Course Name: Estimating & Costing Max. Time: 1 hr 30 min
Course Credit: 3
Note: All Questions are compulsory
Assumption if made should be written explicitly
Q l. A small steel frame structure is to be erected and an estimate of the cost is required. The unloading, erection, temporary bolting, and plumbing will be done by a crew of 1 foreman, 1 crane operator, and 4 structural steel workers with a crawler crane. The bolting will be done by two structural steel crew using power tools. The painting will be done by a crew of 3 painters with spray equipment. For unloading at site erection , temporary bolting and plumbing allow 7 labor hours per ton for the roof trusses and 5 labor hours per ton for the remaining steel. Assume 60 crew hours will be required for bolting and 1.11 labor hours per ton for painting.
Assume appropriate equipment productivity cost, labor cost and cost involved in any type of development process. The profit earned maybe kept as 12 % of all cost.
Given the material required: A 36 structural steel for truss: 15 tons and columns: 50 tons. [8 marks]

Course name: Construction Safety and Health
Note: Attempt all 6 questions. Each question is worth 5 marks.
Q. la Construction by its very nature is hazardous. What are different types of hazards in construction?
Q. lb List the diseases caused during construction.
Q. 2 Describe major elements of worlds best practice in construction safety management.
Q. 3 Author Allan Holt writes, Human error as a simple catch-all explanation for accidents is now discredited. The term, if it means anything at all, does not provide an adequate description of the many ways in which the failure of people at all levels in organization can contribute to the complex phenomenon we call accidents. It is more useful to think about human failure ... The human failure involves
1. Active failures
2 Latent failures
3. Errors
4. Slips
5. Lapses
6. Mistakes 7 Violations
8. Routine violations
9. Situational violations, and
10. Exceptional violations
Define these terms such that the differences between them become clear.
Q. 4 As the key document pulling all the threads of the management process together, the safety policy details the arrangements made to comply with relevant regulations. List three essential elements of a safety policy. Explain each element.
Q. 5a Risk assessments are used to generate method statements. What are method statements?
Q. 5b For difficult to identify hazards, we use inductive analysis. What is inductive analysis?
Q. 6 State 6 important rules for successful meetings

Question 3. Given an array a[l...n] of integers, consider the problem of finding the longest monotonically increasing subsequence of not necessarily contiguous entries in your array. For example, if the entries are 10, 3, 9, 5, 8, 13, 11, 14, then a longest monotonically increasing subsequence is 3, 5, 8, 11, 14. The goal of this problem is to find an efficient dynamic programming algorithm for solving this problem.
