). The very simplest shelters, tents, leave no traces. Because of this, what little we can say about very early construction is mostly conjecture and based on what we know about the way nomadic hunter-gatherers and herdsmen in remote areas build shelters today. The absence of metal tools placed limitations on the materials that could be worked, but it was still possible to build quite elaborate stone structures with ingenuity using dry-stone-walling techniques (see the stone structures at Skara Brae

. In all cases of timber structures in these very early cultures, only the very lowest parts of the walls and post-holes are unearthed in archaeological excavations, making reconstruction of the upper parts of these buildings purely conjectural. The most remarkable Neolithic structure in Western Europe is the iconic monument known as Stonehenge, regarded by some archaeologists as displaying methods of timber construction translated into stone. The now ruinous remains include massive sandstone lintels which were located on supporting uprights by means of mortise and tenon joints; the lintels themselves being end-jointed by the use of toggle joints (tongue and groove). There is also evidence of prefabrication of the stonework; the symmetrical geometric arrays of stone clearly indicate that the builders of Stonehenge had mastered sophisticated surveying methods.

). Bricks varied widely in size and format from small bricks that could be lifted in one hand to ones as big as large paving slabs. Rectangular and square bricks were both common. They were laid in virtually every bonding pattern imaginable and used with considerable sophistication. Drawings survive on clay tablets from later periods showing that buildings were set out on brick modules. By 3500 BC, bricks were also being fired and surviving records show a very complex division of labour into separate tasks and trades. Life in general was governed by complex ritual and this extended to rituals for setting-out buildings and moulding the first bricks.

(Luxor) provides one of the finest examples of mud brick construction. Extensive storehouses with mud-brick vaults also survive, all constructed with sloping courses to avoid the need for formwork.

The grandest buildings were constructed in stone, often from massive masonry blocks. The techniques used to move massive blocks used in pyramids and temples have been subject to extensive debate. Some authors have suggested that the larger blocks may not be cut stone but fabricated with concrete.

Technology

Although the Egyptians achieved extraordinary feats of engineering, they appear to have done so with relatively primitive technology. As far as is known they did not use wheels or pulleys. They transported massive stones over great distances using rollers, ropes and sledges hauled by large numbers of slaves. There are no surviving Egyptian manuals so there has been considerable speculation on how stones were lifted to great heights and obelisks erected. Most theories centre on the use of ramps.

which remained the tallest structure in the world for 3800 years (see List of tallest freestanding structures in the world). The engineering problems involved were chiefly to do with the transport of blocks, sometimes over long distances, their movement into location and exact alignment.

The methods used in the construction of the pyramids have been the subject of considerable research and discussion (see: Egyptian pyramid construction techniques

Construction in ancient Greece

The ancient Greeks, like the Egyptians and the Mesopotamians,tended to build most of their common buildings out of mud brick, leaving no record behind them. However very many structures do survive, some of which are in a very good state of repair, although some have been partly reconstructed or re-erected in the modern era.

was mainly restricted to roofing tiles and associated decorations, but these were quite elaborate. Fired bricks were not commonly employed. Very prominent buildings were roofed in stone tiles, which mimicked the form of their terracotta counterparts. While later cultures tended to construct their stone buildings with thin skins of finished stones over rubble cores, the Greeks tended to build out of large cut blocks, joined with metal cramps. This was a slow, expensive and laborious process which limited the number of buildings that could be constructed. The metal cramps often failed through corrosion.

Building structures used a simple beam and column system without vaults or arches, which based strict limits on the spans that could achieved. However, the Greeks did construct Arch Bridge

s, which they built over huge spans. The Romans developed systems of hollow pots for making their domes and sophisticated heating and ventilation systems for their thermal baths. Glass was commonly used in windows.

Organisation of labour

The Romans had trade guilds. Most construction was done by slaves or freed men. The use of slave labour undoubtedly cut costs and was one of the reasons for the scale of some of the structures. The Romans placed a considerable emphasis in building their buildings extremely fast, usually within two years. For very large structures the only way this could be achieved was by the application of vast numbers of workers to the task.

The upper limit of lifting appears to have been about 100 tonnes.

(But Roman techniques, including the use of iron ring-beams, would appear to have been used in the Palatine Chapel at Aachen, c. 800 AD, where it is believed builders from the Langobard Kingdom in northern Italy contributed to the work.

