Building Components

main beam, secondary beam, column, slab (notice the span to hold compression and tension) , vs wind load, gravity load

horizontal members, vertical members

foundation/footing

slab-on-grade foundation (grade level = ground level)

HK commonly use reinforced concrete

substructure 底層結構工程 (below ground)

plinth 底座 (in between)

superstructure 上蓋工程 (visible part above ground)

site formation works 工地平整工程 (Site formation works are performed to prepare a construction site for subsequent works for foundation and superstructure. They generally involve the clearance of construction site, demolition of existing structures, excavation to the design formation and/or basement level, reduction and stabilisation of existing slopes, and associated infrastructure works (which include construction of road, drainage, sewage and water works)

foundation works 地基工程

Excavation 挖掘

piling works 打樁工程

demotion works 清拆工程

staircase, lifts, internal walls

bathroom with sunken slab to prevent leakage

balcony with floor level difference to prevent overflow

AC platform with louver

Fire services (hydrant, hose reel, sprinker, bell, fire extenguisher, e-light)

transformer rooms, water tanks

rooftop: life machine room, lightning, HVAC chiller (air inlet, FS inlet, towngas inlet)

residential framing plan

AHU room (air handling unit / Air inlet) – is the heart of central air conditioning. It collects outside air and room air, removes dust and other particles from the collected air, adjusts the temperature and humidity and then supplies comfortable and refreshing air-conditioned air into the rooms through ducts. Indoor air quality

HVAC (heating, ventilating and air conditioning system) – complete system

Slabs are horizontal surfaces, columns are vertical supports, and beams are horizontal members that bridge the space between columns. Together, they create a stable framework for buildings, ensuring that loads are effectively transferred to the ground.

  1. Design Codes and Standards
  2. Load Considerations = dead load (self-weight of the members), live load (movable) depends on occupancy, seismic load and wind load depends on height
  3. Framing system need to coordinate with architectural and MEP mechanical, electrical and plumbing
  4. Structural Modeling
