Infrastructure

The Patula group of companies was acquired in November 2008 and introduced new sustainable revenue streams for the group by expanding services from sub-surface foundation work to include above-surface civil engineering. The businesses were renamed during 2009 to reflect the single vision and shared values. As of November 2013 the name of the holding Company has changed from Esorfranki Limited to Esor Limited.  Esorfranki Civils then became known as Esor Civils.  Subsequent restructuring took place at the end of the 2014-2015 financial year and the Esor Civils division was amalgamated into Eosr Construction.  Infrastruture is now one of Esor Construction's product offerings.

Providing civil engineering construction services since 1995, Infrastructure specifically focuses on road building, mining and township infrastructure work, water and sewerage reticulation contracts and concrete projects for government, major mining houses and the private sector.

Infrastructure employs over 1200 employees ranging from artisan to management level.

Esor Civils has been responsible for the construction of various, major roads throughout South Africa for both the Government and Private sectors. One of the first road building contracts completed by Patula in 1997, was in the North West Province, for the Mareetsane Local District Municipality, at the Kalgold Mine.  Approximately 3.5 km of road and associate works. 

Thereafter, followed more work for the mines, this time in Limpopo province, for the Swartwater Diamond Mine.  7 kms of access road had to be constructed.  In 1998 a heavy duty haul road was constructed for the Douglas Collieries in Witbank.

Dr. James Moroka Drive, a main road in Mafikeng, was constructed in 1998, followed closely by Sekame Road.  In 2001 an upgrading (extended dual carriage ways) was allotted to Patula, thereby proving the professionalism and workmanship of Patula in the North West Province.

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.
