Orange Zone, Oxford Terrace & 4 Red Zone, CBD Bridges

Wed 08.02.12. Pre 2010-2011 quakes, Jake rented a house on Oxford Tce beside Avon River, in the Avon Loop. Since the quakes began on 04.09.10, Oxford Tce between Barbadoes St & Fitzgerald Ave was serial quake damaged, by 10 000 quakes, big & small, with houses shaken to bits or tilted in liquefaction mud. Avon River bank slumped with 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 took its time getting Tonkin & Taylor geotech reports, which placed inhabitants & property owners under huge stress, as they couldn't get on with their lives, while officials hemmed & hawed about quake trashed 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 & going downriver to the end of Oxford Tce by Fitzgerald Ave Bridge.

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

I parked near the Council Central Library, Peterborough St. Post 22.02.11 quake, Gloucester St Central Library was abandoned in the red zone CBD. Every time I drove along Peterborough St towards Avon River it looked more derelict, with overgrown properties & business & home demolition sites. Some businesses struggled on, some houses were inhabited.

Some Peterbrough St properties, where I'd snapped quake pics months ago, were empty & desolate. Besides weedy sites, someone had sprinkled flower seeds to brighten up demolition sites: poppies & daisies...

Near PGC bldg, demolition site, where 18 people died when the bldg collapsed in the 22.02.11 quake, Manchester St Bridge, 1 span, between Cambridge Tce & Oxford Tce looked OK. Pavement buckling between abutment & span, Cambridge Tce side.

The bridge was still a NZDF checkpoint into the CBD red zone, soldiers checking vehicle entry by cordon fences. Citizens were still banned from the CBD a year post Feb 22 quake, demolitions ongoing, but no rebuild, yet.

17 months post 04.09.10 quake & 1 year post 22.02.11 quake, "rebuild" was a joke, as insurance pay outs were delayed & insurers upped premiums, complaining about "risk." Canterbury citizens were experiencing Disaster Capitalism by insurers, CERA, EQC, Fletchers, landlords & contractors.

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

Madras St Bridge, angled bridge on a river bend, 1 span each angle arm, by Oxford Tce Baptist Church & The Poplars apartments demolition sites. The N-S bridge span was horizontally rotated clockwise with concrete corners sticking out, or crunched into abutments. I saw that horizontal rotation of concrete spans on several bridges. There was spalling by concrete bridge abutments, concrete footpaths & steps by the 9/11 Firefighters Reserve.

Two Madras St Bridge concrete abutments had moved / sunk about a foot on Avon River bank, Kilmore St side. I used my size 6 jandal (11 inches / 27 cm long) often to measure depth / width of quake cracks.

By The Bricks, Barbadoes St Bridge, 1 span: Concrete spalling by bridge abutments. The span had horizontally rotated anti-clockwise, the opposite way 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.

Barbadoes Cemetery stone wall, which collapsed on Cambridge Tce in the Feb 22 quake, was unfixed, just a mud bank. Months ago, post Feb 22 quake, when I'd passed that way during wet weather, noxious fluids oozed from the cemetery with liquefaction mud, across the road into Avon River.

One concrete abutment of Barbadoes St Bridge was cracked & leaned about 4 inches away from the bridge span. On the other side of the bridge on Avon River bank, a concrete drain manhole slumped towards the river.

Oxford Tce by fence cordoned, Holiday Inn was a mess, worse than what I'd seen post Feb 22 quake, when workmen did patch repairs to the road. Some Oxford Tce houses were still inhabited in the orange zone, but most were red stickered or abandoned, between house or flat demolition sites. By Bangor St junction, a brick electricity substation leaned towards Avon River.

Holiday Inn was demolished in July 2015.

Why CERA took so long to decide on orange zoned, Oxford Tce land, only CERA could explain. Any passerby could see that Oxford Tce was finished & only idiots would want to redevelop quake-trashed, riverside land again. Unproven "land remediation" was engineer-speak for taxpayer funding for decades to come.

Engineers would use taxpayers' money to make underground explosions & check soil results. Their reasons being they were checking "liquefaction" effects, so they could improve concrete foundations in post quake bldgs. It was risible that CERA minister Brownlee & State Housing minister Smith extolled such codswallop! All they had to do was walk any Christchurch river bank to see liquefaction trashing of concrete foundations & concrete curbs.

