Built


Imagine you woke up one morning to find everything created by engineers had disappeared. What would you see? No cars, no houses; no phones, bridges or roads. No tunnels under tidal rivers, no soaring skyscrapers. The impact that engineering has had on the human experience is undeniable, but it is also often invisible. In BUILT, structural engineer Roma Agrawal takes a unique look at how construction has evolved from the mud huts of our ancestors to skyscrapers of steel that reach hundreds of metres into the sky. She unearths how engineers have tunnelled through kilometres of solid mountains; how they've bridged across the widest and deepest of rivers, and tamed Nature's precious - and elusive - water resources. She tells vivid tales of the visionaries who created the groundbreaking materials in the Pantheon's record-holding concrete dome and the frame of the record-breaking Eiffel Tower. Through the lens of an engineer, Roma examines tragedies like the collapse of the Quebec Bridge, highlighting the precarious task of ensuring people's safety they hold at every step. With colourful stories of her life-long fascination with buildings - and her own hand-drawn illustrations - Roma reveals the extraordinary secret lives of structures.

Stavět


I obyčejná zeď může být fascinující. Většinu života strávíme ve městech a budovách. Přejíždíme po mostech, čekáme na výtah, dýcháme v podzemních garážích, přivrtáváme poličku nebo se v práci díváme z okna — a stavby i konstrukce, které nám toto všechno umožňují, téměř ani nevnímáme. Stavební inženýrka a popularizátorka Roma Agrawalová přibližuje čtenářům stavební technologie a principy konstrukcí i jejich vývoj od pravěkých hliněných a proutěných chatrčí až po futuristické mrakodrapy a několikakilometrové mosty. Nejde jí přitom o architekturu, ale o odpověď na otázku: Jak to všechno funguje? Se stejnou jasností a vstřícností pak vysvětluje, proč nespadne dřevěná chalupa ani obrovský palác, jak se hloubí podhorský tunel a na co všechno se musí myslet při stavbě mostu. Zároveň vypráví o životech stavitelů a vynálezců, kteří zdokonalovali materiály i konstrukční principy například pro Panteon v Římě nebo Eiffelovu věž v Paříži.