Materials

Most buildings in Northern Europe were constructed of timber until c. 1000 AD. In Southern Europe adobe remained predominant. Brick continued to be manufactured in Italy throughout the period 600-1000 AD but elsewhere the craft of brickmaking had largely disappeared and with it the methods for burning tiles. Roofs were largely thatched. Houses were small and gathered around a large communal hall. Monasticism spread more sophisticated building techniques. The Cistercians may have been responsible for reintroducing brickmaking to the area from Holland, through Denmark and Northern Germany to Poland leading to Backsteingotik. Brick remained the most popular prestige material in these areas throughout the period. Elsewhere buildings were typically in timber or where it could be afforded, stone.

walls and piers is still a major cause for concern.

Design

There were no standard textbooks on building in the Middle Ages. Master craftsmen transferred their knowledge through apprenticeships and from father to son. Trade secrets were closely guarded, as they were the source of a craftsman's livelihood. Drawings only survive from the later period. Parchment was too expensive to be commonly used and paper did not appear until the end of the period. Models were used for designing structures and could be built to large scales. Details were mostly designed at full size on tracing floors, some of which survive.

Labour

In general, medieval buildings were built by paid workers. Unskilled work was done by labourers paid by the day. Skilled craftsmen served apprenticeships or learned their trade from their parents. It is not clear how many women were members of a guild holding a monopoly on a particular trade in a defined area (usually within the town walls). Towns were in general very small by modern standards and dominated by the dwellings of a small number of rich nobles or merchants, and by cathedrals and churches.

in Florence.

Materials

The major breakthroughs in this period were to do with the technology of conversion. Water mills in most of western Europe were used to saw timber and convert trees into planks. Bricks were used in ever increasing quantities. In Italy the brickmakers were organised into guilds although the kilns were mostly in rural areas because of the risk of fire and easy availability of firewood and brickearth. Brickmakers were typically paid by the brick, which gave them an incentive to make them too small. As a result, legislation was laid down regulating the minimum sizes and each town kept measures against which bricks had to be compared. An increasing amount of ironwork was used in roof carpentry for straps and tension members. The iron was fixed using forelock bolts. The screw-threaded bolt (and nut) could be made and are found in clockmaking in this period, but they were labour intensive and thus not used on large structures. Roofing was typically of terracotta roof tiles. In Italy they followed Roman precedents. In northern Europe plain tiles were used. Stone, where available, remained the material of choice for prestige buildings.

Design

The rebirth of the idea of an architect in the Renaissance radically changed the nature of building design. The Renaissance reintroduced the classical style of architecture. Leon Battista Alberti's treatise on architecture raised the subject to a new level, defining architecture as something worthy of study by the aristocracy. Previously it was viewed merely as a technical art, suited only to the artisan. The resulting change in status of architecture and more importantly the architect is key to understanding the changes in the process of design. The Renaissance architect was often an artist (a painter or sculptor) who had little knowledge of building technology but a keen grasp of the rules of classical design. The architect thus had to provide detailed drawings for the craftsmen setting out the disposition of the various parts. This was what we call the process of design, from the Italian word for drawing. Occasionally the architect would get involved in particularly difficult technical problems but the technical side of architecture was mainly left up to the craftsmen. This change in the way buildings were designed had a fundamental difference on the way problems were approached. Where the Medieval craftsmen tended to approach a problem with a technical solution in mind, the Renaissance architect started with an idea of the what the end product needed to look like and then searched around for a way of making it work. This led to extraordinary leaps forward in engineering.

Labour

Labour in the Renaissance was much the same as in the Middle Ages: buildings were built by paid workers. Unskilled work was done by labourers paid by the day. Skilled craftsmen served apprenticeships or learned their trade from their parents. Craftsmen were organized in guild

s which provided a limited form of building regulation in return for members of the guild holding a monopoly on a particular trade in a defined area (usually within the town walls). Towns were in general very small by modern standards and dominated by the dwellings of a small number of rich nobles or merchants and cathedrals and churches.

Technical advances

The wish to return to classical architecture created problems for the Renaissance buildings. The builders did not use concrete and thus comparable vaults and domes had to be replicated in brick or stone. The greatest technical feats were undoubtedly in these areas. The first major breakthrough was Brunelleschi's project for the dome

Dome

of Santa Maria del Fiore

Santa Maria del Fiore

. Brunelleschi managed to devise a way of building a huge dome without formwork, relying instead on the weight of the bricks and the way they were laid to keep them in position and the shape of the dome to keep it standing. The exact way the dome was built is still subject to debate today as it is not possible to take the dome apart to study its construction without destroying it. The dome is a double skin, linked by ribs, with a series of wooden and stone chains around it at intervals to attempt to deal with hoop stresses.

