Engineered Bamboo: An Alternative Urban Material of Construction_Design Dissertation_2020-21 by aoa_confluence_2022

: An Alternative Urban Material of Construction

| Academy of Architecture Guided by: Prof Ar. Rohit Shinkre

The very first question that arises is “what are urban materials of construction?” to which the answer is materials which have contributed to the construction industry to create an ideology of permanence and stability amongst other materials. The major urban materials of construction are concrete, steel, and glass. Initially these materials were used in an attempt to transform architecture from a horizontal plane to a vertical plane. But today these materials are used as confirmatory stamps of the definition of urban given to any area. They are simply included in the process of picking and putting.

With just four years of harvesting age, when compared to other renewable and non renewable materials of construction, it is the fastest growing raw material the world has.

The 1st imagery of structures made in Bamboo are generally whole culm bamboo used in Bali or other parts of the world. Even though Bamboo is used as a construction material, it is almost impossible to introduce it as a main stream material of construction due to its vegetal nature of built. It is difficult to standardize the material due to unique defects in each element which are categorized as following

Engineered bamboo - Bamboo, which is treated, processed and standardized for construction. The idea of Engineered Bamboo is very similar to wood as Bamboo is split, flattened, compressed and provided with a particular cross section like engineered wood. The visual appearance of both are extremely identical in nature. The products are also similar to those of wood, such as glued laminated lumber, glulam cross laminated timber or CLT, which are wellestablished industrial products used in construction, mostly in industrialized countries.

A Step towards space making

• • •

•

An interconnected system of beams and columns. A good fit with building programs that require larger and more flexible interior spaces. Provides the opportunity for larger areas of glazing than panelized systems. Requires additional measures, such as cross bracing and shear walls, to address seismic forces and other lateral stability issues

•

Similar to Post + Beam, except beams have been replaced by panels that can span on their own and do not need to rest on a beam. Panels are either solid or prefabricated elements made up of multiple parts. Panels typically rest on columns on each corner.

•

Vertical and horizontal loads are carried by solid wood or prefabricated panel elements arranged in two directions in plan. Tend to result in spaces with limited flexibility for reconfiguration over the life of the building and therefore are better-suited to programs where occupant needs are fixed, such as multi-family residential.

• •

•

Vertical and horizontal loads are carried by solid wood prefabricated units stacked one on top of the other. Modules are often installed with furnishings included, all done beforehand at the factory Best-suited to programs involving repeated cellular units, such as hotels, student dorms, or temporary housing. A module is a recurring basic unit. Prefabricated ceiling or wall elements are often referred to as "modules" in timber construction. This category is therefore called "roommodular" as opposed to simply "modular"1.

• •

The structural system is developed using digital and parametric design and fabrication tools. The high machinability, precise prefabrication abilities, and favorable strength-to-weight ratio of wood make it a suitable material for these special structures. These projects tend to involve extensive research and development periods. Many of these structures are one of-akind and expensive, and are demonstrations of feats in design, structure, and construction rather than replicable projects

To Construct with the Engineered Bamboo, a set of parameters while designing can be utilized. By identifying which system can be used in which area, the type of construction built can be changed and developed into permutation and combination of set elements. The 4 elements are 1. Post 2. Massive Panels ( 1 way Span) 3. Prefabricated Hollow Panels 4. Massive Panels ( 2 way Span) The combination of vertical and horizontal can be applied with different area which will allow for economic feasibility and technical feasibility in the whole project. The whole structure can be understood as a kit of parts which will allow for getting a set of particular members for construction.

The approach which has been adopted to have a site is one where current to provide for an of constructing a building on site . The idea is to in an area where the has a of concrete and steel and the site having difficulties regarding constructing with the materials already in use. The is to locate a site where construction of concrete is really difficult due to lack of proper access and construction of Steel is extremely heavy as a solution. These sites generally act as to .

1. : The site needs to have an Urban context with structures built with concrete and steel in an attempt to substitute the material as an intervention 2. : The site needs to have a lack of connectivity to the Ancillary road due to which concrete and steel construction is not a viable solution to the redevelopment of such projects. 3. The site needs to be in a dense network of an urban setting with a diverse group of communities and programs around 4. : The scale of the project should be relatable to its surroundings and context in an attempt to have a comparative analysis.

