Beschreibung

Disruption of a construction project is of key concern to the contractor as any delay to the project will involve the contractor in financial loss, unless those losses can be recovered from the employer. It is, however, acknowledged that disruption claims in construction are difficult to prove, usually the result of poor or inaccurate project records, but the cost of lost productivity or reduced efficiency to the contractor under these circumstances is very real. Practical Guide to Disruption and Productivity Loss on Construction & Engineering Projects is clearly written to explain the key causes of disruption and productivity loss. Disruption claims rest on proof of causation, so it discusses the project records that are necessary to demonstrate the causes of disruption, lost productivity and reduced efficiency in detail. Quantification of a disruption claim in terms of delay to activities and the associated costs are also fully discussed. With many worked examples throughout the text, this will be an essential book for anyone either preparing or assessing a disruption and loss of productivity claims, including architects, contract administrators, project managers and quantity surveyors as well as contractors, contracts consultants and construction lawyers.

Preface

I have been involved in the construction industry in the UK and overseas for over 50 years, both at project level in planning and project positions and in head-office organisations in managerial roles. During this time, and in particular during the last 20 years which I have spent primarily in time-related disputes and claims, I have become increasingly aware of the lack of a comprehensive, easy to understand, practical and ‘down to earth’ reference book for those involved in the preparation and assessment of disruption and loss of productivity claims.

The views expressed by me in this book represent many years’ experience of looking at projects that have gone wrong and resulted in a dispute(s) between the parties. In practice, many projects are completed without major claims, and where these do occur they are settled promptly and professionally without escalating into a formal dispute. Unfortunately, a claim that evolves into a formal dispute often stretches the resources of the parties and their consultants and can add financial pressure in resolving the dispute.

Many construction firms, large and small alike, lack staff with the skills required to produce well-presented disrupted and loss of productivity claims. Similarly, the receiving party, architect, engineer or employer, often does not have the in-house skills to review such submissions and claims thoroughly, and delays making a proper decision or resorts to external consultants for assistance.

Chapter 1Introduction

1.1 Introduction

This book is a practical text that seeks to demystify the measurement of site labour/resource productivity.

In line with the Society of Construction Law Delay and Disruption Protocol launched in October 2002, this book also puts forward a rational and sufficiently accurate method of quantifying the effects of disruption in terms of both cost and time.

Disruption claims impact on the whole of the construction industry, so this book is written for all those members of the construction industry who are involved in submitting, evaluating, awarding, managing and resolving disruption claims.

It is my view that the methods used to quantify disruption must be readily usable by site management. Agreement at this level is the target of the solutions proposed, as it is hoped that this prevents the claim escalating to the formal dispute resolution procedures. It has been my experience that resolving claims for delay and disruption at site level reduces the souring of site relationships and prevents loss of senior management/head office time, which in turn prevents the cost of formal dispute resolution (adjudication, arbitration and litigation).
