Write a short letter to the owner stating your companies intention to bid the job and name one specific idea to improve or "value engineer" the project. These projects often are tight budget-wise, so it is not uncommon for contractors to work with the engineers to get the best possible outcome for the owner.

Discuss the result of the design of fillet weld for a tie member of a truss consist of an angle section ISA 100 x 75 x 8 mm of Fe410 grade, is welded to an 8 mm gusset plate. Design a weld to transmit a load equal to the full strength of the member. Assume shop welding. If the gusset plates are connected by 2 angle section ISA 65 x 65 x 6 mm back to back to the same gusset plate. Design a weld to transmit a load equal to the full strength of the member. Express your opinion on how the length of the weld are different for both the design form your results.

Give short answers to the following: (a) (i) Write the equation for Mohr-Coulomb shear failure criteria for soils. Define the variables in the equation. Also, show how this equation is represented in a graph. Label your graph. (ii) Name two laboratory tests to determine the shear strength of the soils. (b) The soil below a concrete dam has a porosity of 0.4 and density of solids of 2.7 gm/cm3 . To ensure safety against piping, the specifications state that the critical gradient which cause piping should be 6 times the exit gradient. What is the allowable exit gradient?(c) In calculation of consolidation settlement we assume that the consolidation is onedimensional (in vertical direction only). Is this a reasonable assumption? Why? (d) Why the permeability of sand increases with the increase in grain size of the sand? (e) What are the advantages and disadvantages of a triaxial compression test? (f) Unconfined compression test was conducted on a saturated clay. The vertical stress at failure was 200 kN/m2 . Sketch (not to scale) the Mohr circle and find the shear strength parameters for this soil.

Hong Kong was ranked the second most sustainable city in Asia
after Singapore according to Arcadis’
Sustainable Cities Index (SCI) in 2018. Hong Kong obtained top
marks in economic aspects but trailed
in some other important parameters. A green group recently warned
that the Hong Kong government
might fail to reach the previously promised environmental goals,
particularly waste reduction. The
Hong Kong government definitely needs to take more actions to
enhance the overall sustainability in
a more balanced manner.
What are the three systems of sustainable development and what
characteristics a sustainable
solution needs to hold?
