Thesis 2021 | X Semester | SPA-Delhi
Introduction Even after the Phase I development of the Sabarmati riverfront, the city of Ahmedabad stays divided in two, approximately 300m apart and connected by only seven vehicular bridges. The riverfront developed on the two sides run parallel and never meet. Also it lacks presence of diversity of public spaces and activities which results in under utilization of the riverfront. Therefore it is in need of interventions to create a meaningful and complete development in the city center.
Project in a nutshell This thesis aims at developing a cultural and exhibition center on the Sabarmati riverfront and linking the east and west riverfront through a pedestrian bridge. The pedestrian bridge is envisioned to itself act as an extension of the centre and become a hub of activity, providing a sequence of zones designated for play, relaxation, shopping and gathering. The urban scale • Developing an alternate network for pedestrian mobility across the river and linking the various developments • Understanding the needs of the riverfront The architectural scale • To understand the functioning of a typical Exhibition center and its requirements. • Integrating the bridge with socio-cultural spaces to free up the riverfront banks.

01
Sabarmati Riverfront Development The stark, lifeless and characterless concrete walls run into several kilometers on both the sides of the river, which has become the defining feature of the new river front landscape. The below-mentioned are the needs of the riverfront which should be addressed through the project: •
Unrestricted access to the riverfront
•
Shaded seating spaces
•
Pedestrian connections between the two sides
•
More activity generating establishments
•
Spaces for gathering in the lower promenade
02
Rediscovering bridge as a typology of built The addition of various different layers and programs to the existing structure can enable a bridge to host various activities and dwellers in addition to having passerby. A bridge can also have markets, museums, art galleries, spaces for play and possess its own street instead of just leading to one. This does require incorpration of services, increase in the overall width of the thoroughfare to generate a new typology for a bridge having a fluid identity. This can help in redistribution of density and activity and bring meaningful development to the riverfront of ahmedabad. This requires the study of bridges both as an object and as a subject. 1. Bridge as an object: As an object the form, structural logic, material assembly, and technology needs to be studied. 2. Bridge as an subject : As a subject culture, architectural language, adjacencies and relevance to urban fabric becomes important.
03
Dynamics of existence All over the world we have various examples of the concept of multiple use of spaces where the same lends itself to various uses, thereby having multiple existences and identities. Often these examples are seen in public spaces because of their inherent attribute to afford overlapping uses. For example, Manek chowk which is in close proximity to the site is a sabzi mandi in the morning, a market during the day and food court during the nights. It is the same space but has different identities according to the time of the day a person visits it which makes its existence all the more relevant as this helps in utilizing the space to its full potential. The same can hold true for architecture as well depending on whether we treat the building as a closed static system or an open and dynamic one that is ever evolving and adapting. Space plan and Stuff are truly the two layers which can contribute to the notion of adaptability as these are temporary and can be altered with ease.

Inferences
From Case studies and case examples Seperate service bays are provided for loading/ unloading.
The height difference of the structure can be utilized to for various usage.
The exhibition hall can be transformed into facilities for a series of sports.
Linear movement on the bridge is lined up with activities.
Structural depths for larger spans require deeper members. This creates oppurtunities to create livable spaces within the structure.

Strengths
Weakness
•
Surrounded by various activity nodes which can bring a lot of footfall to the site which includes Ravivaari market, Riverfront flower park, paldi sports complex, and riverfront promenade.
•
The site has poor physical and visual relationship with both the promenade and the weekly market and acts as a seperator between the two.
•
•
Prominent location wrt to major hospital, institutions and residential development being in the vicinity.
The site is too linear wrt the program of exhibition halls as the required dimension along with setback leaves very less room to accomadate all the services, site circulation and movements and the landscaping.

In 1870, Ahmedabad attained the status of municipality. As the city witnessed unprecedented population growth in 1921 and 1931, the municipality formulated four Town Planning schemes (TPS)9 in accordance with the Bombay Town Planning Act 1915. One of them, the Ellis bridge development scheme, located on the western side of the Sabarmati, opened up a new phase of urban expansion in the form of cooperative housing societies. The first housing

•
Absence of any other pedestrian friendly bridges connecting the two sides of promenade, makes it one of a kind destination not only for locals but also tourists.
Lack of accessibility and poor relationship between the nearby activity nodes and site.
•
Occasional flooding tends to limit the development of activity generators on the lower promenade.

Micro-climate Sabarmati River flowing through the city center. On the right bank of the river, i.e., towards the Eastern part of the city an average dip of about 1.56 C and 1.59 C has been observed during summer within 200 m and 300 m. Also, the temperature falls by about 1.61 C from the bank up to 200 m and 1.82 C from the bank up to 300 m during winter.

Site Analysis

Site Potential
Visibility The design has great visibility from the riverfront flowerpark, the promenade and two major bridges namely Sardar and Ellis bridge. Whereas it stays hidden from the majority of development on east side due to presence of fortwall. Also, there is a very weak physical connection and non existing visual connection between the riverfront promenade and the development of the surroundings.
Edges The riverfront road on the east is the only vehicular access road leading to the site. The riverfront edge needs to be carefully designed as it is prime visibility and has potential for pedestrian access from and to the riverfront promenade. Where the pedestrian bridge meets the site is a potential activity node.
Climate Data Ahmedabad experiences a semi-arid hot climate. The weather and climate in Ahmedabad is largely influenced by the Arabian Sea. The average temperature of the city ranges in between 12 degrees to 41 degree Celsius. The prominent Wind Direction is from West and South-west during summers.

