Skanska has been working with technology companies to develop a prototype robotic platform that can navigate construction sites and carry out specific, pre-programmed activities.

The Collaborative On-Site Construction Robot (COSCR) project is an Innovate UK project which brings together factory automation and robotics expertise from HAL Robotics, ABB and InnoTecUK, together with project management expertise from BRE, site access and productisation experience from Skyjack and construction industry insight from Skanska.

The COSCR platform comprises a robust mobile base, site sensing technology and BIM-linked software systems that enable it to navigate safely and accurately around a construction site.


It can be operated manually or autonomously. In manual mode, an operator uses a controller to move the robot around the site. In autonomous mode, the robot uses its onboard sensors, as well as maps derived directly from BIM (building information modelling) data, to navigate itself safely around the site and perform tasks that have been scheduled by the user.

It has been developed to specific size and weight constraints to maximise its potential to access the tightest corners of any site. The platform is tracked, which enhances the manoeuvrability, and features a telescopic mast fitted with a robotic arm, enabling it to reach heights of up to 4.2 metres.

The robot is designed to deliver construction activities that may otherwise be repetitive or potentially hazardous, such as drilling at height. As a first proof of concept, the project focused on a drilling and anchor insertion application which was trialled on a live construction site at Skanska’s Featherstone Building project in central London.
