Company Director, Raewyn Sharp

Company Director, Raewyn SharpFor most of the time, the operators at Sharp Concrete Cutters and Drillers work with a degree of autonomy.  That being said Company Director, Raewyn Sharp is no stranger to a construction site.  In fact, she can often be found on site ensuring high-quality workmanship, as well as offering concrete cutting and drilling services to our cities project and site managers.

Raewyn Sharp has spent most of her working life on construction sites, for various companies, projects, and locations across New Zealand.

The Girl in the Steel-Cap Boots

Originally published in Business North.

A career spanning 30 years of wearing steel cap boots has taken Raewyn Sharp of” Sharp Concrete Cutters & Drillers Ltd” all over New Zealand. From the “think big” construction projects of Muldoon days such as the Motonui Gas-to Gasoline plant in Taranaki and Marsden Point Oil Refinery Expansion in Ruakaka , to working on the construction of the tallest building in New Zealand in 1990, Raewyn reflects on these jobs with fondness. “My first construction job when I left college was with Downer Construction on the Wellington Terrace Tunnel project, before working in the engineering department in their Head office”. Now Downers are a customer of hers.

Today Raewyn owns and operates her own business which she started in 2003.  Based in Drury, Auckland, Sharp Concrete Cutters & Drillers offer a comprehensive range concrete sawcutting and drilling services Auckland wide. “I started with one van, now we have 8 vans on the road and growing.” Sharp offer a wide range of sawcutting including various specialist concrete cutting services such as electric floorsawing, hydraulic handsawing, and ringsawing for internal work where petrol powered machines are a health and safety issue.  Diamond core drilling services range from as small as 12mm diameter to 500mm dia holes.  Raewyn says “from drilling 1 metre deep holes in the base of the old Victoria Park Chimney for strengthening to sawcutting and installing cabling on the Kingsland Railway Station for the Snapper card rollout prior to the World Cup every job is different and has its own challenges.” Working in a big city like Auckland means people and traffic, and both of these need to be regularly managed.

Our environmental slurry control vacuum truck is an important part of our business, and this helps us offer our customers a “one stop shop” service when it comes to booking and completing jobs, particularly on public roads and highways.  Our vans also carry smaller slurry control vacuum tanks that hold 600 litres.  These are practical for smaller residential jobs where slurry is an environmental hazard and has to be managed.  Gone are the days of just tipping it down the drain.  We collect it and dispose the slurry to an environmental waste facility.

Raewyns’ company has been a member of the New Zealand Concrete Sawing & Drilling Association for 8 years, and she has been President from 2010 to 2013.  Raewyn says being President of a male dominated industry group was a bit nerve racking at first.  The Association started in 1986 and is still going strong.  Being a member means you are serious about what you do, and committed to sharing and learning from other members.  We have about 32 members nationwide and several Associate members.  Over the years we have developed and produced a member manual guideline with a code of practice, a code of ethics, safe operating procedures for equipment use, and an environmental pollution control policy.  We also run ‘concrete cutting specific’ safety courses for our members.

Raewyn says “it is important to have honesty and integrity in all areas of your business, and that makes for better relationships between staff, customers, and suppliers”.   This payoff is evident when the first 3 people I hired still work for me.  The construction industry is known for its “boom and bust cycles” and it is with the loyalty of my staff, long term customers and suppliers that has helped us to where we are today.

Exposed Aggregate Finish

Many customers, wanting a slightly different look, opt for an exposed aggregate finish.  This process removes the top layer of fine concrete, thus exposing the underlying aggregate.

While there are a number of ways this can be achieved, the most common, and most efficient is simply water blasting off the top layer.

Sharp Concrete Cutters and Drillers are regularly called in by concrete placing contractors (as well as our other main contractors) to expose the aggregate.  To do this, we send out our slurry control truck which is fitted with a high power water blaster.

But the question remains – what happens to that fine layer of concrete that is removed?  That top layer contains slurry and is highly toxic.  Our slurry control truck is engaged to collect the runoff and thus eliminating the potential environmental hazard.

Concrete cutting and drilling produces slurry.  

Slurry contains calcium carbonate, is a base with a high ph level, is detrimental to marine flora and fauna, and so it is illegal to dump it into sewers, storm water systems, or natural waterways. As such it is important that slurry control is put in place.

Sharp Concrete Cutters and Drillers Ltd provide a comprehensive slurry control service.

With its dedicated slurry truck, Sharp Concrete Cutters and Drillers Ltd can remove 2500 litres of slurry.  The truck also holds 1000 litres of water and has a high-pressure water blasting unit.  Our truck has also been used in aggregate exposing and acid washing applications. 

We also have a number of 600-litre slurry tanks and are committed to leaving every job clean and tidy.

Drilling Through a Finished Wall

There are times when clients require drilling through a finished wall.

In situations like that, slurry needs to be eliminated.

As can be seen from the images below, there was no slurry on either the finish or exposed concrete wall.

Drilling Through a Finished Wall

Drilling Through a Finished Wall

Core drilling techniques are used when tradespeople require precise, circular holes drilled.

Any hole, from 12mm to 500mm diameter, can be achieved to make openings for plumbing, electrical, telecommunications

 

Stitch drilling is a process where we drill a series of overlapping holes in order to make openings.

Man Hole

With Auckland’s ever increasing infrastructure demands, service access is something that’s often needed after the fact.  Man hole covers are a prime example of this kind of aftermarket demand.

See below for an example of how Sharp Concrete Cutters and Drillers core drilling service can be applied to Auckland’s ever increasing infrastructure demand.

Lift Shaft – Ring Saw

Lift Shaft – Ring Saw: This expansion to existing lift shaft was achieved using a ring saw.

Lift Shaft – Ring Saw

Using a petrol powered ring saw has a range of applications.

Typically, a ring saw can cut deeper than a hand saw which allows for cuts to be made in thicker panels and slabs.

This piece of equipment can also be used to cut through thick concrete pipes.
