Cost calculator

What does the evidence cost your team?

Set the hours your counsel, solicitors, experts and project team spend on the evidence in a construction dispute: discussing it, finding earlier replies, reading it, meeting about it and bundling it. The calculator prices that time and shows how much of it a shared, searchable record of the evidence and its discussion might free.

Every rate and reduction is labelled with its basis, so you can see which parts of the result rest on published research and which are assumptions you can change. Nothing you enter leaves your browser.

  • Published an official, surveyed or court figure, or one derived from published data
  • Company or vendor reported by a company, or by a study a vendor commissioned
  • VeriCase assumption an estimate by VeriCase that you can change
  • Your figure a figure you have entered

Your matter

Start from the closest kind of matter, then adjust anything. A starting point sets the team, their hours and the meetings; it leaves your rates and reductions as they are.

Kind of matter

Large adjudication: a team of fourteen, with VeriCase’s estimates of their hours and meetings. Change any figure to match your matter.

1

Multiplies one matter. Use 3 or 4 for serial adjudications on one project. No credit is taken for reusing discussion between matters.

30% of email time

VeriCase assumption The time spent finding the earlier reply, drawing or attachment before answering. The nearest benchmark is 5.5 hours a week spent looking for project data (PlanGrid with FMI, 2018).

Guideline rates are the HMCTS solicitors’ guideline hourly rates in effect from 01 January 2026, which the courts use as a starting point for the summary assessment of costs. Rates charged in practice may be higher: choose your own rates to enter them in the team table.

Hours freed are not always hours billed less. Studies commissioned by software vendors count only part of the time saved as value: Forrester counted 25% in a 2019 study for Microsoft and 80% in a 2024 study for Thomson Reuters. Tick to value only the share you choose; the hours freed are unaffected.

Meetings

Set each kind of meeting and who attends. By default every meeting stays as it is: no independent study measures how much meeting time a written record of the discussion replaces. Choose a reduction only where a written thread could do the meeting’s work.

Conferences with counsel

Counted only when the central case includes assumptions: untick “Central case: published research only” under Reductions to choose one.

Who attends: Conferences with counsel

9 attendees, 108 person-hours, £32,004 on one matter.

Usually kept: advice and strategy need the meeting. The TCC Guide asks parties to consider in every case whether attendance by their most senior advocates is reasonably required at a case management conference (paragraph 5.8.1); the same discipline applies here.

Experts’ and technical meetings

Counted only when the central case includes assumptions: untick “Central case: published research only” under Reductions to choose one.

Who attends: Experts’ and technical meetings

9 attendees, 108 person-hours, £24,710 on one matter.

Experts’ discussions still need a meeting. The exchanges about documents around them are the part a shared thread might take over.

Progress calls

Counted only when the central case includes assumptions: untick “Central case: published research only” under Reductions to choose one.

Who attends: Progress calls

6 attendees, 72 person-hours, £17,454 on one matter.

Updates on progress are the meetings most readily shortened, or replaced by a written thread.

Reductions

The share of each activity’s time that a shared record might free, in per cent. The central case gives the figure that might be freed; the low and high cases set the range in the results. A central figure you change is marked as yours.

Leaves out of the central case the reductions that no study measures (reading and bundling) and the company and vendor figures for meetings. Untick it to include them.

How the figures work

  1. The cost of the time is hours multiplied by each person’s rate. Finding earlier replies is a share of each person’s time on email. Meeting time is the number of meetings, multiplied by their length and by each attendee on the team.
  2. Time freed is each activity’s hours multiplied by its reduction. Its value is that time multiplied by the rate, scaled by the share you choose to value if you tick that option.
  3. More than one matter multiplies one matter by the number of matters. No credit is taken for reusing discussion across matters.
  4. The default team, hours and meeting pattern describe a large construction adjudication and are VeriCase estimates.
  5. Leading counsel’s £600 an hour is an assumption: published judgments record counsel’s brief fees rather than hourly rates. Junior counsel’s £150 is the Attorney General’s London A Panel rate, a discounted public-sector rate; rates charged to private clients are typically higher, so enter your own if you know them.
  6. In statutory adjudication each party usually bears its own costs, so the cost of this time is not usually recoverable from the other party. The result is an estimate of time and its cost, not a measured saving.

