Lessons for flood

Recent flood in Sangli and Kolhapoor is leading to disastrous outcomes in terms of living things and wealth . We can not challenge the power of mother earth , but we can learn from our mistakes and can take precautionary measures to avoid the possible damages . Here are the basic 5 things in terms of personal property development or purchase to consider to avoid damages in case there is a floor like situation  : 

1: Check the Blue line and Red line If the property you are looking to develop or purchase false within 50 to 100 m from the river or any water body always check the level of Blue line and red line marked by the Irrigation department of Govt. of Maharashtra. You can easily get the maps from irrigation departments website. 

2 . No Construction beyond blue line :   Blue line is the average level of flood within past 25 years . This is a restricted zone . You can not construct or undertake any type of construction beyond blue line . However this space can be used as playground , gardens or seasonal farming . Do not purchase any bungalow plot , flat if the building is beyond blue line. 

3 : Restricted construction between red line and blue line. Red line is the average level of high flood within past 100 years .This is the highest level of water level achieved during high flood . This is a restricted zone of development . If you are planning to purchase a property which false between red line and blue line , the ground floor of the property should be above the level of red line. You should avoid basements in this zone. 

4: Always take a plinth Plinth is a necessary part of any construction .  Always take a plinth level of 1'6" to 2 ' above existing ground level irrespective of any zone . 

5. Always consult an Architect and structural engineer : 

If you are planning to develop a property which is beyond red line, consult as Architect , he or she can help you to survey the water levels and finalize the floor level. Normal footings and generally avoided near river beds , instead of directly dealing with a local civil contractor it is better to hire a structural engineer who can study the existing soil conditions and design a suitable footings and structure above for you. 

Fast Dry wall Construction

In India , Dry wall construction Practice is taking shape ,  though it is limited to internal spaces  , people prefer dry walls because it increases the construction speed and carpet area of the room .

Instead of 6" thick brickwork , which becomes 9" after both side plaster , we can use a 3" dry wall , which can take care of conducting or concealed plumbing also.

These Dry wall are equally fire resistant , sound proof  to conventional brickwork  but lighter in weight .  best part is we can reuse these walls if installed and uninstalled carefully. 

Each panel width is 600 mm , and height varies from 1800mm to 3000mm . We can choose any panel height to reduce the wastage . 

Bottom and Top of the panels are fixed to floor and ceiling with aluminium channels . If to be used for the floor or roof , a regular support @ 600 mm centre to centre is needed. We can use these panels for slopping roofs also with MS framing.  

#Aerocon #Drywall #Prefab 

due to these advantages these panels are used for Mezzanine floors , on in Prefab structures or for Boundary walls . 

Rates for 2" or 50mm dry wall starts from Rs.135/- per sq.ft.

Rates for 3" or 75mm dry wall starts from Rs.155/- per sq.ft.

 

Assocham Summits Infrastructure Growth Roadmap to Finance Minister

Domestic infrastructure companies should be allowed to list in overseas capital markets through direct equity shares in a bit to spur growth, industry body Assocham has suggested to the government. “Listed and unlisted domestic infrastructure companies be allowed to list in overseas capital markets through direct equity shares as companies once listed abroad have better access to low cost funds and simultaneously they may also be allowed to set up an entity abroad to raise equity and invest the same in India, “it said in a letter to Finance Minister.

             Also, the transfer of holding to such an overseas entity from an Indian entity should be permitted at erstwhile book value, prevalent till March 31, 2010 as infrastructure projects are long-term and require high gestation, it said. Assocham president, Rajkumar Dhoot said, “Lack of availability of sufficient long term debt, dearth of equity funds, withdrawal of tax sops and absence of quick decision making are the key reasons responsible for a sluggish infrastructure growth in India.”

            Advocating the need for long term bank finance availability for the sector, the industry body has suggested for mandatory increasing the bank lending by way of incentives.  “Considering the priority status to the infra sector, a certain percentage of exposure should be made mandatory for all the banks just on the lines of export financing” it said.  “Besides, obligatory targets should also be imposed upon private sector banks and foreign banks operating in India as currently, major portion of infrastructure lending is contributed by public sector banks”.

            It suggested that banks may be permitted to issue long-term, tax free bonds for the purpose of lending to infrastructure sector at a lower rate of interest.  Provisions may also the made by the Reserve Bank of India (RBI) to provide interest subsidies to the banks for their exposure in this sector, it said.  Incentives doled out to the infrastructure entrepreneurs earlier, should be restored and current regulations be amended, it assed.

