RUNNING HEAD: CONSTRUCTION MANAGEMENTCONSTRUCTION ACTIVITIES AND THEIR ORDER:INTRODUCTIONThe schedule activities expected to take place are excavation, compaction, reinforcement and concreting, installation of walls, installation of doors and windows, roofing, landscaping activities andfinishes [ CITATION NSW \l 2057 ]. These are discussed below:Excavation: In practice, this is the second stage of the construction process on site and usually comes after site clearing. This is the removal of all loose top soil in order to reach the desired reduced groundlevel of a site. This can include hand excavations or use of excavator. This site in the best suited method of excavation for this particular site would be the use of excavators as the excavation work is extensive [ CITATION NSW \l 2057 ]. Excavation can be done using a variety of machinery i.e. movingand non-moving plant.Compaction: This is the replacement of an appropriate hard material on site that helps improve both the bearing capacity and reduced ground settlement on the site. It could incorporate the excavated material if it is hard but in most cases new hard-core material is usually brought to the site for hard filling. This is done after the foundation has been laid but before the slab concreting. It is normally done by the use of a compacting machine and it is necessary to do it in layers in order to prevent the material from unbulking prematurely which may cause future soil settlement problems.Reinforcement and Concreting: this activity involves fixing the steel reinforcement layers on the surface being concreted and placing a predetermined proportion of cement, sand and coarse aggregate.The finished product, concrete is usually necessary where good compressive and tensile strength is required and where durability is a factor. This is usually done for slabs, beams, columns and shear walls. The steel for use in reinforcing varies as per the load imposed on the building and an overall process of structural design is usually done to determine a suitable ratio of all the quantities that is both economic and sufficient for the overall structural strength.Installation of walls: this is a masonry task of erecting the partitions of a structure. These could be of various material ranging from masonry blocks to timber, glass and concrete. The finished product serves as a partition between two adjacent rooms or separated parts of a single room [ CITATION NSW \l 2057 ]. There are instances where the walls need to be structural walls and these can be cast with concrete either on or off site. The installation process then resembles the process of column erection.Installation of doors and windows: this step usually comes after all the concreting and partitioning work has been done as it necessitates a finished surface or partition. It is among the last of the construction procedures and is only proceeded by the finishing’s stage. Further plastering is usually done before painting over the door and window frames in order to even the surface. This can fall under the carpentry or glazing sub-trade but in rare occasions, these responsibility can be taken up by a steel fabricator.Roofing: this is the installation of a roof and is usually done immediately the beams above the last storey have been set up. This involves erection of wall plates, trusses and roof covers and later the installation of ceilings. This stage can fall under the responsibility of a carpenter or steel fabricator depending on whether the structure has steel or timber trusses. Roofing is important on weatherproofing a house and necessitates special attention and should therefore be constructed before finishings are incorporated and tested beforehand.Finishes: these are all the activities taken after all the structural, partitioning, access and roofing members have been erected and services installed in the structure. They range from basic painting to 1
RUNNING HEAD: CONSTRUCTION MANAGEMENTthe luxurious aesthetic painting coats and surfaces in a building ready for occupation. It is usually the last stage of construction within the structure.Landscaping: these are all the activities embarked on when preparing the sites aesthetic appearance. They include cleaning after the construction wastes, gardening and any block or concrete works that occurs outside the structure being constructed [ CITATION NSW \l 2057 ].SUB-TRADES:Construction projects by default require many complementary professions that include different sub-trades [ CITATION NSW \l 2057 ]. The relevant sub-trades required for this project besides project management and technical consultation teams include: 1. Site establishment (Fencing, site office, services etc.) 2. Excavator 3. Electrician 4. Plumber & Drainer 5. Gasfitter 6. Concreters for both the in situ Concrete slab and pre-cast concrete walls 7. Carpenter for the Structure’s formwork, internal and external fittings, and cladding.8. Steel Fabricator 9. Roofer 10. Glazier for any windows and glass partitions 12. Plasterer for internal linings & ceiling 13. Paver 14. Tile-mason for tiling walls & floors including waterproofing15. Painters16. Carpet Layer.The order of activities is indicated in the Gantt chart below with their corresponding activity write-up in the MS Excel table attached. The Gantt chart below indicated the period of construction for a duration of 12 months commencing on 1st October 2017 and closing on 1st October 2018.2
