The contract was successfully completed with a gratified client and excellent quality work.
South 32 South Africa (the client) require the specific services of Esor Construction to provide essential infrastructure for the establishment of the new mini-pit mine.
The Khutala Mini Pit coal development lies approximately 7km south of Ogies Town in the Mpumalanga Privince of South Africa. The project involves the provision of infrastructure required for the establishment of the KSA Mini Pit.
The Khutala Mini Pit Project will mine coal over a period of 3 years starting the delivery of coal to the run of mine (ROM) stockpile within a few months of the start of the project. The necessary infrastructure to be constructed by Esor is as follows :
* HDPE lined pollution control dam (PC dam)
* Access roads
* Haul roads
* Dirty water concrete lined drains
* Concrete works
* ROM terrace with an environmental GEO liner
The life of the mine is currently set at 3 years, but most of the infrastructure will be required for the future extensions of the mine.
The contract duration for this project is 8 months. During this period, critical construction elements have been identified to be able to hand over these sections of the work to allow coal to be hauled from the pit to the ROM stockpile on site. This requires the PC dam, the Pit Haul Road and the ROM terrace to be handed over first.
The Mining haul roads are 26,5 meter wide and will carry haul trucks of up to 250t. These roads are generally raised above the natural ground level and are constructed with culverts to pass storm water underneath. The storm water run-off from the mining haul roads are collected and transferred to the PC dams.
All the roads have gravel wearing courses and layer works to provide support for this heavy traffic.
There is one pollution control catchment and storage dam divided into two sections to be constructed on site. This dam is excavated in the natural soil, but also have walls of 3.5 meter above the natural ground level.

This project was awarded to Esor Pipejacking division in March 2013. The project required 21 jackings within a 6 month period. The J10 pipeline, replacing the outdated J8 pipeline, will be 14km long starting at Simon Bekker Rd in Germiston and ending at Reservoir Rd in Boksburg. Our scope also includes 1 stormwater canal crossing, 2 rail road crossings, 1 un-utilised railroad cutting, and 17 road crossings. The project was completed in December 2014.
Progress on the Wonderboom/Rooiwal bulk pipeline has advanced considerably with the recent completion of three important underground tunnels.
Pretoria motorists driving along Steve Biko Drive and Lavender Road over the past three months, would have been blissfully unaware that a team far beneath their wheels was digging one of the biggest underground precast culverts in South Africa.
According to project manager Anton Naude, each tunnel is 4,9 metres high and 2,7 metres wide, while the tunnel under Lavender Road is 40m in length supported by no fewer than 32 precast concrete structures, weighing 11 tonnes each.
"A hydraulic jack was used to push each structure into the tunnel which is wide enough to accommodate two small cars side by side. A significant feature of the project was that the pipeline was laid without any disruption of traffic on the city's main arteries," he said.
The pipeline is a key component of Pretoria's 50-year development project and will supply water to Rainbow Junction and other industrial and residential growth areas to the north of the city. The R130 million project began in 2013 and is scheduled for completion in 2015.
The O6 project was awarded to Esor in May 2015 with a total of 9 jacks.
Since May 2015 we have finished three more jacks at Palmiet 06 line. These three jacks were handed over to the pipelines crew to push the steel pipe through the concrete sleeves. Our Original scope of work was to construct 9 pipe jacks on Portion B, but we were awarded an additional pipe jack on Portion A of the project. Progress to date on the remaining jacks is 7/91m at J8, 9/92m at J13 and 70/118m at J14. This means we still have adequate secured work on this line to keep us busy for the calendar year.
Typical of the area, we encountered a lot of mud and water at Jack 13 where we had to do piling to prevent mud slides and collapses. This however did not improve the conditions to prevent the mud slides and collapses. The soil was so saturated, that the 3m OD concrete pipe just dug into the soggy soil at the bottom and instead of jacking up, the pipe went down under its own weight.
