CAREER EPISODE 2
Introduction:
CE 2.1 I will discuss my second career episode where I will talk about the work
experience, I have earned while working on the construction of a residential villa
with certain specifications requested by the client. The project activity started in
September 2015 and was completed by August 2016. I worked as a Structural
Design Engineer in UMANG PATEL CONSULTING CIVIL ENGINEER AND
STRUCTURAL DESIGNER. The organization was headquartered in Ahmedabad,
India.

Personal Engineering Activity:
CE2.6 To exertion on the engineering errands in the venture, I guaranteed to get
ready myself to be competent sufficient and reskill myself. I tacit the mission
purposes in detail and deliberate by the engineering methods and procedures
required to attain the goals established by the venture management. I joined to
numerous preparing courses on STAAD.Pro, AutoCAD and ETABS to ponder
almost computer program to be utilized amid the venture. I too alluded to many
magazines and journals such as International journal of Advanced Structural
Engineering (IJASE), Journal of material science, International Journal of civil
engineering and Technology, publication of concrete Exploration which are
associated to structural engineering to arise the essential information.
CE2.7 I worked thoroughly with my administrator to decide the extend conveyance plan. I
arranged the diagram of the plan and conversed with the investors to look for
response and inputs. I ensured to allocate tasks to the project resource team
considering their area of interest and expertise in the areas. Post consolidating the
variations to the design, I jolted the development activities obeying to the
concurred timelines.
CE2.8 I worked with the local municipality administrators to discover the utmost actual
codes and stipulations utilized in the venture. I escorted the government authorities
who were on location visit and clarified them the scheme plans and designs.
utilizing national codes and determinations is concerned, I implemented the
National Building Code of India (NBC) to the construction activities. The mentioned
code is an inclusive building code that offers national guidelines to regulate the
building construction activities in India and we required to follow to the codes as
said within the National Building Code of India (NBC). I studied total episodes of
apposite codes to form beyond any doubt that the project activities are followed to
the codes.
CE2.9 Earlier to the start of the engineering task in the venture, I gotten all the
engineering drawings, designs, project plans and the correlated in progress. I
carried out an exhaustive evaluation on the received development plans and
architectural drawings. I approved the plans in contradiction of the concurred codes
and guidelines as well as the plan standards established by the client, I carried out
my valuation by calculating the several loads and affirmed that the plans projected
by the architects are well and sustenance the actual erection. I planned an actual
load resistance design for walls and column. I similarly checked in case the design
would be able to resist the apparatus and lift loads.
CE2.10 I used ETABS to define the various loads as required to design the building. I
assigned loads for external walls and internal walls after defining the loads. Then I
assigned live loads for the entire structure including floor finishing. I followed the
standard IS 875 1987 PART 5 for load combinations. I followed the standard IS

456:2000 to work on the concrete design on the structure. The following image
illustrates the building plan.
CE2.11 I used concrete slabs as the most important structural element to design the
building. I made sure that the horizontal slabs of steel reinforced concrete are
between 100 to 500 mm thickness and they are used to construct floors and
ceilings, while I ensured to have the thinner slabs to be used for exterior paving. I
considered the thickness and width of the slabs, and density of the concrete, dead
load, and live load to calculate the total load. I calculated the design moment for
cantilever beam by using the formula Mu = wl2/2.
CE2.12 I used one-way slabs to design the bedrooms, gym, restrooms, and kitchen. I
obtained the effective depth, effective span, reinforcement requirements, cracking,
defection and development length by adhering to the standard IS: 456-2000. The
following is an illustration of a one-way slab.

CE2.13 To design the parking lot and hall, I implemented the one-way continuous slab by
diving the length into equal bays by providing beams perpendicular to length. As
negative bending moment is produced in the one-way continuous slab at the top of
intermediate supports, I provided negative reinforcement over intermediate
supports. As maximum shear occurs at the support next to the end support, I
checked the slabs for shear at this support. Also, I checked for deflection at the
locations of maximum positive bending moment. I checked the slab for
development length at the end support. The following diagram is an illustration for
one-way continuous slab.
CE2.14 I met a stimulating condition when I found the cracks actuality created on the
asphalts of the housing constructions and roads that were near to the building spot
at the appearance of winter. I took care a fully analysis of the problem and
examined the erection place and neighboring areas as well. I alluded to the
geotechnical reports once more to discover any evidence that seem have brought
about in this problem. I found that the matter happened since of water logging. The
root cause was need of seepage that come about in water logging and the
dampness permitted debilitating of the concrete of the asphalts.
CE2.15 To suggest a genuine tenacity and resolve this problem, I had a talk with my
administrator to took for his endorsement to arrange a viable and everlasting

