WORLD DAY FOR SAFETY AND HEALTH AT WORK – 28 APRIL 2016

WORLD DAY FOR SAFETY AND HEALTH AT WORK – 28 APRIL 2016

Today, World Day for Safety and Health at Work, is intended to focus international attention on promoting and creating a safety and health culture at work and to help reduce the number of occupational-related fatalities,injuries, and diseases.

It is significant that the 28 April is the day after the day on which South Africa celebrates the anniversary of the first democratic elections. Significant, because there is no real freedom, including security and human rights, till the threat from injury and disease is removed from workplaces.

South African construction continues to receive unfavourable media coverage due to trench collapses,building, support work, and slab collapses, fatalities, injuries, disease, and damage to public property. Furthermore, the focus is still on safety; health and ergonomic issues receiving limited or no attention.

Although there is a need for a paradigm shift from compliance to better practice, including the addressing of primary health issues, there is still the elementary need for basic compliance.

Based upon extensive research, publishing, course, seminar, and workshop development, conference organising, lecturing, community service, and professional registration and association, the author advocates the following to realise substantial change in South African construction health and safety (H&S):

 “Respect for people” is a prerequisite for the value below;

The value “People are our most important resource” (value = constituent of H&S culture);

Leadership in terms of H&S;

Management commitment, participation, and involvement in H&S;

Multi-stakeholder contributions to H&S – architects, clients, contractors, engineers, interior designers, landscape architects, material manufacturers and suppliers, project managers, quantity surveyors, and unions;

Optimum H&S culture, among other, a vision of fatality, injury, and disease free projects, and a goal of zero deviations as opposed to incidents or accidents;

Comprehensive H&S education and training of all stakeholders (designers included);

Competence accompanied by, among other, appropriate values and an exacting philosophy – the core competencies (self-image, traits, and motives) differentiate between superior and average performance i.e. at best the surface competencies (knowledge and skills) can only realise average performance;

Optimum status for H&S – greater than or at least equal to that afforded cost, quality, and time;

Sound construction management (bona fide as opposed to pseudo) i.e. management of construction by construction managers;

Integration of design and construction in general, but especially in terms of H&S;

Implementation of documented quality management systems in design and construction;

Implementation of documented H&S management systems in design and construction;

Focus on H&S regardless of circumstances – H&S is a value, not a priority;

Elimination / Mitigation of ‘excusitis’ (mind deadening thought disease manifested in excuses), and

Consciousness and mindfulness – constant cognising with respect to the surrounding environment, attention relative to H&S, and mindful with respect to the implications of actions or omissions.

When the going gets tough…

When the going gets tough…

The tough get going…

And that’s just what we in the construction sector are doing.

We South Africans are renowned for our resilience and survivability in the face of adversity. And to that I would like to add innovation.

Roy Mnisi, Executive Director, Master Builders South Africa

We have a myriad obstacles thrown at us ceaselessly in these difficult times, including dodging the junk status allocation; simmering political uncertainty; crisis in the steel sector; low economic and employment growth; rising inflation and higher interest rates; ever shrinking margins; non-payment issues; and sadly, the crippling drought.

Add to this the frightening rate of retrenchments taking place in our sector, estimated at 20 000 or more over the past six months, not only by the so called Big Five construction companies, but also small and medium sized construction and contractor companies across the country. And the attrition is set to continue. In this vein IOL reported in December that “Unions had been overwhelmed with retrenchment notices, with unemployment edging closer to 40 percent,” and that “job losses in mining, construction, manufacturing, agriculture and the farming sectors are projected at more than 200 000 into 2016.”

Yet through this maze of seemingly insurmountable difficulties, a Master Builder in the Western Cape, Garden Cities developers, have demonstrated that innovation, dedication and collaboration can deliver outstanding results in the establishment of private/public sector partnerships (PPPs).

This initiative, led by John Matthews of Garden Cities, has resulted in the launch of the Greenville housing project, with the first of 70 000 houses having been delivered (read more here http://www.sabuilder.co.za/2016/04/19/greenville-garden-city-launches-ahead-of-huge-population-influx/).

We as Master Builders must sit up and take note of such vibrant go-getters, join hands with municipalities and government departments in far closer collaboration to use working examples of PPPs across government housing projects, infrastructure and civils to produce future models with which to drive our National Development Plan (NDP).

Let us work together with our follow construction industry bodies and member companies, to bring our combined resources to bear on the orchestration of, and the setting up and driving of these PPPs, building them as the successful projects our industry and nation so desperately needs.

