Preface to Civil Engineering Focus on Geotechnical Engineering

WHILE MANY OF its opponents are at sea in the case of implementing profitable marine options, Franki Africa,

a part of the JSE-listed Esorfranki group, has its ft firmly on the bottom, efficiently delivering options on this difficult setting.

Among the firm’s most profitable contracts within the final decade are a sworn statement to this.

These initiatives embrace the set up of foundations for a shipbuildingand restore yard, a quay wall and a dry dock within the Port of St Louis in Mauritius;

the Frois Des Mascareignes job, additionally in Mauritius, which concerned main growth to the prevailing berthing amenities;

within the Seychelles the Tuna Quay the place the marina was prolonged greater than 200 m and by greater than 1800 m2.

And the demanding R213 million Transnet-designed Berth 208 within the Port of Richards Bay.

So, when it got here to the piling and basis work for the extension into the ocean of Durban’s Sandile Thusi (Argyle) Street stormwater outflow pipe (referred to as the ‘shotgun pier’ due to its double-barrelled construction),

it was no shock that Franki was requested by all of the tenderering most important contractors to cite because the specialist subcontractor for this work.

Finally the contract was awarded to Esor Africa, Franki’s stable- mate within the Esorfranki group. Franki did the short-term works and iling 20 years in the past,

when the unique out- move was constructed. Within the 20 years for the reason that ‘shotgun’ was first constructed, there demanding R213 million Transnet- designed Berth 208 within the Port of Richards Bay.

Within the 20 years for the reason that ‘shotgun’ was first constructed, there have been vital sand deposits on this stretch of beachfront, successfully leaving the outlet in the midst of the seashore.

This has necessitated its extension again into the ocean, to forestall silting-up and additional flooding again within the stormwater system.

The fundamental scope of works was to design and assemble each a short lived jetty and co fferdam with a 5 m excessive safety wall for the development of the prolonged concrete ‘shotgun’ outfall.

These two important elements not solely permit for the development of the everlasting construction.

But in addition guarantee entry and a secure working setting for the principle contractor. “Whereas on the face of it the duty does not appear that difficult,

working within the ocean is clearly by no means straightforward and a number of other components complicate the manufacturing course of and make accuracies very chal lenging.

” says Marcel Hofmann, Franki’s Durban divisional supervisor The short-term jetty, a key aspect on this contract, is 70 m lengthy and wanted to be sufficiently sturdy to help two tracked 80 t crawler cranes.

This was achieved by putting in 28 metal tube piles in pairs for the legs of every jetty part.

The method requires a information body, which assists with the positioning of the piles, after which, with the correct tools,

they’re put in to the required depih,” says Ilofmann, aling thai th constrinitial safety from the ocean and entry to ihe jeiy throughont the challenge as achieved utilizing sheet piles. uction of an abutment to offer
