Geotechnical Engineering Projects

Grounded Geotechnical Engineers Where You Need Them

NAL has offices in New Zealand and Malaysia from where we service clients’ geotechnical engineering projects in New Zealand, Malaysia, Fiji, Samoa, Tonga, America Samoa, Bahrain, and Cambodia. Our consulting engineers work with clients on civil, structural and geotechnical engineering projects for residential, commercial, industrial and public works.

Our experienced team of geotechnical engineers gets called upon to plan, design, organise and oversee earthworks for small house additions to large subdivisions. Our experience with geotech reports, landslip assessments, retaining wall design and on-site wastewater disposal assessments helps developers, councils and private landowners keep their projects on scope and on solid foundations.

Taputimu Shoreline Protection,
American Samoa

Scope

Geotechnical

Description

NAL Civil & Structural Engineers were engaged by McConnell Dowell (American Samoa) Limited to provide geotechnical engineering services for Taputimu Shoreline Protection project in American Samoa. The scope of work consisted of carrying out a visual geotechnical assessment of a 5.5-metre-high excavation during the construction of the seawall and concrete crib structure.

NAL’s responsibilities included providing professional geotechnical advice to the contractor during the excavation near the ocean front on American Samoa. The excavation was approximately 5.5m high; a steep excavation of 80 degrees of Leone Volcanic formation. Based on the geotechnical assessment and assumed parameters, NAL was able to recommend the angle of friction of the overburden soil to calculate the failure of the excavated cut face.

Scope

Geotechnical

Description

NAL Civil & Structural Engineers was engaged by Auckland Council to conduct a site investigation and provide a geotechnical report for the proposed solution to the slip at the true right of the Marama Stream, Huia. The scope of work was to carry out the geotechnical slope analysis for which hand auguring and dynamic (scala) penetrometer were performed. 

To remedy the slip, NAL proposed constructing gabion baskets in accordance with the current construction code and Auckland Council requirements. From our analysis, our geotechnical engineers we able to assess the ultimate bearing capacity of the soil and provide a suitable depth for the footings and gabion baskets.

Scope

Geotechnical

Description

Our scope of work included the analysis and preparation of a geotechnical report on the slope stability on a vacant piece of land on which a new two-storey residential building was the purposed. The development encompassed constructing a retaining structure to protect the ground stability for the proposed building.

NAL’s responsibilities were to address the geotechnical soil parameters through a site investigation by means of hand auguring and dynamic (scala) penetrations. Our geotechnical engineers were to evaluate any future slope failure and to propose the bearing capacity for the relevant footings in accordance with the current construction code and Auckland Council requirements.

Namata Village Crossing,
Fiji Islands

Scope

Geotechnical and Structural

Description

NAL Civil & Structural Engineers was engaged to provide geotechnical and structural engineering services for the two new culvert crossings (8.0m and 19.5m) at Namata Village, approximately 3.5km North-East of Nausori town in the province of Tailevu, Fiji Islands.

NAL responsibilities involved carrying out a shallow geotechnical site investigation in order to identify the geotechnical design parameters for the new foundations. The site investigation was carried out by hand auguring and dynamic (scala) penetrations. Our geotechnical engineers then proposed an ultimate bearing capacity based on current construction codes and Fiji Roads Authority (FRA) guidance documents.

The design of the crossing involved structural loading analysis of precast walls and deck structure based on current New Zealand loading code requirements and those specified in the FRA. The design life of the culvert structure is 100 years, as per FRA’s stipulations.

Sopu,
Tonga

Scope

Geotechnical

Description

NAL Civil & Structural Engineers was engaged to provide geotechnical services for a new singe-storey meeting house, accessway, car parking and playcourt area at Sopu, Tonga. 

During the site investigation, a digger was used to dig four test pits to a maximum depth of 5.0m below existing ground level. Up to 16 hand auger holes and 16 scala penetrometer tests were also carried out. NAL’s responsibilities were to identify the geotechnical design parameters for pavement and foundation structures for the meeting house, accessway, car park and playcourt area.
