Jet grouting to start

getimage555Thousands of tonnes of concrete are being injected into the Christchurch Town Hall’s foundations as part of a multi million dollar project to strengthen the building.

This week contractors began the lengthy process of jet grouting the quakedamaged building’s foundations. They are using three grout machines that have been imported from Germany for the work, during which more than 1000 large concrete piles will be injected eight metres into the ground.

In the February 2011 earthquake the land beneath and around the Town Hall was severely damaged. Although the building itself fared relatively well, significant strengthening of its foundations is needed. Jet grouting has been identified as the most effective repair solution to address the land issues underneath the building.

‘‘Grout and water is injected into the ground at high velocity to create columns of soilcrete, which is soil cemented with grout. The columns will overlap and interlock to create an earthquake resistant underground wall of columns that will protect the building from soil movements,’’ said Project Manager Paul Youngman.

A total of 27,000 cubic metres of jet-grout concrete – which would fill 270 average family swimming pools, 37,500 bath tubs or 200 buses – will be used during the process.

A thick concrete slab will be laid over the concrete columns once the jet-grout work is complete, which will help to bring the Town Hall up to 100 per cent of New Building Standard.

Contractors have spent five months preparing the site for the jet-grouting work, which is expected to be completed in June next year. It is the first stage in the $127.5 million repair of the Town Hall.

Christchurch City Council anchor projects unit manager Liam Nolan said the restoration work would ensure the Town Hall could continue to be enjoyed by Christchurch residents for the next 50 years and beyond.

‘‘The Town Hall is one of the city’s most treasured civic and heritage buildings and this restoration work will ensure it is better and stronger than it was pre-earthquake. Starting on the Town Hall foundations marks the culmination of four years of work. This has included engineering assessments, going through a tender process and appointing a contractor to undertake the restoration work,’’ Nolan said.

‘‘By the time we’ve finished work on foundations, the ground underneath the building will be significantly stabilised, ensuring we can get on with the rest of the work needed to restore this building to a world-class facility that can be used for many years to come.’’ .

The restoration of the Town Hall, which also includes a significant upgrade and refurbishment of the facility, is due to be completed in 2018.

SCIRT, an update

getimage (7)The multi billion-dollar programme to fix Christchurch’s broken roads, bridges, footpaths and underground pipes is more than three-quarters complete.

But do not expect to see an end to the road cones and detours any time soon.

‘‘There is still a big programme to deliver even after Scirt winds up in December 2016,’’ said Christchurch City Council infrastructure rebuild general manager John Mackie.

The Stronger Christchurch Infrastructure Rebuild Team (Scirt), which is funded by the council and the Government, has completed 78 per cent of its repair and rebuild programme and should have the balance of its work wrapped up by the end of next year.

As at the end of August it had repaired or replaced 420 km of wastewater pipe, 42 km of stormwater pipe, 79 km of freshwater pipe, and more than 1 million square metres of road.

It has also fixed or replaced 84 pump stations and reservoirs, 126 bridges and culverts, and 124 retaining walls.

That work has so far cost $1.72 billion. It is forecast another $472.5 million will be spent between now and the end of the programme.

Scirt executive general manager Ian Campbell said the team was working very hard to ensure it had all the construction it was scheduled to do completed by the December 2016 deadline.

Scirt’s priority had been to fix the worst of the damage first, starting in the east, but as the programme moved towards conclusion more work would begin in the city’s west.

With most of the major repair projects either completed or under way, some lower priority jobs could be tackled.

‘‘We are now getting into more patch repairs and trenchless stuff. The work is becoming more patchy and piecemeal so what that will look like for people is they will see us moving around a bit more. The traffic management will change more often because we’ll be doing small amounts of work in more locations,’’ Campbell said.

‘‘We appreciate the support of the community . . . It has been a long slog for them putting up with the road works and we just hope we can count on their support for one more year.’’

Mackie said he was ‘‘reasonably satisfied’’ with the progress that had been made on repairing and rebuilding the city’s damaged horizontal infrastructure, but there was still a lot to do.

Not all of that work would be covered by the Scirt programme because of funding constraints.

‘‘Not everything in the city will be fixed. There will still be work to do,’’ Mackie said.