Making the NDP work is up to us.

Symbiosis in concrete solutions creates near perfect seamless flooring

South African Builder talks to Angus Ryan, Brett Meadway and Xavier Destrée about their leading edge technology in steel-fibre reinforced, super-stable and super-flat seamless concrete flooring produced through the symbiotic relationship between three companies: Concrete Laser Flooring (CLF), AfriSam and Primekss PrimeComposite.

8-CLF-PRIMEKSS-DSC_8539

Angus Ryan – manager at CLF; Xavier Destrée – consultant to ArcelorMittal and legendary innovator in seamless concrete flooring; and Brett Meadway – sales manager, CLF-PrimeComposite

CLF is the exclusive agency in Southern Africa for Primekss,” says Ryan, manager at CLF. Primekss, based in the city of Riga, Latvia, was founded in 1997 and is renowned world-wide for its specialised research and solutions in concrete design – in particular, high strength seamless concrete flooring for modern warehouses and distribution centres.

Xavier Destrée is a civil engineer and a legend in this technology. Destrée has for many years been a consultant to ArcelorMittal in this technology and is the driving force behind the technical development and bedding down of the process in Europe. In addition, he authored the patent for making joint-free flooring and plays a key role in global implementation of operations.

The concept of using steel fibre in concrete was first tested in 1908 and was originally patented in Paris,” says Destrée. “But very little was done until 1980 – and today, the technology has been perfected, whereby steel fibres 0,75 mm x 50 mm, produced and supplied by ArcelorMittal, are homogeneously blended with the concrete at the time of pouring. This process, together with careful design and application of admixtures, virtually eliminates shrinkage,” continues Destrée. “The strength is also enhanced to the point where no steel rebar is required; shrinkage is virtually eliminated; and seamless concrete flooring can be cast at 100-130 mm thick – half the traditional thickness of 300-400 mm.

The savings are significant on every front,” says Destrée. “Less concrete is required – by half; and in terms of green construction the CO2 content is halved – keeping in mind that concrete is the second highest culprit in CO2 emissions at 1 ton of C02 being produced per ton of concrete; and of course the high level of quality results in a floor requiring little or no maintenance.

On-site production begins: AfriSam readymix trucks deliver the concrete to site; a DC pump and fibre blower blend the steel-fibres into the mix

CLF-PrimeComposite is a revolutionary high-tech approach to concrete production. Using high dosage-rate steel fibre reinforcement coupled with anti-shrinkage concrete and special quality-management techniques, we are able to concrete that is tougher, stronger, crack-free and ecologically friendly,” says Destrée, who is of the opinion that steel-fibre reinforcing of all concrete used in construction should be mandatory.

On the operational front, Brett Meadway, sales manager for CLFPrimeComposite explains: “The synergy between our three companies enables us to achieve remarkable results not otherwise possible. The expertise and depth of research in concrete offered by Primekss, combined with the operational and installation expertise of CLF, and the production and logistic capabilities of cement manufacturer AfriSam, all combine to provide world class concrete flooring of unsurpassed quality and functionality.”

R&D is undoubtedly the most important part of the system,” says Meadway. “And the most important output focus is clearly on quality of the highest standard.”

CLF-PrimeComposite offers a five year warranty on its seamless concrete flooring, which can be extended to 10 years with maintenance agreement. “CLFPrimeComposite will stand by their clients all the way,” concludes Meadway.

3-PRIMEKSS-4 PART

1. In our laboratories in Latvia we analyse samples of local aggregates, sand and cement previously shipped to us by CLF. 2. We then produce a mix design together with AfriSam, suited to the specific project in hand. 3. On-site production begins: AfriSam readymix trucks deliver the concrete to site; a DC pump and fibre blower blend the steel-fibres into the mix; the CLF laser screed machine levels the floor during the continuous pour. 4. All processes in “3.” are closely monitored in real-time by CLF on a specialised iPad system. This is monitored by lab technicians in Riga as well as by the client. Any adjustments required to the mix are made on the spot.

Greenville Garden City launches ahead of huge population influx

Master builders at their best: Garden Cities developers is a member of Master Builders Association – Western Cape.

6-greenville first house handover

Minister Bonginkosi Madikizela and Sean Stuttaford (Chairman of Garden Cities) (on the left) were on hand when Zamile Wildon Jiya (third from left) received his house at Greenville Garden City, together with Project co-ordinator Thembi Sithole, John Matthews, CEO of Garden Cities, Premier Helen Zille and Councillor Benedicta van Minnen

The new suburb in the Fisantekraal district near Durbanville, Western Cape – Greenville Garden City – was officially launched in March by the Premier of the Western Cape, Helen Zille, with the delivery of the first of the planned 17 000 houses.

