FIDIC 1999 Claims book

FIDIC 1999 Claims

A Guide to Claims for Extensions of Time and Additional Payment Under the Red, Yellow and Silver Books

A new book by Andy Hewitt, FICCP, FCIOB, FCICES, FQSi

Inadequately expressed claims are one of the most frequent reasons for time-consuming and costly disputes. Andy Hewitt’s latest book examines the FIDIC Red, Yellow and Silver Books. He takes a look at each clause that provides entitlement to make a claim for an extension of time and additional payment.

Andy explains in practical terms the interpretation and application of clauses. He also discusses FIDIC procedures for:

  • The giving of notices.
  • The submission of detailed particulars of the claim.
  • The Engineer’s responses and determinations.

More importantly, the book also informs the reader what FIDIC does not say. Andy addresses common problems he sees time and time again including:

  • What to include in the particulars of a claim.
  • How to demonstrate an extension of time.
  • What costs to include in a claim for additional payment.
  • How to compile a claim.
  • What ought to be in an Engineer’s response or determination.

He shares his experience and advice, and provides detailed examples, all in accordance with best professional practice.

From the foreword by Paul Gibbons, President of the Institute of Construction Claims Practitioners.

"This is a must-have book for anyone dealing with FIDIC contracts. It should be used by Employers, Contractors, Lawyers, Consultants and all those involved with effective contract administration and dispute resolution and avoidance. I highly recommend it."

About Andy Hewitt

Andy Hewitt has over 40 years’ experience in the construction industry, working in locations around the world. His earlier career included senior positions with contractors, subcontractors and consultants in project, commercial and contract management roles. During this time, he worked on many major and prestigious international projects.

For the past 15 years, Andy has specialised in contractual matters, claims and disputes on a consultancy basis and providing training and education on such matters.

FIDIC 1999 Claims may be obtained from Amazon in hard cover, paperback, and e-book formats.

A New Era For Claims Class

Back in 2009, our founder Andy Hewitt was reviewing claims on a large project for an international contractor.

As a claims specialist, the poor standard of many of the claims that passed his desk day to day horrified him. He decided that something needed to be done.  So, he wrote his first book: ‘Construction Claims & Responses: effective writing and presentation’. Following its success, Andy was often asked to present seminars on the topic.

Claims Class Was Born

Back then, there was very little available in the way of education and training on construction claims. Like Andy, most of the specialists working in the industry at the time had learnt these skills on the job.

Just under ten years ago, Andy launched Claims Class. The goal was to provide training on construction contracts and claims. He began presenting training courses in person to construction professionals all over the world. Over the years, we expanded the subjects that students could study and offered online learning.

The Next Chapter

We are excited to announce the next step in our journey. Going forward, Claims Class will become part of Hewitt Decipher Partnership.

As he moves towards retirement, Andy will be taking a step back in his current role. Instead, MD of HDP, Paul Gibbons will be picking up the reins and overseeing Claims Class. Don’t worry though, Andy will still play an active role in training and course development.

What does this mean for you?

Nothing but good news. If you’re not already familiar with HDP, take a look at their website. Over the coming months and years, we will introduce some new courses, and focus on new subjects. Teaming up with the HDP team will give us access to even more knowledge. We’ll be able to tap into the skills of the wider team who continue to work on live projects and disputes all over the world.

This expertise, gained around the world, will bolster Andy’s extensive knowledge of FIDIC and all matters relating to claims and disputes. The HDP team will position Claims Class at the forefront of contracts, claims and dispute resolution training.


Most things will remain just the same for now.

Nina will still be looking after all our clients from the point they sign up for a course, and our marketing and accounts team remain the same. However, if you are on our mailing list, you’ll see that our email addresses change to from the start of October. And if you’re not, why not sign up using the box at the bottom of this page to receive regular knowledge articles on construction contracts and claims.


FIDIC Notices

FIDIC 1999 Notices - Andy Hewitt's Latest Book

At the end of 2019 I was working with a contractor-client on several extension of time and additional cost claims. I needed to demonstrate that the contractor had complied with the contractual notice provisions in FIDIC.

This client had sent some notices. In most cases though, these didn’t comply with the contract requirements. In many cases they were completely meaningless as notices.

Need Staff Training During Lockdown? No Problem!

Whilst COVID-19 has caused immeasurable harm, it has at least taught us one good thing: people can work from home without a loss of efficiency.

But what about staff training?

Video conferencing (think Zoom, MS Teams, etc.) is being used to great effect. Remote working and meetings have saved time and cut down on travel costs. The sharing of information via webinars has also seen a huge upsurge in recent months.
