EGB123 PUPs
| Question | Answer |
|---|---|
| Many PUP systems are installed... | over time |
| Civil engineers all have a duty of care: | - Not to harm PUP itself - Not to allow PUP to pose Health, Safety, and Environmental hazards |
| We need to know where PUP systems are presently located so that we: | - can plan and design in a way that does not adversely impact them -can plan and design in a way that accommodates any necessary systems change/s - don’t damage them during construction |
| We need to know where PUP systems are presently located so that we can also... | coordinate with PUP systems’ owners where changes may be necessary |
| PUP Systems in the urban context are systems of infrastructure assets that: | - convey something (eg water reticulation) and/or - change state of something (eg voltage transformer) - For community benefit |
| In an urban context, most often, PUP systems need to be located in or near public spaces for... | ease of access for maintenance, operations etc To avoid interference with private land uses |
| Conveyance PUP Systems in the urban context are located, where possible, within a strip of public land such as a: | - casement (road land) OR - easement (special purpose land) |
| In the urban context, the benefits of locating Conveyance PUP Systems within public land are that it... | makes access easier longitudinal configuration often suits conveyance |
| In the urban context, technical aspects sometimes requires Conveyance PUP Systems to be installed through private land allotments, for example.... | stormwater, sewer due to alignment requirements for hydraulics (fluid flow) |
| In the urban context, Change of State PUP Systems may be located within: | - road casement or an easement - public land (eg park) - private land allotments |
| In the urban context, Change of State PUP Systems sometimes may nee dot be installed within... | a structure/building |
| PUP Systems with Individual Property Connections | Electricity connections |
| Not every property has connection to every... | PUP system, eg - Town gas - Hybrid fibre coaxial (HFC) broadband |
| Examples of PUP Systems and large land uses include hospitals and shopping centres, which may have: | significant numbers of on-site PUP systems and associated on-site management systems |
| Who owns PUP Systems Located within an Urban Context? | Government agencies Statutory authorities and government owned corporations (GOCs) Private agencies |
| Government agencies eg | Local government (City Council) - stormwater State government eg Transport and Main Roads - some road PUP |
| Statutory authorities and government owned corporations (GOCs) eg | Urban Utilities - sewer, water reticulation Energex - electricity reticulation |
| Private agencies eg | Total Peripherals Group (TPG) -optic fibre Transurban - PUP for their toll-roads |

| How do we know where the PUP systems are? The key "on-plan" sources | Brisbane City Council's City Plan Mapping Brisbane City Council's eBIMAP2 Dial Before You Dig (DBYD) |
| Brisbane City Council's City Plan Mapping: | - shows certain BCC PUP systems -gives approximate locations |
| Brisbane City Council's eBIMAP2: | - shows stormwater, water reticulation, sewerage systems - gives approximate locations |
| Dial Before You Dig (DBYD): | - a referral service for locating underground utilities anywhere in Australia - plans provide information about presence only - plans do not necessarily pinpoint exact locations |
| Multitude of PUP systems exist | also multitude of plans detailing their type and location |
| Rarely do plans "line up" or even relate to one-another | eg telecoms PUP plans from one business may not acknowledge another's' telecoms |
| Some plans can be very rough | eg may not be keyed to the Cadastral (property boundary) plan |
| Some content is rastered (pixelated) rather than vectored | Reduces clarity |
| Personnel access pits and covers provide evidence of... | underground PUP system alignments |
| At-grade and overhead PUP systems can... | be surveyed |
| Ground truthing is... | vital |
| Underground PUP systems always require... | special care |
| Some ways of locating underground PUP systems: | - Ground Penetrating Radar creates a visual image of subsurface - non-invasive but requires expertise |
| Some ways of locating underground PUP systems: | - pipeline video inspection can be carried out using eg tractor camera - non-invasive but requires expertise |
| Some ways of locating underground PUP systems | - vacuum excavation (invasive) uses pressurised water to turn material into slurry - loosened soil is the vacuumed for disposal/reinstatement - reduces risks of: - damage to infrastructure - injury to workers |
| We cannot rely solely on all the different ways of locating underground PUP systems, and therefore... | every time we proceed to excavate, every care must be taken through appropriate practices |
| Regarding the practical issues around PUP systems location, for most civil engineering planning, design, construction and management: | - non only do we need to determine where each PUP system is positioned - we need to determine relationships and physical proxmities between them This is largely an exploratory process |
| When undertaking exploratory process, we need to: | - inform PUP systems' owners - have Workplace Health and Safety protocals in place - have Risk Management Planning in place - appreciate the costs involved |
| Some larger activities may also require: | - public (community) engagement - Traffic Management Plan - Environmental Management Plan |
