Engineering and development constraints
Constraints
Construction staging due to
heavy traffic within the city
centre
Existing lane widths in the
city centre, which in some
instances are below the
required design standard
Existing pedestrian
footpath widths in the city
centre, which in some
instances are below the
design standard
High density of utilities and
services underneath the
road and footpath
Concept design provisions
Including constructability requirements in preparing and
finalising the concept design
Reviewing comments and incorporating changes into the
proposal detailed design.
Where possible, complying with lane width requirements
as described above in Table 3-8
Identifying substandard lane widths and considering them
as part of the required Road Safety Audit to allow high-risk
areas to be addressed during the proposal’s detailed
design.
Setting the objective of not further reducing any existing
substandard footway widths under the proposal.
Considering the design and location of any existing
utilities and avoiding impacting these services where
possible
Relocating any impacted utilities in consultation with the
service providers
Allowance for light rail, new
bus and cycleway
infrastructure
Ongoing road maintenance
projects and other works
taking place within the city
centre
Substandard filter lanes
and turning lanes
A number of existing
mature and significant
trees within the road
margins
Including utility and service provisions in the proposal’s
detailed design.
Provisioning the Access Strategy projects in the
development of the concept design to remove conflicts
Including the existing Access Strategy project concept and
detailed designs in our planning and design.
Coordinating the proposal’s design with the other Access
Strategy projects where there is a requirement to work
along the same streets and across conflicting
intersections. Allowing for managing these conflicts in the
proposal’s concept and detailed designs and setting out a
risk register to manage identified issues.
Providing a design that complies with the design
standards where feasible
Identifying substandard filter lanes and turning lanes and
considering them as part of the required Road Safety
Audit to allow high-risk areas to be addressed during the
proposal’s detailed design.
Keeping the loss of trees to the absolute minimum
Identifying the location of significant tress and avoiding
any impact on them
Implementing tree management protocol when
undertaking the works to ensure no notable canopy and
root structure damage (as discussed in section 6.6.4)
