Tri-Star works with AfriSam on top-drawer Infinité apartments

As the readymix concrete supplier of choice, AfriSam will supply approximately 17 500 m3 of readymix concrete for the construction of various structures of the Infinité Apartments

Tri-Star works with AfriSam on top-drawer Infinité apartments

A glittering new residential development featuring fluid spaces, transparency and the spectacular use of glass is under construction in the suburb of Bedfordview, east of Johannesburg, with Tri-Star Construction as lead contractor and AfriSam supplying the readymix concrete.

Developed by Fatasy Property, Infinité is a luxury ten storey block of 198 high specification apartments, most ranging in size from 40 m2 studios to 79 m2 two bedroom units. Eighteen of the units will be the exclusive penthouses, complete with double volume areas to further enhance the sense of spaciousness and elegance.

In one of the largest pours that the contract will require, AfriSam delivered and poured 590 m3 for a basement slab during September 2017

Infinité will be the first high rise residential offering in the Bedfordview area, boasting both north facing and south facing apartments. The generous facilities will include two levels of underground parking, meeting rooms, a gym, an outside pool and a club house.

Glass balustrades all around the building and on every floor add to the modern design which, according to the architect Adrian Maserow of AMA Architects, “embodies the ambition of contemporary architecture”. The style is further enhanced by light colours with muted hues of charcoal, stone, brushed steel, oak and iceberg white.

Construction

Numbers of workers on site will peak at about 460, including sub-contractors and their staff

With earthworks kicking off early in 2017, Tri-Star Construction was on site to start piling work in May 2017 and full construction activities began in July the same year. The company will take the building right through all the construction phases to final finishes.

We are building in three sections – west, centre and east,” Tri-Star Construction contracts manager Daniel van Jaarsveld, says. “While these are being done almost concurrently, we will advance with the core section – where the lifts are situated – slightly ahead of the east and west sections, which will then follow together.”

The partnership with AfriSam on this project began with the supply of readymix for the over 110 pile caps – each taking between six and nine cubic metres of concrete – and the foundations for the building. AfriSam will supply some 17 500 m3 over the course of the project, according to AfriSam sales consultant Liza Rossouw, supplied from the company’s Prolecon and Spartan plants.

The size of the project also requires substantial quantities of reinforcing steel. Over the duration of the construction period, about 2 700 tonnes of reinforcing bar will find its way into the concrete elements of the structure

Construction of pile caps, columns and basement floors is followed by the transfer slab on the first floor. The concrete specified for the 1,5 metre by 2 metre beams is 50 MPa, while the columns demand 40 MPa strength. In one of the largest pours that the contract will require, AfriSam delivered and poured 590 m3 for a basement slab during September 2017.

The size of the project also requires substantial quantities of reinforcing steel. Over the duration of the construction period, about 2 700 tonnes of reinforcing bar will find its way into the concrete elements of the structure.

Where special concrete mixes are required – such as for the swimming pool deck – AfriSam will create the required mix at the plant and deliver to site. In the case of the pool, the roof and some areas on the first floor where garden areas are planned, a chemical admixture will provide the concrete with improved waterproofing qualities by reducing its porosity.

Concrete quality is, of course, high on our agenda and we test every pour ourselves, as well as make use of the services of a well-respected and independent service provider,” says Van Jaarsveld.

Infinité will be the first high rise residential offering in the Bedfordview area, boasting both north facing and south facing apartments

AfriSam conducts tests for our own purposes,” says Rossouw. “This is a crucial element of the quality control for which we are well-known in the readymix concrete sector, helping customers to safeguard their own standards and effectively manage their risk.”

The main structure will be completed by June 2018, while brickwork will continue until October; about 4,3 million bricks will be laid in the building of Infinité, along with the consumption of 38 000 bags of cement which will be batched on site mainly for bricklaying and plastering purposes. The maximum height of the building is scheduled to be reached in September 2018.

With our focus on the quality of our work and the safety of everyone on site, we place high importance on working with sub-contractors with experience, in whose ability we have the highest confidence,” says Van Jaarsveld. “High quality finishes are non-negotiable in a contract of this nature, as the client and end-consumer will be expecting flawless results in every aspect of their living area.”

The quality finishes include Bosch and Hansgrohe appliances and fittings. Large windows open each living space to expansive surrounding views.

The sub-contractors will be responsible for applying 63 000 m2 of plaster on the walls of the building, all to the high standards expected by the contractor – as well as 180 000 m2 of paint. Numbers of workers on site will peak at about 460, including sub-contractors and their staff.

Among the challenges when building this scale of project in a residential suburb, he says, is the potential disturbance caused by construction noise.

It is therefore vital for us to engage continuously with residents of the area, so that we can do all we can to accommodate them, while maintaining our construction schedule,” he says. “There are particular demands of the building process, however, that can make this difficult. When pouring large slabs, for example, we still need to power float the concrete for some time to achieve the desired finish and this may extend well over normal working hours.”

The main structure will be completed by June 2018, while brickwork will continue until October 2018. The maximum height of the building is scheduled to be reached in September 2018.

What is important, he notes, is to communicate with residents well in advance, and to keep the noise levels as low as possible and within working hours as far as can be arranged.

We work to provide a highly professional and hands-on service to our clients and stakeholders, whether the project is large, small, simple or complex,” says Van Jaarsveld. “We therefore rely on the consistently stringent standard of readymix concrete delivery from AfriSam, as they complement our own commitment to quality, safety and best practice.”

