Review Construction Strategy including sequencing and critical path.

Undertake actions from Procurement Strategy or administration of Building Contract as required.

6 CONSTRUCTION 6 Construction 

STAGE J - K Stage J-K  Mobilisation , Construction to Practical Completion 

Offsite manufacturing and onsite construction in accordance with the Construction Programme

Regular review of progress against programme and any Quality Objectives including site inspections.

Administration of Building Contract.

Resolution of Design Queries from site as

they arise

Implementation of Soft Landing Strategy including agreement of information required for commissioning, training, handover, asset management, future monitoring and maintenance and ongoing compilation of "as- constructed" information.

7 USE AND AFTERCARE 7 Use and aftercare 

STAGE L Stage L  Post Practical Completion 

Implementation of Soft Landings Strategy including Post Occupancy Evaluation.

Conclude administration of Building Contract

Review of Project Performance in use and analysis of Project Information for use on future projects.

Updating of Project Information, as required, in response to Asset Management and Facilities Management feedback and modifications.

PROCUREMENT Procurement

The stage 1, 2, 3 and 4 outputs may be used for tendering and contract purposes depending on the Procurement Strategy as influenced by the clients Risk Profile, time, cost and quality aspirations and how Early Contractor Involvement and Specialist Subcontractor input is to be undertaken.

PROGRAMME Programme 

Stage 4, 5 and 6 activities may occur concurrently depending on the Procurement Strategy. Work may also be undertaken in packages to facilitate its development by Specialist Subcontractors. Early package procurement may also occur during stage 3 depending on the procurement route. The Project Programme should set out the times scales for these overlapping design and, where appropriate, construction stages.

PLANNING Planning 

Planning Applications typically be made using the stage 3 (Developed Design) output, however, certain clients may wish this task to be undertaken earlier. The project or practice specificPlanofWorkidentifieswhenthePlanningApplicationistobemade. Certain aspects of the Technical Design may also be required as part of the application or in respond to planning conditions.
