Procurement Management

A proper Procurement Strategy is essential to ensure risk is apportioned to meet the planned objectives of the contracting parties. Harris Consulting International’s experience and expertise in this area adds value and benefit to our clients – typically in the following areas:

  • Ascertaining commercial viability of projects
  • Determining responsibilities of contracting parties
  • Selection of appropriate procurement strategy; drafting / amendment of contract terms and conditions to reflect risk strategy
  • Appointment of the professional team and the construction team
  • Tendering procedures
  • Project management and cost control procedures
  • Identification of conditions and grounds for potential contractual claims
  • Identifying and appraising areas of potential risk and liability, which if neglected may result in loss of commercial viability
  • Implementing strategies to safeguard clients’ contractual and commercial interests

We fully support the principles of ‘partnering’ and ‘strategic alliancing’ espoused by Sir Michael Latham in his report on the construction industry, ‘Constructing the Team’ (1994) and by Sir John Egan in his report, ‘Rethinking Construction’ (1998).

It is our opinion, however, that ‘partnering’ and ‘alliancing’ do not eradicate the requirement to ensure that the parties’ obligations and the scope of services/supply are fully and properly defined. This brings certainty to the parties’ contracting arrangements and reduces the potential for disputes.

Pre and Post Contract Commercial Management

Harris Consulting International’s pre and post-contract commercial management service provides clients with the assurance that their commercial interests will be protected through the employment of dedicated and highly skilled surveyors and engineers.

Commercial awareness and the correct administration of construction contracts during the site phase are vital to project success and financial viability. This applies equally (if not more so) to the contract formation process.

Proper recording of the contract formation process and meticulous care in the production and checking of the contract documents for signature are essential.

As part of Harris Consulting International’s commercial management service,  personnel can be provided to carry out a specific short term task or a more long term commercial role.

Whether working on a short or long term commission, our quantity surveying service includes inter alia:

  • Contract formation and contract document production
  • Establishing, implementing and maintaining appropriate records to ensure commercial interests are safeguarded
  • Processing payment applications
  • Valuation of variations / Assessments and quotations for compensation events
  • Financial auditing and reporting
  • Identification of and compliance with contract notice provisions
  • Preparation of claims for loss and expense and/or damages
  • Preparation, negotiation and agreement of final accounts

Contract Audit and Best Practice Procedures

Harris Consulting International is regularly appointed to carry out contract audits on final accounts, contract administration and procedures and/or discrete areas of a particular contract.

The audit role typically involves verifying whether the contract and/or final account process has been operated and completed in accordance with the Contract. However, project sometimes benefit from audits being carried out before and/or during the works to give effect to changes to ensure delivery of projects / services in accordance with the parties’ contractual obligations.

Our staff is highly skilled in undertaking commercial and/or contract audits on current projects or at final account stage. Our ability to interpret contractual obligations, identify the scope of works and assimilate where the risk lies, leads to cost certainty and confidence for our clients in their budget and contract management.

Forensic Analysis for Assessment of Delay/Extension of Time and Quantum

Changes to the circumstances envisaged by and dealt with in a contract almost inevitably lead to changed costs for one or other of the parties.

The fundamental basis for the identification and evaluation of any change(s) to the envisaged circumstances is an accurate analysis/description of the nature of the change – and this must be supported by as much corroborating evidence as is reasonably possible if the party seeking cost redress (or the party seeking to avoid claimed redress) is to be successful.

The collection, interpretation and representation of this evidence in a manner which would be acceptable to a court of law (i.e. in a forensic manner) requires considerable skill and experience if a party is to put its case in the best possible way to the other side.

The interpretation and analysis of the evidence must be carried out in a way which reveals the true causes of the changes to the party’s operations and the inescapable effects which those changes had upon the costs incurred by the party.

In order to establish the true position – which will allow its client to make fully informed decisions – Harris Consulting International specialises in carrying out:

  • the detailed forensic identification and description of change
  • the meticulous collection and presentation of evidence, and
  • the proper interpretation and analysis of such evidence.

Whilst these principles and procedures are equally applicable (and sometimes required) with respect to variations ordered by the Employer (which are usually within the contemplation of the contract), it is more often the case that they are required when the changed circumstances are not so readily apparent, or there are a large number of changes affecting the contract works at the same time.

In such cases lengthy delays and/or considerable additional cost are the likely consequence(s), and the parties are likely to hold differing views on the extent to which liquidated damages are applicable.

In respect of any such changes, Harris Consulting International specialises in:

  • determining the true quantum (i.e. in assessing the justifiable compensation due) under the contract, and
  • determining the correct period by which the contract should be extended (i.e. determining the correct EOT or ‘extension of time’) for the purposes of the application of liquidated damages.

Dispute Resolution

UK Construction Adjudication

Harris Consulting International’s extensive experience of adjudication includes not only acting on behalf of referring and responding parties, but also acting as the adjudicator; Michael Harris (RICS) is a registered adjudicator.

Sometimes disputes are unavoidable but using authoritative and proven analytical skills, we detail clients’ cases in a manner that expedites outcomes that help safeguard our clients’ financial and contractual interests.

Harris Consulting International, under the auspices of Michael Harris have taken part in over 400 adjudications either representing parties or as appointed Adjudicator’s.  In addition, Harris Consulting International employs self-motivated individuals who have undertaken specialist professional training in the area of adjudication.

Adjudication as a means of resolving disputes quickly, and in most cases, finally, is the most frequently used dispute resolution process in construction. However, in the last decade, adjudication has advanced from a rudimentary dispute resolution process to a more complex one since its statutory inclusion in most construction contracts from 1998 under the ‘Housing Grants, Construction and Regeneration Act 1996 (Part II: Construction Contracts; “Construction Act”), incorporating proposed changes in the Local Democracy, Economic Development and Construction Bill (Part 8), as amended (2009).

Adjudication provides plenty of pitfalls for the unwary and those who fail to keep abreast of such developments. Staying at the leading edge of adjudication involves regular appraisal of changes in the law and continued professional development in what is a very specialist and rapidly evolving field.

However we do believe that adjudication is no exception to the general rule that, whether claiming or defending, there is no substitute for knowing and understanding the case and presenting it in clear and precise terms whether to a contracting party or to the tribunal.

Harris Consulting International strives at all times to achieve this objective and has experienced a level of success matched only by the best practitioners operating in this specialist field.
