The 3D concrete printing (3DCP) enables automated, formwork-free construction, but facility management (FM) requirements are rarely considered during asset design and handover. This creates a gap between how 3DCP structures are designed and printed and how they will be maintained throughout their service life. This study develops a Lifecycle-Oriented Facility Management (LOFM) framework to address this gap by integrating FM considerations into the design and printing stages of 3DCP. A structured literature review cross-maps ISO 41001 and EN 15221 with research on 3 DCP durability, sensing, design, and digital-twin applications, identifying five LOFM dimensions: maintainability, durability, accessibility, adaptability, and digital integration. These dimensions are translated into a quantitative decision framework covering 3DCP condition, FM requirements, monitoring systems, deterioration, intervention, repair, and lifecycle cost. A parameterised daily-step Monte Carlo model is demonstrated over a synthetic 25-y ear service life using 5,000 paired simulations. Under the stated assumptions, LOFM produces a mean normalized lifecycle cost of 2.19, compared with 3.19 for conventional FM, representing a 31.3% reduction in the simulated normalized lifecycle cost under t h e baseline assumptions. The probability of at least one unplanned reactive repair is 0.52% under LOFM, compared with 10.24% under conventional FM. However, sensitivity analysis shows that the economic benefit is conditional on key assumptions; increasing s ensor/platform cost five-fold reduces the simulated advantage to −2.0%. When change in Lifecycle Cost, Δ L CC > 0, LOFM is economically favourable; when Δ L CC ≤ 0, the assumptions or LOFM provisions should be reassessed. The framework therefore provides a practical pathway for translating 3DCP characteristics into decisions on access, inspection, monitoring, maintenance, digital handover, and lifecycle cost. Given the limited availability of long -
term, asset-l evel 3DCP data, these results are interpreted as scenario-based estimates rather than field -v alidated predictions. Overall, LOFM provides a design-stage, testable framework for making 3DCP structures not only printable, but also maintainable and economically manageable throughout their lifecycle.
