8866 3D Scanner SOWRFP 8866 3D Laser Scanner System
Scope of Work
The scope of work shall be finalized upon the selection of the Firm. The respondent’s
submission shall accurately describe the understanding of the objectives and scope of the
requested goods and services as well as provide an outline of the process to implement the
requirements of the Statement of Work.
1.0 Introduction/Background:
The City of Denton (The City) is interested in receiving proposals to contract with a qualified firm
for a FARO 3D Laser Scanner System including all necessary computer, equipment and
software/hardware for crash/crime scene documentation. The City of Denton Police Department
(The Department) uses a combination of documentation tools to record crash and crime scenes.
These methods include still photography, digital laser measuring devices, Total Station, 3D
laser scanner system, standard tape measure and diagramming software.
The Department desires to update its aging equipment to provide better documentation as well
as provide state-of-the-art information for investigations, reconstructions, and court proceedings.
The Department looks to utilize the most updated FARO 3D laser scanner technology to capture
fast, straight forward, and accurate measurements and imaging of crash and crime scenes.
2.0 Objectives:
The City is seeking to replace the aging FARO 3D laser scanner system that is rapid, user-
friendly, and highly precise to efficiently record of crash and crime scenes for total evidence
recording while enhancing citizen, officer, and investigator safety. The objectives of this 3D laser
scanner system are:
• Provide officers and investigators a portable way to capture accurate details of a
scene for accident investigation and crime scene reconstruction.
• Record scenes to permit officers and investigators to create defined 3D models
of scene for later analysis and case presentation.
• Allow for the extraction of exact measurements or the creation of 3D simulations
of accidents and crimes for use in reconstructive analysis and courtroom
proceedings.
3.0 Scope of Work:
The new FARO 3D laser scanner system must have the ability to perform tracking and 3D
rendering of crash and crime scenes that vary in accessibility and conditions, including streets
and highways, residential and commercial buildings, confined spaces, and rural locations such
as fields, parks, or wooded and undeveloped areas. The rendering of scene locations by a 3D

laser scanner system must be able to be performed in varying lighting and weather conditions,
such as day, night, dusk, dawn, rain, and direct sunlight. For all of the aforementioned
scenarios, the rendering must be accurate and performed in an expedited manner in order to
capture the full 3D data set of a scene prior to the deterioration of evidence, or so that a
location, such as an intersection or public area, may be reopened to the public. The system
must have the capabilities to generate formalized diagrams and video renderings of the
processed scene for purposes of reconstruction and court exhibits. Further, the system must be
robust and ruggedized to withstand the elements and rigors of working in outdoor environments.
It must be capable of being transported and set up within a short period of time on any particular
crash or crime scene. The system software must be intuitive and user friendly so that officers
and investigators do not need any extensive computer background in order to be trained to use
it efficiently. The system should offer long range, high accuracy 3D pulsed, dual axis
compensated laser scanner with integrated high-resolution digital camera with zoom video and
include lithium-ion batteries and A/C adapter. The total package shall include minimum 5-year
warranty, 5-year service & maintenance contract, technical support, software and software
support and maintenance, on-site training, high-end VR ready laptop or tablet computer, tilt and
turn targets, tripods, and tripod stabilizers.
Vendor minimum capability and qualification criterion includes but is not limited to the following:
The applicant vendor must have at least 3 years of experience in providing 3D laser scanning
systems for use in crash/crime scene modelling and reconstruction. This vendor must offer a 3D
laser scanner system which has a proven track record of admissibility in Texas with no less than
4 cases. Vendor must provide complete information on all cases cited. The proposed scanner
must have undergone a validation study to confirm that the critical angle information computed
by scanning ballistic trajectory rods is accurate. Vendor must provide a copy of all validation
studies cited.
