Tour CGI

Tour CGI is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tour CGI rather than just read about it. In short: Tour CGI (formerly known as Logica Tower and CB16 Tower) is an office skyscraper in the Courbevoie commune of the La Défense district in Paris. Completed in 1971 and renovated in 2003, the tower stands at 110 m (361 ft) tall with 32 floors and is the 51st tallest building in Paris.

Key takeaways

Tour CGI belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tour CGI to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tour CGI from memory before moving on to harder problems.

Reference excerpt

Tour CGI (formerly known as Logica Tower and CB16 Tower) is an office skyscraper in the Courbevoie commune of the La Défense district in Paris. Completed in 1971 and renovated in 2003, the tower stands at 110 m (361 ft) tall with 32 floors and is the 51st tallest building in Paris.

History This first-generation tower is surrounded by the Aurore, Europe, CBX, and D2 towers. It underwent asbestos removal and complete restructuring in 2002-2003, followed by a full renovation in 2018-2019. The complex, classified as a High-Rise Building (IGH), offers a total office leasable area of 27,712 m2 (298,000 sq ft). It comprises 26 floors above ground level and 6 basement levels, as well as a technical terrace on the 28th floor. The CB16 complex is certified" HQE – Tertiary Buildings in Operation" and offers a range of state-of-the-art services. Between December 2019 and October 2022, its premises were occupied by CGI as well as by Esset (formerly Foncia IPM). The code name for the tower's location in the La Défense master plan is CB16.

Worked examples

Example 1 — a first encounter with Tour CGI

Start with the simplest possible case. Write down what Tour CGI claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tour CGI before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tour CGI ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tour CGI

In research: Tour CGI appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tour CGI in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tour CGI is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 establishments in France, 20th-century architecture in France, Buildings and structures completed in 2020, so understanding it makes those chapters shorter.
In everyday life: Look for Tour CGI outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Tour CGI in simple terms?

Why does Tour CGI matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Tour CGI?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
