What characteristics of aluminium and mild steel make a difference in resilience and toughness?

- Considering chemical composition for each.

why Ultimate tensile strength and ductility are important factors

Define rework in construction project and milestone in construction project and give example .

Sketch a ring-barrier diagram for a signalized intersection which shows eastbound and westbound
with permissive lefts concurrent with the through movements (single ring) while northbound and
southbound have leading left protected (2-ring) phasing. Clearly annotate your diagram using
standard NEMA numbering, omit right turn movements, label the rings and the barriers.

9. During the layout of a site, it is determined that the slope distance between point A and point B is

If reducing the waste at the source could save waste generators money and would avoid many of the waste disposal problems, why isn’t there more source waste reduction?

The Queensland Government proposes to develop a high-speed train to link Gold Coast and Brisbane. The Government would like the train to travel at speeds in the range of 150-225 km/hour. It is expected that the train will run from Coolangatta to South Bank stopping at Robina, Nerang, Helensvale, and Coomera before running express to South Bank. The Government would like the elapsed time for travel between the Coomera and South Bank station to be approximately 30 minutes.

Your company has been chosen as the consultant to prepare an EIA report on the proposed fast-train network. Develop a preliminary EIA report for this project such as identify requirement and extent of EIA, Significant issues, Impact and mitigation plan for each significant issues

Waste water treatment is a crucial process to ensure that the waste water can be safely recycled back to the environment. However, there are certain challenges or issues related to this waste water treatment that can endanger the environment. In your opinion (supported by journal or academic references), what are those challenges and how can civil engineers prevent those happening>

Give an example and explain in detai lwhat measures you would undertake to calibrate and validate your mode lin SIDRA.

1. How is BOQ (Bill of Quantities) related to change order payment in construction projects?

2. Explain if owner has direct relationship with the subcontractors. What happens if the owner interferes into the work of the subcontractors.

the reinforced concrete tied column that is part of braced frame sized to the dimensions 375mm by 300mm .the column carries vertical ultimate load Pu=490kN (dead load only PD=134kN) and ultimate moment about strong axis Mu=110kN at top and Mu=117kN at bottom bent column in single curvature. if the clear height of the column Lu=4.80m k=0.83f'c=28MPa and fy=420 MPa , determine the reinforcement required

Design of Rectangular Beams with Tension Reinforcement Design a rectangular beam section (i.e., select b, h, and the required tension reinforcement) at midspan for a 22 ft-span simply supported beam that supports its own self-weight, a superimposed uniform dead load of 1.25 kip/ft, and a uniform live load of 2 kip/ft. The material properties are f 0 c = 4, 500 psi and fy = 60, 000 psi. Consider a clear cover of 1.5 inches to the #4 stirrups. Follow the procedure described in Example 1 of the class lecture notes; i.e., you start with an assumed reinforcement ratio and then determine tentative values for b and d. For the initial guess, you may estimate a self weight of 0.40 kip/ft (approximately 12% of 1.25+2 kip/ft)
