The assessment of the static safety and seismic vulnerability then requires a multidisciplinary and multilevel approach including a deep and accurate preliminary knowledge phase before performing structural analyses. In the present paper, a consolidated knowledge-based procedure is presented and applied to four case studies in Italy. Interest is focused on the knowledge phase, combining critical—historical analysis to in situ architectural, geometrical, structural, material, and geotechnical aspects. The knowledge phase proves to be fundamental in understanding the structural behavior of cultural heritage, with special attention to the determination and analysis of local mechanisms and vulnerability elements and allowing to validate and give reason to numerical results. The conservation of historical—monumental buildings represents a relevant topic in Italy and in all the Mediterranean countries.

Stages of the building processVIDEO ON THE TOPIC: World's MOST Unusual Buildings
The unit Honeycomb Housing Prototype, which Michael Green Architects has developed for a site in Austin, comprises five stories of flat-pack mass-timber construction on a concrete podium.
Chicago-based Skender relies on steel-framed modules for its system, which is self-supporting up to 12 stories. David Baker Associates uses side-by-side diagrams to distinguish work completed in the factory from that performed in the field. In one, the site work is ghosted to highlight the factory scope left , while the other does the reverse right.
Boni Maddison Architects has developed more than units for the formerly homeless on 10 different sites in Vancouver. The projects, which depend on wood-framed volumetric construction, were completed in less than 18 months. For generations, prefabricated housing has had a bad rap. Visions of ticky-tacky buildings in identical rows with no connection to context pushed modular construction to the fringe. But with global population increasing, the middle class rapidly expanding, and household size shrinking, some 2 billion new homes will be needed by the end of the century.
That far outstrips what current construction methods can supply. At the same time, because nobody wants climate-related population attrition to solve the housing problem for us, greenhouse gas emissions from building construction and operation currently 40 percent of global emissions will have to be slashed. Across the housing sector—and the construction industry more broadly—hopes of salvation through prefabrication are surging. These include the scope for technological innovation; the potential for economies of scale; and the ability to deliver projects as much as 80 percent faster, with improved safety and quality control, higher environmental performance, and reduced risk.
And while Katerra may be unique in the degree to which it is taking charge of its supply chain, a thorough engagement across previously siloed project constituents is a hallmark of contemporary prefab. In fact, they were and are able to push the bounds of design and materiality because of these fuller integrations. Integration has also led to the exploration of new tools and techniques, such as 3-D printing and robot-guided construction.
At Katerra, robots perform such tasks as maneuvering large-format sheathing panels onto framed walls, and cutting and fastening them with precision.
Although Katerra and Skender share a faith in the capacity of modular construction to tackle the housing crisis, they take contrasting approaches. Katerra exemplifies a flat-pack strategy, fabricating building elements such as structural frames, cladding panels, and systems- integrated floor, ceiling, and roofing panels, and shipping them as kits of parts to be assembled on-site.
Skender takes a volumetric approach, in which three-dimensional modules of enclosed space are factory built and finished right down to the TV on the wall, in the case of furnished units , and then stacked and connected on-site.
Flat-pack systems typically allow for greater flexibility and customization than volumetric modules, which are constrained by the dimensions that will fit on a truck.
With the exception of student and microhousing, where small unit size and a high degree of standardization are well-suited to volumetric modules, a hybrid of flat-pack and volumetric systems will probably turn out to be optimal, says Michael Green, a principal at MGA.
The project comprises five stories of mass timber modular construction on a concrete podium. The flat-pack portion consists of CLT panels and glulam frames. A panelized factory-built wood facade system and CLT-based composite roofing panels enclose the structure. Within the dwelling units, bathroom, bedroom, and kitchen pods are standardized to be factory built as volumetric modules and craned into place.
Whether flat-pack, volumetric, or hybrid, off-site fabrication of superstructure concurrent with site work, followed by ultra-speedy on-site assembly, shaves months off a project schedule compared with conventional construction.
Skender can produce a fully finished module—including mechanical and electrical systems, finishes and fixtures, cabinets and countertops—of up to square feet in five days, and can stack and bolt into place on-site eight to 12 modules per day. The system, which constitutes a steel moment frame, is self- supporting to about 12 stories.
These include an story, ,square-foot mixed-use building with eight stories of modular housing on top of a site-built concrete podium and parking structure.
From the time the podium is ready until all modular stories are set and bolted in place will take just seven and a half weeks. Joints between the volumes will then be sealed to maintain a continuous air and vapor barrier, a high-performance metal-panel facade will be applied, and cross-unit connections will be completed inside—a couple of months more in total.
The firm designed a prototypical building using wood-framed volumetric construction that could be replicated across multiple sites.
It comprises 52 square-foot units on three stories. Intended to be demountable and relocatable to allow for temporary installations while longer-term plans for a site evolve, the buildings use a space-frame foundation system to save the time—and cost—of extensive site work. As well as shelter, each building provides support services to help residents change the circumstances that led to their homelessness.
Facade accents in yellow highlight common areas such as kitchens, dining and social rooms, and other support spaces. In addition to their rapid response, it might be expected that modular units would also save money.
But Boni reports that these projects came in at costs comparable to site-built. If a one-bedroom apartment, for example, consists of two volumetric modules side by side, configuring the program so that the seam between the two modules is primarily wall rather than the middle of a room, say, or lots of doorways and cross-unit service connections reduces the need for on-site finishing.
Understanding the way units will be built is essential from the outset, as is a prototype before fabrication starts. Clearly distinguishing work to be performed in the factory from work to be completed on-site is another way to keep costs down.
If a drawing contains both types of scope, DBA typically provides side-by-side versions, one graying out the factory work to highlight the on-site scope, and the other doing the reverse.
The resulting scheme for the Urban Village Project consists of a mass-timber system that can be configured to achieve site-specific projects of varying scales, from a single infill building to community-scale developments of 50 units or so, and even projects comprising multiple communities.
Interchangeable facade elements—windows, balconies, and wall panels—generate variety, while their mechanical connections facilitate retrofitting and reuse in a circular supply chain. Shared spaces and resources foster community, and a range of apartment sizes and configurations supports diverse household types and aging in place.
At a minimum, residents subscribe to a monthly rate that includes such essentials as rent, utilities, and maintenance. In addition, they can choose to subscribe to deals on food, media, insurance, transportation, and recreation. The Urban Village Project is now out for feedback and expressions of interest from investors, developers, municipalities, and the public, with a prototype scheduled for later this year.

