SITE ANALYSIS Residential

Wind is blowing from South-West (SW) to North-East (NE).

­ ­ The diagonal layout had the advantage of the building being oriented towards the south-west breeze. The orientation also helps to cut out the west sun reducing glare.

ACADEMIC BLOCK ( OLD CAMPUS )

KEY PLAN

N CLASSROOM & SEMINAR ROOMS Consists of 6 classrooms and 5 seminar rooms linked by a wide passage with semi-open spaces in the old campus. The semi-open spaces act as transition point between double height corridor and classroom.The corridors also have a sense of belonging, act as an extension of classrooms by allowing discussion and interaction.

Kahn's concept of ‘served and servant spaces’- segregation of toilet and stairs from classroom block.Floors raked in 'C’ shape layout enhances formal interaction thus resulting in a better learning environment and providing strong position to the teacher.

DAYLIGHT AND VENTILATION Light invited through triangular light well on the side of the rooms. Cuts off the visual and acoustical disturbances. Windows are high to get glare free light.

KEY PLAN

To facilitate interaction between students and faculty, the main academic block developed around the plaza.

The four wings faculty and administration block, library and classroom define the edge of plaza is maintained by the sparsely punctured walls.

It also acts as a transition space between classrooms.

Louis I Khan plaza space used at the time of festivals and celebrations like convocations,events,etc.

The plaza is a raised platform in the court, which is 120 feet wide serves the function of a stage on formal occassions with large gatherings.

FACULTY BLOCK

No of floors = 4 No of faculty = 90 Built up area = 7594 sq.mts Total no of rooms = 10 Corridor width: 3m Toilet= 15 sq.mts Carpet area/faculty=16.8 sq.mts Built up area/ faculty = 34.7 sq.mts Self shading of adjacent blocks on plaza CABIN LAYOUT

Faculty blocks enclose space in between them, which are developed as a raised lawns.

Openings are vertically aligned creates harmony to the design.

The arched openings in the corridors, adjacent to the staircases act as viewing galleries offering views of the landscaped courts and plaza.

Vertical wall offset projections made shaded themselves from the sunlight.

Seating placed on openings to get leisure and acts as interaction space.

VIKRAM SARABHAI LIBRARY The library is the most prominent building of the

whole campus. It is approached by a broad, imposing flight of steps from the parking lot. It is so designed as to become the centre of faculty student interaction. The library building is a five storeyed structure with a rectangular plan.

Entrance to the library is from the first floor. The design has been conceived to entail movement from the active spaces to most private and quite carrels at the farthest reaches. Library block forms focus design layout and binds various blocks and spaces together.

LEVELS

Triple height makes monumental Wide corridor pathway makes more interaction.

Library entry on rised first floor while ground floor occupy by offices.

Grand openings leads for more lighting and enough ventilation.

Seperate stack and reading section be more convinient.

In reading section, triple height ceiling makes pleasant environment for readers.

Semi circular spiral stairways makes timeless design.

Minimal use of glass in openings allows only indirect lighting.

PRE AND POST RENOVATION 1. Redesigning the interior layout for barrier-free spaces and much needed silent, quiet, and collaborative zones and to optimize and increase the usability of internal spaces for enhanced intellectual engagement.

2. Reintroducing west wing ground floor into the library space which was earlier used as an administrative office and publication department of IIMA. 3. Upgrading the lighting system required for the Library giving due respect to Kahn’s building.

4. Revamping and upgrading the existing electrical, low-voltage, plumbing, firefighting and centralized air-conditioning services.

COMPUTER LAB AUDITORIUM

KEY PLAN

Auditorium podium

GROUND FLOOR

FIRST FLOOR

There are two set of staircases in the foyer for the circulation and the two spiral staircases are located towards the rear for access to the ante rooms on the upper floor.

COMPUTER LAB

ACOUSTICS The acoustics of the auditorium are taken care of with the design of an asymmetric folded plate roof which helps in carrying the sound to the back rows without the need of any false ceiling and plaster moulds.

The computer centre is located far from the dormitories as compares to rest of the educational areas. Designed as an addition to the esisting blocks.

No of terminals - 150 working hours - 24hrs/day

The Auditorium accommodated in a combination of stepped and flat floors, which is to be mainly used for simulated conferences by participating students, lectures as well as periodic entertainment.

Ground coverage - 465 m2 no of flors - 2 total built up area - 930 m2 carpet area (single floor) - 335 m2 area/student - 1.8 m2

CONSTRUCTION DETAILS

KEY CHALLENGES OF THIS PROJECT The need to protect and enhance these buildings, since they were seriously affected by age, degree of exposure to sun, rain and wind, and problems that arose from the original construction techniques, quality of workmanship and deferred maintenance.

These have been used as a unifying element between the different formal types of buildings.

Have been used subtly in the four corners of the school building and is the main organizing principle within the school buildings, residence and staff accommodation and service.

Distinctive features of these buildings include the many square arches and brick structures on the walls with carved circles.

Facilities include wide corridors that serve as semi cubiertos transitional spaces in the complex interaction between teachers, students and visitors.

Pre and post restoration, East Façade, 2016-2018

The inadequate bearing of the terrace parapet at its base led to horizontal fractures at that location.

Analysis of the effects of the 2001 Earthquake on the buildings.

Brick has been used as a primary building material for the entire complex walls, columns. Brick arches had been used for a wide spans. Use of concrete has been restricted to foundations, floor slabs, and ties for arches openings.

The local bricks selected for construction of these buildings in the 1960s were porous. Cement mortar used was harder than the bricks. Reinforcement in concrete had been laid without adequate cover. The vertical and horizontal mild steel (MS) reinforcements in the brick walls and arches have corroded, leading to cracks in the brickwork.

The defects had also resulted in efflorescence, rising damp water seepage and brick spalling.

Façade specialized cleaning mock-ups; (left to right): before, during and after cleaning

The failure of terrace waterproofing had caused dampness in exposed concrete slabs resulting in corrosion of the reinforcement, and with inadequate concrete cover resulted in spalling.

LANDSCAPING

INFERENCES/CONCLUSION

Landscaping is an important element of design, which has been well integrated with building design in campus. The Louis Kahn Plaza is the central court around which buildings have been planned. This functions as a space for relaxation as well as for formal occasions for huge gatherings.

Faculty offices have been planned with garden courts in between two blocks. Raised lawns in front of the auditorium as well as the main entrance further aid in visually enhancing the quality of environment within a complex

Design of spaces to encourage interaction – lobbies, wide corridors etc. the Louis Kahn plaza is meeting ground for the students and staff. The planning of open spaces has been done with a system of courts. There is a absence of adequate covered pathways in the campus. The complex is not legible enough as there is absence of landmark within the complex. The institutional zones is separated from residential ares with the vast green lawns.
