Paper specific instructions:


       1. There are a total of 65 questions carrying 100 marks. Questions are of multiple choice type or
          numerical answer type. A multiple choice type question will have four choices for the answer with
          only one correct choice. For numerical answer type questions, the answer is a number and no choices
          will be given. A number as the answer should be entered using the virtual keyboard on the monitor.
       2. Questions Q.1 – Q.25 carry 1mark each. Questions Q.26 – Q.55 carry 2marks each. The 2marks
          questions include two pairs of common data questions and two pairs of linked answer questions. The
          answer to the second question of the linked answer questions depends on the answer to the first
          question of the pair. If the first question in the linked pair is wrongly answered or is not attempted,
          then the answer to the second question in the pair will not be evaluated.
       3. Questions Q.56 – Q.65 belong to General Aptitude (GA) section and carry a total of 15 marks.
          Questions Q.56 – Q.60 carry 1mark each, and questions Q.61 – Q.65 carry 2marks each.

       4. Questions not attempted will result in zero mark. Wrong answers for multiple choice type questions
          will result in NEGATIVE marks. For all 1 mark questions, ⅓ mark will be deducted for each wrong
          answer. For all 2 marks questions, ⅔ mark will be deducted for each wrong answer. However, in the
          case of the linked answer question pair, there will be negative marks only for wrong answer to the
          first question and no negative marks for wrong answer to the second question. There is no negative
          marking for questions of numerical answer type.

       5. Calculator is allowed. Charts, graph sheets or tables are NOT allowed in the examination hall.

       6. Do the rough work in the Scribble Pad provided.

 A multistory building with a basement is to be constructed. The top 4 m consists of loose silt, below which
 dense sand layer is present up to a great depth. Ground water table is at the surface. The foundation consists
 of the basement slab of 6 m width which will rest on the top of dense sand as shown in the figure. For
 dense sand, saturated unit weight = 20kN/m3, and bearing capacity factors Nq = 40 and N = 45. For loose
 silt, saturated unit weight = 18kN/m3, Nq = 15 and N = 20.Effective cohesion c' is zero for both soils.Unit
 weight of water is 10 kN/m3. Neglect shape factor and depth factor.

 Average elastic modulus E and Poisson’s ratio  of dense sand is 60 x 103kN/m2 and 0.3 respectively.
