You are required to write a `Critical Review` of the two In-Situ Tests written below on one Single-Sided WORD DOCUMENT (Not more than one page!):

A) Flat Dilatometer Test (DMT)

B) Field Vane Shear Test

Your `Critical Review` should possess two Sub-Titles (a) `Critical Assumptions related to these Tests`, and (b) `Advantages and Disadvantages of both Tests

A test of a driver’s perception/reaction time is being conducted on a special testing track with wet pavement and a driving speed of 65 mi/h. when the driver is sober, a stop can be made just in time to avoid hitting an object that is first visible 555 ft a head. After a few drinks under the exact same conditions, the driver fails to stop in time and strikes the object at a speed of 35 mi/h.

Question - 6 Determine the Braking distance for sober driver?

Question - 7 Determine the sober driver perception-reaction distance?

Question - 8 Determine the sober driver's perception/reaction time?

Question - 9 Determine the perception/reaction time of driver after drinking?

Find the planar density on the (1 1 1) plane in atoms per millimeter squared for BCC tungsten. R=0.137 nm. b.Describe how a S-N curve is constructed and how it can be used to predict if a component will or will not fail due to fatigue.

What is the are the issues that void filled asphalt over its limit?

A square footing 1.5m X 1.5m is located at a depth of 1.0m. The soil has the following properties: γ = 17.5kN/m3, c= 20kN/m2 and Φ = 34o. The footing base and ground are horizontal. if the horizontal component of the weight = 20kN acting at the height of 4m parallel to the side of footing, and vertical component is 500kN, determine ultimate bearing capacity and factor of safety. using Hansen’s analysis

Derive an equation for the available NPSH for a pump is bellow the water in the suction reservoir.
Support your derivation by drawing.

Write a critical review of two In-Situ Tests (Flat Dilatometer Test "DMT" and Field Vane Shear Test)

The critical review should include critical assumptions related to these two tests and the advantages and disadvantages between them.

3. For a dual carriageway new road scheme, the average annual daily flow (AADT) of one way traffic is 24,000; 2% are commercial vehicles. No channelisation is expected to occur. Design a foundation and bound layers of a pavement. The subgrade surface modulus = 40mpa = 4%CBR. State any assumptions made, including the choice of design method and sketch a cross section of the final pavement design.

(N.B. there are hundreds of potentially correct designs depending on the choices of design methods and materials. Any submissions that include identical designs may be investigate for potential collusion).

. Discuss the potential short term and longer term impacts of introducing a road bridge link to the Isle of Wight with reference to each of the four stages of the four stage transport model and on carbon emissions

Discuss the mechanisms of permeability and hydraulic gradients and their effect on groundwater movement.

A construction company specializing in drilling horizontal holes across rivers or lakes with diameter ranging from 12 to 24 inches is currently engaging in a construction project in Dallas/Fort Worth Area. According to the regulations of the municipality where the projects locates, construction activities cannot be carried out during weekends and holidays. Therefore, during the coming Thanksgiving, the construction will be suspended. The construction company could resume its work after Thanksgiving. As a construction project engineer for the project, what kind of problem can you predict? Please write briefly about your prediction BASED ON THE CONCEPT OF EFFECTIVE STRESS? Please explain how effective stress would affect the drilling procedures after a long lay-off

1. The discharge through a rectangular channel 4.4 m wide is 16 m³/s. The Manning’s coefficient n is 0.03.
   1. Determine the normal depth when the slope is 0.008. Check whether the flow is sub or supercritical.
   2. If the normal depth is to be kept at 2 m, determine the slope.

‘There is no settled law on the meaning and effect of letters of intent. The court must decide each case on its facts . . . I am reminded of the basic legal requirements of offer, acceptance, intention to create legal relations, and consideration.’ Twintec Limited v GSE Building and Civil Engineering Limited EWHC 605 [2002] (HHJ Kirkham) Discuss this statement and consider whether or not a contractor’s legal rights can be protected if work starts based on a letter of intent.

Your task is to develop quantified Risk models of two Risks of interest to you. This is an academic
exercise and its purpose is to make you familiar with the process of quantified Risk modelling and
to show me you understand the theory and the practice.
a) Write up each Risk as a case study that explains the Risk in detail and describes the proposed
control measures.
b) Estimate/judge the values that could realistically be given to the various parameters relevant to
modelling Risk and explain your reasoning to me. Don’t spend inordinate amounts of time
trying to justify any of the values that have to be estimated/judged in order to complete the task
(eg. does a death cost $3M or is it $3.2M? Is the Exposure 20 times a year or 18?). However,
ensure that you do have justification for the values you use as I am not interested in you simply
using a number with no justification.
c) Use your spreadsheet to estimate the position of the Risk line, using any necessary “reality
checks”. In other words, justify or even make a clear statement of the inadequacies of what
you have done and the need for further investigation. Estimate the Risk value.
d) Propose a possible control measure change/improvement and estimate the associated
implications for productivity, recurrent costs and/or capital requirements. I am well aware
these may based on judgement unless you have a close knowledge of a particular case.
e) Provide me with an explanation of the anticipated effect of this proposed control measure on
each of the parameters that determine Risk and use this to justify a reduction in the Risk value
estimated before this improved control measure is applied.
f) Use this to estimate the effect of the improved control measure on one or both (as appropriate)
of recurrent costs and payback period.