ENERGY CONSERVATION

To achieve suitable indoor thermal conditions, one has two basic options:
either invest heavily in the purchase, installation, operation and maintenance
of HVAC systems;
or reduce energy costs by applying bio climatic principles to building
design.
The operating costs of heating, cooling, ventilation and lighting can be
significant, especially if the design and/or operation of the building is
suboptimal. Considering the fact that operational and maintenance expenses
grow with time and that problems usually get worse unless action is taken, it
makes good sense to place an emphasis on energy conservation right from
the start. In fact, energy savings add up over the years and translate into
cost savings.
Energy conservation has become an important aspect of building design and,
in some countries, a code-mandated requirement. The main objective is to
achieve indoor environmental quality, while balancing the requirements
for energy efficiency and overall energy conservation in an
environmentally acceptable manner.
Building retrofit or renovation costs are much lower than the costs for building
demolition and the construction of a new building. Energy conservation in
existing buildings is a priority, given that the lifetime of buildings is usually
more than 50 years and the existing stock of buildings is much greater than
new construction. Energy conservation measures for new and existing
buildings are already in process within several Member States of the
European Union, in accordance to the new Directives by the European
Commission on “Energy Conservation in Buildings”.
Energy conservation for heating and the reduction of heat losses are mainly
governed by thermal insulation of the building envelope. Thermal insulation
materials have improved significantly over the past decades in terms of
efficiency, safety and functionality. The current average heat loss of new
European buildings is about half of what it used to be for the pre-1945 building
stock. Nevertheless, the majority of existing buildings are poorly insulated,
since in most countries national thermal insulation regulations have been
enforced during the last decades. For example, in Greece, where the national
Thermal Insulation Code became effective in 1981, only 5% of the existing
residential building stock is insulated.
Heat losses through the building envelope are responsible for about 10-
25% of the total energy consumed in buildings, depending on outdoor weather
conditions and building materials. Consequently, a well insulated building
envelope can significantly reduce thermal losses in winter and heat gains in
summer, thus reducing energy consumption and operating costs, and
improving the indoor thermal conditions. The addition of an external cladding
façade, at an appropriate spacing from the main building “body”, on existing
and new buildings, creates an air gap that acts as a thermal buffer zone, thus
reducing heat losses in winter and heat gains in summer. Thermal insulation
5
materials should be added on the building “body”, for additional energy
savings. These rules apply to both existing and new buildings
Energy conservation for cooling of buildings is of primary concern in
Mediterranean countries. During the past decades, the use of mechanical air
conditioners (A/C) in southern European countries has increased dramatically.
This is primarily due to an increase of the living standards and the reduction in
price of A/C units. There is a clear trend of increasing sales with gross national
product (GNP) in EU member states. In Greece, sales of A/C units showed an
unprecedented increase of 900% during the late 1980s due to a series of heat
waves over a period of three years. The impact on the electric energy
consumption has been alarming. For the first time peak electric energy loads
occurred in Greece during the summer period. Similar trends have been
observed in most southern European regions, the Middle East, the United
States and Japan.
Solar control (shading) is a key design measure for minimising the heat gain
of indoor building spaces. The use of various shading devices to attenuate the
incident solar radiation can significantly reduce the cooling load and improve
the indoor thermal and visual comfort conditions. External shading is more
effective overall because the main amount of incident solar radiation is
intercepted outside the building and can be dissipated away from internal
spaces.

Difference between Architecture student and other fields student??

Seating infront of my drafting table i was just thinking of my past architecure studies and life...submissions,those late night studies , elevanth our model making , runnig for plotting , xeroxing the jurnals , computer failure befor the day of submissions....list will go on.. that was amazing..but whats the different between us and the other students like medical or enggi students? what do u think?? is there an difference??

architectural presentation-ASPHALT ROOFING

WHAT IS ASPHALT?

A dark brown to black cementitious material in which the predominating constituents are bitumens, which occur in nature or are obtained in petroleum processing.
Asphalt is a constituent in varying proportions of most crude petroleum and used for paving, roofing, industrial and other special purposes.

PHYSICAL AND CHEMICAL PROPERTIES
Asphalt is obtained from fractional distillation of petroleum.
Felt used for paper. This felt is saturated with asphalt shingles and sidings which is used as roofing.
Stabilizers like silica, marble, sandstone etc. are combined with asphalt to control its hardness, elasticity, adhesion and weatherability.

Fine surfacing materials like talc, mica are finely ground and used to prevent the various asphalt materials from sticking together when packed.
Colored granules like natural slate, marble, granite are crushed, screened and graded to sizes.This is used to produce permanent colors.

CATEGORIZATION
Asphalt roofing is categorized as:
Organic
Fiberglass
Fiberglass based asphalt shingles are manufactured with mat composed entirely of glass fibers of varying lengths and orientations. This fiber glass base is then formulated with a special asphalt coating.