To be developed in phases over the next 16 years, Greenville Garden City is a public/private collaboration between Garden Cities (1919) the oldest and largest developer of suburbs in the Western Cape, and the City of Cape Town.

The project, which is set to revolutionise housing development through the application of innovative materials and technology that exceeds the performance of traditional construction methods and significantly accelerated speed of construction, will set a very long-term standard.

John Matthews, Group CEO of Garden Cities and President of Master Builders Association – Western Cape, says that Greenville Garden City is his company’s most important project in its 97-year history. “There will be a wide variety of residents from different economic sectors within the 767 hectares, all of which will be recognisable as a Garden Cities development with the quality and aesthetics which that implies,” said Matthews.

The biggest challenge for the Cape Town metropolis is the estimated influx of an additional 700 000 people by 2030,” said Provincial Minister of Human Settlements Bonginkosi Madikezela.

His view was endorsed by the Premier when she said “South Africa is not a place for sissies. We have to roll up our sleeves and vasbyt – not look for the easy solutions. The irony is that the projects that do the most good are often those that are the most difficult to deliver;” referring to disputes that often arose from different interest groups that could disrupt or even derail enterprises.

The delivery of Greenville Garden City has taken eight years of planning, through many stages and changes.

Initiated by the nearly 100-year-old residential suburb developer Garden Cities, the project finally matured into a public/private partnership with the City of Cape Town, through which the government grants to beneficiaries are administered. The company owns the 767 ha of land where an entire infrastructure, including 12 primary and high schools, an integrated transport hub and a range of community facilities will be built.

It will be responsible for the development through a project team of building professionals including facilitation, financial and legal support.

John Matthews, Group CEO of Garden Cities, said that the project has been the highest priority for his team over the past eight years. “Greenville is our fast-realising dream of restoring dignity to our people,” said Matthews. “It is our opportunity to make it a means of true upliftment and better social conditions.” More than 110 local Fisantekraal residents are involved in the construction of the project.

The schedule is to deliver 40 houses per month, constructed using the innovative Benex blocks, invented in Australia and now manufactured at a nearby factory in Epping, where previously unskilled and unemployed local people are producing the product.

Speaking of the Benex Blocks and other highly efficient materials used in the construction of the houses, the Premier said that the blocks were a metaphor for the perfecting and export of new technology in South Africa.

Councillor Benedicta Van Minnen, Mayoral Member for Human Settlements’ said in her address that “A truly integrated, sustainable human settlement is being constructed, with all social, economic and transport amenities. This project is an example of how the City of Cape Town wishes to manage its residential developments going forward by locating future residential areas for all income groups in relation to economic and work opportunities.

“We are moving towards a new delivery model. The Greenville Garden City development is in line with our densification policy and our transport-oriented development and integrated human settlements frameworks which is, among others, based strongly on partnerships and innovative solutions to mitigate the challenges resulting from increased urbanisation.”

The project has been described as having national and local award potential and a model for all future private/public partnerships.

SITE PREPARATION WITH THE NEW CAT D6R2

5-Caption Cat D6R2 landscape

The operating weight on the standard D6R2 ranges between 18 984 and 19 448 kg (depending on attachments), the XL version from 19 914 to 19 969 kg, and the LGP unit at around 21 661 kg.

The latest generation Cat D6R2 track-type tractor builds on the reputation of the legendary R-Series and features a new cab, an updated transmission, pilot hydraulic controls and a single twist tiller bar for all directional and speed control.

Speaking to SA Builder, Desigen Naicker, Barloworld Equipment’s product marketing manager tells us: “This model is designed specifically for customers who want a robust, productive machine that’s easy to service, combined with a proven drive train system and fuel efficient engine.” (Barloworld Equipment is the Cat dealer for southern Africa.)

Engineered for demanding work, the D6R2 is purpose-built for construction applications ranging from heavy dozing and ripping, to land clearing, finish grading, trench backfilling, and landfill management.

The D6R2 features a Tier II/Stage II equivalent Cat C9 ACERT™ engine, with different power rating configurations depending on the track system fitted. A Tier III engine is also available.

The standard Tier II powered unit achieves a rated net output (ISO 9249) of 133 kW, compared to 148 kW on the XL (Extra Long) and LGP (Low Ground Pressure) versions. A single stage torque divider sends 70 percent of engine torque through a converter and the balance through a planetary gear set, which translates into more power to the ground.