‘‘The biggest issue is funding. We could do so much more if that wasn’t a constraint, but we have to work within the means of the organisations – Crown and council.’’

Once Scirt was wound-up, responsibility for any outstanding repairs would fall to the council.

It was working on a programme to prioritise those repairs and would start with main arterial roads before turning its attention to small collector and local roads, Mackie said.

$3billion fund for Christchurch rebuild

getimage67

2008 Beijing Olympic Stadium is a Guoxin past project

Christchurch’s rebuild will get a massive capital injection thanks to a Chinese company creating a $3 billion investment fund for city projects.

Guoxin International Development Company, part of a global firm worth about $500b, said on Wednesday it was committing to raise a $3b fund for investment opportunities in the city’s post quake rebuild and regeneration.

The company was behind the main stadium for the Beijing 2008 Olympic Games and has constructed railways across China.

Local developer Fred Rahme, who is behind the Silverstream residential subdivision in Kaiapoi and Styx Mill Estate, is leading the company in Christchurch. Rahme, a Guoxin founding partner, said several Christchurch projects had already been identified, but he would not name them.

Once projects went out for tender, Guoxin would submit bids for them.

‘‘We’ve established we do have a part to play and we can really add value. Where else in the world do you have an opportunity to build a new city?’’

Because of the company’s size, it could source materials from China and across the world at a cheaper cost, which could make projects more viable, Rahme said.

Guoxin, the largest tendering and procurement company in China, has completed $750b of projects, mostly governmental and infrastructure developments, in the past 16 years.

Christchurch Mayor Lianne Dalziel signed a Letter of Cooperation and Friendship between the city council and Guoxin International on Tuesday. The letter is a non-binding agreement, and does not impose any legal or financial obligations or liabilities on the council or Guoxin.

Guoxin has also signed agreements this week with the Christchurch City Council, Canterbury Employers’ Chamber of Commerce, business advisory firm PwC, ANZ bank and law firm Cavell Leitch.

Dalziel said the move was a generous commitment from a large, reputable Chinese company.

Guoxin was confident it could win in an open tender process, she said. ‘‘I’m excited that our community will have the chance to work alongside this company as we shift our focus from recovery to regeneration.’’

Christchurch City Councillor Raf Manji said securing foreign capital had been a challenge for Christchurch.

‘‘There has been a lot of interest. We’ve had lots of visits over the previous years and we’ve not been able to execute, but we haven’t had the right platforms for investors.’’

The fund would set up a template for investment, Manji said.

‘‘The council’s role is at the political level, which is to roll out the welcome mat and say ‘Christchurch is open for business’.’’

Manji said the Guoxin deal was not exclusive. He hoped it would set the foundation for other investors.

‘‘The council is not responsible for the whole rebuild of the whole city. Our job is to make sure it can happen and we enable investors to come in and do what they need to do.’’

He named the stadium as an example of a project Guoxin might like.

‘‘It’s those type of larger scale projects that would be of interest.’’

Canterbury Employers’ Chamber of Commerce general manager Leeann Watson said Guoxin was making a significant commitment and the company’s willingness to work with Christchurch people was welcomed.

Canterbury construction $4 billion and rising

1441534746223

Metro Sports Facility

Construction spending in Christchurch has hit more than $4 billion thanks to large builds like the planned new Metro Sports Facility.

A million dollars is being spent on construction in Canterbury every two hours – and spending is still rising.

While residential building work has decreased for the first time in three years, commercial and public construction is ramping up, according to Statistics New Zealand.

More than $4.3 billion has been spent on building work in the region in the past year. The dollars going into non-residential construction have jumped 14.6  per cent in the last quarter, after increasing steadily over the past year as the rebuild ramps up.

Neil Kelly, building figures manager for Statistics New Zealand, said while many houses had already been replaced or repaired, commercial construction was still gathering speed.

“You only have to count the cranes. There’s a lot of big stuff going on and those big projects are boosting the numbers.”

Its figures translated to $83 million a week going into Canterbury’s construction industry, or nearly $12m a day.

They came from  its work in place survey, which measures the value of new residential and non-residential building, as well as alterations big enough to need consent. It does not include internal refurbishments or minor renovations, or non-building construction such as roads and other infrastructure.

