INTRODUCTION TO TOPIC • The Borivali station is a terminus for slow, semi-fast and fast trains on Mumbai Suburban Railway System.

• It also serves as the final city limit station for all mails and express trains on Western Railway before leaving Mumbai. The station caters to 2.99 lakhs passengers daily and is the busiest station on the western line.

• Borivali railway station is up for redevelopment under the Ministry of railway’s policy of redevelopment of railway stations across the country.

• The station will be redeveloped into a state-of-the-art multi-modal transit hub which will include rail transport, bus transport connected with cab, auto-rickshaw services and personal vehicles along with a commercial office complex.

BENEFITS OF MIXED USE T.O.D • Promoting higher densities and the concentration of jobs within relatively small areas, transit oriented development creates agglomeration effects proven to boost a city’s competitiveness.

• This concentration creates vibrant communities with high-quality public areas and shorter commuting distances—making cities more livable.

• By concentrating jobs, services, and housing within the catchment area of transit stations, TOD makes public transport a more attractive and efficient option, while reducing dependence on private cars and promoting shorter commutes.

As a result, TOD typically translates into higher productivity and a smaller carbon Footprint.

FOUNDATION- PILE FOUNDATION Pile foundations are deep foundations. They are formed by long, slender, columnar elements typically made from steel or reinforced concrete, or sometimes timber. A foundation is described as 'piled' when its depth is more than three times its breadth.

LOCATION ON SITE

• Depth of the piles will depend upon the soil conditions, if considered medium clay then piles up to 45m approx.

WARREN TRUSS • The Warren truss consists of longitudinal members joined only by angled cross-members, forming alternately inverted Equilateral triangle-shaped spaces along its length. This gives a pure truss: each individual strut, beam, or tie is only subject to tension or compression forces, there are no bending or torsional forces on them.

• Loads on the diagonals alternate between compression and tension (approaching the center), with no vertical elements, while elements near the center must support both tension and compression in response to live loads. This configuration combines strength with economy of materials and can therefore be relatively light.

Roof covering material- Galvalume sheets • Galvalume is a roofing sheet that has a coating of zinc, silicon, and aluminum.

• All these coatings protect the metal and are the primary form of the steel made of oxidation.

• It protects the base metal and sacrificial metal coating • The thicknesses of the Galvalume are approx. 1 mil thick.

Stack effect or chimney effect is a phenomenon that occurs because of the natural heat transfer. The warm air has a lower density rather than the cold air and raises to the upper part of the building

Skylight material- polycarbonate sheet Polycarbonate is a thermoplastic that comes in a transparent sheet. It is incredibly tough and absorbs minimal moisture, making it resistant to impact damage as well as water damage. It's also flame-retardant and chemical resistant.

TRACK DRAINAGE SYSTEMS • Surface drainage: Surface water due to rain or snow, or from adjacent areas should be drained off properly by designing well-planned and effective surface drains.

• Sub-surface drainage : In case water percolates into the formation due to bad soil or such other reasons, the formation gets adversely affected and this has a bearing on the safety and stability of the track.

1 Drainage in Mid-sections Between Railway Stations

2 Drainage in Station Yards

3 Drainage of Station Platforms Slopes away from track Normally, all end platforms should be sloped away from the track.

Discharge on non-track side All drains from platform shelters, tea stalls, toilets, water taps, etc., should be enclosed in pipes and should normally discharge or release their contents on the non-track side of the platform. Covered longitudinal drains should be provided on the platform, if necessary.

Discharge not towards run-through lines In the case of island platforms, all drains should discharge their contents on the less important side of the track and not towards run-through lines.

SOLAR NET-METERING Net metering (also known as net energy metering or NEM) is a solar incentive that allows you to store energy in the electric grid. When your solar panels produce more electricity than you need, that energy is sent to the grid in exchange for credits. Then, at night or other times when your solar panels are underproducing, you pull energy from the grid and use these credits to offset the costs of that energy.

