A project planning proposal should be provided before the project start and by using the plan to control and coordinate the project. This project will for the construction of proposed redevelopment of Upper Wong Tai Sina Estate Phase 3 of a 41-storey non-standard domestic block of three wings building link to a central core and approx. 114m high from ground floor to main roof level and Curvilinear Cvered Walkway including associated Site formation works and External works in 28 months from Date of Possession. In order to construction this project, I set out a project planning plan for this project. 1. Hoarding erection for site boundary 2. Ground investigation field works for the determination of rock stratum is required 3. Monitoring check point to be provided during the site formation works 4. Construction typical floor of structural steel frame super-structure and RC core wall of lift and one lift machine room on the top. 5. Construction building envelope of precast facade with tiles in every elevation. 6. Fire resisting coating to be provided for the protection of the structural steel member. 7. Provision of internal and external finishes works and building services such as HVAC, electric work, fire services, plumbing and drainage works. 8. Provision of seven lifts (one fireman use) inside the building. Similar as-built project photos shown as below for reference. BNV6102 Bid Strategy group project Group 6 Page 34 3. Programming 3.1Method Statement To complete this project on time and within 28 months, the following construction techniques shall be adopted. 3.1.1 BIM shall be used to monitor and control the whole construction period. Including the drawings submission and approval, drawing control, transmittal and retrieval. Construction schedule can be made by BIM system to supervise effectively the subcontractor to complete the works on time, the supplier to deliver the materials by schedule. 3.1.2 Precast Façade – to be used at units for typical floors, core wall for whole building and all structural elements. It can avoid the serious delay because of the reinforcement worker’s shortage in Hong Kong construction industrial general scenes. 3.1.3 Cellform HX formwork (Origin in England) to be used instead of traditional formwork at soffit slab for whole building. More durable than traditional timber formwork. Reducing the time of changing of the broken timbers. Reducing the time of transportation by manpower due to the timber’s heaviness. Reducing the time of concrete repairing after concreting due to its’ smooth surface. 3.1.4 Security Equipment – High quality HD CCTV shall be provided on tower crane to monitor the whole site day by day. Monitoring routine construction program and preventing theft or person who is not permitted to entrance the site. It can reduce the frequency of incident and extra management time. 3.1.5 Augreen Block Wall Sytem – to be used at all internal, non-structural vertical elements, partitions instead of traditional brick wall. It combines with the acoustic function, fire resistant, high strength, waterproofing features and higher productivity. 3.1.6 Planting – One tower crane to be used for hoisting the materials to appropriate working place from storage area. Usage time from difference trade shall be arranged by our site agent or foreman 3.1.7 Construction Cycle – 5 days cycle selected. Please see Chapter 3.6 3.1.8 Scaffolding – Adopt the metal scaffolding to save the repairing time. BNV6102 Bid Strategy group project Group 6 Page 35 3.2 Site Logistics Site logistic is also a very important component in a construction industry in terms of time control. It is an immense difficulty to deliver the bulky quantities of material to a limitation space of site at one time. So a good and comprehensive planning on site logistic is a most appropriate way to solve the logistic problems. The material transportation mostly divided into difference ways. One is the horizontal and the other one is vertical, hoist by manpower or machines. To catering for this residential building, one tower crane is provided for covering whole site. All materials are to be placed at the podium floor level. Externally transport to site entrance and internally transport to podium floor level. The following chart showing the allocation of using the tower crane by difference trade on concreting stage.

Construct steel frame structure – supply and install steel structure in one sub-contractor that it would be more efficiency on the program of the works. 2. Construct core wall for lift – make sure the size of lift can functional after the installation of lift supplier. 3. Construct Precast Facade – installation procedure or method statement must be submitted and approval before commencement of the works. 4. Provide the fire resisting paint work – after completion the steel works it should be paint in fire resisting paint that has the requirement in our contract. 5. E&M works – material submission and approval, supply and install during after the structure and completion date. 6. Trades works-material submission and approval, supply and install should be follow to general notes. Whole buildings uses the wet concrete, platform construction methods according to traditional practice, First step install columns, and then formwork, steel works and concreting, in this process propose 5 or 6 days cycle for complete each typical floor. In order to lifting material and formwork, we will build a temporary platform in the lift shaft. From the construction of buildings to the existing building propose build a 3m width of the ramp scaffold for protection. On the other hand, according to the requirements of building regulations need to submit detailed reports for the cantilever slab which design exceed 750mm.

Generally, it shows critical path, milestone date and construction sequence for whole project. For this project, I have prepared the milestone program. Please see the Appendix X. 3.7 Manpower Arrangement To allocate the site staff to be theirs own role and responsibilities at various months. Manpower is neither or a most important thing in any fields. For increasing the efficient and productivity of construction project, it is necessary to make a proper decision on manpower arrangement. The following chart (Figure 3.7.1) showing the most efficiency and valuable on how to distribute the site staff for whole project cycle for carrying out their own duties.
