Seven Storey Multifunctional Building Project Plan Construction Essay

Published:

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

The proposed building will be located at the location of the current building, Pao Siu Loong Building.

The building will be a seven - storey multifunctional building with length of 40m, width of 20m and height of 54m. The height between the floors will be 5m, whereas for the seventh floor is the multifunctional court, thus the height will be 10m. The ceilings of each floor will have a thickness of 2m.

The building will have offices, a canteen, a learning centre, lecture rooms, classrooms and a multi - functional court. The building can be used by the staff and students for both social and academic purposes. For safety reasons, this building will have two emergency exits, occupants can escape from both sides of the building through the exits if there is an emergency. More details are available in section of Floor Plans.

FLOOR PLANS

The building will consist of 7 floors, each floor with different functionality to meet needs of students and staff. Lifts are use as the main transportation connecting the floors in this building. No lifts are at the 7th floor as that floor is used as the multifunctional court. Occupants will have to access the court through the staircase in the emergency exits. For the handicap occupants, a handicap stair lift will be installed on the staircase connecting the 7th floor. Details of each floor are stated below:

The 1st floor of the building will be a canteen. The increasing trend of the number of staff and students shows that the additional canteen will meet the demands of staff and students.

The 2nd floor of the building is proposed to be a learning centre that provides a place for learning, studying and socializing.

The 3rd floor will be used as offices for Chinese Language Departments and lecturers, the space allocated will be larger than the previous building - Pao Siu Loong Building. This will create a comfortable working environment for the staff and lectures

Figure 5. The floor plan of 3rd floor

On the 4th, 5th and 6th floor, there will be 2 lectures room and 4 classrooms. This can solve the current problems of insufficient classrooms in the university.

The 7th floor will be the multifunctional court. The court can be used for sports competitions and final examinations.

MATERIALS

All of the materials used in this construction are in compliance with the sustainability principles and will cause the least harm to the environment and human. The chosen materials are long lasting and durable, hence the long term maintenance cost of the building will be low. The waste produced are non hazardous and will lower the disposal cost as no special treatment for the waste before disposal is required.

Transparent cement

The cement is a matrix of cement and resin that allows the penetration of light to provide the natural lighting while maintaining the structural strength of the whole building. The cement also creates the aesthetics appearance of the building.

Eco Friendly Bricks

It is also known as Eco Bricks, made by pressurizing the byproducts from coal power plant. The bricks have a comparable quality and are relatively cheaper compared to the conventional bricks. Its production has zero contribution to the global warming as it does not generate CO2.

CONSTRUCTION PROCESS

Demolition

The demolition of Pao Siu Loong Building will be a building implosion, thus the demolition time can be shortened. The building will be ensured to fall into its footprint, without causing any damage or disturbance to any other buildings near to it. A site clearance will be done on the building to remove flammable, hazardous and potentially explosive materials. The site will be covered in thick geotextile fabric and will be fenced to prevent the public access. Explosives are placed on the supports of building. The removal of supports through explosives will cause the building to collapse itself. Cleanup and disposal of the remains will take place once it is confirmed the building has completely collapsed.

Main Construction

(a) Footings

The method used to construct the footings will be pole construction as the site of construction is a sloping land. A pole will be placed into the hole that is dug into the ground and mixed with concrete. Steel reinforcement is not required in this method, thus making the pole construction the most economical way in construction of footing on the sloping land.

(b) Floor

Brick piers will be used for constructing the floor supporting system as they are cost effective. The piers will be attached onto the concrete pad footings directly. For the floor frame, inline joists fixed to bearer with joist hangers will be used as it can carry more loads comparing to the conventional joists on bearer.

(c) Slabs

Prefabricated concrete slab will be used in the construction for the proposed building. To improve the thermal insulating properties of the slab, a layer of expanded polystyrene that acts as insulation layer, is casted with the concrete slabs.

(d) Wall

Eco Bricks and transparent cement will be used to construct the walls of the building. The bricklaying time is less than the conventional bricks, thus it can shorten the construction time. Transparent cement is used on parts of the building to allow light penetration to reduce the reliance on lighting system.

Finishing

(a) Windows

Double glazed glass windows will be installed on each floor. The window is composed of double paned glass and has the property of selective transmission. It only allows penetration of light with certain wavelengths that is beneficial to human. It can absorb or reflect parts of the infrared ultraviolet that is harmful to human under long - term exposure. In addition, it is also thermally insulative and has noise reduction properties due to its double pane glass structure.

(b) Doors

Swinging wooden doors will be used for the doors in the building. All doors will have the fire retardant and fire resistant coatings that can withstand the extreme temperatures up to 10000C for an extended time to allow more time for escaping in case if there is fire emergency.

(c) Paints

Zero VOC paints with mixture of fire retardant and fire resistant coatings will be applied on both exterior and interior of building, allowing the whole building to withstand a higher temperature especially during the fire emergency. Zero VOC paints has reduced toxins and low odor, it benefits every people especially those with allergies and chemical sensitivities. The paints do not produce any hazardous waste, thus the disposal cost and environmental impact are low.

Installation of Services

Once the construction and finishing of building are completed, the installation of services in the building will take place. Sewerage and drainage system, electrical system, centralized air - conditioning system, water pipes system, LED lighting system, wireless network system and other services will be installed. Lifts will be built after the completion of electrical system in the building. All of the electrical appliances installed are energy efficient and durable, hence the maintenance cost are expected to be low.

In order to comply with the safety regulations, the security systems inclusive of intrusion alarms and CCTVs, the complete fire safety system which includes hood system, backflow devices smoke detection system, fire alarm system, emergency lightings, fire hoses, fire extinguishers and fire sprinkler system will be installed throughout the building.

Completion

A series of test will be carried out for 2 weeks to check on the structural strength, designs and other services in the building before its handover. Modifications will be done if necessary.PROJECT SCHEDULE
