Crime scenes have their own story to tell

London is home to almost nine million people across 32 boroughs. We use every possible means to keep them safe and bring criminals to justice. The Met’s Computer Aided Modelling Bureau provides invaluable support to high profile criminal investigations and police operations. Our team`s made up of experts in a broad range of sophisticated survey technologies, who specialise in producing 2D plans and 3D computer models to reconstruct and analyse crime scenes. The cases are high profile, the work is demanding, but it’s an incredibly rewarding role.

This is a real opportunity for you, whether you’re a surveying, geomatics, reality capture or CAD professional. You’ll provide 2D & 3D reconstructions of the built environment — including accurate measurement recording of crime scenes and detailed geospatial analysis in order to support police operations and criminal cases going to trial.

It will see you attend scenes of crime using CAMB’s technical response vehicles to capture and process measured survey and laser scan data. You’ll produce accurate drawings or models of these for analysis and presentation of scenes of crime. You will manage and coordinate projects and contractors. Identifying requirements, writing specifications and defining the brief before overseeing the project to completion.

The role will call on your integrity, professionalism, resilience and can-do approach. You’ll need to be comfortable working flexibly, at short notice and on call in an operational context when required, and confident in driving work vehicles in central London during rush hour.

On the technical side, you’ll have a background in surveying or engineering/metrology and need to be competent in using CAD software to produce site and floor plans. You will hold an appropriate qualification and be keen to develop your skills and explore advances in 3D modelling, CAD, laser scanning and photogrammetry technologies so that you can develop innovative solutions.

It’s a unique chance not only to progress your career, but to directly support police operations. The sensitivity and often high profile nature of the work means you’ll need to pass security vetting before taking up the post.

Job Role:

Responsible for the provision of 2D & 3D reconstructions of the built environment, which includes accurate measurement of crime scenes and providing detailed geospatial analysis to support police operations, criminal cases going to trial and production of information to support the management of the Met’s property estate. The role holder will establish efficient and effective geomatics, mapping, Computer Aided Design, reality capture and laser scanning processes and workflows to produce 2D plans and detailed 3D models from real world survey data. You will provide expertise in these areas to assist in investigations and present technical information for use in court. This position requires the ability to work both independently and collaboratively, ensuring the smooth and timely delivery of generated products. To respond to operational requirements the role holder will be required to confidently drive work vehicles (including a van and 4x4 vehicle) across central London in rush hour traffic, and outside the capital on occasion. The role also involves viewing potentially disturbing scenes and material when required. The role holder must also be willing to provide out of hours on-call support on a rotational basis, and will need to pass security vetting before taking up the post to reflect the sensitivity and often high profile nature of the work.

Key Responsibilities:

  • Attend scenes of crime using CAMB’s technical response vehicles to capture and process measured survey and laser scan data.
  • Ensure all equipment used is well-maintained and used in accordance with manufacturers’ instructions.
  • Deliver high definition 3D surveying, mapping and modelling services on time, ensuring products are accurate, fit for purpose and provide best value.
  • Utilise laser scan data capture and 3D digital modelling techniques to analyse and represent scenes of crime, to an appropriate level of detail.
  • Ensure work complies with statutory and legislative requirements, contractual obligations and relevant policies and standards.
  • Draw upon professional geomatics/3D modelling/Computer Aided Design/laser scanning knowledge and experience to maintain standards and develop procedures allowing consistency of methods and best practice, ensuring all outputs are compliant and within appropriate tolerances.
  • Manage and coordinate projects, determine scope, identify requirements and write specifications as required. Define a detailed brief and oversee projects to successful completion.
  • Manage external contractors / supply chain to deliver outsourced geomatics, geospatial and modelling services to provide effective, efficient and best value solutions for operational policing.
  • Support investigation teams, forensic specialists, and other experts, helping the interpretation, understanding and incorporation of complex data and forensic evidence within a spatial context. (Note: this may include supporting the reconstruction of ‘bullet trajectories’, assessing ‘lines of sight’ and mapping blood spatter etc.)
  • Attend case conferences and advise police officers, barristers and the Crown Prosecution Service as a technical specialist, and when required explain your work as an expert in court.
  • Comply with all health and safety policies and procedures and undertake all required training. Identify hazards and write/review risk assessments as required. Promote a positive health, safety and wellbeing culture and raise any health and safety concerns.
  • Maintain good physical, data and cyber security awareness. Comply with all security processes and procedures (including all physical, data and IT security requirements).
