Modular vs capital construction: compare the completed project, not the factory structure with the finished building

First separate construction format from regulatory category

PRU, protective shelter, dual-purpose structure and PMU refer to regulatory or functional project contexts. Modular describes a manufacturing and assembly approach. The project requirement should therefore be established before the construction format is selected.

Where a modular approach can change implementation

• a larger share of structural fabrication can take place off site;
• on-site structural work can be reduced for suitable projects;
• sectional construction can support some capacity-scaling scenarios;
• factory production can make certain fabrication controls easier to organise;
• delivery and crane installation become explicit parts of project planning.

Why capital construction can represent a much broader scope

• large total area and multiple functional rooms;
• integration into a school, hospital, residential development or other complex facility;
• foundations, structures, utilities and site reinstatement as one construction project;
• larger design, survey and pre-construction scope;
• more complex access, sanitary, accessibility and operational requirements.

A useful comparison baseline

• same regulatory/project outcome and protective properties;
• same capacity and area definition;
• same source-data and site assumptions;
• same design and survey scope;
• same excavation, foundations, waterproofing or other civil works where required;
• same delivery, crane and installation responsibility;
• same ventilation, power, water and sanitary scope;
• same commissioning, documentation and warranty result.

Published procurement values illustrate scope differences, not a universal winner

Ukrainian public procurement contains examples ranging from product or modular-supply contracts to capital shelter projects valued at tens or hundreds of millions of hryvnias. These figures are useful only after the procurement type and included scope are understood.
