Asset Inspection, Testing & Portfolio Management

Asset Inspection, Testing & Portfolio Management

Scottish Water has a large asset base used to deliver services to customers which requires suppliers to provide project specific asset inspection and testing services for both above ground and underground assets including, but not limited to asset grouping found within table 1.

Depending on the number of inspections and required timescales this may be a rolling programme to deliver a fixed number each year, or a one-off programme.

Scope

Scottish Water intend to undertake regular Inspections of our asset base in line with the SW Asset Management Strategy and as detailed within SW’s Management Approaches. The Inspections shall be used to understand the condition of our assets, which in turn will be used to better understand Service Risks to our customers and to prioritise future Investment in our assets. The Asset Inspections shall be undertaken at regular intervals and over time will be used to understand rates of deterioration and inform predictive analytical systems which will be used to inform future decisions.

The Supplier shall be required to plan, manage, undertake and report on the Asset Inspections including the confirmation of the asset condition grade, the remaining useful life of the asset along with recommendations for future work or investment on the asset. The scope of the Inspection activities is listed below and within the Inspection Guidance Documents (refer Section 8.1):

Planning and coordination of inspection

1.Source and review existing asset information to enable planning of inspections activities oIdentify / understand constraints impacting the inspection

activities (i.e. this could include but not be limited to constraints relating to isolating processes / equipment for inspection, impact on the performance of

the asset or works, access, operational support, enabling activities etc). Constraints shall be shown on the Inspections Schedule.

2.Site visit if required in order to plan the inspection activities and scope the enabling activities

3. Scheduling of inspections. The Inspections Schedule shall be updated to reflect any changes to the programme of inspections and shall be used to

coordinate the actives of the parties involved in the Inspections

4.Liaison with SW and Operational Staff to give advance notice of any inspection as well as to facilitate the inspection activities

5.Arrange and agree site access with SW Operational Staff

6.Liaison with 3rd Party’s where required to undertake the inspections (i.e. landowners, tenants, Local Authorities, SEPA etc.)

7.Secure Permissions required to undertake the Inspections. This shall include compliance with SW’s Limitation of Access, Access Transfer TOMS and

DOMS procedures which govern and control access to SW’s Assets. In addition, this shall include third party permissions (i.e. SEPA CAR Licences,

NRSWA, Planning etc.) which may be required for specific asset inspections.

8.H&S Planning including the development of a SSOW, Risk Assessment and Method Statements.

9.Where the Inspections activities are deemed to fall under the requirements of the CDM Regulations 2015 (i.e. penetrative inspections etc.) and there is

no requirement for an Enabling Contractor, the Supplier shall be appointed to the role of Principal Contractor under the CDM Regulations.

The Supplier will discharge its duties in-line with this.

1.Identify and develop scope for any enabling activities required to facilitate the site-based inspections

2.Enabling activities may be required in order to facilitate the inspection works. This could include cleaning and emptying of processes, excavations,

erection of scaffolding etc.

3.The Supplier shall develop a scope of works detailing the enabling works required to facilitate the Inspection activities.

4.For the avoidance of doubt the Supplier shall not be expected to undertake the enabling activities. The Enabling Works Scope shall be issued to the

Client who will engage a SW Framework Construction Delivery Partner to carry out the enabling activities.

5.Where enabling activities are required it is anticipated that the Enabling Contractor shall assume the role of the Principal Contractor in line with the

CDM Regulations 2015 for both the enabling and inspection activities. In such circumstances the Supplier shall be employed directly by the SW

Framework Construction Delivery Partner undertaking the enabling works.

6.Undertake site-based inspection works in line with the Inspection Guidance Documents

7.The scope of Inspection Activities shall either be the Routine Visual Inspection or the Full Detailed Inspection as defined in the call off documentation

8.Use of site-based apps for data collection where appropriate (Initially Fulcrum shall be used). As part of SW digital transformation plan the use of site-

based apps will be reviewed and updated to align with SW’s futur…
