From major roading upgrades and bridge construction to water infrastructure, utilities, and local council projects, New Zealand's civil construction sector regularly faces unique challenges when it comes to working at height and accessing confined spaces.
Unlike fixed industrial facilities, civil construction sites are constantly changing. Workers often need to operate in remote locations, on uneven terrain, within excavations, around temporary structures, or inside confined spaces where traditional access and rescue systems may not be practical.
Having the right equipment and a well-planned access and rescue strategy is essential to keeping teams safe, maintaining compliance, and ensuring projects continue efficiently.
The Unique Challenges of Civil and Infrastructure Projects
Civil construction environments frequently present a combination of hazards that require specialised solutions, including:
- Working at height on bridges, retaining structures, and elevated platforms.
- Entering confined spaces such as pump stations, manholes, tanks, vaults, and utility chambers.
- Excavation and trench work requiring safe access and emergency rescue capability.
- Remote work locations where fixed anchor systems are unavailable.
- Projects that move regularly, requiring portable and adaptable safety systems.
These challenges often mean traditional fixed fall protection systems are not suitable, creating a need for lightweight, transportable, and rapidly deployable solutions.
Portable Engineered Systems for the Modern Construction Site
One of the biggest challenges facing infrastructure contractors is creating compliant anchor points in locations where no permanent structure exists.
Portable engineered height safety systems are increasingly becoming the preferred solution for these environments. Unlike traditional temporary anchors, engineered systems provide a certified overhead anchorage solution that can be rapidly deployed and relocated as project requirements change.
Whether undertaking bridge inspections, culvert maintenance, utility installation, asset maintenance, or construction activities in remote locations, portable engineered systems provide flexibility while helping maintain safe working practices.
BTS AirHook Trailer
For larger projects requiring maximum mobility, the BTS AirHook Trailer offers a highly versatile engineered anchorage solution.
Its trailer-mounted design allows the system to be transported directly to site and positioned wherever required, making it particularly valuable for:
- Roading projects
- Bridge maintenance
- Remote infrastructure works
- Asset inspections
- Temporary access requirements
- Specialised trench access and rescue
The AirHook Trailer provides a practical solution where conventional fall protection systems are unavailable or impractical.
NZ Access also holds stock of the AirHook Trailer in New Zealand, ensuring fast access to engineered height safety solutions when projects demand immediate deployment.

BTS AirHook Lite
The BTS AirHook Lite has become a popular solution for civil construction and infrastructure projects due to its compact footprint and portability.
Designed to be relocated using a forklift, the AirHook Lite can be positioned exactly where protection is required, making it ideal for projects where work areas regularly change.
Typical applications include:
- Civil construction sites
- Utility maintenance
- Water infrastructure projects
- Manufacturing facilities
- Temporary work locations
One of the key advantages of the AirHook Lite is its ability to create a compliant overhead anchor point in locations where no suitable structure exists.
Importantly, NZ Access holds AirHook Lite stock in New Zealand, helping reduce lead times and allowing projects to mobilise quickly.

Confined Space and Shoring Equipment for Civil Construction and Infrastructure Projects
Many infrastructure projects involve work inside confined spaces and trenches such as manholes, pump stations, valve chambers, tanks, wet wells, trenches and underground utility networks.
To support safe access, retrieval, and rescue operations, NZ Access offers a comprehensive range of confined space equipment suitable for a wide variety of applications.
1. Tripods
Tripods remain one of the most commonly used solutions for vertical confined space entry and rescue operations.
They provide a reliable overhead anchor point for personnel access, retrieval systems, and emergency rescue operations.
Common applications include:
- Manholes
- Pump stations
- Underground utility chambers
- Water treatment facilities
- Sewer infrastructure

2. Davits
Davit systems provide a highly versatile alternative to tripods and are particularly useful where additional reach or positioning flexibility is required.
Their modular design allows them to be configured for various access scenarios while maintaining a compact footprint on site.
Typical applications include:
- Trenching/Shoring applications
- Water infrastructure
- Utility access points
- Large tanks and vessels
- Industrial processing facilities

3. Winches
Personnel and material winches play a critical role in confined space access and rescue systems.
They allow controlled entry and retrieval of workers and can form part of an integrated emergency rescue plan when used alongside suitable anchor systems.

4. Self-Retracting Lifelines (SRLs)
SRLs provide continuous fall protection while allowing workers freedom of movement during confined space entry and work positioning activities.
Modern confined space SRLs can also provide retrieval functionality, helping streamline rescue operations should an emergency occur.

5. Confined Space Accessories
Supporting equipment such as brackets, pulleys, mounting systems, rescue devices, gas monitoring equipment, and specialised attachments help ensure confined space systems are configured correctly for the task at hand.
Selecting the right accessories can significantly improve both safety and operational efficiency on site.
Trench and Excavation Access Made Simple
Excavations and shored trenches are common across civil construction projects, particularly during utility installation, stormwater works, wastewater upgrades, and pipeline construction.
These environments require careful consideration of worker access, fall protection, and rescue planning.
The BTS PRO-6G 3-Piece Davit Trench Shoring Kit has been specifically designed to address these challenges.
This ready-to-use system mounts directly to trench shoring and provides a certified anchorage point for:
- Worker access
- Fall arrest systems
- Retrieval systems
- Emergency rescue operations
Its lightweight modular design allows for quick installation and easy relocation as work progresses along the trench line.

For contractors working on underground services and infrastructure projects, having a dedicated trench access and rescue solution can improve both safety outcomes and productivity.
Planning for Rescue from Day One
Whether working at height or entering a confined space, rescue planning should never be treated as an afterthought.
An effective rescue strategy requires consideration of:
- Access requirements
- Fall protection systems
- Retrieval methods
- Rescue equipment
- Worker competency
- Site-specific hazards
By selecting equipment designed specifically for civil construction and infrastructure environments, project teams can improve safety outcomes while reducing setup times and operational disruption.
