What Is a Project Data Sheet?
A project data sheet is a structured one-page record of a completed project’s technical and commercial facts - client, location, scope, contract value, dates, technologies used, and key quantities. Firms keep one per project so the same verified details can be reused across bids, portfolios, and reference forms without being re-researched each time.
Where a case study tells a story, a data sheet is a reference record. Every field is a fact you will later paste into a proposal, a project reference sheet, or a capability statement - so it is written for reuse, not for reading.
What does a project data sheet include?
Most firms standardize the same fields so projects stay comparable across a library:
- Project name, location, and sector
- Client or contracting authority and your contractual role (prime, subconsultant, JV partner)
- Contract value and duration, with start and completion dates
- Scope summary: two to four sentences on what was delivered
- Key technical parameters: quantities, capacities, standards applied, technologies or systems used
- Outcome metrics: measurable results such as cost, schedule, or performance figures
- Internal notes: personnel assigned, photos or drawing references, and where the source documentation lives
Because it is an internal artifact, a data sheet can hold detail you would trim before showing a client - confidential values, lessons learned, or the exact drawings to pull.
When do you use a project data sheet?
The data sheet is the source record that feeds every outward-facing document:
- Compiling bids and tenders. Proposal writers draw project facts from the data sheet rather than emailing former project managers under deadline.
- Populating reference and fact sheets. A verified data sheet converts in minutes into a project fact sheet for marketing or a reference sheet for procurement.
- Maintaining a track record. A complete set of data sheets is the raw material for a project portfolio and the past-performance section of a capability statement.
Example: a completed project data sheet
A compact record from a fictional engineering firm:
Project: Meridian Wastewater Treatment Plant Upgrade - Bristol, UK Client: Wessex Water (utilities) · Role: Lead design consultant Value: GBP 6.8M · Period: 01/2023 - 09/2025 Scope: Process and civil design for a 45,000 m³/day capacity upgrade, including two new clarifiers and a SCADA control system. Key parameters: 45,000 m³/day capacity · designed to BS EN 12255 · 18% energy reduction achieved Internal: Design lead A. Okafor · drawings in DMS/2023/MER · client approval to use as reference obtained
Data sheet vs. reference sheet vs. fact sheet
The three documents share a core but face different readers. The data sheet is the internal master record; a project reference sheet is its verifiable procurement version with a client referee; a project fact sheet is the polished public summary; and a project summary is the plain-language narrative that introduces any of them. Maintain the data sheet first - the others are generated from it.
Where to get a template
Start from the free project sheet template (Word, Google Docs, PDF) and keep one file per completed project. Or store each project once in the free SUNAGO project reference manager, which generates reference sheets, fact sheets, and portfolios from a single record - update the data, and every document stays current. Build these from your projects automatically - create a free SUNAGO account.
Frequently asked questions
What is the difference between a project data sheet and a project reference sheet?
A project data sheet is an internal record of a project's technical and commercial facts, kept so you can reuse them. A project reference sheet is the external, verifiable version you submit to an evaluator, and it adds a contactable client referee.
Who prepares a project data sheet?
Usually the project manager or bid team completes it at handover, while the details are fresh. Keeping one per completed project builds a library you can draw on for future proposals, portfolios, and prequalification forms.
How long should a project data sheet be?
One page. A data sheet is a structured record, not a case study - capture the facts an evaluator or proposal writer needs, and link out to full documentation if deeper detail is required.
