I want a 22 page research project on the topic above. I’m adding abstract here. Only problem is I need it in next 8 hours.

ABSTRACT:

A successful construction project is the one that brings out the best quality, and better use of time and economic resources. For the success of a construction project the quality management should provide the project with the related tools, techniques and procedures in a effective manner. Quality management isn’t an external factor, but an integration of all operational and managerial processes of the construction project. Quality planning, quality assurance and quality control are the major parts of a quality management. The paper includes the outcome of research methodology decided by authors based on interviews of project participants and analysis of data.

When it comes to quality, the construction industry is quite behind the other industries. This industry has always suffered from instability, productivity issues and low standards. This paper is aimed at investigating the quality issues in construction environment. In order to determine the best way for quality management practice, data has been collected for solicitation of information from the participants in the project by quantitative research strategy and questionnaire survey. The questionnaire survey is going to be carried out across various companies in the USA. Various medium to large scale companies are taken into consideration for the collection of questionnaire samples for analysis. The results will be analyzed using SPSS and AHP software.

SOIL MECHANICS PROJECT

CMCE 2456 – Fall 2020

A homeowner want to level a rear yard. You visit the site and realize that the work will require the
construction of an about 5-ft-tall retaining wall. Your subsurface exploration indicates that the soil
in the yard is homogeneous medium to fine SAND with trace amounts of silt (USCS Classification
SP) to a depth of 25 ft below ground surface. N-values suggest that the material is classified as
NYC Building Code Class 3b material; groundwater was not encountered. Laboratory tests
indicate that the sand has a moist unit weight of 122 pcf and an angle of internal friction of 33°.

PROBLEM STATEMENT
Size the retaining wall such that it has a geotechnical factor of safety against sliding and
overturning of 1.5.

Assumptions
 Assume a vertical surcharge of 300 psf is applied on the high side of the wall.
 The wall foundation must bear 4 ft below the lowest grade for frost protection.
 The stem of the wall must be a minimum of 12-inches thick.
 The wall footing must be a minimum of 12-inches thick.
 Ultimate friction factor for mass concrete against clean fine to medium SAND is 0.4.
 Consider passive pressure in the analysis.
 Lateral pressures due to the surcharge have a uniform distribution based on a pressure
equal to 50 percent of the vertical pressure.
 Unit weight of reinforced concrete is 150 pcf.

Assignment
1) Produce an engineered-quality scaled drawing.
2) Include your calculations showing your assumptions, pressure diagrams and resultant
forces.
3) What is the applied bearing pressure under the wall?
4) Is the applied pressure less than the Building Code allowable?
5) If passive pressure is discounted, what is the resulting factors of safety?
6) Provide a cover letter with your submittal.

NOTE: Your calculation must be on engineering paper, they must be neat and without
scribbled corrections.
