Year 2 CERA. Orange Zone, Oxford Terrace. 4 Red Zone, CBD Bridges.

Orange zone, 4 CBD bridges, red zone focus. Wed 08.02.12. Pre 2010-2011 quakes, Jake had rented a house on Oxford Tce beside Avon River, in the Avon Loop. Since quakes began, 04.09.10, Darfield Quake, Oxford Tce between Barbadoes St & Fitzgerald Ave was damaged, by 10 000 quakes, houses shaken to bits or tilted in quakemire. Avon River bank slumped, deep cracks riverside, caused by lateral spreading.

Like other CERA designated orange zones, that section of Oxford Tce was limbo-land: "Further assessment required," while CERA got Tonkin & Taylor geotech reports, placing inhabitants & property owners under stress, as they couldn't live properly while officials dithered about quaked land.

Land zoning done by CERA had anomalies, so citizens asked for reviews of their land zoning from green zone to red zone, or vice versa. Others wanted CERA to stop dithering & make quicker land decisions about orange & white zones.

I wanted to see 4 CBD bridges, former red zone, starting at Manchester St Bridge & trekking downriver to the end of Oxford Tce by Fitzgerald Ave Bridge.

Over 17 quake months, so far, Christchurch roads had degenerated, some patch repairs done by Council. Most bridges had survived quakes, traffic flowing, but concrete bridge abutments at either end of bridges were battered, cracked, spalled, part separated from bridge spans, due to shaking & riverbank slumping. Some metal handrails for pedestrians on bridge sides were broken or skewed. Never mind riverbank slumping below bridge abutments & riverbed slumping below concrete piers. Would rebars in bridge concrete stretch like elastic, snap, or bend?

Parked near Council Central Library, Peterborough St. Post 22.02.11 Killer Quake, Gloucester St Central Library was abandoned in the red zone CBD. Whenever I drove Peterborough St towards Avon River it looked more derelict: ghosts, overgrown gardens, demolition sites. Some businesses struggled on, some houses inhabited.

Peterborough St: Some properties where I'd snapped months before were empty. Besides weedy sites, someone had sprinkled flower seeds to brighten up demolition sites: poppies, daisies...

Manchester St Bridge: Near PGC demolition site, where 18 people died when the multi-storey collapsed in the 22.02.11 Killer Quake. Manchester St Bridge, concrete, 1 span, between Cambridge Tce & Oxford Tce looked OK. Pavement buckling between abutment & span, Cambridge Tce side.

EXTREME DANGER KEEP OUT. The bridge was still a NZDF checkpoint into CBD red zone, soldiers checking vehicle entry by a steel mesh fence cordon. Citizens, still banned from CBD a year post Feb 22 Killer Quake, demolitions ongoing, no rebuild, yet.

17 months post 04.09.10 Darfield Quake & 1 year post 22.02.11 Killer Quake, "rebuild" was a joke, as insurance payouts were delayed & insurers upped premiums, complaining about "risk." Cantabrians were experiencing Disaster Capitalism by insurers, CERA, EQC, Fletcher, landlords, contractors.

Wikipedia referred to Naomi Klein's The Shock Doctrine, whereby Klein espoused Disaster Capitalism: Some developed countries' politicians "exploited crises to push through controversial exploitative policies while citizens are too emotionally & physically distracted by disasters to mount effective resistance." NZ National govt's / CERA's red zoning of trashed areas was Disaster Capitalism: citizens losing their land rights, cheapskate offers from insurers & Crown, NZ National govt land-grabbing the lot.

NZ National govt did not protect residential red zoners from slow insurers. Residential red zoning by NZ National govt benefitted insurers, not insured, red zone home owners. Red zoning enabled insurers to pay less to red zone home owners, for a like-for-like rebuild of their damaged homes. Never mind 2007 RV. According to protest leader Rev Coleman, red zoners would have to go to the High Court to get fair payout from insurers. But citizens were pushing back by protests in parks & streets. I would attend several protests in 2012 for my blog pics.

