Capability Brown - proof that engineering for sustainability works

[edit] Introduction

Infrastructure transforms the landscape to the extent that we are still using what was built over 2,000 years ago.

Transforming the landscape was a feature of the English Landscape Movement of the 18th century, when Capability Brown and others were in the right place at the right time to create a legacy that is still enjoyed by millions today.

The movement is an example of how civil engineering can be defined by eras triggered by policy, technology or the environment. For example, the River Navigation Acts (1651-1850), Turnpike Trusts (1707 - 1888), canals (1763-1790), railways (1821-1867), national grid (1901-1938), and motorways (1958-1996).

This is in addition to an ongoing need for other major infrastructure projects, including water supply and sanitation, harbours, airports, flood control and sea defences.

[edit] Project characteristics

The characteristics of these projects are that through adaption and replacement, they can last more than one, possibly more than several, generations.

Usually they are:

Creating a resilient, sustainable infrastructure requires an understanding of how it was built and maintained over several generations of civil engineers using different materials, processes and design principles.

[edit] Transforming the landscape

The legacy left by Capability Brown and his peers was a result of a combination of social, economic, financial, scientific, agricultural and political change that could be regarded as the start of the modern era.

  • The Scientific Revolution (16th – 18th century) marked the emergence of modern science due to developments in mathematics, physics, astronomy, biology and chemistry underpinning engineering practice.
  • The Age of Enlightenment (17th – 18th century) was a philosophical movement advocating freedom, democracy and reason as the primary values of society which resulted in a decline in the influence of the church, government reformation and greater rights for the common people and a rise of the professional class – a precursor to the professional institutions.
  • The Bill of Rights (1689) created a constitutional monarchy in England guaranteeing freedom of speech and freely-elected MPs from landowners.
  • The formation of the Bank of England in 1694 to raise funds for government and to issue notes to promote the public good and benefit of the people by maintaining monetary and financial stability.
  • The Enclosure Acts (1730 – 1780) were a precursor to improvements in agriculture, which together with trade expansion into North America and Caribbean, created wealth leading to social and political changes and increased land ownership.
  • The Agricultural Revolution (1700 -1850) improved land use (land conversion, drainage and reclamation), land governance (enclosure, increase in farm size), agricultural processes (crop rotation, selective breeding) and, with improved transport (turnpikes, canals, river navigation) and markets (tariff, toll and custom free), supported a doubling in population during the 18th century.

The confidence, prosperity and political stability of the 18th century associated with the increase in land ownership led to a demand for significant engineering works to transform the landscape.

[edit] The impact of Capability Brown

Capability Brown was an engineer, an architect and a landscape architect who was responsible for transforming over 250 estates during that period using a signature style of a serpentine lake surrounded by pasture, woodland and parkland.

Sites where Capability Brown is known or thought to have worked in the UK include Blenheim Palace, Harewood House, Buckingham Palace, Cliveden and Dunham Massey.

Traditional methods of construction practice and tools, known since the Roman times, were used together with contractual procedures that still exist today to undertake major earthworks, earth dams, drainage, water courses and roads, which, at the time, probably exceeded all other engineering works.

Brown’s vision was to create a landscape to provide for every need of the ‘great house’, which had to cohere, look elegant and be fit for the owner, the poet and the painter; that is, it had to meet the principles of modern designfit for purpose, aesthetics and sustainable.

This is evident in that the estates have created areas of genetic diversity and biodiversity, regulated local climate, water quality and flow, and provided a sense of place and history.

[edit] What we can learn from past achievements

Engineering the landscape by generations of civil engineers highlights the need to place engineering in context to understand the outcomes so that the legacy created is resilient with a sustainable future that can be adapted to change.