TYPES OF ASPHALT ROOFING
There are 6 types of Asphalt roofing .
Surfaced rolls produced from surfaced products.
Sidings.
Strip shingles.
Individual shingles.
Smooth roll roofing from saturated felts.
Built up roofing.

ROLL ROOFING

The wood deck is first cleaned first from any dust.
Hot or cold Asphalt cement as recommended by roofing manufacturer is poured.
The starter strip which is 914 mm wide and has lengths of 43.89 & 21.95.
The strip is then nailed to the deck in 2 rows, which are staggered, and in each row the nails have cc of 304 mm.

The nailing is done on the top of the roll on an offset of 120.65 mm.
The overlapping portion on the starter strip is covered with Asphalt cement.
Then the next roll is laid on the Asphalt cement.The roll overlaps on the starter strip by a distance of 482.6mm.
This strip is also then nailed in the same way.
Roll roofing can also be laid vertically in the same fashion.

Types of roll roofing


STRIP SHINGLES

The wooden deck is first cleaned of dirt and dust.
Felt underlayment is then laid on the wooden deck.
Underlayment is provided to low,sloping roofs.The roll roofing is laid on the deck in the same way as shown above.
The tabs used for the roofing is equal to three shingles.

The starter course or course of full 3-tab shingles reversed is laid and nailed on the underlayment.
The first course is then nailed and then further courses are nailed.
Each course covers the nails of the course below it,giving it a finished appearance.
Care is taken that the edges of the tabs are staggered
This type of roofing is used for slopes of 3to 12 up to 4 to 12

INDIVIDUAL SHINGLES

·       The wooden deck is cleaned.
·       Felt underlayment is laid, the felt underlayment is in roll roofing.
·       Then the starter course of individual shingles is laid and nailed horizontally.
The starter course, which is horizontally laid on quick setting roofing cement and a starting course of quick setting cement in the vertical manner is also laid.

The next courses are laid and nailed staggering to the previous course.
Individual shingles are also found in hexagonal staple down shingles, which give a better aesthetical view and even Dutch lap shingles are also available which are kept in place by L type nails.
This type of roofing is used for roofs with pitch 4 to 12 up to 8 to 12.

Interlocking individual shingles


BUILT-UP ROOFING

·      Built up asphalt roofing consists of alternate layers of hot asphalt cement and asphalt saturated felts.
·      These layers are called 3-ply, 5-ply, etc., according to the number of layers of asphalt-saturated felt.
·      The finished surface consists of slag or various types stone chips.
·      This type of roof is used for roof surfaces with a pitch not greater than 3 to 12.
·      The life of 3-ply roofing is 10 years and for 5-ply roofing is 20 years.


5-ply built-up roofing


DISADVANTAGES

Deterioration begins early in product life-cycle as product sheds its protective granules
Susceptible to blow off in high winds
Scars easily when hot
Susceptible to mildew and moss
Environmentally unfriendly

Defects in organic shingles:
CUPPING
LOSS OF GRANULES


ADVANTAGES
Affordable Cost: Compared to other roofing products, asphalt shingles are relatively inexpensive.
Peace of Mind: Asphalt shingles have been around for over 100 years. They have a proven track record in our harsh climatic conditions.
Suitability: Asphalt shingles are available in a wide selection of sizes, styles and colours, suitable for most residential applications.

Warranty Coverage: Asphalt shingles are protected with warranty periods ranging from 20 years to Lifetime, which will suit any budget and needs.
User-Friendly: Experienced Do-It-Yourselfers can apply asphalt shingles successfully.
Low Maintenance and Easy Repairs: Other more expensive roofing products can require more maintenance, specialized tools, can be more difficult to repair and almost always require professional installation.

ADVANTAGES OF FIBERGLASS SHINGLES
Are more resistant to heat, which may cause blisters to form on softer organic shingles.
On most application, fiberglass shingles require the installation of an asphalt saturated felt underlayment.
Are more resistant to curling, which can happen with organic shingles after many years of service.
Roof assemblies covered with fiberglass shingles have a higher fire resistance rating than roof assemblies covered with organic shingles.

OTHER USES OF ASPHALT
Transportation - highways, railbeds for transit systems, airport runways
Recreational - running tracks, greenway trails, playgrounds, bicycle and golf cart paths, racetracks, basketball and tennis courts
Aquatic - fish hatcheries, reservoir liners, industrial retention ponds, sea walls, dikes and groins to control beach erosion
Residential - driveways, subdivision roads
Agricultural - cattle feed lots, poultry house floors, barn floors, greenhouse floors
Industrial - work sites, log yards, ports, freight yards, landfill ca
Waterproofing on roofs & tanks.
Used in tanking.