Leighs Construction managing director Anthony Leighs said the commercial market was the busiest it had been in the post-quake environment.

“What we’re seeing in there’s probably the highest level of activity in the market at the moment than there’s ever been… from the total number of buildings being built across the city.”

Leighs believed the momentum would “remain very solid” for two to three more years.

The company’s “top of the pops projects” at the moment were “massive”, including the BNZ and ANZ centres, and the Burwood Hospital rebuild.

Hawkins Construction South Island regional manager Steve Taw agreed, saying the rebuild was “likely to continue at this current rate for at least another 12 months”.

He said the projects the company were working on were likely to be adding to the “ever increasing spend in the Christchurch commercial construction market”, but it was planned and not unexpected.

“It is pleasing to see confidence in our central city increasing with a number of projects in full swing.”

Ian Smith, head of project management company Building Intelligence Group in Christchurch, said while the central city skyline was full of private developers’ cranes, internal work on those buildings and the public sector spend was yet to come.

Rather than peaking , the rebuild would plateau as big projects such as they city’s new central library, Metro sports centre and convention centre got underway.

“There’s going to be quite a lot of money spent on all those buildings.”

Smith said while there were “hot spots” in construction such as the need for structural steel, the market would supply enough materials and labour in most areas.

“By and large the market has responded so far, and met demand.”

More funds for anchor project

sports-03The Government is pledging additional money to Christchurch’s metro sports facility but will not reveal how much.

Earthquake Recovery Minister Gerry Brownlee announced Tuesday Cabinet had agreed to increase Crown contribution to the major anchor project, above the $70.3 million planned in the 2013 cost sharing agreement with the Christchurch City Council.

The council committed $147m to the project.

“To ensure maintenance of a competitive tendering process, we won’t be revealing the agreed financial cap on the Crown’s commitment to delivery of the facility at this time,” Brownlee said.

While the design of the facility was still to take place, the agreed funding package meant it would include:

– An indoor aquatic hall with a 79m, 10-lane competition pool and spectator seating for 1000 people

– A 10m diving tower and warm water pool

– A learn-to-swim pool

– A leisure water area, with outdoor hot pools and two hydroslides

– Nine indoor courts for sports such as netball, basketball, futsal, floor ball, and other indoor sports, including retractable seating for 2500 spectators and function/VIP areas

– Sport New Zealand’s high performance area, which will include facilities for athletes and space for administration

– A large gym/weights facility, with up to five group fitness/multi-purpose rooms and sports health consulting rooms and facilities

– Four studio spaces for movement activity like dance

– A Sports House for administration of different sports

– A café, childcare facility and car parking for 500 vehicles (with the ability to expand in the future)

Previous plans for the facility included a 50-metre competition pool, and an complex with eight indoor courts and 2800 seats.

Sport Canterbury chief executive Julyan Falloonsaid it was great to finally have details of the project.

“We’ve been waiting for so long. It’s a great day for us,” he said.

The sports community could now plan transitional facilities and future competitions and events with more certainty.

“Now it’s about urgency to get the thing built and utilised,” Falloon said.

Netball Mainland chief executive Brigit Hearn said she was “extremely excited”.

“It’s fabulous news. It’s the end of the tunnel for us – now we can move forward and plan ahead.”

Netball Mainland had advocated for 12 courts but Hearn said getting nine courts was “certainly an improvement from where we’re at at the moment”.

The metro sport facility was initially planned to be built by early 2016 but the Government earlier this year pushed the completion date to 2020.

It is understood the business case was rejected when it finally reached the Beehive in May because costs had blown out.

Brownlee said Tuesday the intention was to open the facility to the public in 2019 and the remainder in 2020.

“As we work through the facility’s design and construction we will be looking closely at what opportunities there are to shorten those timeframes,” he said.

The Government had already purchased most of the land required to develop the facility on a central Christchurch site spanning over 70,000 square metres between Moorhouse Ave, Stewart St, St Asaph St and Antigua St.

The business case for the facility was “strong”, with more than two million visits to the facility a year expected once it opened, Brownlee said.

Christchurch Mayor Lianne Dalziel welcomed the announcement.

