FIDIC contract management software

Run FIDIC 2017 (Red, Yellow and Silver Book) and FIDIC 1999 projects with every notice, period and certificate counted from the record, for the contractor, the Engineer and the Employer.

Every FIDIC period counted from day one

Choose the FIDIC book when you set up the project. Quanto loads its periods and time bars and counts them on the project calendar, with the Sub-Clause, who must act and by when, and what silence means.

Notice of ClaimWithin 28 days of becoming aware (20.2.1). Otherwise time-barred.
Fully detailed claimWithin 84 days (20.2.4). Otherwise the notice lapses.
Engineer's determinationWithin 42 days of the detailed claim (3.7.3). Otherwise deemed rejected.
FIDIC 1999Notice within 28 days, detailed claim within 42 days (20.1).

Where your Particular Conditions differ, change the period for that project. Count your own dates with the free time-bar calculator →

Instructions, variations and claims

  • Instructions from the Engineer or the Employer, answered by the contractor as no cost, variation or disputed.
  • Variations priced by item, submitted by the contractor, reviewed by the Engineer and approved by the Employer, every step dated and named.
  • Claims with extension of time, linked site events, photos and letters as evidence; continuing claims with interim updates.
  • Reminders two days before a deadline and when it is missed.

Payment applications and certificates

  • Progress by BOQ line for each valuation period; the payment application builds itself from it.
  • The Engineer certifies line by line, with reasons for any amount held.
  • Retention, advance recovery, materials on site and amounts held for open NCRs worked out on every certificate.
  • Printable application and certificate papers. More on payment certificates →

One record for the contractor, the Engineer and the Employer

Each party works in its own company account on the same project. Letters go out on your letterhead after a signatory signs, and arrive in the other party's inbox with read receipt, reply-by date and thread. Nothing is silently deleted: every change is logged with who and when.

Which FIDIC books are supported?
FIDIC 2017 Red, Yellow and Silver Books and the FIDIC 1999 Red Book. Other editions and bespoke contracts start from a set of values you change period by period.
Can the Engineer and the Employer use it too?
Yes. The owner, the consultant and subcontractors you invite join free, each seeing what they should.
Can I change a period for my Particular Conditions?
Yes, for each project.
Is it in Arabic?
Yes. Arabic and English on every screen, right-to-left for Arabic, on the same records.