Notes and sources

  1. Discussing and finding earlier replies: McKinsey Global Institute, The social economy: Unlocking value and productivity through social technologies, July 2012 (Exhibit 20), estimated that social technologies could free 25% to 30% of the time that interaction workers (high-skill knowledge workers) spend reading and answering email, and 30% to 35% of the time they spend searching for and gathering information. The central case uses the lower figures; the low cases (15% and 20%) are VeriCase discounts. These are modelled estimates for knowledge workers generally, drawn from data of 2009, not measured results in construction or law, and they predate VeriCase.
  2. Meetings: no independent study measures how much meeting time a shared record of the discussion removes, so the central case counts none. The optional figures are a 14% fall in the average time each person spent in meetings at Shopify in the first five months of 2023, compared with the same months of 2022, which followed a policy of cancelling recurring meetings rather than a software tool (its chief financial officer, interviewed in Fortune, 14 July 2023); and an 18.9% average fall in the number of meetings in a study commissioned by Microsoft (Forrester Consulting, The Total Economic Impact of Microsoft Teams, April 2019).
  3. Reading and bundling: VeriCase assumptions (5% and 10% in the central case when assumptions are included); no study measures them. For context, the review of documents typically accounted for about 73% of the cost of producing electronic disclosure in 57 productions studied by the RAND Institute for Civil Justice (Where the Money Goes, 2012); and in White Winston Select Asset Funds LLC v Mahon [2019] EWHC 1381 (Ch), some 200 to 250 of the more than 8,000 pages in the chronological files were referred to at trial (paragraph 43).
  4. Value placed on time freed: studies of workplace software commonly count only part of the time saved as value. Forrester’s study of Thomson Reuters legal research tools for an in-house legal department (November 2024) counted 80%; its study of Microsoft Teams (April 2019) counted 25%. Both were commissioned by the vendor.
  5. Solicitors’ rates: HMCTS solicitors’ guideline hourly rates in effect from 01 January 2026, by band and grade (A partner, B senior associate, C associate, D trainee or paralegal). The courts use guideline rates as a starting point for the summary assessment of costs; actual charges may be higher. The option of rates claimed in a Technology and Construction Court case uses the hourly rates claimed by the claimant’s solicitors in Lime Technology Ltd v Liverpool City Council [2025] EWHC 2037 (TCC), a procurement claim (partner £1,345.50, senior associate £895.50, associate £463.50), which the judge described as “at the upper range of any possible range” (paragraph 14); no paralegal rate was recorded, so the London 1 Grade D rate is used.
  6. Counsel: there is no official guideline hourly rate for barristers. Junior counsel’s £150 is the Attorney General’s London A Panel rate for government civil work from 01 April 2025, a discounted public-sector rate. £175 and £350 are the lowest and highest of the minimum hourly rates, before value added tax, that Crown Office Chambers publishes for public access work in cases valued under £100,000, depending on the barrister’s seniority (checked 06 October 2026). King’s Counsel at £600 is a VeriCase assumption, with £1,000 as an upper sensitivity; £270 is the Attorney General’s rate from 01 April 2025 for a King’s Counsel of ten years or more whose current rate is £200 to £269, a public-sector floor. Published judgments generally record counsel’s brief fees rather than hourly rates.
  7. Experts: £253.73 is the average hourly rate for report writing reported by expert witnesses working in the civil courts, across all disciplines, in the Bond Solon Expert Witness Survey 2025 (published 07 November 2025; 525 respondents). No current survey reports rates by discipline; replace it with the rates your experts quote.
  8. Client team: the commercial manager’s £47.50 is an estimate of the internal cost to the contractor, derived from a gross salary of £57,000 with employer National Insurance, the statutory minimum employer pension contribution and a 25% overhead, over 1,740 working hours a year. The project manager’s £45 and the director’s £85 are VeriCase assumptions.
  9. Benchmarks for the checks: PlanGrid with FMI, Construction Disconnected, 2018 (599 construction industry leaders; 5.5 hours a week looking for project data and information); McKinsey Global Institute, July 2012 (28% of the working week on email); Rogelberg with Otter.ai, The Cost of Unnecessary Meeting Attendance, 2022 (632 employees; 18 hours a week in meetings); Hon Shu Pang v Justin Zinda [2024] EWHC 176 (KB), paragraphs 17 and 21; Nazzini and Godhe, King’s College London with the Adjudication Society, Construction Adjudication in the United Kingdom, November 2024. Each benchmark covers more than work on the evidence, so the estimates should sit below it.
  10. Starting points: team sizes, minutes, hours and meeting patterns are VeriCase estimates based on practitioner experience, chosen as lower bounds. The same times for each person are used in every starting point of a calculator, so a larger matter costs more only because it has more items, discussions, bundles, meetings or people.
  11. Recovery of costs: in statutory adjudication each party usually bears its own legal and expert costs. In litigation and arbitration some costs may be recoverable from, or payable to, the other party.
  12. The figures show professional time and its cost at the rates shown, and the time that might be freed in each case. They are illustrations: VeriCase has not measured the time it saves, and whether time freed becomes a saving depends on how the time is billed and used.