Through a similarly analytical methodology it introduces students to construction techniques of greater complexity, with an emphasis on architecture as an integrated manifestation of structure, body, skin and building services. Topics include architectural and structural analysis, materials and sections; fire services and safety; hydraulic, mechanical, and electrical systems, and the types and applicability of constructional systems to different architectural expressions. The unit generates an understanding of the integration of structures and services in medium- to large-scale buildings. The vehicle for this is the combined effect of weekly lectures and workshops. Lectures investigate and critically analyse a number of selected buildings highlighting architectural, structural and technical aspects that pertain to different materials and construction techniques.
3.5 Building Elements
Every building project is different, but you still need to tick off essential stages to make it a success. Understand the stages of a building project so you know what you need to do and build it right. Your building project might be quick and simple or complex. It might be an alteration, a renovation or a completely new build. It could be a seaside holiday house or a multi-unit central city apartment building. The size and complexity of the finished build can affect the duration and complexity of the process.
Continuing Education: Modular Construction
Buildings, like all economic products, command a range of unit prices based on their cost of production and their value to the consumer. In aggregate , the total annual value of building construction in the various national economies is substantial. In in the United States , for example, it was about 10 percent of the gross domestic product , a proportion that is roughly applicable for the world economy as a whole. In spite of these large aggregate values, the unit cost of buildings is quite low when compared to other products.

Local communities have adapted for centuries to challenging surroundings, resulting from unforeseen natural hazards. Vernacular architecture often reveals very intelligent responses attuned to the environment. Therefore, the question that emerged was: how did local populations prepare their dwellings to face frequent earthquakes? It was to respond to this gap in knowledge, that the SEISMIC-V research project was instigated, and this interdisciplinary international publication was prepared. The research revealed the existence of a local seismic culture, in terms of reactive or preventive seismic resistant measures, able to survive, if properly maintained, in areas with frequent earthquakes. Fifty international researchers and experts presented case studies from Latin America, the Mediterranean, Eastern and Central Asia and the Himalayas region, with reference to 20 countries, i. This publication brings together 43 contributions, with new perspectives on seismic retrofitting techniques and relevant data, addressing vernacular architecture; an amazing source of knowledge, and to this day, home to 4 billion people.

Two Types of Modular Construction
Floor and wall units are produced off-site in a factory and erected on-site to form robust structures, ideal for all repetitive cellular projects. Panels can include services, windows, doors and finishes. Building envelope panels with factory fitted insulation and decorative cladding can also be used as load-bearing elements. This offers factory quality and accuracy, together with speed of erection on-site. Modules can be brought to site in a variety of forms, ranging from a basic structure to one with all internal and external finishes and services installed, all ready for assembly.
Created to make the multi-unit residential construction industry more efficient, Prescient uses the power of technology to link the discrete disciplines of architectural design, engineering, manufacturing and assembly. Through its proprietary digital thread, Prescient is reducing time, costs and risks across the entire development, construction and operating value chain. Changes the economics of the deal by allowing buildings to be taller without incurring the high cost and schedule penalties of concrete. The Prescient platform is ideally suited for multi-unit buildings up to feet tall. Their technology and digital design is able to build housing much cheaper and much faster and much more efficiently. No matter what all the other team members have done up front, when we get the baton, we have to finish on time and within budget. Having Prescient on the team from day one is one of the primary reasons we always finish in first place. We have converted multiple projects from other structural systems to Prescient for the simple reason that we would not have been able to finish the projects on time and on budget without Prescient on the team.

A building, or edifice, is a structure with a roof and  walls standing more or less permanently in one place, such as a house or factory. To better understand the term building compare the list of nonbuilding structures. Buildings serve several societal needs — primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat a place of comfort and safety and the outside a place that at times may be harsh and harmful.
