How to bill by quantity takeoff and progress protocols

A bill of quantities with contract prices on schedule items, site measurements, progress from quantities, lump-sum stages and a period progress protocol for invoicing.

Who it's for: project managers and site managers who bill the investor by quantities of work completed.

What you'll do: enter the bill of quantities on schedule items, record measurements from site and issue a progress protocol for a period, the basis for an interim invoice.

Before you start

  • Quantity takeoff and progress protocols are on the Pro plan.
  • The bill of quantities is the amount of work planned before starting, usually from the cost estimate. A measurement is the quantity actually done and measured on site.
  • The bill of quantities is the price for the investor, not the cost plan. You keep the cost plan separately. See How to control a construction budget.

Steps

1. Enter the bill of quantities

  1. In the schedule, open a task and go to the Bill of quantities section.
  2. Enter the quantity, unit and Contract unit price from the contract with the investor. You can also enter the item's value, and the unit price is calculated for you.
  3. When the task has a cost plan, click set price with markup… to set the price as the planned cost plus a markup.
  4. You can import the bill of quantities from an XLSX file together with the schedule, e.g. a cost estimate exported to Excel. See How to build a construction schedule.

Mark a lump-sum stage as Settled as a whole (stage price) and enter the stage price. The tasks under it have no prices.

2. Record measurements

  1. In the task's Measured quantities section, click Add measurement.
  2. Enter the quantity done, the measurement date and a note, e.g. “measured with the surveyor”. Click Save measurement.
  3. The item shows how much is done, how much is left and when it was last measured.

An item with a bill of quantities has no manually entered percentage. Its progress comes from the measurements.

3. Issue a progress protocol

  1. Go to Protocols and click New protocol.
  2. Enter the start and end of the period. The items are calculated from the measurements recorded in that period: before, in the period, cumulative, remaining and value for the period.
  3. After adding measurements, click Recalculate.
  4. Click Issue. The investor or the project manager signs the protocol separately with Sign.
  5. Download the protocol as a PDF.

What happens next

  • A signature in the app is an approval with name, role and time. It isn't a handwritten or qualified signature. Sign the paper copy on a printout of the PDF.
  • A correction after issuing is a New version. The previous one stays, since it may already have reached the investor.
  • You compare the value from measurements with the item's costs, so you see the profit on each piece of work.

Troubleshooting

  • The item's progress is 0%. The item has a bill of quantities but no measurements yet. Enter the first measurement.
  • The protocol has no items. No measurements were recorded in the chosen period.
  • I can't save a measurement without signal. Measurements and protocols need an internet connection.
