A discussion group on the delivery of capital WASH projects in humanitarian and development contexts. Project delivery components have been developed over many years to assist with the delivery of engineering infrastructure and services. These are wide-ranging; contracts, specifications, standards, codes of practice, management systems and quality assurance and programmes are among the most widely used methods but many others exist. The majority of these components were developed for use in commercial projects of the industrialised countries in the global North. This group provides a forum in which the requirements for project delivery components are developed and refined so they are appropriate for resource-scarce or precarious environments.

Contract is a legally binding agreement between two or more parties who agree to buy or sell goods and services from one another. There are many different types of contracts. The three most common contract types include: Fixed-Price contracts, Cost-plus contracts, Time and Materials contracts.
They maybe combine different types of contracts to create one that hits all the high notes of their business exchange. Some business exchanges include a range of products and services, such as labor and equipment.
The contract defines how the work will be managed and what the responsibilities of each party to the contract are. Whereas the specifications define the works themselves and what exactly is to be undertaken. So the contract sets out "who" is responsible for the various aspects of work and how their management is administered, whereas the specification details exactly "what" is to be built and the required level of quality.
