At D2 Rail, we provide efficient construction planning ensuring early, continuous and consistent integration of construction knowledge into the conceptual planning, design, construction, and operations of a project. Our high calibre team has a proven track record in the rail industry gained from large, complex, multidisciplinary programmes of work and always develop effective design/construction solutions through coordinated assessment and robust challenge.

Construction Assessments/Option Development

Early integration and communication of a project construction strategy is vital to achieve a design and construction programme that is relatively stable and ultimately cost effective.

D2 Rail has significant construction experience in multidisciplinary rail systems projects. We use this knowledge and experience to produce construction strategies and option selection constructability reports, enabling option evaluation and selection. Following option selection we provide construction and staging support to the design process to maintain understanding of the overall strategy(s) and continuously refine constructability statements and supporting documentation.

Blockade/Possession Programmes

Clear integration of discipline scope, interfaces and logistics is essential to successfully deliver complex possession and blockade works.

D2 Rail has significant experience in creating, developing, and managing multidisciplinary schedules. Our team of multidisciplinary experts can help to define scope, influence methodology and develop an optimum multidisciplinary delivery strategy with agreed interfaces. Our team has successfully developed and managed blockade schedules on a number of highly complex blockades resulting in successful work delivery.

Box Plans/Access Strategies

Early identification of the Project’s staging and possession access strategy is essential; this requirement has a significant bearing on the likely success of a project.

If disruptive possession access is known early, the access can be agreed with stakeholders in time to provide maximum discount, reducing project cost and improving certainty of delivery.

Early understanding and communication of the construction strategy is essential to influencing design requirements and subsequent design programmes.

Early communication can lead to prevention of late design changes, additional design work, change to construction sequences, which also provides a level of certainty and stability.

D2 Rail has significant experience and success in developing multidisciplinary construction and staging strategies. Our team has successfully developed and managed access strategies on a number of major projects and programmes of work resulting in possession access cost savings and successful work delivery.

4D Planning

4D Planning software provides a dynamic planning tool that can really help open up communication to create detailed programmes.

Our expert 4D capabilities have been used to develop 4D visualisations for complex blockade schedules, which has proven to be extremely valuable in communicating highly complex programmes across organisations, both internally and externally. Internally, the 4D visualisation is widely used by the project teams to help with integration, remove clashes and optimise logistics between the disciplines. The output is used in white board briefings and in presentations to peer review panels. Externally, the 4D animations have been successfully used in stakeholder engagement.

D2 Rail has identified that when planning and visualisation capabilities work in harmony, the result is a unique product that provides clear understanding of programmes for all.