Brunelleschi's dome was completed (up to the base of the lantern) in 1446. Its size was soon surpassed by the dome of St Peter's, built using flying scaffolding supported on the cornices and constructed using two stone shells.

Construction in the seventeenth century

The seventeenth century saw the birth of modern science which would have profound effects on building construction in the centuries to come. The major breakthroughs were towards the end of the century when architect-engineers began to use experimental science to inform the form of their buildings. However it was not until the eighteenth century that engineering theory developed sufficiently to allow sizes of members to be calculated. Seventeenth-century structures relied strongly on experience, rules of thumb and the use of scale models.

Materials and tools

are still in regular use.

Methods

Despite the birth of experimental science, the methods of construction in this period remained largely medieval. The same types of crane that had been used in previous centuries were being still being employed. Flying scaffolds were employed at St Paul's Cathedral, England and in the dome of St Peters, Rome, but otherwise the same types of timber scaffolding that had been in use centuries before were retained. Cranes and scaffolding depended on timber. Complex systems of pulleys allowed comparatively large loads to be lifted, and long ramps were used to haul loads up to the upper parts of buildings.

Construction in the eighteenth century

The eighteenth century saw the development of many the ideas that had been born in the late seventeenth century. The architects and engineers became increasingly professionalised. Experimental science and mathematical methods began increasingly sophisticated and employed in buildings. At the same time the birth of the industrial revolution saw an increase in the size of cities and increase in the pace and quantity of construction.

Materials

The major breakthroughs in this period were in the use of iron (both cast and wrought). Iron columns had been used in Wren's designs for the House of Commons and were used in several early eighteenth-century churches in London, but these supported only galleries. In the second half of the eighteenth century the decreasing costs of iron production allowed the construction of major pieces of iron engineering. The Iron Bridge at Coalbrookdale (1779) is a particularly notable example. Large-scale mill construction required fire-proof buildings and cast iron became increasingly used for columns and beams to carry brick vaults for floors. The Louvre in Paris boasted an early example of a wrought-iron roof. Steel was used in the manufacture of tools but could not be made in sufficient quantities to be used for building.

Brick production increased markedly during this period. Many buildings throughout Europe were built of brick, but they were often coated in lime render, sometimes patterned to look like stone. Brick production itself changed little. Bricks were moulded by hand and fired in kilns no different to those used for centuries before. Terracotta in the form of Coade stone

Construction history as an academic discipline

There is no established academic discipline of construction history but a growing number of researchers and academics are working in this field, including structural engineers, archaeologists, architects, historians of technology and architectural historians. Although the subject has been studied since the Renaissance and there were a number of important studies in the nineteenth century, it largely went out of fashion in the mid-twentieth century. In the last thirty years there has been an enormous increase in interest in this field, which is vital to the growing practice of building conservation.

Early writers on construction history

Nineteenth century studies on construction history

In the nineteenth century, lecturers increasingly illustrated their lectures with images of building techniques used in the past and these type of images increasingly appeared in construction text books, such as Rondelet's. The greatest advances however were made by English and French (and later German) architects attempting to understand, record and analyse Gothic buildings. Typical of this type of writing are the works of Robert Willis in England, Viollet-le-Duc in France and Ungewitter in Germany. None of these however were seeking to suggest that the history of construction represented a new approach to the subject of architectural history. August Choisy was perhaps the first author to seriously attempt to undertake such a study.

The early twentieth century studies of the construction history

Santiago Heurta has suggested that it was modernism, with its emphasis on the employment of new materials, that abruptly ended the interest in construction history that appeared to have been growing in the last few decades of the nineteenth century and the early years of the twentieth. With the advent of concrete and steel frame construction, architects, who had been the chief audience for such studies, were no longer as interested as they had been in understanding traditional construction, which suddenly appeared redundant. Very little was thus published between 1920 and 1950. The revival of interest started in archaeology with the studies of Roman construction in the 1950s, but it was not until the 1980s that construction history began to emerge as an independent field.

The late twentieth century

By the end of the twentieth century, steel and concrete construction were themselves becoming the subject of historical investigation.The Construction History Society was formed in the UK in 1982. It produces the only academic international journal devoted to the subject annually. The First International Congress on Construction History was held in Madrid in 2003. This was followed by the Second International Congress in 2006 in Queens College, Cambridge, England and the Third International Congress held in Cottbus in 2009. The Fourth International Congress is scheduled to be held in Paris in 2012
