Civil engineering2Executive summaryAbasementis a structural portion of abuildingthat is either partially or completely below thenatural ground level. From a structural perspective of a common man, one may think that allthe basements are designed equal. But the reality is that each basement design has its ownpros and cons. They can be at different levels according to the requirement of the buildingand the purpose of the basement to be used. In this office building, we need a basement forthe parking purpose. The construction of any type of basement is quite a difficult task and itis also a high-risk work that can affect the existing structures of that area because we need todig under the ground which affects the water table and the soil. The architects and thestructured engineers work together to simplify this problem and deliver any project on timewith cost-effectiveness.
Civil engineering3IntroductionThe Government of New South Wales has launched a program namedNewcastle UrbanTransformation and Transport ProgramTransport for NSW (TFNSW) is the main publictransport agency of the Government of NSW. The main purpose of this policy is to give andissues the policies regarding the all the models and kind of transportation that will help thecommoners to travel in the city. It also helps the local bodies to plan and construct the roadsto commute easily without any traffic-related infrastructure in NSW. The main reason whywe are doing this project and making a report about it is to present the necessary technicalinformation regarding the project like the construction of the building and the techniques tobe used for its construction. The main purpose of the said report is to present the design andconstruction of the structure of the most compatible basement foundation for the commercialretail project[ CITATION Cha182 \l 1033 ]. Transportation to NSW is responsible forimproving the transportation customer experience service, transportation policy andregulation, planning and administration of programs, transportation and infrastructureservices and freight. The Program has an objective to attract people back to the citycentre byreinforcing connections between the waterfront and the city, providing job opportunities,creating more public places and spaces, and developing better transport. The officialgoverned body has also announced the proper budget for the construction and management ofthe building and that is of 500 million dollars. The company wants to build an office withretail complex and the 1 level parking in basement and for that purpose, they acquire a land atHoneysuckle, Newcastle CBD.
Civil engineering4Site analysisSeventeen boreholes have been excavated from the existing basement floor level to depths of4m and 5m borehole logs are contained within this document. The base condition of the siteconsists mainly of sand and gravels and there is a layer of cohesive layer found at six metersbelow the ground level.As per our site conditions and the borehole test results, we will recommend building as thepoured concrete walls type basement. It is the common type of construction for any office. Inthis type of construction, we cast the RCC walls on the periphery of the building andwherever required[ CITATION Lim17 \l 1033 ].These RCC walls are long along the floorheight of the basement. These walls not only withstand all the load of the building but alsoresist the earth load or the load from neighbouring buildings. This technique of basementconstruction begins with spilling the base for the foundation of the basement. When they aredefined, the shapes are come in hand to keep the concrete wall spilt in place for the timewhen they are drying. Hollow concrete walls have proved to be stronger when compared toother kinds of basement walls.Figure: site plan
Civil engineering5Source:[ CITATION Lim17 \l 1033 ]Suitability and buildability of the various basementconstruction methods in response to specific siteconditionsFor any work for basements, construction regulations are applicable and cover areasincluding ventilation, drainage, roof heights, waterproofing, electrical wiring, water supply,and means of escape and so on. See the construction regulations for more information.The basement can be subdivided into three categories, depending on their location,construction time in relation to the property superstructure above ground and depth. A briefoutline of the differences and the main issues corresponding to each of them are describedbelow.Types of Basement1.RefurbishmentIt may be necessary to lower the floor to increase the space of the head, holding adjacentwalls, increasing lighting as well as ventilation. It commonly involves improvements toexisting or a new waterproofing system, and replaced finishes and accessories[ CITATIONHer18 \l 1033 ]. The benefit of this type of basement is that it adds value to the property andalso provides the more usable space.2.New Garden BasementNew basement can be constructed adjacently to the already existing property, usually in agarden or backyard space new structure under the ground, with a green roof planted or terraceat garden level.
