VOCATIONAL HUB - RATHNAPURA

BSc - Year 03 - CDP PROJECT

In this project we have to design a Livelihood center, which is a Vocational hub. Rathnapura has been famous for gem mining & gem trading since ancient times. With the time, the gem industry in Rathnapura has changed and developed with the transition from traditional practices to modern practices. It is required to understand and facilitate what is available at the current context and what is needed to be there to uplift the gem industry in Rathnapura. This proposed vocational training center will help them to improve their skills for upliftment the gem industry in Rathnapura.

DESIGN AMBITION

“Gem Promotion through Vocational Hub”

Rathnapura is a Gem based cultured city. The Amba gaha yata market is in the micro context of this site. So, it acts as the heart of the Gem trading of Ratnapura That means the amba gaha yata market takes a special place than the Rathnapura area. There’s a high demand for this amba gaha yata because there’s an industry in there

But that industry doesn’t function at the present time. There’s something running from inside but the people aren’t aware of its value and its potential. Even though there’s an industry, there’s no attraction towards it. As I mentioned in my design ambition, the reasons for this are the technology human skill, ICT and fields like organization. The reason for this scattering is that there’s no proper market place in this area. That means a Hub has to come into this place as a solution That hub has to be a place where it can get the attraction of the general public and to show the potential of this node.

“TOGETHER TOWARD SUCCESS”

DESIGN DEVELOPMENT

RCC Cocrete

In this design for the substructure and superstructure, Slabs, beams and columns, rcc concrete is used. It is the main element used for these. Reason for choosing this element is that it can be easily recycled and could use again. By that construction waste can be reduced. When recycling and re using these concrete, it helps to protect natural material sources.

When creating these CSEB bricks it is done by using a block and soil is highly compressed under high pressure. When using CSEB bricks for walls, it helps to maintain good thermal comfort for this building because when these bricks are making soil is used as a major material

Exposed Bricks

Exposed bricks are used here for the circular walls in the center of the building. By using exposed bricks, it helps to create solid void pattern to the wall and it helps to get good light and ventilation to the building. And also, the natural colors and textures of these bricks brings a unique character to this space.

Terracotta tiles can be used for both indoor and outdoor spaces In this design these tiles are used for corridor floors. These terracotta tiles brings a rustic look for the space. These terracotta tiles are much stronger and the durability of them are high.

Steel is mainly used to construct the structure of the geodesic dome. Since double glazed glass is used in the triangular dome’s structure, it is essential to have a material like steel to bare the load The design is spread over a wider area and steel was used to create the structure of the building. Steel is mainly used in this scenario because of its high durability and strength.

Timber is readily available and it’s an economically competitive material In this building, Kumbuk Timber is being used for adjustable louver window frames and all the doors. Since timber is a sustainable, ecological and a renewable material, it gives a lot of environmental benefits. Due to the natural colour of timber it gives an aesthetically good look

Terracotta Tiles Steel Timber Double Glazed Glass

In this design double glazed glass is being used to the adjustable louver windows and for the triangular dome structure on top of the center space of the building. The double glazed glass is used for the louver windows because the air gap between the glasses acts as a noise barrier. Due to this it has been able to reduce the noise of the vehicles that moves on the roads along the side of the site.

HOUSING PROJECT- COLOMBO 10

MSC – FIRST YEAR – 1ST PROJECT

In this project we have to housing neighborhood. Housing is a basic need for humans. family life & relationship are fostered bonds between family members at home while the communities are based on the housing neighborhoods. The objective here is to design a housing neighborhood for people for certain economic class in a given site in Wanathamulla, Colombo 10. The total project will cater 200 housing units and commercial activities.

