University of Cambridge: North Range & Corn Exchange

University of Cambridge: North Range & Corn Exchange

About This Project

Cambridge University
 
The North Range of Buildings for the University of Cambridge consists of a new Student Services Centre and replacement examination halls. The work entails a combination of demolition, refurbishment of Grade II listed buildings and construction of a new building.
 
The project relocates several student support functions from across Cambridge into a single, consolidated location, while the replacement examination halls also provide flexible seminar and multi-use space outside of the exams season and complementing the refurbished 250-seat historic lecture theatre.
 
Following detailed dialogue with the university, city planners and Historic England, the original examination halls portal is to be re-used to form the new entrance, in order to preserve a memory of the significance of the site and its function in the evolution of the university.
 
The implementation of the New Museums Site masterplan will improve the surrounding public realm through the demolition of several less significant buildings. This will see the creation of a series of urban courts with better connections to the city and wider university.
 
Survey Requirements
The objective of the monitoring is to:
• Confirm the structural movements are in line with the predicted ground movements
• Ensure any significant movement is identified at an early stage to allow sufficient mitigation measures to be implemented
• Provide evidence which may be used to determine the cause of any damage to third parties
 
The monitoring areas surveyed are:
• The facades of the North Range Campus
• The facades of the Corn Exchange adjacent to the Campus
• Manual monitoring of settlement at low level
 
Survey Specifications
Murphy Surveys Monitoring Division were required to install 75 no. precise wireless tilt sensors for real-time monitoring of the facades of the North Range buildings and the facades of the Corn Exchange building. We were also required to carry out manual settlement monitoring and verification readings of the tilt sensors.
