structure later.
Fire safety for high-rises is also critical. So, provisions for fire hydrants, alarms, and emergency exits need to be planned early.

Example: If you’re on the 10th floor and realize that the plumbing isn’t aligned, you’ll face delays because now you might need to break the concrete or make adjustments. Coordinating MEP from the start avoids such issues.

7. Brickwork, Plastering, and Finishes

Once the structure is up, you move on to brickwork and plastering. This phase involves:

Laying the bricks for internal and external walls.
Plastering the walls to get them ready for painting or finishing.
Installing doors, windows, and other finishes.

Example: Let’s say you finish the structure and begin plastering. You need to schedule different teams for different tasks (like a team for brickwork, another for plastering), ensuring smooth handover from one activity to the next.

8. Finishing Work: Tiles, Paint, and Interiors

The final stage is finishing. This includes laying tiles, painting the walls, fixing false ceilings, and installing electrical fittings. You also install elevators, a critical part of high-rise buildings.

At this stage, you’ll focus on the details, making sure everything looks good and functions properly.

Example: Once the painting is complete, the electrical team will come in to install switches and lighting fixtures. Then, you’ll run final quality checks before handing over the building.

9. Quality Control and Safety

Throughout the project, you need to focus on quality control and safety. This includes:

Regular site inspections to ensure the work meets the design and safety standards.
Making sure all workers wear safety gear and follow site safety protocols.

Example: You might have a safety officer who conducts daily checks to ensure there are no hazards like exposed wiring or unsecured scaffolding.

10. Handover and Final Inspections

Once all the work is done, the final phase is the handover. This includes:

Conducting a final inspection with the client to ensure everything is in place.
Handing over documentation like warranty certificates, building plans, and compliance certificates.

Example: After inspecting the building and ensuring it meets all safety and quality standards, you’ll hand over the keys and close out the project with any final paperwork.