We, as Esor, had to re-design the jack alignment and thinking on our feet it was decided to stop both jacks 13 and 14 than was planned to go under the N3 and Jack 14 under the secondary road.
The net effect resulted in an additional 20m VO approved, additional income and extended time in which to carry out the project.
In March 2016 we were awarded Jack 8 and right from the start we had difficulties with SANRAL and the Alberton Municipality. The jack was too close to the road and inside the SANRAL servitude and they wanted it moved. We then suggested 5 meters back and this was on a truck arrest road and the Municipality was not content on breaking up the arrest road in the event that it was needed during construction. We then requested for an open cut across the arrest road which was also denied. Eventually the jack went from a 53 meter jack to a 91 meter jack to satisfy every body’s needs.
This decision however brought additional problems that was not anticipated at the time. The pit and 15 meters of jacking is in backfilled ground conditions. With the heavy rains over the past few weeks we encountered numerous collapses in front of our pipe and every time we need to stop and make safe with nails and gunite before we can excavate further. The face of the jack is now under the arrest road and we have entered more solid rock and hopefully we will encounter no more collapses.
The Project's overall completion date is targeted for September 2016.
As we are targeting selected African countries, the award to Pipe Services of these 2 projects fits our strategy and reduce our risk and dependency on the South African market.
The Palapye Major Water Supply contract that include 6 pipe jack crossings below existing roads and railways. The sleeves that will be used is 1800mm and 1500mm inside diameters with a total jack length of 217 meters.
The Mahalapye Major Water Supply contract include 4 pipe jack crossings below existing roads and railways. 1800mm and 1500mm diameter sleeves will also be used with a total jack length of 162 meters.
Treated Water will be running in the newly installed pipes from Water Treatment Plants. The Palapye ring will be running from Botswana International University of Science and Technology water treatment plant whilst Mahalapye ring will run from Morale Hills water treatment works.
We have just completed the first crossing of 34m in Palapye, starting another crossing under a railway line to cover 20m and continuing with the 1st Mahalapye pipejack for the project running under neath A1 road covering 61m and expecting to complete by end March 2016. The remaining pipejack crossings will all be completed by end of August 2016.
We completed site establishment in early December 2015 at the R59 Highway and Johan Le Roux corners. The client is Midvaal Municipality with consulting engineers Gibb and Esor as the main contractor.
The R59 consist of 5 jacks of which 4 jacks are for sewer lines and one jack is for the water main line. The 5 jacks consist of the following lenghts; the Highway is 211m long and will have three inter jack sections to maintain an even pressure on the jacks and to prevent the pipe from seizing up. The end of the jack will also be the start of the Johan le Roux jack that will start about 3m higher than what the Highway jack will end on. The Johan le Roux crossing at 106m long willl end inside an existing sewer mainhole to be connected on the old line. The third jack is the water main line and is situated about 5km from the other two jacks at Aandblom Street and is also jacked underneath the R59 highway for a total distance of 98m. All three these jacks are currently in progress.
The 4th jack will be underneath the railway line at Meyerton and will be 84m long. The 5th jack will be from the same pit as the Highway jack and is jacked underneath a property for 52m. This jack will also end inside an existing hole within the sewer line to be connected with the existing sewer system. All 5 jacks are spected as 1200mm IS pipe, making it very strenuous on the legs of the workers going to the front of the face. Ventilation will be a big priority and hydration of the workers will be continuous. Only two workers can be at the face at a time as the working space is so small. As the main contractor on this project we will also be inserting a HDPE 500/600 OD pipe through the sleeve pipe and will build manholes at the jacking pits.
After spending over 12 months inside a 1200mm diameter pipe, we managed to complete the over 80m jack and see dayling on the 8 March 2017.
With our tireless efforts in mind, the Client has agreed to award some additional works to Esor which include additional manholes and installation that is successfully underway.
The project is estimated to be complete by the end of April 2017.
