Morphology factors

  1. 1. Building Morphology Factors
  2. 2. Building Construction process comprises with many stages.They basically consist of two parts  Pre Construction  Post ConstructionThe Designing process of a building project belongs to the Preconstruction stage.Considering about the Design Morphology Factors comesunder this Designing stage.
  3. 3. Cost of Construction changes in a rapid manner due to manyreasons.Therefore a proper analysis of Building Morphology Factors areessential to reduce cost of Construction.This presentation is aimed at understanding what the DesignMorphology Factors are.This discusses about; What the Morphology Factors are. A practical example on implementing Morphology Factors. Analysis and Recommendations of alternatives Designs using Morphology Factors. Impact of Morphology Factors on Cost of Construction.
  4. 4. Main design Morphology Factors that are considered are; Shape of the building – Orientation, Proximity and Similarity factors Size of the building Storey height Total height of the building Number of storey Grouping Buildings – Orientation, Proximity and Similarity factors
  5. 5. Shape and Size are interrelated factors.Both relates with the floor space required by the client.Research has showed that SQUARE shape is the most costeffective shape.When designing the shape the ORIENTATION, PROXMITYand SIMILARITY factors must be concerned.If the new building is in a similar shape as the existingbuildings, placing the building in the correct orientation andproximity becomes easy.
  6. 6. Service integration must be concerned.For example; Air conditioning Fire fighting system Electrical lighting Telecommunication systemsIf storey height is not decided according to service integrationrequirement; Problems occur during installation Service lines will be installed in an irregular manner.Proper height must be selected during designing.
  7. 7. Directly connects with the number of storey and storey height.Higher the building goes; Stronger the structure should be. Workers, equipment, More material etc must be RESULT Financial transported continuously to Requirement upper floors. More scaffolding requirement.
  8. 8. Must design to the required number only.Over designing could result in a stronger structure.If designed correctly, can avoid expensive foundation types.
  9. 9. Two methods can be used; Vertical Grouping - Common Walls and Foundations Horizontal Grouping - Common RoofsCan be used in Building complexes like Apartment buildings.Another advantage is reduction of circulation spaces andservice cores.When grouped buildings can share circulation spaces andservice cores.
  10. 10. SHAPE and SIZEDesigned by UDA designers.Shape Designed due toArchitectural Influence.Office areas are located oneither side of the verticalcirculation area.
  11. 11. Recommendation on SHAPE and SIZEIf built in square shape, spaces on either side of the verticalcirculation space could be used.It increases the efficiency of land usage.Land value is very high.Design Efficiency CalculationFloor area of H-shaped building = 2744.28 m2Floor area if designed as a square shape = 3528.36 m2Wastage of Floor Area = 784.08 m2
  12. 12. Recommendation on SHAPE and SIZEIf the building is built without changing the required floor arealand area could have been saved.Design Efficiency CalculationPerimeter of the H-shaped building = 1039.36 ft.Perimeter if designed as a square shape = 692.82 ftDesign efficiency = (1039.36 – 692.82) x 100 = 50.02% 692.82 Square shape is 50.02% more effective.
  13. 13. Recommendation on SHAPE and SIZEThe existing main building has a L shape.If the new building is designed to have the same shape(similarity factor) orientation of the building could have beeneasy.Since the shape is different the main parts of the building faceseast and west.Therefore the heat gain through direct sun light is more anduncomfortable.
  14. 14. HEIGHT of the BuildingStorey height is 3600 mm.Ceiling to be a Lowered 600 mm from the soffit of the slab.Each floor is designed to be constructed with a proper ductingfor A/C, and other services.Comprising with 14 storeys.
  15. 15. Recommendation on HEIGHTThe location has natural ventilation.Natural ventilation method can be easily applied for upper floors.Therefore A/C ducting is not required for upper floors.So storey height can be reduced.It is cost effective because; Reduces Construction cost. Reduces service installation cost. Reduces services maintenance cost.
  16. 16. GROUPING BUILDINGSNew building is constructed few feet away from the existingmain building.At the designing stage it was decided to group the buildings.But later it was decided not to due to heavy demolition work ofthe existing building.Recommendation on GROUPING BUILDINGSGrouping buildings could have reduced the circulation spaceneeded for the new building.
  17. 17. Design economics helps us to understand the best costeffective way proceed with the construction.Discussion between construction professionals prior theconstruction helps them to understand these cost effective way.Each construction has its own cost effective ways.To understand these ways Building Morphology Factors can beused.Concerning about Morphology factors during designing stage isvery important.
  18. 18. The designing stage of a building project is the best stage toreduce unnecessary costs of the project.Building Morphology Factors are the key to understand theways of reducing unnecessary costs.Shape, Size, Storey height, Total height, Grouping factors canbe analyzed carefully to make a project cost effective.Therefore a proper knowledge on Building Morphology isnecessary for construction professionals.
