Healthcare sector in India
   
Indian government expenditure on health care is the highest amongst all the developing countries. The expenses of the healthcare industry comprise 5.25% of the GDP. There are even chances that the health care market could experience a hike and attain a figure ranging $53 to $73 billion. The Indian Health Care Industry earns revenues accounting for 5.2% of gross domestic product.

Indian healthcare industry comprises of hospitals and allied sectors which is projected to grow 23% per annum to touch US$ 77 billion by 2012 and according to the current estimated size of US$ 35 billion. The Industry has registered a growth of 9.3 % between 2000-2009, as compared to the sector growth rate of emerging economies such as China, Brazil and Mexico. There would be increase in number of public and private healthcare facilities which are expected to propel demand for the industry, accounting for another US$ 6.7 billion.

Majorly the Indian Health Care Industry and Fortis Hospitals plans to invest US$ 53.7 million and plans to expand the facilities for the pan-India.Columbia Asia Group, which already has six hospitals in the country- Asia's leading hospital chain, plans to ramp-up its operations in India by opening eight more multi-specialty community hospitals with a total capacity of 800 beds by the year of mid-2012. Total investment of US$ 177.1 million for 14 hospitals is projected.
In Hyderabad, the NarayanaHrudayalaya has inaugurated the phase-I of the 5,000-bed health city which is the Hub for the multinational corporations. The company plans to expand its presence to seven more cities to take the total number of hospitals to 14 in the next 2-3 years.

Cochlear Ltd plans an Australian medical devices company to set up its wholly-owned subsidiary in India, to provide better patient and product support. In next five years the Company also plans to invest about US$ 15 million.
 
How MEP interfaces in Hospitals can be done using Interarch structural steel
   
Mechanical, Electrical & Plumbinginterfaces tend to be the most critical part of any building's requirement, and especially in a hospital environment, these services are critical to saving lives. Interarch structural steel interfaces easily with Hospital requirements taking into consideration
HVAC requirements for hospital ventilation and air-conditioning
Special air quality, circulation and pressure for operating theaters (HEPA filters)
Positive and negative pressure rooms for patient isolation
Pressure cascade for surgical department
Laminar flow for special theaters and clean workrooms
Patient controls & interface (at bedside)
Special drainage of radioactive waste
Task lighting vs. comfort lighting
Operation & maintenance

Besides MEP and HVAC services, Hospitals focuses on other aspects like maintaining the water supply and drainage systems for normal and radioactive waste, fire alarm system etc.

Interach engineering takes into account MEP loads are given by the consultants and design the building considering the requirements, and our structural members are manufactured to accommodate these connections at site. Provisions for these loads are given either vertically for ducts and shafts or horizontally in form of castellated beams and floor cutouts. Chiller rooms where MEP requirement is heavy can also be delivered in Structural Steel.

 
Connection Details in Structural Steel
   
By Mr. Vishal Khandelwal, DGM Design Interarch Infrastructure & Mr. Neeraj Lohani, A.M. Design

The common connection used in steel structures can be broadly classified into the following categories:

Shear Connections

A connection which is only capable of transferring shear from one connected part to another, but no moment is transferred, it is known as Shear connection or Pin connection. Since, the shear is practically borne completely by the web of a beam and the tension compression couple created by moment is mainly borne by the top & bottom flanges of the beam, in shear connection only webs are connected and the flanges remain unconnected. A shear connection is only provided at the zero bending moment locations of a beam, which is typically the end support location of a simply supported beam (e.g. floor joists).

Common shear connections in use are
 a. Double clip connection
 b. Fin plate connection
 c. End plate connection

Moment Connections

A connection which is in addition to the shear connection above is capable of transferring the flange tension and compression forces (due to tension, compression generated by bending moment at the connection location) is referred as a moment connection.

The common forms of moment connections in use are
 a. Extended end plate moment connection
 b. Flush end plate moment connection
 c. Spliced moment connection
 d. Seated moment connection
 
Fire Proofing in Structural Steel
   
The structural elements of a building need to be designed to withstand the effects of building compartment fires, so as to minimize the likelihood of structural collapse. The use of steel framed construction and in particular the use of fireproofing materials is known to provide fire resistance levels for the steel elements of buildings.Fireproofing is achieved by applying fireproofing covering materials to thermally protect the underlying steel from the heat of the fire. The type and amount of fire proofing material is dependent on a number of variables, some of which include
 
Size of steel members in question
Fire severity
Fire rating or duration of exposure to a given fire
Time of application of the fireproofing covering
Budget
Aesthetics
Location of project

Conventional spray applied materials

These are the oldest and at present the most widely used form of fireproofing material. These are relatively low density materials, (at least when compared to concrete) which typically are supplied in bags, and which are mixed with water and sprayed as a type of slurry onto or around the contour of the steel profiles.

The thicker the applied material, the higher the fire rating, within maximum thicknesses which prove the material's adhesiveness to the steel during fire testing

Board Materials

Board materials, like conventional spray applied materials, have been used for a long time. Manufactured board materials are cut to size and fixed around steel sections, in essence "boxing" them in to provide the necessary fireproofing. Fireproofing boards must be able to limit the amount of cracking or spalling so as to limit the spread of hot gases to the underlying steel structure

Intumescent Materials

Intumescent materials are those which expand to many times their original volume when heat is applied to them. They are widely used in the Passive Fire Protection or Fire Stopping market. Examples of such materials include intumescent fire collars for protection of plastic pipes or Intumescent sealant for around steel pipes. Intumescent paints can be applied at relatively low thicknesses when compared to conventional spray applied materials, and when they are subjected to the heat of a fire, expand or swell to form a thick insulating char around the steel members.

 
Customer Testimonial- Young Builder Program at K.R Mangalam Institute, Delhi
   
Thanks and congratulations to your team for an interactive session on pre-Engineered steel buildings. Hope this will help our students to think in a different direction of construction. We shall be in touch and also try to arrange a plant visit to Pantnagar to take the maximum benefit of it.

 
Project Management Tip: Correct Procedure for Building Erection
   
Column Erection
Column is arranged with all fixtures & painting duly completed
Lifting sling is fixed to the column at exact position of lift
Guy ropes are fixed to the column before lifting
Lifting equipment lifts the structural column vertically and is positioned in the Pedestal
Anchor bolts nuts are fixed and tightened
Guy ropes are tied as shown in the figure
Column plumb is checked and sling is released using boom lift or scissor lift
   
Braced Column Erection
Same Procedure is followed for lifting the second column
The portal beam is the primary tying member between the two columns. It is lifted using Crane and boom lift used for bolting the portal beam
The eave strut is immediately erected after the erection of second Column
Bracing rods should be lifted and fixed to the adjacent columns. Hill side washers are used to tighten the brace rods
The same procedure is followed for erection of the columns on the other side of the grid