PROJECT BACKGROUND

JUSTIFICATION

SITE ANALYSIS

Many of the housing projects introduced by previous governments before the lower income category have been provided with housing after a certain amount of valuation. There the value of those houses had to be paid in installments. If such a lower income project is carried out on such a valuable land, the value of that land will also be added to the houses being built here. What happens there is that the problems of those lower income people get worse. There they start making money even though they are doing various anti social work. What is happening is that the housing schemes designed to uplift the living standards of the poor and uplift the living standards of the people are further degrading their living standards

There I considered who really needed this housing scheme What I found there were more than 20 government agencies located within 5km of the site. Overall, the majority of these public servants belong to the professional category. 30% as a percentage. 20% of it belongs to the western province. 9% of them have permanent housing in Colombo. The remaining 11 percent may be temporarily residing in Colombo. Or some may come from homes in their outlying areas. Either way, it is a waste of money and time for those public servants.

As a result, they become mentally and physically unhealthy. So, all they have to do is build houses so that they can easily go to their place of work.

• Project name Community Housing

• Location Wanathamulla, Colombo 10

• Client Government

• User Middle income government officers

CONCEPT

In the middle class most of the times both mother & father are breadwinners. Which results them both with busy lives and less chance to interact with each other. It also increases stress An environment that is stress free & allow the busy people to interact more. Views and environment related gathering places are provided in order to calm their minds which will allow them to interact more & Strengthen their bonds.

AMBITION

According to the user category of this design, one of the design problems that I found to be related was the declining mental level of the people. The main purpose of this design was to find a solution to that problem. This is designed so that views are not blocked to solve the problem. The use of louvered swing windows allows for better ventilation inside each unit through cross ventilation, and the windows and light well are designed to allow light to enter each individual unit. Therefore, a good thermal comfort is created inside the building. There, the use of such environmental strategies raises the mental state of the people and thereby improves the quality of life.

RESOLUTION OF BUILDING SERVICES

Water supply Water from the Drainage Board is used to meet the water requirement. The water coming from the road through the pipes is stored in a sump and the pressure pump is used to carry the water collected in the sump to the overhead tank at the top of the building. The water is distributed to all the units through pipes passing through the overhead tank.

Waste water recycling Due to this design, a large area of land is allocated to the landscape area and a large amount of water is required to maintain it. There, this wastewater management is an important aspect that needs to be looked at critically. If this wastewater is used for maintenance without treatment it can be harmful to living organisms in the land. Therefore, the wastewater should be transmitted through anaerobic filters for treatment and then discharged into the environment.

Roof drainage & rain water harvesting- Here a rainwater harvesting system can be used to collect and store rainwater and reuse it. In this design, the collected rain water can be used for supply water to plant tuff and the toilet flushing system. The water collected on the roof of the apartment complex is piped to an underground tank below. The water in the sump is then pumped through a pipe to the units on each floor.

Waste management The collection of organic waste and solid waste is done through the Colombo Municipal Council There are common spaces in this design where the organic waste & solid waste are placed in the garbage chutes installed near the lift lobby so that they go through the pipe of the garbage chutes into a room on the ground floor. The location is easily accessible to the municipal council vehicle.

Energy supply – The basic electricity requirement is provided by the Electricity Board. The solar panel on the roof of the housing complex also supplies electricity to the housing complex.

AMBITION

When constructing a building in such an urban environment where the natural environment is severely affected, the damage to the environment should be minimized as much as possible. Also, the structure should be designed to be easy to build and durable. Therefore, when considering the structure, it should be constructed to suit the context.

TYPICAL SECOND FLOOR

TYTPICAL FIRST FLOOR

TYPICAL GROUND FLOOR

Substructure - The substructure is the lowest part of the building that transmits the entire weight of the building. Here the nature of the soil and the bearing capacity of the soil should be taken into consideration while selecting the substructure There pile foundation and raft foundation were used for the substructure of this design. This structure was used as a remedy because the t18 / t20 ‘watta’(slums) near the site was submerged in water and it was assumed that the soil moisture was high. However, the pile / raft foundation used that structure due to its high load bearing capacity

Super structure - Basically the super structure consists of a 300 * 300 column base structure. Also, the floor of this structure is made of rcc concrete, and all the walls here are made of compressed stabilized bricks. Its windows and doors are made mainly of materials such as steel and timber.

