He performed this project while working at “Company name “and worked on it from August 2016 to May 2017 under the supervision of “supervisor name “who was the lead construction engineer for this project.

Engineering Activities of Geotechnical Engineer:

  1. To perform a field investigation in the initial part of the project and collected all the necessary information on the local conditions and geology.
  2. To perform slit trench excavations and underground utility mapping and prepared a report on its outcomes.
  3. To perform various tests in the laboratory and investigated slit trenching and utility survey.
  4. To perform the chemical tests to determine pH, sulfate and chloride ion concentration in soil-water extracts along with conducting calcium carbonate tests.

  10. Again, to analyze the results and provided the foundation construction considerations.
  11. Finally, to perform a chemical attack on buried concrete and provided conclusions.

Problems and Solutions:

  1. Problem 1 for Career Episode 1 and its solution

In the project, author was determined the moisture content in the coil, but the results from initial tests were contrasting to each other which was a major problem. He had separated the water content specimen to different parts, and the problem was found to be because of the lack of drying of the water specimen in some of the samples. Hence, he allowed it to dry for several hours and repeated the process for seven set of samples such that he was able to conclude on the exact content of moisture in the soil.

  1. Problem 2 for Career Episode 1 and its solution

The modulus of vertical subgrade reaction required for the structural design of footings was computed using the required equation assuming homogenous soil stratification but found the value to be differentiating with the assumed value. He investigated into the problem and performed field plate load test at the proposed foundation level for the verification of obtained value and used the expression as given ACI-335-2R section 3.3.2 and recommended to take the value as 100≈150MN/n^3

Problem & Solutions:

  1. Problem 1 for Career Episode 2 and its solution

During the testing of the soil, author faced a problem. The acceptance criteria said that the average cone resistance should not be below 15 Mpa for top 4 meters from the ground surface and should not be below 12 Mpa below 4-meter depth. But he could not achieve the soil specification as per the criteria. This may cause the deformation of the soil during the construction. Such soil cannot resist the maximum allowable load of the structure to be constructed. So he released the important to increase the cone resistance of the soil. Therefore, he performed a cone penetration test to determine it and analyze the soil properly. Then he performed heavy tamping of dynamic compaction method to improve the weak soil and also used dynamic replacement method in some areas. Finally, he was able to solve the problem successfully.

  1. Problem 2 for Career Episode 2 and its solution

Next, he faced the problem during the dynamic compaction or replacement method. The crane was used in this method which should be able to handle the minimum load of 25 ton and should be able to drop in from a minimum height of 20 meters. During the operation, there occurred degradation to a wire rope. Due to this, the wire rope jumped out of the system. This hindered the running project work. He noticed that the occurrence of the problem was due to bird caging, corrosion and extreme wear. This caused degradation to the wire rope. He solved the problem by providing proper lubrication. After applying lubrication, it reduced the friction of the wires and protected from the corrosion.

Geotechnical Engineering Career Episode 3

Project Name: CONSTRUCTION OF LANDFILL FACILITIES FOR HYDROCARBON CONTAMINATED SOIL (GROUP - B) IN NK AREA

Project Type: Work Based Career Episode

Demographics: The project was conducted for the Kuwait Oil Company where this project was undertaken by the contracting company called “Company name” located in Kuwait. The project was started on January 2014 and was completed on January 2015 where he occupied the position of Geotechnical Engineer.

Engineering Activities of Geotechnical Engineer:

  1. To visit the construction site in Northern Kuwait which was 5 km from the access field gate 3 of the KOC.
  2. To prepare a site layout by its observation and measurements collected during the site visit and developed a methodology along with a master schedule to conduct the construction work sequentially.
  3. To develop appropriate plans/ideas for the systematic execution of construction and installation, works as per the pre-set requirements.
  4. To make a report on all the earthwork required on the site which included excavation of the bulk to form a required base for the landfill, filling and compaction of the dug soils to create a perimeter bund around the excavation which would allow the disposal of the contaminated soil by a combination of landfilling and land raising.
  5. To prepare a report ensuring the quality assurance of the construction works and keep a daily record on all the site activities and materials being delivered to the site.
  6. To check the specifications of the material and to collect a representative sample of it and sent it for the quality test.
  7. To inspect the dispatch and placement of the geomembrane and assure that the installation was done according to the design.
  8. To assist the detection test of the electrical leak and prepare a detailed report to be submitted to the company.

Problem & Solutions:

  1. Problem 1 for Career Episode 3 and its solution

During the project, author faced a problem while preparing the construction surface. The surface where the construction work was going to be introduced needed to be dry, robust and without any deformities. But the climatic condition of the site at the time of construction was very windy, and the temperature was very high. Therefore due to the adverse climatic condition, some areas of construction failed to produce the surface according to the project requirement. The dryness of the surface was not proper as per the planning thus he reported the problem to the company and along with the client including the remedial measure. To solve the problem, the surface detected with high dryness was ripped off, and water was added to it. The ripped surface was then spread over the surface, levelled and compacted after passing through some test.

  1. Problem 2 for Career Episode 3 and its solution

Another problem he faced and overcame was during the installation of geomembrane. During the installation of geomembrane, the team encountered residual VOCs in the soil. The cause of the problem was suspected to be the air quality issue encountered due to the vapour intrusion of sub-slab. As per the rules of the company, he reported the problem to the company who sent a team to inspect the problem. After completing the inspection work, he initiated the remedial works as per the instruction of the company. To solve the problem, a system called Liquid Boot Plus was installed which offered a venting system having a low profile. The system was incorporated with the geomembrane. Therefore, the problem was solved with a little assistance from the company.
