Effective Contract-Type Selection in the Dredging Industry

CEDA is pleased to announce the release of a new CEDA guidance paper by its Working Group on Effective Contract-Type Selection (WGECS), initiated by the CEDA Dredging Management Commission (DMC).

Button-Download your copy // download-button.png (5 K)This new guidance paper along with the Checklist for Successful Management released by CEDA in 2017 (available to CEDA members free of charge), aims to assist parties to works contract in identifying and understanding the various risks, considerations and constraints that exist in the industry, with the goal of increasing the effectiveness of contract and project management.

From generic procurement process to objective scoring methodology

The paper has three component parts, each can also be read on its own:

  1. The first part is a generic procurement process flowchart that visualises the procurement process as a whole. Five stages are described and explained that set out the main considerations to be taken into account by those procuring works, resulting in the selection of the contract type;
  2. The second part is a table that sets out six key aspects of procurement route/contract selection and details numerous sub-aspects that can be taken into account by users in assessing their optimum procurement strategy. The strength of this table is that it is established by a DMC-recognised group of specialists operating at both sides of dredging and offshore industry — both owners and contractors.
  3. The third part combines the output of the first two parts, resulting in an objective scoring methodology that allows users to compare their specific project with various standardised contract types.

Visualisations of Owner’s Uncertainty (higher value indicates increased uncertainty). The farther away from the centre of the chart, the higher the uncertainty/variability of the key aspect for the user.

This comprehensive paper provides an accessible guide to the general procurement path, and includes the overall process, important points of consideration, and guidance on various factors influenced by certain standard contract types.

It also provides an in-depth analytical method for objectively measuring a user’s specific project, and related requirements and constraints, and for comparison against standardised contract types. This allows a user to apply a more scientific, auditable, and demonstrable basis for the ultimate contract selection, and it compares with the more generic and basic methods of selection.

A product experts with specialist industry knowledge

This guidance paper has been produced by a group of international experts with an unrivalled wealth of specialist industry knowledge and experience within dredging projects. Their broadly diverse backgrounds and range of expertise, as well as CEDA’s quality control, are the guarantee for a comprehensive, high-quality and objective treatment of the subject.

Paper launched at CEDA Dredging Days 2019

The paper was presented by WG Chair, Charles Wilsoncroft, HKA, UK, at CEDA Dredging Days 2019 (7-8 November 2019, Rotterdam, the Netherlands). The presentation can be downloaded below.
