Welcome to Construction and Environment & Pollution. In this theme, you will learn about the power of the built environment to keep our cities moving in healthy, safe and sustainable ways that don't harm the environment.

Extra Information and Construction and Traffic & Transport – optional

Construction and Active Travel?

Active travel means making journeys by physically active means, like walking or cycling. These are usually short journeys, like walking to the shops or cycling to work. How can construction help us all to travel more actively?

Construction and Urban Planning?

Finding ways to improve cities with cleaner air and safer streets can be achieved by reducing the number of cars that drive into the city. How can construction design congestion zones that limit the access of cars to a city?

Construction and Safety & Security?

Train stations can be some of the busiest places in a city, with commuters, shoppers and tourists all trying to pass through quickly and safely. How can construction design stations that move large crowds of people?
1. Instructions from your Supervisor


We are currently leading a major railway station redesign and upgrade in the city, and part of the crowd management we need to consider is the safe use of escalators by crowds of railway users, particularly at busy times.

Some of the considerations we need to make include accessibility, personal safety, weather-related issues, and other design principles. Escalators need to be installed where they can be accessed by maintenance teams to fix any problems quickly.

It should be recognised that the pattern of escalator usage at stations is different to most other locations where escalators can be found, and this can result in different and additional hazards, particularly where luggage and intensity of use at peak times is involved. It is often the case that the flow capacity of escalators contributes to the overall performance of the station and the train services contained within it. 

Stopping or hesitation by passengers when leaving escalators can create a blockage and cause instant and potentially hazardous ‘backing-up’ situations on the escalator behind. It is therefore crucial to avoid such problems by ensuring the immediate flow and dispersal of passengers away from escalator ends.

Crowds and heavy flows of people have a significant influence on the safe performance of escalators. These aspects in combination with the often unconventional locations and tightly planned spaces associated with train stations contrive to produce a higher risk of incident.

I have a task that needs completing, and I’d really like your help.

I would like you to complete the online form to ensure that our design meets all the requirements for train station escalator design. Make sure to pay attention to detail. 

I’ve included the resources you need to complete the task, including documents, images, videos and templates. They should give you plenty of ideas and information.

Follow the instructions, and when you’re ready, complete your task. All this should take you about 45 minutes.

When you’re finished with your task, you can learn more about the employers, job roles and projects in this area of construction.
