Magnidus, in partnership with Baruah Developers and Infrastructure Pvt. Ltd. (BDIPL), organised a day-long public workshop in Jorhat on the 25th of January, 2014. It was conducted with the intention of spreading general technical awareness about building construction and related subjects. The workshop was attended by several conscious citizens of Jorhat, including senior engineers, officials of the Jorhat Municipal Corporation, students and general public. The focus of the workshop was in throwing some light on the importance of following building byelaws, hiring the right consultants, using good quality materials etc. The significance of designing climate responsive buildings was stressed upon. The concept of Green Buildings was also introduced briefly. This presentation was a part of the workshop.

Webster’s Dictionary:
“A Structure intended or used as a habitation or shelter for animals of any
kind but especially a building or edifice for the habitation of man, a dwelling
place, a mansion”.
Oxford Dictionary:
“A building for human habitation, especially one that consists of a ground
floor and one or more upper storeys”.
A House is to live in, not to look on

Importance of Structural Engineer
• Structural engineers design structures to withstand stresses and pressures, such as weather
and human use. They ensure buildings and other structures do not bend, twist, collapse or
vibrate and remain strong and secure throughout their use.
• Structural engineers help to design most structures including houses, theatres, sports venues,
hospitals, office blocks, bridges, oil rigs, space satellites, ships and aircraft. They work in close
partnership with architects.
• Structural engineers have to choose appropriate materials, such as bricks, concrete, wood and
metal, to meet design specifications. When construction has begun, they are often involved in
inspecting the work and advising contractors.
• They also examine existing buildings and other structures to test if they are structurally sound
and still fit for purpose. Structural engineers have to make efficient use of funds and materials in
order to achieve structural goals.

What are the responsibility of a Site engineer
A site engineer is part of the site management team, and takes some of the responsibility for
security, health and safety, and organising and supervising materials and people. Site engineers
mark out the site, make sure designs are applied correctly and liaise with main and sub-contractors
and the site manager. Regular liaison with the client, its representatives, and any consultants is
another key part of the job.
What are the responsibility of a labour contractor and
Mason
1) The labour contractor can not take responsibility of safety measures of your construction nor he can give
you the structural design.
2) His first and foremost duty is to understand the detail drawing prepared by a structural engineer.
Neither he can reduce nor he can add anything without permission from the Engineer.
3) He will ensure that his Mason and labour will perform their duty as per schedule and norms given by the
Engineer,

Rain Water Harvesting
Benefits
• Reduces demand of supplied water
• Reduces flooding
• Recharges groundwater
• Free
Uses
• Washing
• Flushing
• Irrigation
How much?
Say 10mm (0.01m) rain everyday on a 100 sqm. roof, on a monsoon day
Total water that can be harvested per day = 0.01 x 100 = 1cum. or 1000 litres
Enough for 7 persons

35. 25 January 2014
BARUAH DEVELOPERS &
INFRASTRUCTURE PVT. LTD.
Drainage Recommendations
• Site should not be raised more than 6” (150mm) above adjoining road level
• Storm water drainage plans should be submitted to Municipality for permission before
construction
• Projects with Rain Water Harvesting schemes should get fast track clearance
• Boring without Rain Water Harvesting should be prohibited in Urban Areas

Some Common
Construction Mishaps

37. 25 January 2014
BARUAH DEVELOPERS &
INFRASTRUCTURE PVT. LTD.
Honeycomb In RCC
1. In concrete, a rough, pitted surface resulting from incomplete filling of the concrete against
the formwork, often caused by using concrete that is too stiff or by not vibrating it sufficiently
after it has been poured.
2. Voids in concrete resulting from the incomplete filling of the voids among the particles of coarse
aggregate, often caused by using concrete that is too stiff.
3. In sandwich panel construction or in some hollow-corridors, resin-impregnated paper is
fabricated into a network of small, interconnected, open-ended, tubular hexagons laminated
between two face panels to provide internal support
