Forensic analysis and reporting (cost & time)

Aspects of project management that are primarily focused on understanding the causes of project issues and problems and/or developing and assessing the implication of issues or problems.

Developing an 'expert' report typically used either to defend, or prosecute, a claim requires a very disciplined approach: It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts (Sir Arthur Conan Doyle). A good 'expert report' is based on researched and validated data, with the determined facts (supported by the data) clearly separated from expert opinion derived from the facts. After many years of practice, we are getting quite good at this.

Assessing Delay & Disruption

Delay claims, linked to disruption and acceleration cost claims are common in the construction and engineering industries and are becoming more common in other projects. A key area of each claim, present in most contractual disputes, involves assertions of delay with associated disruption and/or acceleration costs. This type of claim usually appears after normal contract processes are being severely tested and the contractor has engaged experts to assist its cause. This section is designed to help both industry decision makers, and  ADR and legal professionals, understand the options available to disputants in assessing ‘delay’ to help them quickly cut through the fog of expertise present in many major disputes to achieve a speedy determination.

PP: Assessing Delay and Disruption - Tribunals Beware. Delay claims, linked to disruption and acceleration cost claims are common. This paper:
- Describes the origins, strengths and weaknesses of ‘Critical Path’ scheduling.
- Outlines the current ‘state of play’ with regards to the practice of scheduling.
- Describes the primary approaches to delay analysis, their strengths and weaknesses, including:
    - As-Built v As-Planned
    - Impacted As-Planned
    - Collapsed As-Built
    - Window Analysis and its variant, Time Impact Analysis.
- Describes the type of record needed to support the delay analysis.
It concludes by suggesting some questions a tribunal (or manager) may choose to direct to various scheduling experts appearing before them to ascertain the robustness of the evidence being presented to help turn the mass of data typically accumulated in a ‘claim’ into information. The complexities around concurrent and parallel delays are discussed .

PP: Delay, Disruption and Acceleration Costs. Unfortunately, most prolongation or disruption claims seem to result in excessively large cost claims that damage any possibility of negotiating a reasonable settlement. This paper examines the theoretical underpinnings of ‘delay and disruption’ costs to suggest a realistic basis for their calculation. It is designed to help non-experts see through the ‘smoke and mirrors’ of schedule claims to understand what’s likely to be real, what’s feasible and what’s hyperbole.

Blg: Dealing with client delay. Preventing or minimizing client induced delay is a common issue. Whilst this type of delay can never be completely eliminated, they can be reduced by applying this pragmatic six stage approach.

Concurrent and Parallel Delays

Concurrent and parallel delays occur when two separate causes of delay affect the same project during the same, or overlapping, periods of time. In this situation determining the cause of the delay and consequently which party is responsible for the consequences of the delay can be very complex.

Concurrent Delay"Time is money" is an often heard statement that drives and motivates every player engaged in the project management industry. Ironically it is also the dual elements of time and money that cause some of the most time and money consuming disputes, particularly in the construction and engineering industries. One of the most troubled and complicated area is that relating to the concept of concurrent delay, which is a strongly contested topic. Both parties to a construction contract regularly use concurrent delay as an excuse to avoid responsibility for extension of time claims and the assessment of liquidated damages.

To date there has been no uniform application of legal principles to the concept of concurrent delay. This is largely due to the fact that the answer to the concurrent delay dilemma is complicated because it is requires consideration of the interaction of many different factors. The aim of this section is twofold. The first is to identify the variety of principles or methodologies that may be followed in resolving parallel delays disputes. The second is to outline the various practical aspects relating to dealing with concurrent delays disputes, by examining methods of assessing concurrent delays, categories of information that must be sourced in resolving parallel delays disputes and practical contractual management techniques in securing relevant and contemporaneous information to deal with the consequences of parallel delays within a construction contract.

PP: Concurrent Delays in Contracts. The concept of concurrent delay is a strongly contested topic in the building and construction industry. The aim of this paper by Jim Doyle is twofold. The first is to identify the variety of principles or methodologies that may be followed in resolving parallel delays disputes. The second is to outline the various practical aspects relating to dealing with concurrent delays disputes (see the original paper).

Claims & Expert Witness

Mosaic provides expert assistance in the preparation and defense of claims.

Defective Work Claims

A defective work claims is the most common claim made by building owners against their building or construction contractor. The cost and consequences associated with resolving a defective work claim can be minimized if the contract is prepared for each individual project setting out effective and feasible methods of risk allocation together with clear obligations in relation to standards, quality and the reliance placed on the contractor's skill and expertise.

Preventing disputes is better than resolving disputes. The introduction of Adjudication in the UK and Australia has pressurized project administration, causing a radical re-think of many traditional project management and contract management processes. The Acts apply to every business involved in Building and Construction including contractors, subcontractors, clients, suppliers and professional firms. Construction industry professionals need to address and manage the impact of the Acts on projects in which they are involved. For examples, see the Casewatch series on Adjudication.
