Upgrade of N3 between Paradise Valley, Mariannhill and Hammarsdale, Durban, S.AFRICA (2017-18)

South African Road Agency SOC Ltd (SANRAL)

Engineers Representative and Specialist Engineering Geologist– The project involved the widening and upgrade of the National Route 3 between Paradise Valley (Section 1, km 17.5) and Hammarsdale (Section 2, km 8.1). Geotechnical works comprised the investigation, and design of cut and fill retaining walls, soil and rock slopes, structure abutments, and pile foundations to several bridges.As the Engineers Representative on site, Brendon was responsible for all aspects of the geotechnical investigations and design including overseeing and managing the drilling contracts, checking and reviewing logging, laboratory testing, specialist in-situ testing, geophysical testing as well as the production of the factual geotechnical report.  He was also involved in the design and analysis of slopes, as well as cut and fill retaining walls.  He was responsible for developing the geotechnical model for the widening of the 75 m-high Mhlatuzana viaduct, which is characterised by a complex geology resulting in highly variable foundation conditions. Firm Fee: US$0.3million (2016).

Van Reenen’s Pass Feasibility Study, KwaZulu Natal, S.AFRICA (2017)

South African Road Agency SOC Ltd (SANRAL)

Specialist Engineering Geologist The project included the geotechnical investigation and evaluation of the feasibility for a potential alternative route for the N3 near Van Reenen.  The route includes very deep excavations, tunnels (drill-and-blast and cut-and-cover) and several large bridges and viaducts. Brendon, was responsible for the geotechnical investigation, including the supervision of drilling, undertaking the logging of core, assessment of material utilisation, rock mass characterisation, as well as the design and analysis of the slopes and tunnels along the route.  Fee: US$0.1Million (2017).

Gautrain Rapid Rail Phase 2 Network Extensions, SOUTH AFRICA (2016)

Gautrain Management Agency

Engineering Geologist – The project involved a desk study of engineering geological, geotechnical engineering and tunnelling conditions affecting some 150km of proposed network extensions for the Gautrain, as part of the phase 2 feasibility study. This included studies of undermining and a detailed dolomite risk assessment on the Naledi (Soweto) to Mamelodi Section.  

Brendon was responsible for leading a team of four engineering geologists who reviewed over 5000 dolomite reports and developed a dolomite risk hazard map for sections of the route over dolomite. Additionally he completed desk study reports and ground engineering risk assessments for various sections of the route. Fee: US$1.5Million.

Mtentu and Msikaba Bridges, Wild Coast, SOUTH AFRICA (2016)

Client: South African Road Agency Limited

Engineering Geologist Specialist– The project involved the identification and investigation of potential aggregate sources for the proposed Msikaba and Mtentu bridges, which will be South Africa’s two largest bridges, and form part of the proposed Wild Coast Highway which significantly improve access and  economic conditions for people living in the poorest part of South Africa.

Brendon was responsible for undertaking a detailed desk study of published sources with regards to the use of tillite as an aggregate source and critically reviewing the investigations undertaken during the feasibility stage of the project. This input formed the basis for the planning and further investigation of material sources. He was furthermore responsible for reviewing the borehole logs and assisting in the preparation of the final geotechnical report.

Moatize to Nacala Railway Expansion, MOZAMBIQUE/MALAWI (2011-12)

Client: Vale Moçambique Limitada / Aurecon

Project Engineering Geologist –The project included the geotechnical investigation for the detail design phase (FEL4) of the coal railway line between Moatize and the Port of Nacala, including investigations for cuttings, fills, bridges, and facilities along the centreline. Working  as part of a large team for this major project Brendon was responsible for aspects of the geotechnical investigations which including; supervision of on-site testing (SPT and Shelby-tube sampling of soil, as well as WPT in rock); borehole core logging; core sampling; inclined core orientation; StereoCore PhotoLog; intensive surface and structural mapping; test pit profiling; soil sampling; and the production of the factual geotechnical reports along the route.

Northern Aqueduct Pipeline Project, SOUTH AFRICA (2011)

Client: Knight Piésold / Naidu Consulting

Engineering Geologist –Geotechnical investigation for a large diameter feeder pipeline from the western aqueduct connecting the reservoirs of Durban.  Brendon worked as part of a large team, with project specific responsibilities including: planning of the site investigation for portions of the pipeline route; soil profiling of excavated trial pits; supervision of on-site testing (DPL), soil sampling; materials classification from laboratory results; and preparation of geotechnical reports including the recommendations of materials usage and excavation of materials along the pipeline
