Beach ramp, stairs may be demolished

A $250,000 plan to fix battered pieces of the St Clair sea wall ramp and stairs has been unveiled, as the Dunedin City Council confirmed concerns were raised when the beach access walkways were built.

A staff report to be considered at next week's council budget meetings said the sea wall had failed to gain a code of compliance certificate - confirming it met the requirements of the Building Act - when finished in 2004.

That was mainly due to concerns about the durability of a ramp and stairs leading from the Esplanade to the beach, highlighted in December 2004 by the first of a series of failures caused by severe weather, the report by council community and recreation services manager Mick Reece said.

Since then, the ramp and stairs had together been damaged a further five times, most recently when heavy seas and pounding waves last September forced the ramp's closure, after concrete was cracked, exposing steel reinforcing rods.

Mr Reece's report said the performance of the sea wall itself remained satisfactory, but the ramp and stairs needed to be repaired before the structure met building consent requirements.

The structure was designed by council consultant Duffill Watts and King, but the company had since merged with Coomes Consulting in Australia to become CPG, which had not accepted liability for the failings.

Mr Reece said, given the passage of time and other factors, it appeared the chances of a successful outcome from any legal action were "uncertain at best".

And, with any action likely to cost between $60,000 and $150,000, he recommended staff continued to investigate a negotiated settlement instead.

Council staff had met CPG representatives, and were seeking "assistance" in further design work to repair the structure, he said.

The report presented four options for repairing the structure, ranging from redesigning features in their existing locations, to removing those most exposed to the elements, at a cost that could range from $250,000 to $700,000.

Mr Reece recommended the $250,000 option which would mean the ramp and three of four flights of stairs were removed from the most exposed area, between Beach St and Forbury Rd.

One flight of stairs would remain opposite Beach St, in the exposed area, to provide beach access for surfers, as would stairs at the Forbury Rd end of the Esplanade.

The council already had $120,000 available for the work in its 2012-13 pre-draft budget, but that was $130,000 short.

The report would be considered by councillors as part of next week's pre-draft annual plan and long-term plan meetings, before public consultation.

Seawall background

It`s fairly obvious, looking at the seawall and the various failures along the way that the Council simply got what they paid for. There is an engineering truism - quick, cheap or correct: pick any two...

Without engaging in idle speculation (as I actually possess some knowledge of the events surrounding the design and construction of the seawall), the blame being heaped on the engineers / contractor in this instance is a little unfair.

As is typical for these types of project, initial designs were presented to Council for the construction of the ramps, which were considerably more expensive that that which was finally built, involving substantially more concrete, reinforcing and site works. Likewise, the detailing for handrails originally specified different (read correct grade stainless) hardware.  These designs were rejected on cost grounds, and the designers were instructed to provide a lower cost option.

The outcome of this decision is clear for all to see.

Beach access

Not so.

The steps that frequently were damaged and some removed were of similar design the ones we have at present. The parallel steps at both ends of the beach successfully withstood the ravages of time.

Beach access

Mikenette seems to see the old sea wall through rose-tinted glasses. Apart from it being in imminent danger of collapse, the old access stairs failed on a regular basis and were continually removed. If you look at any old photos of the wall, you can see where they used to be - before being removed.

Beach access

I articulated it at the time and nothing has changed. The access stairs and ramp were of flawed design. I cannot believe an engineer could have got it so wrong. Their design simply failed to acknowledge the natural forces frequently at work on that part of the coast and failed to acknowledge what worked best on the old sea wall. Namely parallel steps down to the beach.

Those parallel steps need to be rebuilt into the wall to provide an effective long term solution. No brainer! 

A compulsion to spend

These sea-wall options are crazy! To even suggest spending another $250,000 on a project that failed to meet contractual obligations denotes a lack of effective DCC management capability for the role. Additionally, to state that," $120,000 is available for this work" shows an expectation by DCC that the project was doomed to failure and "funds" must be budgeted for "repairs" from the outset. And to also have a hand out for an additional $130,000  once again reveals the DCC staff attitude that they only have to ask and it will be given.

Repair work is the responsibility of Duffill, Watts and King - end of story, and if they have been able to sell their business while abdicating incomplete contract responsibility, this also shows lack of effective contract governance by the DCC. Come on Councillors - SAY NO!

 

Staff changes

Fire those responsible and replace them with a couple of 5-year-olds, who would stand a better chance of seeing through the flaws in the original plan.

A chartered engineer cannot sidestep liability for work that has been signed off.
