Construction Definition and 253 Threads

Construction is a general term meaning the art and science to form objects, systems, or organizations, and comes from Latin constructio (from com- "together" and struere "to pile up") and Old French construction. To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure.
In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure and industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning.
As an industry, construction accounts for more than 10% of global GDP (6-9% in developed countries) and employs around 7% of the global workforce - over 273m people. The output of the global construction industry was worth an estimated $10.8 trillion in 2017.

    Joe previously a civil engineer

    I have studied Buddhist teaching for 25 years and subsequently find physics a pleasure. I like to invent things by bringing together all the knowledge I have accumulated from unique sources and my own memory. A long time ago I invented a machine to turn oxygen into water and although I did not...

    Do you think this is an oil well, water well or what? (Tintype)

    Maybe 1860s - 1870s tintype. Post processed heavily to reveal the image. What do you think they are building? I'm not student or engineer. I'm an archivist. (non-professional) I get lots of old photos and films that need some deciphering, so hope this group can help out.

    B How circular does it need to be?

    The above was part of a conversation on ##\pi## and the implication seems to be that the more accurate the value of ##\pi## in our calculations in an engineering context, the more circular our construction. Questions: 1. Is this true? More accurate values of ##\pi## allow for construction of...

    How to construct a periodic function ## f ## with period ## 4 ##?

    On the book, it says, "Let ## f ## be defined by ## f(4n)=f(4n+1)=0, f(4n+2)=2 ## and ## f(4n+3)=1 ##, for all integers ## n ##". (Other answers are possible). But I don't understand, how does this work in the problem? I know that it must has something to do with the period, which is ## 4 ## in...

    Sustainable building with earth, corrugated galvanised iron and rebars

    There are lot of people on the Internet trying to build a cheap and sustainable house. Inspired by them I came with the idea of building external walls of Corrugated galvanised iron (CGI) and rebars and fill them with earth / sand. The basic element of the wall structure is this rebar trapeze...

    Quantum Readable sources for C*-algebras and GNS construction?

    It is there a gentle introduction to C*-algebras and the GNS construction that is readable for physicists? You know, a text with an emphasis on QM that is formal enough to not be sloppy but not too much as to require a Ph.D in functional analysis to be read.