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

So the 1 m 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 liquefaction mud 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.

Meanwhile some Oxford Tce 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 & construction clamour for months, must've gone bonkers, with frustration & anger at Council's & CERA's bureaucratic inertia.

By Jake's old rental house, a hand written sign on a power pole read:

      S
      L
      O
     W
PLEASE

The hand made, speed limit sign cajoled passing cars, not CERA's inertia.

Deep & wide slumping cracks, I'd seen months ago, were still beside the road on Avon River bank. Little had been done by Council road workers to fill them in. The house which Jake had rented pre quakes was quake cracked & boarded. Liquefaction silt mounds I'd seen on pavements months ago were still there. Oxford Tce was dusty & bumpy with gravel repairs. So much for Council's City Care.

Across Avon River, Fitzgerald Ave N bound lane, which had collapsed riverside in the Feb 22 quake was being rebuilt - months of construction work, with a large, concrete retaining wall riverside & traffic congestion on the other side of the road.

2011: When I'd driven Luke to tech in the mornings, we'd watched Fitzgerald Ave rebuild progress, as a pile driver drove concrete columns deep into river mud. Fitzgerald Ave rebuild was nearing completion after a year of traffic congestion. The other side of the road then needed rebuilding. Pity the stalwarts existing nearby.

Oxford Tce within Avon Loop was eventually red zoned by CERA. All the red zone houses were demolished by CERA.

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

Due to quake destruction & road rebuild, at Fitzgerald Ave /Avonside Dr / Kilmore St crossing, a mass of white & red plastic barriers channelled traffic along one side of Fitzgerald Ave Bridge to one side of Fitzgerald Ave going to Bealey Ave. That traffic congestion went on for a year post 22.02.11 quake.

Council still had a big job to repair those Avon River bridges. And there were many more quake- broken, Avon River bridges. Council roads & bridge repairs would be incorporated into SCIRT, which would take years to repair Christchurch roads & bridges properly. If ever?

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

"There's no incentive for bringing buildings up to earthquake standards & that affects all our cities not just Christchurch." Greedy prat. Tell that to the families of the 185 quake dead Townshend!

If the Property Council disliked citizens' & Council's Green City ideas, then they could take their money elsewhere. Others with integrity could take their place.

Wed 08.02.12: 9.08 pm, mag 4.2 quake, 9 km depth, 10 km SE of Lyttelton.
11.06 pm, mag 4.3 quake, 9 km depth, 10 km E of Lyttelton.

Thurs 09.02.12. 0.51 am, mag 4.2 quake, 9 km depth, 10 km E of Lyttelton. (Geonet)

Felt them all.

As so many old & new bldgs failed in Christchurch during the 22.02.11 quake, designers, architects, engineers & builders had nothing to be proud of. Canterbury was a known liquefaction region, long before the 2010-2011 quakes. As bldgs had to be repeatedly checked straight after quakes & long after quakes, nothing good could be said about engineer checks before & after quakes.

Due to being suckled on Accident Compensation Corporation pay outs, Kiwis had a "no blame," no lawsuit mentality, when blame & vengeance was needed. "Blame Mother Nature, don't blame people," cried stupid people. Result of that self deception was that quake victims who'd lost loved ones & suffered injuries were expected to be "resilient" & saintly & act with forgiving restraint.

I was sceptical of the official "checking" line regarding red, green & yellow stickering of bldgs, straight after the 04.09.10 quake. 17 months down the line, my scepticism was repeatedly confirmed by disparate checking & repeated evidence of shoddy bldg inspections & bldg owners' tardiness regarding inspections, revealed at the Royal Commission of Inquiry. Engineers just stuck to the latest revised bldg code, concocted blindly whenever they felt like it.

Like so many things post quakes, even the death toll was recently revised from 182 to 185. Three more people had died from long term quake injuries.

A year post 22.02.11 quake, orange zoners & white zoners still waited for geotech engineers, Tonkin & Taylor to investigate their land properly. To the delight of Disaster Capitalism, insurers who delayed payments, awaiting Tonkin & Taylor's land zoning.

Anyone driving around Christchurch could see the ruined, rotting state of bldgs awaiting tardy zoning: ruined bldgs, masonry lying where it fell months ago, tarps blown off bldgs, weedy lots, liquefaction mud still on properties. A disgusting mess, all held up by CERA & Tonkin & Taylor geotech engineers.
