Start with people and the site, not a product catalogue
Establish the maximum realistic occupancy for each shift and work zone, then map how people could reach a shelter location. On a large industrial site, distance and access can make several local solutions more practical than one remote central structure.
The second layer is the site itself: existing basements or recessed rooms, free plots, utilities, vehicle access, crane access and whether construction or installation can take place while operations continue.
Project options that may need comparison
- a new separate shelter structure on the industrial site;
- a modular or prefabricated solution on a prepared location;
- reconstruction or adaptation of an existing building area where project review supports it;
- a dual-purpose protective structure integrated into new construction or reconstruction;
- multiple smaller shelter locations where access-time and site layout justify them.
Inputs for an early technical review
- people by shift and work zone;
- site plan or a simplified territory layout;
- information on existing rooms being considered;
- possible location for a new structure;
- utilities, access restrictions and installation constraints;
- requirements for autonomy, sanitation, communications and backup power;
- target implementation date and procurement approach.
Build the business case from comparable cost blocks
For management review, separate design, structure, site works, logistics, installation, engineering systems, internal fit-out and explicit risk allowances. Also make indirect impacts visible, such as restricted site access, utility relocation, temporary operational disruption and future maintenance.
