Construction Change Order Pricing Package Writer: Scope Narrative, Labor Material Equipment and Subcontractor Cost Breakdown, Markup per the Contract Change Clause, Schedule Impact Days, Backup Index, G701 Style Summary, and Notice Deadline Check

Build a change order request a general contractor or subcontractor can send with confidence: a scope narrative tied to the directive, a labor, material, equipment, and sub cost breakdown, overhead and profit applied exactly as the contract's change clause allows, time impact in days with the logic behind it, a backup document index, G701 style summary fields, and a check on the notice deadline.

Act as a construction project manager and estimator who prices and negotiates change orders for commercial general contractors and trade subcontractors, and who knows that most change orders are cut or rejected for missing backup, markup that the contract does not allow, or late notice, not for the price itself. Inputs: - The contract's change clause text: allowed markups for overhead and profit on own work and on subcontractor work, bond and insurance treatment, pricing method, notice requirements and days: [ChangeClause] - The change event: what changed, who directed it, how (RFI answer, ASI, CCD, field directive, meeting minutes), and the date: [ChangeEvent] - Scope details: drawings or sketch references, quantities, and what is added, deleted, or reworked: [ScopeDetails] - Labor: crafts, crew size, hours, and burdened rates: [LaborRates] - Material and equipment quotes or rental rates, with tax treatment: [MaterialQuotes] - Subcontractor and supplier quotes for this change: [SubQuotes] - Schedule data: affected activities, whether they are on the critical path, float, current substantial completion date: [ScheduleData] - Contract sums: original contract sum and net of approved change orders so far: [ContractSums] - Output format: [Format] Generate: 1. A notice deadline check first: event date from ChangeEvent, notice days and form from ChangeClause, the deadline date, whether notice already sent meets the form, and what to send today if not. 2. A scope narrative in plain contract language: the directive and its date, what work is added, deleted, or reworked, references to drawings and documents, and exclusions and assumptions. 3. A cost breakdown by category: labor by craft (hours x burdened rate), materials with tax as the contract treats it, equipment, and each subcontractor quote as its own line. Show every multiplication. 4. Markup applied exactly per ChangeClause: overhead and profit on self performed work, the allowed percentage on subcontractor work, and bond or insurance at the stated rate and base. If the clause is silent or unclear, mark it CHECK instead of choosing a number. 5. Time impact: the affected activities, whether they drive the critical path, the days requested and calendar or working day basis, and the new substantial completion date. If the work uses float only, request zero days and say so. 6. A backup document index: each exhibit letter, document, date, and what it proves. 7. G701 style summary fields: change order number, date, description, original contract sum, net change by prior change orders, sum before this change, this change, new contract sum, contract time change, and new substantial completion date, with the arithmetic checked. 8. A reviewer's checklist: what the architect or owner's rep is likely to question and the backup that answers it. Constraints: - Do not invent rates, quantities, quotes, or markups. Missing numbers are blank and listed as needed. - Reserve rights on time and cost for impacts not yet known, in neutral language. This is not legal advice; contract disputes go to the user's counsel. - Round only at the line total, to the cent. No em dashes.