New features to highlight include an electronic clutch pressure controlled (ECPC) transmission with improved filtration. The Cat D6R2 also has a larger fuel primary filter/separator, which has an increased surface area for greater debris retention and filtration performance. A ‘Water in Fuel’ sensor alerts the operator through the monitoring panel. There are also filter restriction warnings for hydraulic and power train filters.

On the Cat D6R2, independent variable displacement piston pumps have been installed for implement hydraulics and the differential steering motor, passing on higher levels of versatility and manoeuvrability.

Engine throttle speed is controlled by simply using a rotary dial. Setting this dial to Auto Shift activates two additional forward gear speeds and one in reverse.

Auto Shift enables the machine to automatically down shift to the most efficient gear based on load,” adds Naicker. “This contributes to improved fuel savings and increased productivity by selecting the most efficient gear based on the variable blade loads experienced.”

Heavy-Duty Sealed & Lubricated track will be available on all configurations, with SystemOne™ offered as an option for the XL and LGP variants.

Scribante batches for Fourways Mall expansion

4-SCRIBANTE-IMG_2540

Scribante’s mobile batching plant near Fourways, Johannesburg

Over the next two and a half years the Fourways Mall expansion project will see this iconic mall double in size to become the largest in Africa.

Construction commenced in January 2016 with Scribante Concrete contracted to supply the project with the massive amount of 185 000 cm3 of concrete over two years. “We are supplying from our mobile batching plant set up for the purpose just six kilometres from the Fourways site,” said Silvio Scribante, director of Scribante Concrete. “Our responsibility is twofold: to supply 115 000 cm3 of concrete for the columns and beams; and 70 000 cm3 to main contractor, Mota-Engil, who is producing the precast elements on site.”

4-SCRIBANTE-IMG_2520

Sam Maleka, plant manager at the Scribante mobile batch plant

Of particular interest is Scribante’s mobile batching plant. Locally manufactured in Port Elizabeth by Metate Construction, the plant comprises horizontal silos, water supply tanks, conveyor and batch mixer, as well as a high tech control room – all set on axles, ready to “plug-n-play” after transport to site. “Setup of this plant takes roughly a week,” says plant manager Sam Maleka. “Each silo has 100 ton capacity and batching is automated via the control room, through a series of augers and pumps which feed pre-determined amounts cement, fly-ash and water – with great precision – to the batch mixer.”

The aggregates are bin stored and “manually” loaded using a front-end loader to great accuracy following an LED display which shows the exact weight of material required.

All we need to operate is 3-phase power and water,” beams Maleka. “Not only do we have a backup generator in case of power outages, but we pump our own water from a reservoir nearby.”

Consistent quality is key to our operations country-wide,” explains Scribante. “Even though this is a mobile plant we have a full lab facility right here which tests and records details of every batch produced.” It is important to note that Scribante Concrete is a member of the South African Readymix Association (Sarma), and as such is dedicated to quality of supply.

This Scribante plant has an optimum output capacity of 60 cm3/hr, though presently it is running at about 40 cm3/hr as, having been recently set up it’s still in the bedding down stage.

Mix designer is Furio Dinardo – Scribante’s national quality manager; and admixtures are supplied by Chryso and BASF.

A fleet of six readymix trucks is in presently in place delivering to the project. This will increase to suit demand as the project moves into full swing.

CONSTRUCTION UPLIFTS DURBAN COMMUNITIES

AfriSam

AfriSam delivers 600 m3 of concrete to the site every day mainly from its new batching plant in Phoenix

Not only will Dr Pixley ka Isaka Seme Memorial Hospital bolster state health care services in the northern areas of Durban, but the building programme is also transferring skills to communities in KwaZulu-Natal that are in dire need of upliftment.

AfriSam is supplying all of the concrete requirements for the build.

This massive build is being undertaken on behalf of the KwaZulu-Natal Provincial Department of Health by a joint venture (JV) between Aveng Grinaker-LTA Building, the lead contractor, and Enza Construction. The onus also lies on the JV to meet the department’s very strict mandate of maximising the delivery of this infrastructure to benefit the poor areas of Inanda, Ntuzuma and KwaMashu (INK).

The socio-economic requirements of the construction programme have added complexities to an already challenging project. Skills transfer is just as important as completing the hospital in two years’ time – October 2018.

Stuart Meyer, contracts manager of Aveng Grinaker-LTA Building, says the method of construction has been kept as simple as possible to ensure as much involvement by members of the local community as possible.

