Question
Chapter 3, Problem 9RQE
To determine
List the reasons of changed conditions in a building contract, and also mention the clauses of the typical contract related to the changed conditions in a building contract.
Suppose separate contracts are given for building foundation and all remaining work, and the second contractor finds that the foundation is incorrectly calculated, find whether he will be able to assert a changed condition.

Text Book Problem 7.82 (page 261) Consider the total head-loss in the system forthis flow is 18.56 ft (head-losses in first and second pipe are 13.83 ft and 4.73 ftrespectively). Please show numerical values for EGL/HGL at the beginning/end/intermediatechange point. (Point distribution: elevation determination 5 points, EGL, HGL lines 4points).(I think we are just using the values provided for head losses to solve this problem)
Calculate the BMs (bending moments) at all the joints of the beam shown in Fig.1 using the moment distribution method, and draw the Shear force diagram and Bending moment diagram for the beam shown. The beam is subjected to an UDL of w=65m. L=4.5m L1= 1.8m. Assume the support at C is pinned, and A and B are roller supports. E = 200GPa, I = 250x106 mm4.
