Why does a groundworks job get lost between the DPGF, the progress billing and the retention?
A public civil-works contract means a DPGF to price line by line, a progress statement to draw up every month and a retention to track until it's released — and it all ends up on spreadsheets that don't talk to each other. A bill-of-quantities price gets missed, a statement goes out late, an AIPR lapses the day before a job under live traffic, a subcontractor works with nothing recorded. Constrigo brings the tender response, the DPGF, the progress billing, the retention and the certifications together in one place. The site manager reports progress and photos from the field, you approve the statement, and the office pulls up the contract's history in one click.

StripeWhat Constrigo does for this trade
Public tender responses
A public groundworks contract turns on a clear, costed response. Constrigo helps you structure your bid — technical memo, price breakdown, documents to attach — and build the pricing from your bill of quantities. It won't win the tender for you: it gets you to submission with a complete offer, without missing a DPGF line or an administrative document.
DPGF & bill of quantities
On a road or network contract, every item is priced by the line — earthworks by the cubic metre, pipework by the linear metre, asphalt by the tonne. Constrigo builds your DPGF line by line from a bill of unit prices you reuse from one job to the next. You break down each price, keep your library of items up to date and produce consistent pricing without starting from a blank sheet on every tender.
Progress billing & retention
A civil-works contract is invoiced monthly, as the job advances. Constrigo draws up your progress statements package by package — earthworks, networks, roadway, finishes — applies the retention to each amount and works out the net due. The retention is tracked job by job until it's released, so at any moment you know what's invoiced, what's collected and what the client is still holding back.
Site journal & photos
On earthworks or a network install, one day of bad weather stops everything. The site journal logs the day's weather, the real progress and what rain or frost brought to a halt, with photos to back it up. The site manager fills it in from the field, and you keep a dated record — handy for justifying a delay to the client or documenting a trench inspection before backfilling.
Team scheduling & certifications
An expired AIPR or plant-operator CACES should never be discovered in front of an open trench. Constrigo records each worker's AIPR authorizations, plant CACES and safety qualifications, and flags a clash the moment a job needs a certification no one available holds — or one about to expire. The schedule shows which crew is on which job and flags overlapping slots before they block work near the networks.
Subcontracting & supplier portal
A groundworks job often brings in subcontractors — surfacing, road signage, a specialist pipe-layer. Constrigo keeps a record of your subcontractors and opens a supplier portal for them to share documents and track their work on the contract. You know who does what and where each subcontracted package stands, without chasing emails and documents scattered across several parties.
Job profitability
A contract won at the right price can turn against you on the ground — earthworks harder than expected, plant hours running away, a DPGF item priced too low. Constrigo sets what you invoiced through progress billing against what the job actually cost — hours, plant, materials, subcontracting — and works out the margin per contract. You spot the job going over before close-out and refine your unit prices for the next tender.
Before and after Constrigo for a civil-works contractor
The same groundworks contract — DPGF, progress billing, retention, certifications — on spreadsheets, then in Constrigo.
| Without trade software | With Constrigo |
|---|---|
| The DPGF retyped item by item in a spreadsheet, a bill-of-quantities price missed on every tender. | DPGF built line by line from a reusable bill of unit prices. |
| The monthly statement drawn up by hand, sent late, cash flow left waiting. | Monthly progress statements, retention applied and net due worked out. |
| The AIPR authorization expired, found out in front of a trench near the networks. | AIPR and CACES tracked, a clash flagged in the schedule before the crew leaves for site. |
| The surfacing subcontractor who steps in with not a single document recorded. | Subcontractors on record and a supplier portal to share documents and track packages. |
| The retention forgotten in a corner of a spreadsheet, never claimed at release. | Retention tracked job by job until it's released, margin per contract kept in view. |
