List the steps in the planning process.

1. Refer to the example bore-log in the presentation. Consider one layer in sand and one layer in clay. Explain how the soil description is arrived at.

Write a short note on the pre-tensioning and post-tensioning methods of prestressed concrete with the aids of sketching.

A crew of mechanics at the Highway Department garage repair vehicles that break down at an average of 10 vehicles per hour (approximately Poisson in nature). The mechanic crew can service an average of 2 vehicles every 10 minutes with a repair time distribution that approximates an exponential distribution. The crew cost is approximately $50 per hour. The cost associated with lost productivity from the breakdown is estimated at $80 per vehicle per hour (or any fraction thereof). Which is cheaper, the existing system with one service crew, or a revised system with two service crews? The average waiting time for adding the second crew is 0.02.

A sample of biological culture was submitted to a chemical laboratory for analysis of the percentage by weight of each major element. The composition of the cells by weight was found to be 48.9% C, 5.2% H, 24.8% O, 9.46% N, and 9.2% ash.

1. Prepare an empirical formula for the cells

2. Determine the COD/organic weight ratio for the cell

3. Determine the theoretical oxygen demand including both COD and NOD

   (nitrification oxygen demand)

4. If the organics are 80% biodegradable, what is the ultimate BOD of the sample?

5. What is the TOC?

explain one method of field compaction control

Describe the effects of climate change on hydro-electric power generation?

Produce a report detailing the planning process for an OLE construction activity (min 600 words), using a recent work as the basis for the report. The report should detail the following: • Strategic planning process for engineering possessions

• Planning of engineer’s trains and on track plant

• Ordering and supply of materials

• Manpower requirements

• Road rail machines requirements

• Possession arrangements

• On track plant detailed plans

• Interface with other engineering functions

• Isolation of Traction Supply

• Bill of quantities for activity

• Manufacture, order and delivery of OLE components

• Pre-assembly / delivery of components

• Detailed construction activity

• Work activity Plan (Gantt Chart

) • Progress reporting arrangements

• Risk Assessmen

t • Disposal of waste materials

• Mechanical checks carried out prior to opening to service

• Electrical checks carried out prior to opening to service

• Collation of as built records

• Handover from constructor to maintainer

(The topic about citation) .
Write a summary of a scientific topic at your choice in civil engineer.You should cite at least two different types of sources (Book, Article, report, website, etc).The citation may be a paraphrase or summary; the direct quotation should not exceed 10%.Use proper citation style, e.g.APA,The summary should not exceed one-page including the references ( on the program word 12 font size and single line space)Note:(1) Avoid plagiarism, copying and pasting.(2)I want the references that you used it.
