ACKNOWLEDGEMENT With grateful heart I would like to acknowledge my gratitude towards everyone whoever has helped me upon my completion of the internship.

I would like to express my gratitude towards the Founder & Principal architect Ar. Atanu Chakraborty of Prakalpa Space Kraft Pvt. Ltd., Kolkata for giving me wonderful learning opportunity under him in his esteemed firm and has always been an inspiring role model in dedication towards architecture. He has been an amazing mentor and as well as amazing human being, teaching everyone the various skills required to become an architect.

Experience at Prakalpa Space Kraft Pvt. Ltd. has been filled with instances where one can feel the commitment of the firm to nurture the interns into developed professional who can handle the several requirements of the emerging design market. Given the size of Prakalpa, I never thought the training and mentoring will be so personalised. I was paired with a small team of talented designers and mentors who made sure I was involved in every phase of the design process.

I would also thank all my colleagues at Prakalpa, few of them being different architecture college seniors and the ever-ready-for-help nature. Ar.Sumana Halder, Er.Gargi Roy. Also, I like to forfeit my respect to Ar.Sumita Dhara and Ar.Sanjukta under whom I’ve learned a lot from in the technicality part of architecture. I’ve been taught how to design and prepare the drawing list of the project for the construction.

My special thanks to my senior Ar.Mona Kaushiki and Ar. Susmita, who helped me and guide me during the training period. Also my friends Antara, Kumar Gaurav, Saumya & Pallavi for always being there for me.

I would like to thank my professors from Birla Institute of Technology,Mesra who helped me build a stepping stones as I entered the field of architecture.

RVICES

Â

As Architecture is a social art that touches all human beings at all levels of their existence everywhere and every day, it needs to be thoroughly scrutinized about the safety aspects. In addition to that due to the substantial cost escalation with time and other crucial commitments involved, the timeframe of completion of a project is a sensitive issue. Team Prakalpa is conscious about the deadlines of the projects it handles. They observe an interesting rotational policy to ensure that all the ongoing projects are steadfastly progressive towards their completion stage. The Master Architects of a project is also functional as the Associate Architect of another project being executed by the firm. This chain policy of mutual association among its Architects and Engineers ensures that in case emergency due to the unavailability of any one, the project development does not encounter any obstacles during execution.

COL LOR SCH HEME

2.8.2. ELE EVATION N TREAT TMENT The front faaçade of STA AR MALL comprises c off different arrrangements of materialss, forms and colors, which whenn unified creaates a compo osition that sstands out in n the dull andd monotonous backgrounnd and yet dooes not break k the harmonny of it’s surrrounding. The T various kindds of materiaals used in thhe façade treeatment are P Polycarbonaate sheets, Mild M steel frame works, ACP P claddings, Cement fibeers board, Coolored anodiized aluminuum tubes etc. Some of whicch are discusssed below.

2.8.3. MA ATERIALS 2.8.3.1. CO OLORED AN NODIZED ALUMINIU UM TUBES S A. ADVAN NTAGES : 

Corrosiionresistantt. Aluminum m oxidizes quickly,, and the resuulting surface coat of alum minum oxide reesists furtherr corrosion, by air, water, w and chhemicals.

This pro otective coatting is clear, coolorless, andd nonstainingg.



Colorab ble: Aluminu um can be easily colored d by anodizaation, and hoolds paint exxtremely well. Alluminum cann be finishedd in various ways. w



Lightweight: Alum minum weighhs about a third of what ssteel does. That T makes itt inexpennsive to ship and can alsoo contribute to making a lighter macchine when thhat is desirablle.



Economical. Although we stated above that aluminum is not the cheapest material, it is still more economical than brass or stainless steel, so is often the best option for non-corrosive applications.



Strong: Aluminum has the highest strength-to-weight ratio of any metal.

B. DISADVANTAGES  

Limited color selection Touch-up of anodized product that is severly damaged is more noticeable than air dry touch up paint for painted products.

2.8.3.2. POLYCARBONATE ROOFING

A. ADVANTAGES 

High-Quality



Nearly Unbreakable



Bullet Resistant



Lightweight



UV Resistant



Perfect for Greenhouses



Resistant to Extreme Temperatures





Affordable

B. DISADVANTAGES Despite the many advantages to using polycarbonate panels as roofing material, there are only a couple of downsides. One downside to polycarbonate sheets is that they are not scratch resistant and denting or scratching on the surface is possible if extra caution and care are not taken.

2.8.3.3. CEMENT FIBER BOARD

A.    

ADVANTAGES Durability Longevity Fire safety Environmentaly neutral

B.DISADVANTAGE    

Cost ( Expensive) Maintainence Matters Installation Issues Insulation value : The R value of cement fiber board is 0.5. The higher the insulation R value the more effectively the material returns.

The plan of the building is elongated in form due to site constraints. Doubly loaded long corridors are hence incorporated.

Entrance is not grand enough for a mall as it should have been.

Parking is not sufficient at peak hours.

Fixed glass treatment in food court traps heat rays and hence makes it uncomfortable to seat near the glazing in day time during warm weather.

There is insufficient number of toilets in each floor.

No fine dining near food court. Restaurants are at 5th floor.

Glass house in 3rd floor, which is meant for small events, traps heat rays and makes unfavorable conditions for organizing events.

Top floor (currently used as terrace) has provision for temporary roofing to accommodate banquet halls with truss roofing.

Movement is simple throughout the plan in each floor causing no confusion for users.

Central atrium with polycarbonate dome provides ample natural lighting at the entrance hall.

Guard rooms- Functional and well maintained.

Observation on Site

1.

  

Plinth beam construction work in progress.

Beam is not straight in many areas.

Shuttering should be done in line before concreting.

2.

  

Sand filling work in progress.

Sand filling is done to bring uniformity to foundation bed, to minimize the resistance.

If the footing is placed directly on rock bed, even a small amount of vibration on earth (during an earthquake) will make the structure collapse.

Hence sand is used to minimize the resistance.

3.

     

Tie beam construction work under progress.

Tie beam connects to or more columns at plinth level or at any other level above ground. Tie beams are also a type of plinth beam.

These beams do not convey any floor loads and only acts as length breakers for columns.

They carry axial compression.

They prevent columns from buckling.

In the following image, 16mm and 8mm dia. rods are used for the frame work.

4.





Block wall projected from 0,0 level at plinth is supported by brick support which are not recommended.

Timber shuttering is being used which is sagging on various places. This will lead to deformed construction of block wall.



5.

Ply board shuttering or metal shuttering is recommended to avoid these kinds of problems occurred during construction.

 

6.

Lift pit construction done.

Shuttering not done properly, due to which the surface of the pit is not in true shape.

  

Reinforcements can be seen coming out of plinth beam area.

This can be injurious to workers on site.

To avoid this hooking is done in L shape or C shape.

NOTE: Timber shuttering is not recommended on site as it can lead to sagging of the wooden member and also undergoes expansion and contraction. Therefore it is recommended to used ply board shuttering or metal shuttering as they have smooth surfaces, are strong in nature, durable and can be reused multiple no. of times.
