Page 1: Introduction
Many people perceive the construction industry as towering cranes over a city skyline or a pile of bricks and cement in a backyard. In fact the building work itself is only one phase in a development process known as the property lifecycle. Every house, school and road that is developed has its own property lifecycle, in which many different people are involved.
There are many factors that influence the property lifecycle. This study will focus on just one, the issue of sustainable development - development that meets the needs of the present without compromising the needs of future generations. The immense pressure on the world’s environment means measures must be taken today to safeguard natural resources for tomorrow. This is the challenge the construction industry faces.
Davis Langdon & Everest, EC Harris and Gardiner & Theobald are the world’s leading Quantity Surveying practices. The quantity surveyor is the key advisor at all stages of the property lifecycle. The role of the quantity surveyor includes:
- influencing key decisions relating to time, cost and quality
- managing construction finances and contracts
- influencing the design and construction process.
As international organisations with a global influence, Davis Langdon & Everest, EC Harris and Gardiner & Theobald are key players in the sustainable development arena. By putting aside their competitive differences, they are promoting sustainable development to ensure future generations can make key choices about the environment in which they want to live.
Impacts on the environment
The greenhouse effect is caused by trace gases in the atmosphere. Emissions of CO2 are alone responsible for 50% of the global warming effect, resulting mainly from energy used in buildings - heating, lighting and air conditioning. As energy is readily available today at a relatively low cost, it is often taken for granted. Consequently many people fail to think about energy conservation.
Depletion of the ozone layer is mainly due to the use of CFCs which react with the ozone in sunlight. Approximately 10% of the UK’s annual use of CFCs is related to buildings, in refrigerants and foam insulation used in building fabrics. Buildings are created with the aim of providing better environments in which people can live, socialise and work.