Barbadoes St Bridge, by The Bricks: Concrete, 1 span. Concrete spalling at bridge abutments. Span, horizontally rotated anti-clockwise, opp rotation to Madras St Bridge. Some Christchurch footbridges would be demolished, like Medway St Footbridge (stored at Ferrymead). It would be years before road bridges were fixed properly by SCIRT.

Barbadoes St Cemetery stone wall, which collapsed on Cambridge Tce in the Feb 22 Killer Quake: unfixed, just a mud bank. Months before, post Feb 22 Killer Quake, when I'd trekked past during wet weather, noxious fluids oozed from the cemetery in quakemire, across the sunken road into Avon River.

Oxford Tce: Steel mesh fence cordoned, Holiday Inn ghost a mess, worse than what I'd seen post Feb 22 Killer Quake, when workmen did patch repairs to the road. Some Oxford Tce houses, still inhabited in the orange zone, most were red stickered, or abandoned, between house or flat demolition sites. Ghost houses. Off Oxford Tce, Bangor St pump house, old brick bldg, leaned towards Avon River. In Avon Loop, Bangor St pump house would be the only bldg surviving quakes & CERA's residential red zoning.

Holiday Inn would be demolished, July 2015.

Why CERA took so long deciding on orange zoned, Oxford Tce land, only CERA could explain. Anyone could see Oxford Tce was finished. Only idiots would want to redevelop that trashed, riverside land again.

Swampland rebuild: "Land remediation" was engineer-speak for funding for decades to come. Engineers would use taxpayers' money to make underground explosions, then check soil results. Reasoning: they were checking "liquefaction" effects, so they could improve concrete foundations in post quake bldgs. CERA minister Brownlee & State Housing minister Smith extolled such nonsense! Anyone walking any Christchurch river bank could see liquefaction trashing of concrete foundations, concrete curbs, concrete drains...

In 1987-88 when I'd worked for DeBeers Koffiefontein mine in SA, I experienced earthquakes caused by underground mine explosions. The effects were different from Christchurch quakes. Mining explosion waves were higher frequency than quake waves. During one mine quake, I stood near our lemon tree, the tree quivered, leaves rustling in sync with high frequency waves. I'd never seen trees quiver like that in Christchurch quakes. Seismic waves in Christchurch caused trees to move up & down while a wave passed. I experienced that once while holding onto our nectarine tree when a quake wave passed.

So the 1m thick concrete slabs which engineers evolved for liquefaction prone land, post quakes, wouldn't stop a house on its thick slab floating up & down in a big quake. The thickened concrete slab would hopefully just stop quakemire penetrating the house floor. I doubted the thickened, concrete slab foundation would stop liquefaction flooding, as garden soil level would be level with the foundation slab top & ground settlement would cause flooding during liquefaction. The only real test for a house on a thicker, concrete slab foundation would be another big quake, not underground explosions.

Oxford Tce: Meanwhile, some ghost houses were red stickered, uninhabitable by Council, others were green stickered, inhabitable. Anyone living in Third World, Oxford Tce, imbibing silt dust & hearing the Fitzgerald Ave pile-driver & road rebuild clamour for months, must've gone bonkers at Council's & CERA's bureaucratic inertia.

Deep, wide slumping cracks, I'd seen months before, were still beside the road on Avon River bank. Little was done by Council road workers to infill. The house which Jake rented pre-quakes was cracked, boarded. Quakemire mounds I'd seen on pavements months before were still there. Oxford Tce: dusty, bumpy, gravel repaired. Council's City Care?

Across Avon River, Fitzgerald Ave N bound lane, which collapsed riverside in the Feb 22 Killer Quake was being rebuilt, months of construction work: large, concrete retaining wall riverside, traffic congestion, other side of the road. Drove that congested road daily, taking Luke to Sullivan Ave tech lectures.


