10 Eco Building Materials Revolutionizing Home Construction
The size of buildings in the commercial, institutional, and industrial market segment ranges from a few hundred to as much as 45, square metres , square feet.
All of these buildings have public access and exit requirements, although their populations may differ considerably in density. The unit costs are generally higher than those for dwellings although those of simple industrial buildings may be lower , and this type includes buildings with the highest unit cost, such as hospitals and laboratories. Residential buildings are fairly static in their function, changing only at long intervals. By contrast, most commercial, institutional, and industrial buildings must respond to fairly rapid changes in their functions, and a degree of flexibility is required in their component systems.
In addition, these buildings are built by contractors who utilize heavy mechanized equipment not only for foundations pile drivers and caisson augers but also for lifting heavy components a wide variety of cranes and hoists. Semimanual machines such as cement finishers, terrazzo grinders, and welding generators are also used, but a large percentage of the work is done manually; the human hand and back remain major instruments of the construction industry , well adapted to the nonrepetitive character of building.
The foundations in these buildings support considerably heavier loads than those of residential buildings. Floor loadings range from to 1, kilograms per square metre to pounds per square foot , and the full range of foundation types is used for them. Spread footings are used, as are pile foundations, which are of two types, bearing and friction.
A bearing pile is a device to transmit the load of the building through a layer of soil too weak to take the load to a stronger layer of soil some distance underground; the pile acts as a column to carry the load down to the bearing stratum. Solid bearing piles were originally made of timber, which is rare today; more commonly they are made of precast concrete , and sometimes steel H-piles are used.
The pile length may be a maximum of about 60 metres feet but is usually much less. The piles are put in place by driving them into the ground with large mechanical hammers. Hollow steel pipes are also driven, and the interiors are excavated and filled with concrete to form bearing piles; sometimes the pipe is withdrawn as the concrete is poured.
An alternative to the bearing pile is the caisson. A round hole is dug to a bearing stratum with a drilling machine and temporarily supported by a steel cylindrical shell. The hole is then filled with concrete poured around a cage of reinforcing bars; and the steel shell may or may not be left in place, depending on the surrounding soil.
The diameter of caissons varies from one to three metres three to 10 feet. The friction pile of wood or concrete is driven into soft soil where there is no harder stratum for bearing beneath the site. The building load is supported by the surface friction between the pile and the soil.
Floating foundations consist of flat reinforced concrete slabs or mats or of reinforced concrete tubs with walls turned up around the edge of the mat to create a larger volume. If these buildings do not have basements , in cold climates insulated concrete or masonry frost walls are placed under all exterior nonbearing walls to keep frost from under the floor slabs.
Reinforced concrete foundation walls for basements must be carefully braced to resist lateral earth pressures. These walls may be built in excavations, poured into wooden forms. Sometimes a wall is created by driving interlocking steel sheet piling into the ground, excavating on the basement side, and pouring a concrete wall against it.
Deeper foundation walls can also be built by the slurry wall method, in which a linear series of closely spaced caissonlike holes are successively drilled, filled with concrete, and allowed to harden; the spaces between are excavated by special clamshell buckets and also filled with concrete.
During the excavation and drilling operations, the holes are filled with a high-density liquid slurry , which braces the excavation against collapse but still permits extraction of excavated material.
Finally, the basement is dug adjoining the wall, and the wall is braced against earth pressure. The structures of these buildings are mostly skeleton frames of various types, because of the larger spans their users require and the need for future flexibility. Timber is used, but on a much-reduced scale compared to residential buildings and primarily in regions where timber is readily available.
The public nature of commercial and institutional buildings and the hazards of industrial buildings generally require that they be of noncombustible construction, and this largely excludes the use of light timber frames. Heavy timber construction can be used where the least dimensions of the members exceed 14 centimetres 5. Because most harvested trees are fairly small, it is difficult to obtain solid heavy timbers, and most large shapes are made up by glue laminating smaller pieces. Skeletons of glue-laminated beams and columns, joined by metal connectors, can span 30 to 35 metres to feet.
Heavy decking made of tongue-and-groove planks up to 9. Steel is a major structural material in these buildings. It is a strong and stiff material and yet relatively inexpensive, and it can be quickly fabricated and erected, which saves construction time.
Nearly all structural steel—including sheets, round or square bars, tubes, angles, channels, and I beam or wide flange shapes—is formed by the hot-rolling process.
Steel roof and floor deck panels are fabricated from sheet metal by further cold-rolling into corrugated profiles four to eight centimetres 1. They are usually welded to the supporting steel members and can span up to 4.
The lightest and most efficient structural shape is the bar or open web joist , a standard truss made with angles for the top and bottom chords, joined by welding to a web made of a continuous bent rod.
It is used almost exclusively to support roofs and can span up to 45 metres feet. The standard rolled shapes are frequently used as beams and columns , the wide flange, or W shape, being the most common. The widely separated flanges give it the best profile for resisting the bending action of beams or the buckling action of columns. W shapes are made in various depths and can span up to 30 metres feet.
Where steel beams support concrete floor slabs poured onto a metal deck, they can be made to act compositely with the concrete, resulting in considerable economies in the beam sizes.
The connections of steel shapes are of two types: those made in the workshop and those made at the building site.
Shop connections are usually welded, and site or field connections are usually made with bolts due to the greater labour costs and difficulties of quality control in field welding. Steel columns are joined to foundations with base plates welded to the columns and held by anchor bolts embedded in the concrete.
The erection of steel frames at the building site can proceed very rapidly, because all the pieces can be handled by cranes and all the bolted connections made swiftly by workers with hand-held wrenches. A large proportion of steel structures are built as prefabricated, pre-engineered metal buildings, which are usually for one-story industrial and commercial uses. They are manufactured by companies that specialize in making such buildings of standard steel components—usually rigid steel bents or light trusses—which are assembled into frames and enclosed with corrugated metal siding.
The configurations can be adapted to the needs of individual users. The metal building industry is a rare example of a successful application of prefabrication techniques in the construction industry in the United States , where its products are ubiquitous in the suburban and rural landscape.

Low-rise commercial, institutional, and industrial buildings
Low-rise residential buildings include the smallest buildings produced in large quantities. Other examples include the urban row house and walk-up apartment buildings. Typically these forms have relatively low unit costs because of the limited purchasing power of their owners. The demand for this type of housing has a wide geographic distribution, and therefore most are built by small local contractors using relatively few large machines mostly for earth moving and large amounts of manual labour at the building site.

Framing , in construction , is the fitting together of pieces to give a structure support and shape. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building , masonry , rammed earth , adobe , etc. Building framing is divided into two broad categories,  heavy-frame construction heavy framing if the vertical supports are few and heavy such as in timber framing , pole building framing , or steel framing ; or light-frame construction light-framing if the supports are more numerous and smaller, such as balloon, platform, or light-steel framing. Light-frame construction using standardized dimensional lumber has become the dominant construction method in North America and Australia due to the economy of the method; use of minimal structural material allows builders to enclose a large area at minimal cost while achieving a wide variety of architectural styles. Modern light-frame structures usually gain strength from rigid panels plywood and other plywood-like composites such as oriented strand board OSB used to form all or part of wall sections , but until recently carpenters employed various forms of diagonal bracing to stabilize walls.