"The City of Cape Town approached Tuboseal in 2013 to investigate the possibility of rehabilitating the pipeline and utilising its much-needed capacity after many years of being degraded beyond use."
A CCTV inspection was the first and vital step in the rehabilitation process that ensued. The city conducted several viability studies and finally appointed Aurecon Consulting Engineers to manage the trenchless rehabilitation project, comprising the CIPP lining of more than 3,300 metres of bulk sewer pipes ranging from 800mm to 1200mm in diametre, crossing underneath the N2 freeway and Baden Powell Drive.
Esor Tuboseal was awarded the project at a competitive rate and immediately began the careful logistical planning required in an environmentally sensitive and often inaccessible area.
The construction programme was expedited to ensure cleaning, final design, material manufacturing, shipping lead times and installation happened concurrently. The dovetail effect of these activities placed the project firmly on track for completion well ahead of the programme and the (hopefully) rainy Cape Town winter.
The work itself was not without its challenges, but it did vindicate the depth of professionalism demonstrated by Esor Tuboseal and its commitment to preserving the natural environment.
"The rehabilitated pipeline runs alongside an ecologically sensitive wetland and the use of trenchless technology ensures that the ecological impact of the project is negligible. Already 40% complete, we are on track to complete 3,300 metres of pipeline renewal without any significant excavations required."
Esor Tuboseal also adapted its hot water curing process to incorporate a high-performance water cooling system, which enables the recycling of process water and a saving of more than three million litres of drinking water amid critical water shortages in the Western Cape.
Apart from delivering a workd class product on this project, Esor Tuboseal set some audacious goals of 'safety first', 'first time right' and an unwavering resolve to maintain integrity with all stakeholders.
Our pipelines division is well on course to completing the installation of a pipeline connecting the Xonxa Dam to the Queenstown water treatment works.
This Eastern Cape project is a component of the greater Xonxa Dam transfer scheme and bulk water supply project commissioned by the Chris Hani Municipality to increase Queenstown’s bulk water supply.
The 22,3km DN 600 cement-lined steel conduit will not only help relieve present water shortages within the urban area but will provide a much needed supply of potable water to residents of underdeveloped rural areas.
An extensive range of tasks are associated with the project. Among these are site clearance, connections to the pump station delivery line and reservoir intakes as well as the execution of road and river crossings. The route also includes two above-ground sections, and traversing a ridge – a vertical gain in height from the pump station of 400m.
Important environmental and cultural considerations were the identification and protection of two very old trees and the preservation of bushman paintings and a site that was used to make stone tools.
The team, which is expected to complete the project by September, is made up of 30 core Esor Pipelines personnel, including operators, welders, foremen and supervisors. These numbers are augmented by 165 local recruits who have received training in pipeline construction.
The cooperation between contractor and client has been excellent, says Director Arné Rheeder.
"This is our first project for the Chris Hani District Council and we are delighted to be partnering with such a progressive and forward-thinking organisation on an important project like this."
We have been awarded the Construction of the F46 Pipeline: Earthworks, Pipe laying and Associated works for the construction of a 4km long 1424mm ID (12mm thick) steel pipeline from Whiteridge Waterval to the Weltevreden Reservoir awarded by Rand Water.
The pipeline was awarded in two sections where Esor Construction will construct portion A and Maziya General Services will construction portion B. Under Portion A, Esor Pipe Services have been awarded 4 road jackings of which 1 is complete and the remainder expected to be completed before the end of March 2017. The Jacking at Maluti street was increased from 17m to 29m to pass existing structures which obstructed the pipeline route. The jack closest to the Weltevreden Reservoir is being extended from 21m to 75m to mitigate the uprooting of a major storm water pipe.
Additional jacking of 30m is planned, next to a residential building where excavation for the pipeline cannot be done, but we can provide the solution.
Construction activities will start the 3rd May 2016 and the expected completion date will be 31st October 2017.
