Propose ONE concrete cost-saving measure for this project.
Project: K2 - K2
Context (prior verdicts / cited cost docs):
A concrete cost-saving measure for K2 in the Stange skole extension project is to optimize the marking (merking) process for technical systems by reducing the extent and complexity of permanent engraved marking where possible, and instead use durable pre-printed adhesive labels or supplier-marked components. Since the general technical requirements specify extensive engraving and permanent marking for all components, including those above and below ceilings, and full coordination with documentation, this can be costly in labor and materials.

By standardizing label types, using supplier pre-marked equipment, minimizing marking in hard-to-access or low-maintenance areas, and avoiding duplicated markings, the project can reduce marking time and material costs without compromising operational functionality or compliance. Close coordination early in the project between RITB, system integrators, and TE can finalize an efficient marking plan that meets requirements with lower cost.

This measure addresses a specific and detailed area described in the technical requirements and has potential to save substantial costs related to labor time, materials, and rework during installation.

Respond with ONLY a JSON object for a SavingsProposal with keys: project_id, measure, affected_items (list of {code, quantity, unit_cost}), claimed_saving_nok, and optional assumptions.
Each entry in affected_items must restate a cost line as the project's price schedule already carries it: quantity and unit_cost are the unchanged baseline figures, not the reduced quantity or unit cost your measure would produce. The effect of the measure belongs in claimed_saving_nok.
