Do all the questions. be neat and organized

Construction claims most often stem from a handful of recurring causes: delays, scope changes, differing site conditions, and contract ambiguities. Each of these can derail a project’s budget and schedule — and damage working relationships in the process. Which of these do you think is the hardest for a project manager to prevent, and why? What proactive steps — in documentation, communication, or contract management — could reduce the likelihood of a claim arising from that cause?

Research Paper Submission

Submit your research paper here.

Please consult your course SLOs on the syllabus to guide you in selecting your research paper topic. The title and content must be related to topics cover in this Performance Appraisal course.

Students are to first submit their research proposal by April 10, 2026, for approval to ensure that their topics are relevant to the course. This is to avoid rejecting completed papers at the end of the semester because they didn’t address topic(s) relevant to the course. Secondly, the paper must be an original document written by the student. Plagiarized or papers copied from other sources will be rejected for academic dishonesty and recorded as “0” grade. Final paper is due on April 20, 2026, at 11:30 PM.

Lab 6C- Compaction Problems

Complete and turn in your work on paper.

Problems 5.1-5.6, Chapter 5 Compaction (pages 82-83 of the textbook)

++++++++++++++++++++++++++++++++++++++++++++++++++

5.1 At a borrow site, sandy soil was excavated. The soil had t
= 19.3 kN/m3,
w = 12.3%, and Gs = 2.66. The soil was dried, the maximum and minimum void ratio tests were performed, and emax = 0.564 and emin = 0.497
were obtained. Determine the relative density of the soil at the
borrow site.
5.2 The soil in Problem 5.1 is used to fill an earthwork, and 75% of relative density is required in the field compaction with 10% water content.
Determine the required total unit weight of the soil t
for this earthwork.

5.3 For a given soil with Gs = 2.65, plot the d versus w relations for S = 40%, 60%, 80%, and 100% for a range of w = 0% to 20%.

5.4 The standard Proctor test was performed for a soil with Gs = 2.66, and
the results are as follows:
Water
Content, %
Moist Weight
in Mold, gf
5.6 1420
7.9 1683
10.8 1932
13.3 1964
14.8 1830
16.2 1630
(a) Plot the d versus w relation.
(b) Determine d,max and wopt.
(c) Calculate S and e at the maximum dry unit weight point.
Compaction 83
(d) What is t
at wopt?
(e) What is the range of water content if the relative compaction (R.C.)
is required to be 90% of the standard Proctor d,max?

5.5 The modified Proctor test (ASTM D 698, method C) was performed for
a soil with Gs = 2.70, and the results are as follows:
Water Content, %Moist Weight in Mold, gf
6.5 3250
9.3 3826
12.6 4293
14.9 4362
17.2 4035
18.6 3685
(a) Plot the d versus w relation.
(b) Determine d,max and wopt.
(c) Calculate S and e at the maximum dry unit weight point.
(d) What is t
at wopt?
(e) What is the range of water content if the relative compaction (R.C.)
is required to be 95% of the modified Proctor d,max?

5.6 The following table shows a standard Proctor test result. Soil type was
SW according to USCS. The soil is used for filling a small trench that
was excavated in a parking lot. Determine the required d and the range
of water content for this job. Use Table 5.4 as a guideline.
Water Content, %Dry Unit Weight
d, kN/m3
3.5 14.3
6.2 16.8
9.2 18.6
12.5 18.7
15.3 17.6
18.6 14.6
