11. Given a concrete mix as follows:

Cement            1 bag               3.15

Water              60 lbs.              1.0

Sand                230 lbs.            2.65 (5% excess moisture)

Gravel             380 lbs.            2.66 (2% excess moisture)

            Determine the quantity of each item that you would use for a 27 cubic foot mixer (you must only use whole bags of cement) weights for sand and gravel, bags for cement and gallons for water (ONE (1) CUBIC FOOT OF WATER = 7.48 GALLONS).

a member in a braced frame supports an axial compressive load and end moments that cause bending about both axes of member. A second order analysis was performed with factored loads and and reduced members stiffnesses to obtain the moments and axial forces. USE LRFD and selet the lightest W shape of A992 steel? Axial=140 k. Mux= 150 ft-kips. Muy=150 ft-kips.

Mux=75 ft-kips. Muy=75 ft-kips.

1. You are a farmer and you are building a fence for your horses.  The fence will have four sides that are all the same.  The total budget for the project is $800 at $200 for each side.  The schedule for the project is 8 days (assume 8 hours per day), estimated at 2 days for each side.  The project started Monday morning and it is now Thursday (of the same week) at the end of the day ‘today’.  You assessed the progress and determined that 25% of the total work has been completed (1 side of the fence).  You have already spent $800 for the work that has been completed as of today.

            Answer the following questions (Please show your work related to all calculations.):

1. What is the planned value as of today?

2. What is the earned value for the project?

3. What is the actual cost for the project?

4. What is the project schedule variance?

5. What is the project cost variance?

6. What is the schedule performance index?

7. Discuss what these metrics mean regarding the performance of the project.

Q1.

A) List and differentiate the roles between the key players on a construction project.

B) In civil engineering, contractors may be broadly classified as either general or specialists, distinguish the two classes of contractors.

C) In a scenario of a project for construction of high rise lecture rooms building at Mulungushi University, a client, a Consultant and a Contractor are all Civil Engineers. Who is responsible for issuing instructions to the Contractor and explain why? (assignment question)

D) Who is responsible for paying temporal works on a construction site? Give a reason why?

-Describe your experience / familiarity with the most common construction standards concrete, Masonry, Metals, Wood.

-Why are standards important?(Related In construction)

-Describe your familiarity with ISO standards and Quality Management Systems.

-Why are Quality Audits important? Describe quality failures that you have seen?

-What are some of the quality slogans that you have seen in your day to day life?

What properties do you use to determine the grade of steel (ie modulus of elasticity)?

a. Explain how the catchment area is determined when calculating surface runoff.

b. How can the adverse effects of urban development on downstream runoff be minimized? Name the principles and discuss.

You are using the rational method for calculating the surface runoff in a rural area. The area is flat, permeable grassland.

Calculate the runoff coefficient (C).

B05 - Construction Surveying - Assignment 8

Explain the process for establishing the line and grade for a sanitary sewer line connection to an existing municipal sanitary manhole. Include the type of sewer flow, the importance of the pipe invert and reach of the sewer in determining the slope of the pipe, factors that determine the use of manholes, the use of batter boards and offset stakes, minimum ground cover required. In addition, discuss the use of visual aid such as field notes and a simple plan and profile drawing in establishing the line and grade.

the previous answer in wrong / incomplete

b) Explain in detail the various types of defects/failures that a structure may encounter to reach: (i) Ultimate Limit States. (ii) Serviceability States. Note: You may answer each part of this question in a number of paragraphs. It would also be useful if you provided some preliminary AutoCAD images to substantiate your answer

2 Prepare a formal Notice of Non-payment from a Contractor.
3 What is the advantage of using a standard set of ‘Conditions of Contract’?
4 Prepare a typical agenda for a pre-commencement meeting on an Onshore Pipe Laying
project

Draw and explain the structure of different types of clays