08.02.12. House demolition site & quake damaged house, orange zone, Oxford Tce, 1 year post 22.02.11 quake







2011: When I'd driven Luke to tech in the mornings, we'd watched Fitzgerald Ave rebuild progress: pile-driver drove concrete columns into river mud. Fitzgerald Ave N bound rebuild neared completion after a year of traffic congestion. Other side of the road would then be rebuilt. Pity stalwarts existing nearby.

Rebuilt N bound lane was poor engineering: quakes rose Avon River bed, the new N bound lane was built too low by that Avon River bend. In future whenever Avon River flooded, rebuilt N bound lane would flood too!

Oxford Tce within Avon Loop would eventually be red zoned by CERA. All red zone houses would be demolished by CERA, incl Jake's old rental.

Fitzgerald Ave / Avonside Dr / Kilmore St intersection: Congested traffic, channeled by orange / white, plastic bollards, from Bealey Ave to one side of Fitzgerald Ave, due to rebuild of collapsed N bound Fitzgerald Ave & Fitzgerald Ave Bridge repair. Traffic congestion continued for a year post 22.02.11 Killer Quake.

Fitzgerald Ave Bridge: Concrete, 2 spans, anti-clockwise rotated. Only half used & traffic congested, due to nearby road rebuild. Construction crew & equipment occupied other half of the bridge. Bridge abutments, spalled in places, patched cracks across the road before the bridge. Kilmore St side, concrete abutment, cracked, tagged. Post quake tagging became a big problem in Christchurch. All those newly bared walls to spray-paint.

Council still had a big job to repair those 4 Avon River bridges. There were many more broken Avon River bridges for Council to repair. Council roads & bridge repairs would be incorporated into SCIRT, which would take years to repair Christchurch roads & bridges properly.

08.02.11. The Press quoted Property Council's, Connal Townshend, complaining about Council's rebuild plan:

"There's no incentive for bringing buildings up to earthquake standards & that affects all our cities not just Christchurch."

Tell that to the families of the 185 quake dead Townshend!

*Trekked Peterborough St, Manchester St, Madras St, Barbadoes St, Oxford Tce, Fitzgerald Ave. 133 snaps.

Wed 08.02.12: 9.08pm, M4.2 quake, 9km depth, 10km SE of Lyttelton.
11.06pm, M4.3 quake, 9km depth, 10km E of Lyttelton.

Thurs 09.02.12. 0.51am, M4.2 quake, 9km depth, 10km E of Lyttelton. (GeoNet)

Felt them all.

As so many old & new bldgs failed in Christchurch during the 22.02.11 Killer Quake, designers, architects, engineers, builders had nothing to be proud of. Poor bldg checks by engineers pertained. Canterbury was a known liquefaction region, long before 2010-2011 quakes.

Suckled on Accident Compensation Corporation payouts, Kiwis had a "no blame, no lawsuit" mentality. "Mother Nature's to blame," cried deluded people.

I was sceptical of official "checking" regarding red, green, yellow stickering of bldgs, post 04.09.10 Darfield Quake. 17 months later, stickers showed disparate checking & shoddy bldg inspections. Bldg owners' tardiness regarding inspections was shown at the Royal Commission of Inquiry. Engineers just stuck to the latest revised bldg code. Even if a bldg was built to code, there was no guarantee the building would not collapse in a quake!

Death toll was recently revised from 182 to 185. Three more people died from long term quake injuries.

A year post 22.02.11 Killer Quake, orange zoners & white zoners still waited for geotech engineers, Tonkin & Taylor to check their land properly. Disaster Capitalism insurers just delayed payments, awaiting Tonkin & Taylor's land zoning.

Anyone driving around Christchurch could see ghosts awaiting slow zoning: ruined bldgs, masonry lying where it fell, tarps blown off, weedy lots, grey quakemire still on properties. A mess, compounded by by slow CERA & slow Tonkin & Taylor geotech engineers.