We had various options to choose from, but we decided to opt for a traditional coffer slab system. It requires handling about 2 400 tons of support work, but it offered the best opportunity to increase the number of people working on site,” he says.

It can best be described as a basic ‘Meccano’ system and, although not the quickest manner of building, it is easy to understand and very safe.”

The installation of the system is being undertaken by 16 members of the community, with the help of nine formwork specialist companies from the surrounding area.

The JV is definitely meeting its objectives with its labour based construction methods considering that there were already 650 people on site in mid-February.

By this time, work had started on stripping and the installation of services. Once the latter is in full swing between 600 and 800 additional hands will be needed. Meyer estimates that there will be about 2 000 people working on the site by the end of this year.

One of the major milestones on the programme will be the completion of most of the structure at the end of August this year – well ahead of the initial deadline of the first week of December. This is before the JV starts locking blocks to begin the major task of tackling the extensive fittings and finishings. In mid-February, work had also started on selecting the sub-contractors to undertake the major works packages.

The building has been divided into 10 blocks – A to J – as well as a K section, comprising the plant room, parking area and towers.

Constructing this 100 metre by 300 metre structure, comprising a lower ground and ground level as well as first and second floors, a plant room, roof and towers, calls for very careful planning. The contractors have to keep to a rigid schedule to ensure production continues unhindered so that final locking up can start in March 2018, the year that the remainder of the structure and services will be completed.

From the outset, we decided to complete as much as possible that we have direct control over early on in the programme, preferably within 18 months. This leaves us with a lot of time to complete the finishings,” Meyer says.

Meeting the two year build deadline

To make its deadline, crews work on between 16 and 18 decks a day, with between five and seven completed in a week. Single shifts are worked, and Saturdays are used to gain time, if necessary. The various aspects of the work are undertaken according to a very strict weekly programme, with each deck broken into 15 different items with set deadlines for completion. “These have to be met at all costs and everybody knows this. There are no excuses to achieve the stipulated outputs,” says Meyer.

AfriSam is supplying all of the concrete requirements for the build. A competitive edge for the largest concrete solutions producer in the country is its large black ownership. This in line with the high Broad-Based Black Economic Empowerment requirements that have to be met on this public-sector contract. For example, one of the key outcomes of the build is that 30% of all sub-contracts are let out to 100% black-owned companies.

AfriSam delivers 600 m3 of concrete to the site every day mainly from its new batching plant in Phoenix, which was established especially for this project. This plant services what is referred to as the P.I.N.K. area which encompasses Phoenix, Inanda, Ntuzuma and KwaMashu. Located a mere 1,5 km away from the project, six readymix trucks are dispatched from this site every day, while three more deliver concrete from its Ottawa operation. This mitigates any risk, should there be an unforeseen interruption at one of the plants.

A total of 43 000 m3 of concrete is being supplied and the building materials producer did all four mix designs for the slabs, suspended slabs and columns.

AfriSam’s Marietjie Thompson says about 80% of the concrete for the structure has a compressive strength of 30 MPa and is designed to cure in 28 days, while 35 MPa concrete is being used for the columns.

She says one of the challenges for the company is co-ordinating deliveries to the site to avoid any delays to the contractor’s tight schedule.

In the beginning, AfriSam also helped the JV manage the arrival and use of various mixes on the site. Bear in mind that the contractor opted to do its own concrete pumping, using its own static and mobile unit.

There are 24 lift shafts and hoists in the structure. Meyer says this aspect of the build is extremely complex and therefore time consuming. To keep production moving, slabs, which are split into two 280 m3 sections, are poured just beyond the first pane of the shafts.

Quality matters

With the core of the workforce comprising unskilled workers, the JV has to keep a close watch on the quality of the workmanship at all times. “We are employing many unskilled people and in the beginning we did experience problems. However, we have managed to resolve many of these over time,” says Meyer.

At present, the project employs about 100 bricklayers who handle 35 000 bricks a day, and 500 plasterers. This aspect of the project alone will require about 500 additional hands over the next four to five months.

In order to ensure transfer of skills a core team, comprising 140 specialist workers, has been divided between the various foremen on the site.

One of the advantages for Aveng Grinaker-LTA Building is its past experience working on building and civil infrastructure projects in the area. Before arriving on site, it embarked on an array of initiatives to ensure community buy-in.

These initiatives have ensured the JV receives immense support from both INK Trust and the larger eThekwini Municipality which will certainly help it meets its targets during what Meyer describes as a “massive year” for Dr Pixley ka Isaka Seme Memorial Hospital.