“The earthquakes have had a massive impact on the region’s sporting facilities and I’m confident this new centre will reignite sport and recreation participation rates, and be another good reason to live in the central city,” she said.

Concrete, concrete and more concrete!

1436745206333A construction firm has performed the largest single concrete pour of Canterbury’s rebuild to date.

Leighs Construction workers started the massive task at 1am on Saturday and worked until late afternoon, with about 1870m3 of concrete pouring into a Christchurch central city construction site’s basement.

The pour laid the foundation for the new ANZ Centre on the site of the former Triangle Centre, bordering High, Cashel and Colombo Streets.

About 370 trucks delivered the concrete.

Leighs Construction’s managing director Anthony Leighs said this was a massive milestone for the CBD rebuild as a whole.

The team craned a pump into the basement and pumped the concrete into the area from three points on High St, Cashel St and Colombo St, he said.

The next stage of the project would involve construction of the basement walls and columns, with a tower crane due on site at the end of the month.

The new four level building would include ground floor retail and hospitality areas of 1700m2 and three levels of office.

Town Hall contract signed

1436384954063The Christchurch Town Hall has been largely stripped back to its concrete frame, but the bones of the place still evoke strong memories.

Those special memories were shared yesterday as the contract was signed to restore the earthquake-damaged building over the next three years: designs sketched on a kitchen table, children graduating and people queuing to visit on opening day.

The Christchurch Town Hall will be restored and strengthened over the next three years at a cost of $127.5 million. The main auditorium has been partially stripped out in preparation for the revamp.

The contract was signed in the heritage building’s foyer with restoration and strengthening work costing $127.5 million, largely funded by $68.9 million in insurance money.

Christchurch mayor Lianne Dalziel remembered visiting the building on opening day in 1972.

“I remember thinking this [foyer space] was so big,” she said.

“The queue went for miles. We all came in and we marveled at this incredible building.

“This place has been where we come together as a city to celebrate. This adds up financially and emotionally for the benefit of the city as a whole. Roll on 2018 and the opening day.”

Original architect Sir Miles Warren remembered designing the building on his kitchen table in Church Bay over the Christmas holidays in 1965.

“That was the beginning of a wonderful building process,” he said.

“It really was the most important commission that Warren and Mahoney ever received in competition. We became a national practice rather than just Christchurch architects in the process.”

Council rebuild manager David Adamson thought of family moments.

“All my children graduated through this place,” he said.

Regional Manager Steve Taw had memories of soft rock.

“I remember the last time I came here was for a concert. It was George Thorogood and the Destroyers.”

Council chief executive Karleen Edwards said the restoration would improve the Town Hall.

“We all have memories of coming here. We all have a special memory about this place. The city has missed having the Town Hall.

“There is a real opportunity to make this place better than it was.”

The building has been largely stripped back in preparation for the restoration. Carpets have been taken up, the floor of the auditorium has been stripped out and fixtures have been removed and stored. The process has revealed the full extent of how much the floor of the main auditorium warped in the Canterbury earthquakes.

The concrete floor of the auditorium bulges like the top of a sphere. The difference in height between the centre of the bulge and the edge of the floor is about 50 centimeters. Despite this, the walls and structure of the building have remained relatively intact.

The ground beneath the Town Hall will be fixed with more than 1000 jet grout piles, creating an eight-metre deep concrete grid beneath the building. A new concrete slab for the whole Town Hall complex will be poured on top of the new piles.

The Limes Room, which has moved towards the Avon River and risen at one end, will be suspended on scaffolding while new columns are built underneath to make it level again.

Next stage for Christchurch rebuild

9bRMehChristchurch business leaders are applauding the Government’s transition proposal where the Government retains a key role in the Christchurch rebuild over the next five years.

They were concerned that the Canterbury Earthquake Recovery Authority (Cera) winding up next April year would leave a vacuum of leadership in the city and the Government’s commitment to anchor projects was flagging.

Ngai Tahu Property chief executive Tony Sewell said the proposal addressed every issue the business community had been concerned about.

He was happy with the Government’s “complete commitment” to building the Convention Centre and the Metro Sports centre. Ngai Tahu is part of a consortium chosen as the Government’s preferred partner to develop the Convention Centre.

Businesses had been concerned Government support for Christchurch was flagging “but it’s not.”

