Propose ONE concrete cost-saving measure for this project. Project: D100 - D100 Context (prior verdicts / cited cost docs): A concrete cost-saving measure based on the D100 operating requirements is to avoid a dedicated (separate) power circuit between the server room and the office floors when the room draws a load of 4,000 W or less. According to Krav 3.3.1—13, a dedicated circuit is required only if the load exceeds 4,000 W, so sharing the existing circuit under this threshold reduces installation costs while still complying with D100. 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.