1. Exhibition Hall Configuration
2. Determinants for zoning
3. Determinants for circulation
Connected Foyer: Allows for views on one side, halls spaces are more flexible for space allocation and provides all weather access.
Zoning needs to be done so as to segragrate the busy exhibition center from the public greens and the bridge such that they can exist in harmony together instead of restricting each others activity. The major built on the plot was pooled together such that a bigger public greens can be developed which can open up to the river.
The circulation for the movement across the riverfront needs to be designed as such to link the various activity zones nearby such that all the facilities become connected. These include the Exhibition center (part of thesis), Ravivaari market, event center, Flower park and the lower promenade walkway.
9m Clear
9m clear span is the minimum requirement which is followed by most of air conditioned facilities to reduce the overall volume of the space and also accomodate indoor play activities.

Segmentation
Pros
Pros
Pros
1. Halls arranged on either sides with the central plaza connecting to the bridge. The central circulation leads from the plaza and the halls are entered from entries located parallel to the riverfront.
1. The idea of halls arranged on either sides with the central plaza connecting to the bridge and no basement is retained.
1. Halls arranged on either sides with the central plaza connecting to the bridge through the art gallery and auditorium.
2. The main road slopes up to create a drop off at Level 1.
2. Easy visitor movement at the upper level with food court and parking at the plinth level.
2. Parking accomodated in the plinth, no basement needed. 3. Loading/Unloading happens at the plinth.
3. Floating type segmented bridge is used at the lower promenade level to create a unique experience.
Cons
Cons
Cons
1. Loading/Unloading for heavier exhibits is a problem.
1. Bridge still appears to be a seperate entity and flooding may damage the components.
1. Art gallery restricts entry and exit from the bridge to and from the halls.
2. Movement issues involved with taking the users to level 1 for access. 3. Bridge appears to be a seperate entity and lacks shaded spaces.
2. The riverfront RCC walls stay, still segregating the lower promenade and the various destinations nearby from public and visitors.
4. The connection between the central plaza and the bridge seems forced having no significance to each other.
3. Lack of open space and safety concerns not addressed.
2. Lack of open spaces for exhibition and leisure. 3. Bridge lacks accesibility from exhibition halls and shaded spaces. Its design is devoid of the character of amdavad.

The Final Iteration
Pros
Pros
Pros
1. Halls arranged on either sides with the convention hall extending to form the bridge with art gallery being located there. Bridge starts becoming part of the design.
1. The exhibition halls are at the ground level with convention hall being raised up such that it sits on top of the bridge with art gallery being located there.
1. Halls arranged together which helps in easier and secure access to the facility.
2. The cental plaza turned into poblic green stepping down and opening up to the lower promenade and the reiverfront starts becoming more open and public.
2. The bridge is a single story structure using pratt truss, inspiration for which is taken from the Ellis Bridge (the first bridge of amdavad). 3. The bridge extends via the underpass connecting to the Ravivari Market at the lower level across the road.
2. Food court is provided in the open terrace for huge gatherings and celebrations. 3. Large open space provided and bridge has unrestricted access for all. 4. All the spaces on the bridge are well shaded and protected.
Cons
Cons
5. Direct connection from the riverfront market.
1. Structural complications due to curved plan requires more supports for the bridge.
1. The space below the convention hall has insufficient height and is full of columns which results having an experience of being in a parking.
6. Gallery present at the upper level providing a level of privacy for the function, with lower level being open to market hustle bustle.
2. Lack of shaded spaces on the bridge.
2. It lacks open green spaces and has issues of access control of the halls, the food court, the public greens and the bridge.
7. Floating walkway introduced for those seeking adventure leading to the water sport deck.
3. Views are hindered and activity space is limited due to the form of the bridge.

Re-iterating the realtionship between the bridge and the exhibition halls lead to an understanding that it is important for both to have their own seperate identities as much as that of a collective whole. Therefore, the public green is the link at the ground level whereas art gallery at the upper.
the two masses together to 04 Anchoring make a whole. Introducing art gallery at second level of the bridge, away from hustle bustle and noises yet still near all the activity.

2. Massing and bridge orientation
3. Edge conditions
The main aim is to give back the riverfront to the city. To do this the exhibition halls are clustered together so that a consolidated green can be provided where the bridge makes landfall. Now for mutual visibility retail and food outlets should be on one side keeping the activity area open towards the edge visible from exhibition center.
The bridge is oriented such that it steers clear of the main massing at road level such that there is a mutual visibility between the activities happening. The exhibition center massing splits in two to give view to the river and break the monotony of a long continuous facade. The bridge links the various activity hubs all around to generate movement along and over the river.
The various edge conditions vary from being free public access to public controlled access. The greens open at road level on one side and to the riverfront on the other. The main access and service edge lies along the access road.

Structure: The Bridge
The Bridge: Pratt truss was used in the construction of Ellis bridge, which was the first bridge to be built in ahmedabad. Therefore, taking inspiration from that, the main bridge structure is also a pratt truss with spaces built within. When used in bridges pratt truss can be used to span as much as 80m-100m depending on the depth of the truss. For the design a span of 60m and a depth of 12m is taken which results in the structure being able to accomodate two levels for different activities. Structural Grid and material(Pier): RCC at a distance of 60m c/c Width of the structure: 14000mm + 3000mm (Cantilevered walkway)

Exhibition center: The structural system adopted for the exhibition hall is a composite structure which is majorly a RCC framed construction which incorporates Steel Pratt truss for large span roof of the main halls. The truss is suitable for main exhibition halls having a span varying from 20-50m with column being spaced at a distance of 6m-9m. Therefore, a structural grid of 8.5x8.5m is taken to incorporate the roof and the parking with the main exhibition halls having a clear span of 40m.