SOLAR CALCULATIONS: Watts per panel x hours of sunlight received x .75 = daily watt hours Considering watts per solar panel= 250 watts Hours of sunlight received in Borivali= 10 hours 250 x 10 x 0.75= 1875 daily watt hours to convert to KWH divide by 1000 =1875/1000 =1.875 kwh/solar panel According to the roof area available to install solar panels, 300 solar panels will be installed Therefore, total energy generated, =1.875 x 300 = 562.5 KHW

FIRE FIGHTING SYSTEM All wet-riser pipes remain charged with water at systems pressure. The opening of a hydrant landing valve or hose reel on any floor reduces the pressure in the pipeline and starts the hydrant pump. Pump-sets of suitable capacity are provided for this purpose. Because of the static pressure differential caused by the change in floor height, a multi-stage pump is employed so that different tapping can be taken from the output of the pump. Each of these tapping can be used to serve more than one floor.

Pumps-sets should be fed with reliable electric supply from a separate feeder and it is therefore also desirable to have a stand-by diesel pump.

HVAC SYSTEM FOR COMMERCIAL BUILDING Central air conditioning (or central A/C) is a system in which air is cooled at a central location and distributed to and from rooms by one or more fans and ductwork. The work of the air conditioner compressor is what makes the whole process of air conditioning possible. The compression of the refrigerant gas enables it to discharge heat out of the house, which is how the cool air is created.

CENTRAL SYSTEM ICE STORAGE AIR CONDITIONING At night, water freezes and energy in the form of ice is stored.

During the day, low energy pump is used to transport the AC coolant through the ice to produce cool air.

This allows the energy intensive traditional AC compressor to be shut off to minimize power consumption.

The chilled air is then distributed through the HVAC system.

Sub systems of centralized AC: A central AC’s main components are: •Fans that pull air through the system •Evaporator coils that change refrigerant from liquid to gas •A compressor that pressurizes refrigerant gas •Condenser coils that turn refrigerant gas into a liquid •Refrigerant lines that carry refrigerant between the coils •An expansion device that regulates refrigerant flowing to the evaporator

PERMEABLE PAVERS Permeable paving systems are porous, so they allow water to infiltrate the pavement and drain into the ground or sub-base rock underneath. These paving systems are just as strong and durable as traditional paving materials such as concrete, asphalt, or compacted gravel. Several types of porous paving grids exist, including plastic grid pavers with flexible joints; rigid or rolled plastic pavers; interlocking concrete grids; and permeable concrete and asphalt pavement.

The permeable pavers have open cells that are filled with gravel or grass and are designed to let water enter into their surfaces, get detained in the rock base, and absorb into the ground beneath. Paving systems that use hardscape surfaces (concrete, asphalt, or compacted gravel) will collect stormwater, causing it to pool or run off. Instead, permeable pavers have a porous surface that naturally mimics and recreates the way the ground reacts to rainwater. The rate at which the water drains into the surface depends on the specific type of permeable paving system used.

Permeable pavements aid stormwater management, reduce runoff, and decrease flooding risks. Conventional concrete, asphalt, and gravel-only pavement are the primary generators of stormwater runoff. Runoff is dangerous for cities, as the water collects contaminants and gets hotter as it rolls through streets. Eventually, this runoff will flow into and disrupt the natural waterways

WATERLESS URINALS

Daily water saved calculations: Railway station: Footfall: 19,000

Number of men: 9,500 Urinal requirement according NBC: 4 urinals for first 1000 passengers and 1 after that for every 1000 passengers.

Total urinals required: 13 Flush capacity per urinal: 10 liters

Approx. frequency of urinal usage per day= 5000 men Therefore water required for flushing urinals per day= 13 x 10 x 5000 = 6,50,000 liters per day 6,50,000 liters of water will be saved by using waterless urinals at railway station.

Office building: Daily footfall: 4200 In order to limit liquid waste and save water, traditional toilets for man are replaced by waterless urinals in schools, offices, libraries, public transportation and stadiums. Those require lower setting fees and service security. The principle is used a slight piece of liquid which undergo waste from human but avoid the smell. As a result, the amount of water for flushing toilets is reduced, also save money paid for electric bills and keeps the toilets clean which is a necessity at Indian railway station toilets

ARCHITECTURAL REPRESENTATION AND DETAILING

SERVICES

Number of men: 2100 According to nbc: over 200 people add urinals at 2.5% 2.5% of 2100= 53 urinals.

Approx. usage of urinals per day: 1500 times Water required per day for urinals= 53 x 10 x 1500 = 795000 liters

Therefore, 7,95,000 liters of water will be saved in the office building by using waterless urinals.
