Effective Communication

Derrick’s  critical reflection   After nearly 13 weeks of effective communication, I realize my weakness are mostly in my writing. For instance, for my first assignment on introductory letter, I need to add more clear examples to support my assertion. In addition, I need to work on my grammar, punctuation and capitalization errors. For instance, I do not need to capitalize “Civil Engineering” but inste ad just write “civil engineering”. I realize that I will always do it so that it looks neat. Secondly, I tend to use too many commas and also lack of parallel verb structure. In this course, I definitely use lesser capitalization unnecessary and to try my best to check my verb tense.      In my second assignment which is reader response, I  thought I will do quite well as I always able to summarize and generalize stuff easily. However, I realize that my weakness is on the citation. I tend to always forget to cite properly and also my grammar tends to be very weak in expressing what I

Li, B. (2015). Geotechnical properties of biocement treated sand and clay. Doctoral thesis, Nanyang Technological University, Singapore. Retrieved from https://hdl.handle.net/10356/62560 Li Bing, associate professor of Civil and Environmental Engineering at Nanyang Technological University is the author of this investigation on the potential uses of biocement on low permeable material. This article focused on the application of biocement to improve the soil conditions for geotechnical engineering. In this research project, its aim is to use microbial technologies to study biocementation effects on low permeability materials such as clay. Microbially induced calcium carbonate precipitation (MICP) is the most practiced biocementation method. The properties of MICP treated soil were tested with various tests. For instance, unconfined compression tests, triaxial tests and direct simple shear tests. The article also mainly uses three sets of bacteria for this experiment. They are U

Introduction 1.1 Background Information This proposal has been reported in response to the request for developing engineering solutions to strengthen soil to prevent differential soil settlement under structures. With the Singapore government turning to underground spaces to reduce land demand in Singapore, one can expect the number of underground works to increase. However, underground works have been synonymous with damages to nearby existing structures. This is due to differential soil settlement, a phenomenon that occurs when the soil settles at a different rate. If this happens under a structure, cracks can occur on the structure due to uneven distribution of loading into the soil. This can cost the contractor resources as compensation may be required. To prevent such issues from worsening, measures such as soil strengthening can be put in place when identified. One such soil strengthening method can be to cycle a solution of calcium and biocementation bacteria across the f
