Building Making
Krisha Dharaiya | Semester 6 | 2022-23
Building making is a process that involves a series of steps beginning from briefing, surveying, designing, working drawings, preparing bills of quantities, tender approvals, site preparation, construction at various other levels and handing over. All these processes were studied in this course along with a detailed focus on working drawings and making bills of quantities. The design of this project was made in the previous module called Localization, where we prepared site drawings, fixed the programmes and designed the project with observations we made at the site. Working drawings for this project were prepared in this module along with the BOQs and assemblies of the materials.
Cheeta camp is a locality in Trombay, Mumbai located next to the Thane creek causing the region to have marshy soil, humid weather and also undulating land at certain places. The community toilet, balwadi and pathology lab are located between a series of houses on three sides and a road on the fourth. The space also includes a clinic and a balwadi. People of cheeta camp have settled here since the last 40-50 years.
The windows of this locality and buildings here allow different functions and
block certain programmes such as movement, vision, ventilation and security. These windows form layers for the users just like a filter that allows only the required vision or movement.
The filter currently is at an individual level, but what if there is a window to the community. This window filters out gaze for the people and allows movement for specific purpose. The wall for this window is the line of the road whose thickness slowly blurs as it gets into the community.
The walls forming the structure act as partitions in windows and allow the specific functions such as movement, vision and ventilation. The circulation in and through the building is directed by the walls and the spaces formed inside the structure also get defined by these walls.
The project is planned for 45 weeks from the demolition of the existing structure to barricading, foundation, plinth, walls, slabs, partitions, flooring and other fixtures. The project will be done in two phases, first one is the pathology lab and balwadi followed by the toilet block and garbage collection area. The unloading, storage for materials and lunch for workers is between the site and settlement which will later be made into a play space for kids in the day and parking at night.

SITE PLAN
Setting out of the points for excavation of the site- The datum chosen is the corner of an existing house.
Foundation plan- the raft, retaining walls, pcc bed, excavation pit, setback is marked in the plan at required offset
Structural Diagram- The beams tie the walls along and perpendicular to their spans below the plinth and are repeated on upper floors for the load bearing walls.
Ground floor plan- Pathology lab and toilet block are divided by a passageway for the vehicles to enter the settlement. A ramp takes you from the ground to the toilet block and stairs from the toilet block take you to the upper floors. The garbage collection area is connected to the road next to the toilet block. The circulation of the pathology lab forms by the walls. They lead to a double height common space which connects to all rooms.
First floor plan- Pathology lab is extended to the upper floor whose stairs are from inside the common space. Another set of stairs from the settlement brings you to the balwadi and classes on the first floor. The toilet block gets repeated on the first floor.
Second floor- The caretaker for the toilet block has a home on this level.
Roof plan- The overhead water tanks are placed on the roof level.
The section shows toilet blocks on ground and first floor above which is the care taker's home. On the other side is the pathology lab and balwadi separated by the double height passageway for the vehicles. All of these spaces are supported by 350mm and 230 mm thick load bearing walls which are connected by RC beams and slab over it. The beams pass through the walls and slab rests over the beams which the walls continue over each other centrally aligned.
The toilet block consists of 2 disable-friendly toilets and 24 toilet cubicles divided on two floors. These are divided with the use of PVC shutters on three sides and a ledge wall on the back. The walls are completely tiled with a wash basin between two sets of cublicles.
A steel staircase connects ground and first floor of the toilet block and continues to the second floor to the care taker's home and the terrace. The double stringer I- beam staircase has PCC plates as treads and SS circular hollow railing.
