SEGURIDAD, CONDICIONES GENERALES

C.1 Background

Examples are included here for common contractual scenarios related to the management of assets. These have been shown in two distinct groups (C.1 buildings and C.2 infrastructure) in order to reflect the practices in the two asset areas.

The purpose of these scenarios is to explain where the organization (to which this PAS is directed) could be in the supply chain.

Each of the contractual scenarios described should be arranged so as to make the provision of PIMs/AIMs possible throughout the life of the asset, passing from one organization to the next in order to provide and maintain a full asset information data set.

C.2 Contractual scenarios related to

management of buildings

C.2.1 General

There are a variety of contractual arrangements between parties involved in asset delivery projects, and some of these are described in this clause. These arrangements will ultimately determine the way the operations teams are appointed/engaged.

Contractual arrangements need to be carefully

considered for each of these scenarios, and care should be taken to ensure duplication of responsibility is avoided whilst making sure that all relevant issues and duties are covered. These scenarios illustrate how responsibility for different parts of the asset information management system may change under different contractual conditions.

For each of these scenarios there is an equivalent situation where the asset is already owned, and the project is to redevelop it.

C.2.2 Develop, own, operate scenario

The first scenario described is where an owner will retain control of an asset once it has been constructed.

The owner engages a supply chain to deliver an asset

The owner then engages an operator supply chain to manage the asset once it has been completed and successfully handed over. The operator supply chain is engaged via a contract with the employer.

C.2.3 Develop, own, let scenario

In the second scenario, here the owner will let out the asset to a tenant once it has been completed, becoming a landlord.

As in the first scenario the owner has engaged the supply chain to provide the asset. Once the asset has been handed over, the employer lets the asset to tenants. This arrangement results in the possibility of split responsibilities for the operation of the asset, the landlord will retain responsibility for the operation and maintenance of the common areas whereas the various tenants will be responsible for their own particular areas. In this case there may be a number of contracts for maintenance or operation awarded on the same asset.

C.2.4 Develop, own, sell scenario

In this case the developer sells off the asset to an owner or landlord after completion.

The owner may choose to use the asset himself, or may choose to let it to tenants. This may also result in split responsibilities for the operation and maintenance of the asset, with the landlord and tenants each making arrangements with operator supply chains.

C.3 Contractual scenarios related to

management of infrastructure

C.3.1 Background

As with the contractual scenarios described in C.1, there are a range of scenarios which relate to the management of infrastructure. Also as described in C.1, these arrangements will determine the way the operations teams are appointed/engaged.

C.3.2 Own, change, own scenario

This is where an asset owner identifies the need for works to be carried out to an existing asset.

28

An example may be where the owner of an existing asset – in this case a bridge – identifies that the deck needs to be replaced. The owner arranges for a

contracted party to replace the deck part of the bridge system, and the bridge is then handed back to the operational part of the organization on completion.

C.3.3 Develop, transfer, own scenario

In this case a developer builds an asset in support of a wider project, transfers the operation of the asset to a third party which takes on ownership of the asset.

The example used here is where a construction

company builds a sewerage network to support a new housing development. On completion the network is transferred to the local water supply authority which takes on the ownership and its operational responsibilities.

It is also common practice for the ownership of roads within housing estates to be transferred from the developer to the local authority on completion, with the local authority taking on the maintenance obligations.

C.3.4 Own, enhance, own scenario

Here an asset owner wants to enhance an existing asset which it will retain ownership of.

In this example, the owner of an existing motorway needs to increase the capacity and opts to widen it. The owner contracts an external organization to carry out the widening works and then takes back the motorway on completion.

C.3.5 Own, transfer, operate/maintain, transfer, own (DBFO) scenario

This deals with a situation whereby an asset is transferred to an operator for a set period and then handed back to the owner at the end.

An example may be where an existing road network is transferred to a maintainer under a franchise agreement. The maintainer will be responsible for bringing the network up to a good standard, carry out ongoing maintenance for the period of the franchise, and then ownership of the network will revert to the original owner at the end of the franchise period. This scenario is also called DBFO (design, build,
