Building Morphology Factors

INTRODUCTION

Building Construction process comprises with many stages.

They basically consist of two parts Pre Construction Post Construction

The Designing process of a building project belongs to the Pre construction stage.

Considering about the Design Morphology Factors comes under this Designing stage.

INTRODUCTION (CONT…)Cost of Construction changes in a rapid manner due to many reasons.

Therefore a proper analysis of Building Morphology Factors are essential to reduce cost of Construction.

This presentation is aimed at understanding what the Design Morphology 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.

BUILDING MORPHOLOGY FACTORS

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

SHAPE AND SIZEShape and Size are interrelated factors.

Both relates with the floor space required by the client.

Research has showed that SQUARE shape is the most cost effective shape.

When designing the shape the ORIENTATION, PROXMITY and SIMILARITY factors must be concerned.

If the new building is in a similar shape as the existing buildings, placing the building in the correct orientation and proximity becomes easy.

STOREY HEIGHT

Service integration must be concerned.

For example;Air conditioning

Fire fighting system

Electrical lighting

Telecommunication systems

If storey height is not decided according to service integration requirement;

Problems occur during installation

Service lines will be installed in an irregular manner.

Proper height must be selected during designing.

TOTAL HEIGHT

Directly connects with the number of storey and storey height.

Higher the building goes;

Stronger the structure should be.Workers, equipment, material etc must be transported continuously to upper floors. More scaffolding requirement.

RESULT

More Financial

Requirement

NUMBER OF STOREY

Must design to the required number only.

Over designing could result in a stronger structure.

If designed correctly, can avoid expensive foundation types.

GROUPING BUILDING

Two methods can be used;Vertical Grouping

- Common Walls and Foundations

Horizontal Grouping

- Common Roofs

Can be used in Building complexes like Apartment buildings.

Another advantage is reduction of circulation spaces and service cores.

When grouped buildings can share circulation spaces and service cores.

ANALYSIS AND RECOMMENDATIONS

SHAPE and SIZE

Designed by UDA designers.

Shape Designed due to Architectural Influence.

Office areas are located on either side of the vertical circulation area.


Recommendation on SHAPE and SIZE

If built in square shape, spaces on either side of the vertical circulation space could be used.

It increases the efficiency of land usage.

Land value is very high.

Design Efficiency Calculation

Floor area of H-shaped building = 2744.28 m2

Floor area if designed as a square shape = 3528.36 m2

Wastage of Floor Area = 784.08 m2



If the building is built without changing the required floor area land area could have been saved.

Design Efficiency Calculation

Perimeter of the H-shaped building = 1039.36 ft.

Perimeter if designed as a square shape = 692.82 ft

Design efficiency = (1039.36 – 692.82) x 100 = 50.02%

692.82

Square shape is 50.02% more effective.



The 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 been easy.

Since the shape is different the main parts of the building faces east and west.

Therefore the heat gain through direct sun light is more and uncomfortable.


HEIGHT of the Building

Storey 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 ducting for A/C, and other services.

Comprising with 14 storeys.

ANALYSIS AND RECOMMENDATIONSRecommendation on HEIGHT

The 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.

ANALYSIS AND RECOMMENDATIONSGROUPING BUILDINGS

New building is constructed few feet away from the existing main building.

At the designing stage it was decided to group the buildings.

But later it was decided not to due to heavy demolition work of the existing building.

Recommendation on GROUPING BUILDINGS

Grouping buildings could have reduced the circulation space needed for the new building.

DESIGN ECONOMICS & COST PLANNING

Design economics helps us to understand the best cost effective way proceed with the construction.

Discussion between construction professionals prior the construction helps them to understand these cost effective way.

Each construction has its own cost effective ways.

To understand these ways Building Morphology Factors can be used.

Concerning about Morphology factors during designing stage is very important.

CONCLUSION

The designing stage of a building project is the best stage to reduce unnecessary costs of the project.

Building Morphology Factors are the key to understand the ways of reducing unnecessary costs.

Shape, Size, Storey height, Total height, Grouping factors can be analyzed carefully to make a project cost effective.

Therefore a proper knowledge on Building Morphology is necessary for construction professionals.