resolution for it. After getting the sanction, I worked on concluding an operative
substitute to confirm that the asphalt does not split within the imminent. I actualized
my designing ability to discover that real issue lied with the establishment of the
construction. This fortified me to recommend a resolution to make a divider of
reinforcement concrete rib at a distance of 3 meters to ensure that the pavement
relates to the retaining walls. The following illustration is representational for the
reinforcement ribs.
CE2.16 I provided guidelines to laborers to excavate a more profound zone that would be
able to get bigger aggregates and, to permit fixing a bridge of reinforcement
concrete which could be larger than the size of the asphalt blocks. The
determination was the greatest suited to transaction with the matter, I gotten the
mandatory endorsements from my superintendent and project owner.
CE2.17 I come across additional interesting condition after the achievement of the
development. I seem see that the side wall of the developments was taking water
infiltration. After a close review, I found that the walls of the construction on the
ground floor started absorbing moisture though there was no rain for the whole
month. Upon inspection and sample tests, I found the water penetration to be a
result of the construction runoff through the gutter channel design. To stop the
walls from further being moisturized, I considered the different wall types to be
constructed on the first and second floors. I ensured to design a water-resistive
wall if even though some water would penetrate the outer surface, the moisture
could be controlled to penetrate the wall. I designed the Barrier wall systems as it
includes walls filled with mortar or grout collar joints and offers adequate of the
masonry and the integrity of the mortar or grout to prevent moisture from reaching
the interiors.
CE2.18 I worked on properly designing, detailing, and constructing the barrier wall
systems. The following is a presentation of the barrier wall model I constructed.

I worked on the construction of the barrier walls by focusing more on the integrity of
the collar joint, as well as the bed and head joints between units. I filled these joints
solidly with mortar to avoid creation of gaps that may later result in pathways that
could allow water to the interior and bypass the storage capacity of the wall
assembly. I ensured to completely fill the collar joints by following grouting. Also, I
took care that spaces less than ¾ in (19.1 mm) are not grouted. I performed purge
coating to the face of the inner masonry Wythe and buttered the back of brick in
the exterior Wythe to fill the collar joint. I integrated flashing into barrier walls to
ensure that the water that penetrates the exterior Wythe is well controlled.
CE2.19 To finalize protection procedures, I arranged various conferences with the
investors and conversed the safety actions carefully. I ensured that the designs are
correct as faulty construction or overloading might have hampered the safety of the
building. Also, I checked the stresses for the designs to ensure that there is no
threat to the stability of the building post construction. I made it compulsory for the
site labours to be prepared with the Personal protective equipment (PPE) such as
head protectors(helmets), safety vests and glasses. I confirmed following to the
proposed legal guidelines, environmental directions, and health requirements.
CE2.20 I met with my administrator department such as supervisor, manager double a
week and talk about the development growth and the tasks experienced in the
venture. The conversation schedule was moreover to discover the finest way
determinations to the tests. I prearranged my regular plan actions based on the
achievement status of the creation engineering works. I worked with cross-
functional groups such as Planners, Mechanical Engineers, Electrical Engineers
and Geotechnical Engineers and many more. I get it the development necessities
exceptionally very well so that they might give me with the desired help.
CE2.21 I took up the additional responsibility to take care of the documentation activities. I
made the various reports and papers to be displayed to the venture partners. The

reports generally comprised the place inspection and quantifiable estimation. I
utilized Microsoft Office to make the reports and documents. I documented total
reports for forthcoming reference.
CE2.22 I considered the discarding of the wastes happening through the erection actions. I
took care about the environment whereas arranging the squander and guaranteed
to accomplish squander isolation earlier to the transfer. I confirmed that the
workers are very well skilled not to blend the squanders and obstruct the situation
of environment.
CE2.23 I welcomed citations of the resources earlier to deciding the dealers. I scrutinized
the quotations based on the fetched and convenience of the materials and chosen
the greatest accessible material at attainable costs and granted the offer to the
pertinent retailer. I seem spare a great sum of fetched by obtaining the materials.
CE2.24 The wander realistic a part of challenges and it was extreme to total the venture
exercises in the fit plan, I safeguarded to work solid and finish the development
within the decided deadlines. I ensured that the project cost does not exceed the
allocated budget. I tracked the project proceedings and prepared progress reports
every day to be sent to the key project stakeholders. I tried my best to resolve the
issues with effective team contributions as well as individual contributions from the
project team and all the stakeholders. I made sure to provide effective resolutions
to the challenging situations faced in the project through regular debates with the
sponsors. I was capable to perform the development plan by effectively and
delivered the best quality work.
Summary:
CE2.25 The project was very challenging as the scope was very huge and several activities
had to be carried out to complete the project activities. As the project was planned
to be executed in a populated area, the safety of the residents was quite a big
challenge to deal with. Disposal of construction waste was also quite challenging
as there were no disposal area nearby. By working on implementing innovative
ideas to resolve these issues offered me a lot of confidence and helped me grow
as an efficient Structural Engineer.
