What commercial clients want is different from what homeowners want. Homeowners want a good wall. Main contractors and developers want a good wall that arrives when the programme says it will, with the documentation complete, and without holding up the trade behind them.
How we run commercial and civil retaining wall projects
Programme first
We price against the programme rather than in isolation, and we flag the long lead items early. Consent processing, precast manufacture and engineering sign off are the three that typically drive the critical path.
Documentation as a deliverable
PS1, consent, inspection records, compaction results, anchor test records where relevant and PS4. Supplied as a package rather than chased at the end.
Staging and access
On a live site the wall usually has to be built in sections around other trades. That gets planned rather than improvised.
Commercial retaining wall systems and when each suits
Precast panel where the run is long and the programme matters. Mass block where the wall is loaded by bulk material or may need to move. Reinforced concrete where loads are high or the wall is part of a permanent structure. Geogrid reinforced where the wall is tall and there is room behind it.
Which one suits comes out of the design, the site constraints and the programme rather than a preference.
Health, safety and neighbours on a commercial retaining job
Excavation near boundaries, existing structures and services is the highest risk part of this work. Service locating, temporary support and exclusion zones are planned rather than assumed, and on tight sites we do a pre construction condition survey of neighbouring property so there is no argument later.

Commercial Retaining Walls in Christchurch: common questions
Do you work as a subcontractor?
Yes, regularly, on both civil and building projects.
Can you work around other trades?
Yes. On live sites the wall usually gets built in sections, and that is planned rather than improvised.
What documentation do we get?
PS1, consent, inspection records, compaction and test results, and a PS4, supplied as a package.
What drives the programme?
Consent processing, precast manufacture and engineering sign off are usually the three long lead items.
Can you work as a subcontractor on a main contract?
Yes, regularly, on both civil and building projects. We price against the programme rather than in isolation and flag the long lead items early, which on retaining work are usually consent processing, precast manufacture and engineering sign off.
What documentation do we receive at handover?
PS1, the building consent, inspection records, compaction test results, anchor test records where relevant, and a PS4 on completion. Supplied as a package rather than chased afterwards, because on a commercial job the paperwork is part of the deliverable rather than an afterthought.
Do you carry out condition surveys on neighbouring property?
On tight sites, yes, before anything starts. Excavation near boundaries, existing structures and services is the highest risk part of this work, and a documented pre construction condition record removes most of the argument if a neighbour raises something later.
Recent Christchurch jobs
Boundary wall between us and the neighbour on a new build. Sorted the levels, the consent question and the fence on top in one job. Turned up when they said and left the site clean every night.
Builder here. I use them on subdivision work because the paperwork comes back complete. PS1 up front, PS4 at the end, no chasing.
Wall failed after the big rain and took part of the bank with it. Made safe within two days and rebuilt a month later with real drainage behind it.
Terraced the back lawn into two levels. Fast, tidy, fair price, and the drainage was done properly.
