The Project then went out to tender two years ago.

7 Franki was not successful. At the time its resources were tied up in two major projects in close proximity to the Total Office Tower, which meant factoring in 1 Franki changing the skyline of LuandaOver the years Franki has done some landmark geotechnical work, providing interesting, innovative and often brilliant solutions for a vast range of differing geological conditions. But few are more special than its recent successes in Luanda, Angola, where it has completed several projects on five-million-year-old relic beaches where the sea had receded and where building occurs at various levels on these ancient beach slopes.

8 Each position brings with it its own unique geological challenges and appropriate solutions. This story is about two of these current projectsthe costs of bringing in new resources and machines, resulting in Franki being knocked out on Project was awarded to a well-known European competitor in Angola. This company completed the installation of soldier piles, but its proposed founda-tion piling solution was not suited to the geotechnical conditions, and hence its contract was Franki was called in again, and successfully negotiated with the client and main contractor, Soares Da Costa whom Franki had met eight years previously when work first commenced on the Torres Atlantico Project , also in Luanda to redesign the foundation solution and expedite the works to recover the approximately two months lost time.

9 Franki, with its prior knowledge of the conditions through its original design input, opted for the piled solution outlined in its initial geotechnical support documentation. The Continuous Flight Auger (CFA) pile was the optimal solution for these conditions and with the equipment now available, we were able to successfully complete the pile installation and to contribute significantly to bringing the Project back on track, says Franki technical director Gavin adds that part of Franki s con-tract was to also complete the lateral sup-port that had been partially completed by the previous company.

10 Here it was neces-sary for us to redesign the anchor tie-back. 503 no x 650 mm diameter CFA grout piles with a working load capacity of 2 250 kN have been installed on the Tower block and parking area. 58 no Titan micropiles are currently being installed on the Utility block of the Project . 155 no, 52/26 Titan lateral support anchors have been installed for the lateral support on the soil comprised dense, fine and medium beach sand to depths in excess of 40 m, and the pile depth, an average of 16 m, was determined by the load capacity requirement and the overall settlement limitations required by the Tower Schultz, director of Franki frica Sucursal Angola, says that one of the challenges on this job was the partially constructed building on the site, dating from before the Angolan Civil War and ultimately abandoned with a basement and its piling structure intact.
