HERON for 2D takeoff
PlanSwift takeoff software in Nigeria
HERON is 2D takeoff software for quantity surveyors working from drawings. You measure on the PDF or the CAD file, and the quantities go straight into a bill of quantities without being retyped into a spreadsheet first.
It is built by ADLM Studio in Lagos. We are registered as RC 7440343, founded in 2018, Official Technical Partner to the Nigerian Institute of Quantity Surveyors, and we have trained more than 800 AEC professionals.

Most Nigerian projects still arrive as drawings
BIM adoption is real but uneven. A firm can be modelling its own projects and still receive consultant drawings as PDFs, tender documents as scans, and revisions as a marked-up sheet. Waiting for every project to be modelled before improving the takeoff process means waiting a long time.
HERON is for that reality. It handles PDFs and CAD drawings, which is what actually lands in the inbox, and produces the same structured output the model-based tools do.
That matters because it lets a practice standardise on one measurement and pricing process regardless of what the project arrived as. Modelled jobs go through QUIV, drawing-based jobs go through HERON, and both end up in the same bill format priced by the same rate engine.
How measuring works
You work on the drawing itself. Set the scale, measure lengths, areas and counts against the sheet, and the measurements are recorded as quantities attached to bill items rather than as numbers written down somewhere separate.
Because the measurement stays attached to where it was taken, the takeoff is auditable. When a figure is queried you can see which sheet it came from and what was measured, which is the part that usually gets lost when quantities are transcribed into a spreadsheet.
Revisions are handled the same way. A superseded sheet does not silently leave old quantities in the bill.
Pricing what you measured
HERON exports to a bill of quantities, and RateGen prices it. Rates are built from first principles using material, labour and plant costs you set and can edit, with build-ups aligned to BESMM4R.
This is the difference from pricing against a fixed rate list. When cement moves, you change the material cost once and every rate that includes it recalculates, along with every bill line priced from those rates. On a market where prices move monthly, that is the difference between a bill you can defend and one you have to rebuild.
Projects sync to your ADLM account, so bills, programmes and dashboards read the same data across every machine your team signs in from.
Licensing, installation and support
HERON runs on Windows. Licensing is per user and tied to your ADLM account. After payment, sign in to the ADLM Installer Hub with the same account and the software appears ready to install. No licence keys, no waiting on an activation email.
Subscriptions are priced in naira, monthly or for a longer term at a lower monthly cost. Auto-renew is opt-in. If a subscription ends the software stops activating, but your projects, bills and exports stay in your account and on your machine, and resubscribing restores access without redoing setup.
If something goes wrong with an installation, the support page covers the fastest route, including remote sessions where someone needs to look at the machine directly. Release notes for every version are under what is new.
Common questions
What file types can HERON measure from?
PDFs and CAD drawings. That covers most of what arrives on a Nigerian project, including scanned tender documents and consultant issue sheets.
Do I need a BIM model to use it?
No. HERON exists specifically for drawing-based work. If you also have modelled projects, QUIV handles those and both feed the same rate engine and bill format.
How are rates applied to what I measure?
RateGen builds rates from material, labour and plant costs you control, aligned to BESMM4R. Change an input once and every rate and bill line using it updates.
Is it priced in naira?
Yes. Subscriptions are set and billed in naira, monthly or for a longer term at a lower monthly cost, with card payment supported directly.