Earthquake Recovery Minister Gerry Brownlee must report back to Cabinet by the end of August on the setting up of a new urban development authority, called Regenerate Christchurch, to lead the rebuild of the central city when Cera winds up in April.

The Christchurch City Council has set up its own development authority but the Government proposes now that its development authority should “integrate” with the council’s.

The Christchurch City Council and the Government are expected to work together to set up Regenerate Christchurch and decide what its aims are, what its functions would be, what powers it had and who would pay for it.

“They have clearly set out that there is going to be a relationship between Government and council, ” Sewell said.

Asked could the council and Government work together Sewell said “it’s not a can, it’s a must”.

“The voters and the ratepayers won’t tolerate a standoff.” Sewell said.

Canterbury Employers’ Chamber of Commerce chief executive Peter Townsend said the proposal was sensible,offered a staged and predictable transition with the Government roles slowing decreasing and the council’s increasing.

It relied on collaboration between central and local government, “which I applaud” and good strong commercial governance.

He expected the Government and the council to appoint the board members of Regenerate Christchurch.

The chamber had been “pushing strongly” for a governance model over the top of the rebuild projects and that was now going to happen.

Asked if Regenerate Christchurch was just the Christchurch Central Development Unit (within Cera) with a new name, Townsend disagreed with that and said the transition proposal was a step change with new legislation, new leadership and a new collaborative relationship between the Government and council.

He expected the government and council to appoint directors to the board.of the development authority. Those people would have strong commercial experience and project management backgrounds and tracks records.

The Government’s proposal referred to some of Cera’s powers expiring or going to councils and some role for Ngai Tahu.

Kaiwhakahaere of Te Rūnanga o Ngāi Tahu, the tribal council of Ngāi Tahu,  Sir Mark Solomon said he was not aware of any detail on that.

He was on the advisory board, headed by Dame Jenny Shipley, that advised the Government. It called for a “demonstrable step-change in local leadership”.

Sir Mark said the advisory board wanted to see control start to return to the city though the Government still needed to be involved.

Hawkins Construction executive director Jim Boult said he was delighted the government confirmed its commitment to the Convention Centre and Metro Sports centre.

He would like to see timeframes on those two. The Convention Centre was “the lump in the throat” of the central city developing, he said.

No extra money for Christchurch roads

getimage (3)The city council’s hope of getting more money from the Government for fixing Christchurch’s damaged roads and underground pipes have been dealt a blow.

An independent review into the cost of fixing the city’s horizontal infrastructure – the roads, footpaths, bridges and underground pipes – has concluded the $1.8 billion committed by the Government and the $1.14b from the Christchurch City Council should be enough to do the work required to restore functionality.

The cash-strapped council hoped the review by experienced Auckland civil engineer Elena Trout would support its view that more funding was needed.

The council estimated it would cost $3.2b to restore all the infrastructure, but Trout’s report has concluded it would cost $2.9b, $348m less.

Trout said the lower cost was a result of several factors including efficiencies gained from ‘‘changed and evolved’’ design standards for wastewater, water and storm water networks, better assessment of asset damage information, rebuild efficiencies obtained by Stronger Christchurch Infrastructure Rebuild Team (Scirt) and lower than forecast inflation of construction costs.

Trout said at the time the Cost Sharing Agreement was signed only 40 per cent of the assets had been assessed.

Christchurch Mayor Lianne Dalziel would not comment on the report until she had a chance to discuss it with Earthquake Recovery Minister Gerry Brownlee. No date had been confirmed for that meeting, a council spokeswoman said.

Brownlee would also not comment until he had met with Dalziel. The pair have had the report for several weeks, but have been unable to meet because Brownlee had been in Singapore, then Iraq. He then became ill.

He was hoping to meet with Dalziel in ‘‘the next week or so’’.

The council has previously said if it was not able to find more money, streets in west Christchurch could go without repairs for decades because money to fix the roads and pipes was running out. Scirt has been working from east to west, so it was likely the bulk of the unrepaired infrastructure would be in the west of the city.

Councillor Yani Johanson said the report meant the city’s infrastructure was not going to be fixed in a timeframe or to a standard acceptable to many people.