The area of concern has a indirect impact on the Locality as they are parts of a different identity yet serve a buffer between multiple localities which are affected due to any changes in and around the localities. It provides for the extents of till where the impact of the intervention will be prevailing and hence stating that the locality has a wider role to play with respect to the area of concern.

The Area under delineation is chosen after rigorous elimination of area of concern with the fact keeping in mind that each and every nodes of the locality need to always provide an identity to the whole and should always be easily accessible • The North end is carefully delineated with the Navjeevan Crossroads edge Buildings above them don't provide value to the locality. • The South end has the H.N. Hospital, on of the major and famous landmarks in and around the locality. • The East Side has the start of Khetwadi and Bori Bazaar area creating a new personal identity to their locality. • Finally the West area has the Ferry Bridge, Police Station and the Grantroad station as the landmark for end of the locality.

This maps showcases different degrees of road network hierarchy. Primary roads have maximum amount of vehicles passing which line up to both x and y axes. The secondary roads connect the primary roads and the tertiary roads. The tertiary roads allow minimum vehicular movement while maximum user and pedestrian movement to access the site.

Primary and secondary roads have trees lined up parallel to its length while the tertiary roads lead to plots having natural elements in them. Major open spaces are less in this locality and hence a potential requirement. People need to travel to another locality to enjoy quality of an open and green space. 1. Gilder Tank 2. Panalal terrace 3. Navjeevan Garden

Figure ground map is generated to give an essence of how sparse is the built vs the unbuilt and if the built have enough open spaces around it. As one can see by the map the selected locality is densely packed with structures having almost zero to minimum amount of distance between them.

This map showcases DP of the locality which highlights the fact of the locality being in an urban centric residential area with multiple social amenities already present within the neighborhood. The selected plot is a perfect spot for residential units

Grantroad is an old part of South Mumbai which has been thriving with multiple small businesses and majorly filled with mixed used low rise high density structures. Today it is a mixture of old and new architecture, along with layers of history showcased in the facades and the rich community of people. The area caters to various types of commerce.

There are 2 major ancillary roads to which the structures are generally face towards. Even though most structures have direct access to the road, there are multiple structures to have almost negligible access to the road except for pedestrian movement. The precinct is filled with narrow streets and dense fabric of people. These small areas are extremely difficult to be reconstructed with the help of Concrete or Steel due to lack of connectivity with the Ancillary road.

Most of the structures are old residential buildings the potential development could be re development of the structures.

The sun path is divided into Summer Sun and Winter Sun. The sun majorly moves from East to West via South. This allows the North side facade to receive light without and incident direct solar radiation. All sides are generally shaded with structures abutting the site. The south side needs to be shaded with appropriate shading device.

The site has a small access road of 4.5m which abuts a 30.5 m main road. Pedestrian movement is prevalent with constant movement of bikes and bicycles across the galli.

There are no trees present on selected site. Vegetation around is comparatively less with respect to the tree cover and open spaces. Trees need to be planted for shade and vegetation increase.

The wind flow is majorly in the directions West, South West and North North East. All these directions needs to be taken into consideration.

The site is a small plot besides a narrow street (M.P. Agiary lane) which is adjacent to MS Ali Road which is the ancillary road of the locality. The lane is a 3m wide lane with only pedestrian movement and no vehicular movement at all. The mansion is a G+1 structure which allows for a residential and a commercial component. In front of the structure along the street there are multiple such commercial components on the ground floor and residential components on the 1st floor adjoining the same.

These people are the ones who will consume the space periodically. With different demands of the users, the spaces are changed and adapted to. The decision of the space is majorly in the hands of this group.

These people are the ones who will take over the commercial department on the ground floor of the structures. Spaces with respect to their needs will be developed as per the wills of the User.

The owner dictates the allowance of any user in the structure. He / She is responsible for the structural system of the structure and if any changes needs to be done with respect to the policy of Residential and commercial spaces is majorly done by the owner.