Dangote Cement elbows in on PPC takeover deal

According to the following report by Bloomberg news agency, Dangote Cement has approached PPC about a takeover deal, signalling the start of a possible bidding war for South Africa’s biggest cement maker after an earlier offer led by Canada’s Fairfax Financial Holdings.

Dangote has told PPC’s board that it’s interested in buying “the entire share capital,” the Lagos-based company said in a statement to the Nigerian Stock Exchange. “This communication is still at the preliminary stage,” the cement maker said.

The approach by the company owned by Aliko Dangote, Africa’s richest person, follows a joint offer from Toronto-based Fairfax and PPC’s domestic rival AfriSam. While PPC will consider all bids, the Public Investment Corp., its largest shareholder, supports a tie up with AfriSam and Fairfax. LafargeHolcim, the world’s biggest cement maker, is also monitoring PPC’s situation.

At the time PPC shares rose 2.4 percent to 6.10 rand, increasing gains in the past month to 62 percent and valuing the company at 9.7 billion rand ($738 million). Dangote, listed in Lagos, has a market capitalization of about $10 billion.

Dangote has the capacity to pull the deal off,” Pabina Yinkere, an analyst at Vetiva Capital Management, said by phone from Lagos. “It is a very liquid company with a very strong cash flow. It is a good strategy that would help Dangote consolidate leadership in the South African market.”

A takeover of PPC by Dangote would combine two of Africa’s largest cement makers with operations throughout the continent. It would also scupper the South African company’s plans to merge with AfriSam, a deal that the PIC wanted to get through to create a national champion.

Africa’s biggest money manager owns about 11 percent of PPC, according to data compiled by Bloomberg. It’s also the biggest shareholder in AfriSam with about 60 percent.

AFRISAM READYMIX FOR UNIQUE DYNAMIC’S DROOGHEUWEL RESERVOIR PROJECT

On site at the Droogheuwel bulk water reservoir in Randfontein are Ultimate Dynamics project manager, Pieter van der Merwe (second to left), with the AfriSam team with production team leader Mark Wernich (second to right), territory manager Antonio Benjamin (right) and site and service coordinator Wikus Visagie.

AFRISAM READYMIX FOR UNIQUE DYNAMIC’S DROOGHEUWEL RESERVOIR PROJECT

Gauteng continues to be an urban magnet drawing job seekers from far and wide, making the Droogheuwel municipal bulk water reservoir in Randfontein a vital piece of infrastructure to keep sufficient water flowing to the growing area of Randgate.

Hard at work on this 20 megalitre reservoir is the Stilfontein-based contractor Ultimate Dynamic, supported with concrete from construction materials leader AfriSam. The project is due for completion in March 2018.

According to Pieter van der Merwe, Ultimate Dynamic’s project manager, the 47,6 metre diameter structure, with a wall thickness of 500 mm, will require about 2,000 cubic metres of water-tight pump-mix concrete with a strength of 40 MPa.

“After the contract was awarded in December 2016, we started preparation on site in January and were ready for our first concrete pour in April,” says Van der Merwe. “We are now about a third of the way to completion, and are busy on the third lift (or level) of the reservoir wall, which will require eight lifts to take it to the required height of almost 13 metres.”

Readymix is being delivered from AfriSam’s Technikon plant in its six cubic metre capacity trucks, with each pour comprising about 60 cubic metres – or ten trucks of readymix. Concrete is raised and deposited into the formwork moulds by a truck-mounted boom pump with a reach of over 40 metres, according to AfriSam production team leader Mark Wernich.

“We currently deliver on average once every seven working days, and our plant is conveniently located less than 25 km from site,” says Wernich. “Our production capacity and specialised equipment will also allow a continuous pour of about 380 cubic metres for the roof of the reservoir, once the walls are completed toward the end of the year.”

Van der Merwe says the project covers the reinforced concrete construction of the reservoir walls and roof, as well as all pipes, valves, access manhole doors and step ladders. It also includes the inlet and outlet chambers for the reservoir, pump rooms and the access road from the existing tar road nearby.

“It has been a smooth operation working with AfriSam,” he says. “We place our site orders with Ultimate Dynamics head office, which contacts the AfriSam call centre. The concrete is then dispatched from the plant in Technikon in Roodepoort, and it has all proceeded like clockwork.”

He highlights the value of AfriSam’s quality control function, which includes taking their own concrete tests on site with every delivery, ensuring that the correct strength of concrete has found its way into the structure.

“It is vital that tests are conducted on every batch, and the results carefully recorded, so that our client can be assured of the integrity of the work,” says Van der Merwe. “With a major structure like this, holding such a large volume of water, there needs to be great attention to every detail.”

Wernich says that AfriSam’s quality systems are a key element of its offering to customers.

“Even when our customers do their own testing, we also test and keep records that they can refer back to if there is ever any query about any particular batch of readymix delivered,” he says. “AfriSam’s plant laboratories – based at our cement, aggregate and readymix operations – ensure ongoing process control testing on all our products.”

Once the Droogheuwel reservoir is complete, the pipeline to feed the new reservoir will be laid over a distance of about seven kilometres through the town of Randfontein, linking it to an inlet pump station on one of Rand Water’s main lines. Water from the reservoir will then be pumped from the outlet chamber on site to the pressure tower about two kilometres away, from where it can enter the reticulation system serving the surrounding area.
