Construct a block diagram depicting an open loop arrangement for the signals and transfer functions defined in 2). [3 Marks]

Assume zero initial conditions and a step input with magnitudes 𝛼 and 𝛽 for each of 𝑑̅ (𝑠) and 𝑒̅ (𝑠) respectively. Find the concentration output 𝑦(𝑑). [10 marks]

Using MATLAB, produce a unit step response for the output 𝑦(𝑑) and verify the result by comparing it with the analytical result derived in 4). Select the time scales so that both the transients and the steady state output are visible. [10 marks]

Assuming 𝑑̅ (𝑠) = 0, specify the parameter values that needs to be changed for the speed of the response to increase. Explain and justify your reasoning using appropriate mathematical functions and step response plots? [5 marks]

Assuming a unity negative feedback loop, derive the following transfer functions

Verify that the closed-loop system is stable by graphically computing the poles and zeros. [4 marks]

Analytically calculate the steady state error due to the disturbance and the reference signal. What can you infer from the values obtained? [7 marks]

Prove that the output 𝑦(𝑑) will only track steady-state targets if there is an integrator in either a feedforward controller 𝐢(𝑠) or the plant 𝐺(𝑠). What other condition is required? In addition, using a mathematical derivation, specify the requirement for disturbance signals to be totally rejected, that is to have no steady-state impact on the output? [12 marks]

Use MATLAB to investigate how offset and performance varies as you change the scalar controller gain 𝐾𝑝. Give some generic conclusions based upon what you observe. [7 marks]

Critically discuss any two technologies of your choice, showing how they can be used on this project at any point in the asset life cycle, to improve sustainability,

Project Management Practice

You have been appointed as the Project Manager for the project and your CEO has asked for a strategic report that satisfies the following:

Critically evaluate the risk management process and develop a risk register and associated matrices to both identify and perform a risk analysis for dealing with the project and environmental impact of the proposed project including the demolition of the existing school. A minimum number of 12 (6 each) risk issues should be identified and justified.

The need to ensure quality throughout the project is essential. Critically analyse quality management systems and processes and develop a Quality Management Strategy (QMS) for the project.

Based on existing literature critically analysis Value Management in relation to the project and make recommendation to the client on feasible solutions which may be adopted to give the best Value for Money. (VfM)

To improve the performance, innovation is essential (Ernstsen et al., 2021). Critically discuss any two technologies of your choice, showing how they can be used on this project at any point in the asset life cycle, to improve sustainability,

The UN’s sustainability goals – how can the construction industry contribute?

The UN’s sustainability goals – how can the construction industry contribute? Background The UN’s sustainability goals are the world’s joint work plan to eradicate poverty, fight inequality and stop climate change by 2030. The UN’s sustainability goals consist of 17 goals and 169 sub-goals.

The goals will function as a common global direction for countries, businesses, and civil society.

Both countries and businesses are now working to find out how they can contribute to meeting the sustainability goals. What does this mean for the Construction industry?