AMBITION

The aim was to provide a natural healing effect to the occupants of the home, while preserving their privacy and giving them a greater view of the environment.

This avoids direct sunlight and direct wind flow. Also, the vines around the vertical blind give the viewers a natural healing effect.

1000mm high half wall around the cantilevered balcony protects the viewers privacy and allows viewers to view maximum views. Also, the flower trough around the balcony tries to bring naturalness into the house.

(C) Aluminum Swing Window

The aluminum swing window consist with double glazed glass. So, it prevents the heat come into house. it only allows light enter to the house.

Lastly there is a 225mm thick wall coated with weather shield paint to protect it from the rain.

HERITAGE & CONSERVATION PROJECT- ANURADHAPURA

MSC – FIRST YEAR –2ND PROJECT

This study focuses on the conservation and restoration of the ancient city of Anuradhapura, a Heritage site of architectural and Archaeological value, as well as its sustainability. The preliminary study of the project focuses on the Archaeological and architectural heritage of the "Isurumuniya and Ranmasu Uyana" located within the ancient city limits of Anuradhapura. The main objective of the project is to present a hypothetical strategy for an architectural design solution as an effective archaeological heritage conservation project combining building ruins and landscapes.

PROJECT BACKGROUND

Project name – Heritage & Conservation

Location Anuradhapura

Client Archeology Department

User Locals & Foreigners

ANALYSIS

PROBLEM IDENTIFICATION

Tourists visiting Anuradhapura are restricted to visiting the Ranmasu Uyana. The main reason for this is that this place does not have a proper understanding and guidance. This is a key factor in interpreting it simply as a place used for bathing by ancient kings. This is mainly due to the lack of a clear understanding of the Ranmasu Uyana and its use of technology in landscaping and architecture in landscaping gardens in Sri Lanka. There is no guide to properly identify the archaeological value here and its uses.

Another factor is the lack of a proper access road to the Ranmasu Uyana. Ranmasu Uyana is located in the northern part of Isurumuniya. The park can be reached by a small road that falls into the Isurumuniya car park area over the Tissawewa bund. However, due to the difficulties encountered on the road and the small space available at the entrance, the number of tourists visiting the Ranmasu Uyana is less. This is one of the reasons why tourists do not pay attention to this ancient land of ancient value. Created with a high level of understanding of the use of technology after Sigiriya, this goldfish garden has begun to gradually depreciate due to improper conservation and failure to preserve its antiquity.

JUSTIFICATION

This Journey starts in awareness center built at the starting point of the entrance to the Ranmasu Uyana. There, people can be given a basic understanding of the place.

Stones were primarily used for the construction during the Anuradhapura period. It was necessary to show the glory of Anuradhapura stone technology even with this design. This type of box shaped design was made to show the solid quality of the stones. The building is located at the beginning of a staircase that can be climbed up The stairs are designed to arouse the curiosity of the visitors as well as to create a sense of enlightenment in their minds. A staircase is used in the design of places of worship such as Mihintale as it is a factor that evokes the concentration of the mind of the visitor and directs the mind towards the design and has been used in the design of the staircase in this building At the end of the upper staircase is a brick facade It highlights the ruins of the East, and was built on a ruined part that is not present in the ruins of the East. This design was able to highlight the architectural essence of the Ranmasu Uyana. Also, the main areas within this awareness center are the presentation area / ticket counter and souvenir shop.

Then take people to places with these ruins in the form of a journey.

JUSTIFICATION

Also need to create a leisure pavilion for people to relax during this journey. There they have to touch the ground of this ancient significance and build that experience so that the feeling can take over. The reason for this is that there is no opportunity to reach the ruins while traveling on the deck. There is no opportunity to get down from the deck. That is to say, this place allows Them to experience the knowledge gained through the entire tour with Their touch. Here the total cost of making this design can be found by charging a visitor fee from such visitors once people start to be attracted to this place.