‘‘The message from this is – the expectation that things will be put back as they were is wrong. What it shows, because of the agreements signed, people have to put up with getting less back than what they had before the earthquakes.’’

Johanson said the council must have a good look at its infrastructure strategy in the next few months to see what it could afford to do. ‘‘What it means for people is their roads are not going to be fixed as they were.’’

One of the report’s conclusions included that applying a second coat of seal, which provided a thick durable layer over the road, was not eligible for funding against the Cost Sharing Agreement.

Brownlee has previously said the horizontal infrastructure network would be at least equal to what it was before the quakes, and rejected the claim the council would to be burdened with extra costs.

‘‘It will be a long, long time before they [the council] have to start providing for maintenance on any of the work that has been done as part of the Scirt programme,’’ he said in December.

Canterbury Employers’ Chamber of Commerce chief executive Peter Townsend said the council and the Government needed to come up with an option that would serve the best interests of the city. ‘‘We don’t want to be driving around on bumpy roads for the next 20 years.’’

Anchor projects cause anxiety!

1431085048320Canterbury sports enthusiasts and businesses are “hugely disappointed” and frustrated two of Christchurch’s major anchor projects will be delayed.

The Government on Friday said completion of the metro sports facility would be delayed to early 2020 and the convention centre to late 2018.

Concern is also growing for Cathedral Square’s renovation with ASB Bank pulling out of plans for a new regional headquarters there.

Indoor sports players, swimmers and other athletes have all been waiting keenly for the metro sports facility to open but will now have to wait three more years.

The centre was initially supposed to be finished by March 2017.

Mainland Netball chief executive Bridget Hearn said the news was “hugely disappointing” for indoor sport in Canterbury.

Five years was an “incredibly long wait” and lack of indoor space in the city was problematic.

“I know we have to be patient, and we are very excited about the metro sports facility, but we have had to turn away junior teams for lack of space.”

Rugby had transitional facilities, she said, but indoor and womens sports had been left in the lurch.

Canterbury Sport chief executive Julyan Falloon said there was “real frustration” at the delay.

Aquatic and indoor sports had been “hugely compromised” since the earthquakes, he said, and organisations would find it hard to plan ahead for infrastructure across the city.

School Sport Canterbury regional sports director Bill Grogan said the delay meant students would miss out on tournament opportunities.

“Canterbury students have to keep travelling for national tournaments as we can’t host any at the moment.”

The tourism and business community was also counting on an opening date for the convention centre in late 2017.

Canterbury Employers’ Chamber of Commerce chief executive Peter Townsend said progress on the centre was “disappointingly slow” and caused uncertainty among business owners and investors.

“People need to plan ahead. We keep getting these delays and this causes uncertainty about when it will actually happen.”

Christchurch and Canterbury Convention Centre Bureau (CCCCB) manager Caroline Blanchfield said the delay was “disappointing” but she hoped the centre would be open in time for a large health conference booked in November 2018.

The Asia-Oceania Conference of Physical and Rehabilitation Medicine would bring 800 delegates and an estimated $2.1 million to the city.

She said a “back-up plan” was in place in case the centre was not finished in time.

With the convention centre delays, the halving of the size of the performing arts precinct, and no sign of an answer on the future of Christ Church Cathedral, fears were rising that Cathedral Square was becoming toxic for development.

ASB bank announced in December 2013 it would be the anchor tenant for a four-storey office block to be developed at 9 Cathedral Square, on the site of the previous ANZ building.

However, ASB spokesman Christian May said the bank broke off negotiations with Central City Estates, the family investor group that owns the site, in December 2014.

May said ASB was now talking to developers of other “high profile CBD sites” and still expected to reopen somewhere by late 2016.

Ernest Duval, of the City Owners Rebuild Entity (Core), was unsure who would be booking conventions while the square’s future remained so uncertain.

“The pressing issue is to break the impasse on the cathedral and address some of these buildings like [the half-demolished BNZ House], [and] try and move things forward, because we’re missing out on hundreds of millions of dollars worth of development,” he said.

Christchurch Central Development Unit director Baden Ewart said the Crown’s commitment to the vision of the blueprint had not changed.

Time frames had been reviewed and the public would be updated on them “as often as we can”.
