East Coast Help Point installation
19 TDM two-button GSM Help Points supplied, installed, tested and commissioned across ten stations, wall and post mounted, with station handover packs.
Survey and Design
The scope fixed before installation starts.
Station systems survey and design: site surveys that establish what is there, and reference and detailed design that sets out what changes.
Dilapidation and intrusive surveys, pre-installation audits and scope validation.
Survey and DesignReference and detailed design, general arrangements, schematics and risk assessments.
Survey and DesignRequirement
The existing estate, recorded before it changes
Before any station system is replaced or added, the existing estate, the site constraints and the migration path have to be recorded and designed against.
TDM surveys the existing estate before anything changes, then designs the change against it. On a CCTV migration programme, dilapidation surveys and pre-installation audits found a mixed analogue and IP estate, and the design carried the retained analogue cameras onto IP recording through new encoders.
Survey
What the survey records
TDM’s surveys record the locations of existing and proposed equipment, migration requirements, data connectivity, electrical capacity, containment, signal sighting, GSM coverage for Help Points and access restrictions.
Design
A reference design, then the detail
TDM designs in two stages. A reference design fixes the scope and principles. A detailed design then produces the general arrangements, schematics, calculations, labelling and designer risk assessments the installation needs.
Design runs to the stage the scheme needs, from GRIP4 and GRIP5 SISS design to ES5 telecoms design, with acoustic modelling where PA is involved.
