Rakhine, Myanmar - Winter Crop Project

Myanmar 4x4
Assistance with an irrigation development programme on behalf of MFAT, where key issues facing crop farmers include challenging climate effects on local agriculture and consequent economy. The project included the goal of constructing up to five gravity irrigation schemes and eight smaller pump schemes. Site surveys of the proposed dam sites were undertaken, the feasibility of which was assessed by back-solving the required demand and comparing it with the cost of the five storage opportunities. This eliminated two sites. Previously constructed schemes were often abandoned or dug up and sold for parts when a failure occurred that the farmers were unable to fix. This highlighted that engineering input would need to diverge from normal practice to accommodate the goals of development work. The long-term success of these irrigation schemes relies on local farming communities operating and maintaining the infrastructure over its lifespan without dependence on western input, therefore, our scope shifted from directly designing dams and distribution, to assisting a local engineer to deliver a solution and install local expertise to ensure the project’s future. Construction has yet to commence.


Malau Wharf, Labasa, Fiji

MalauWharf 400
A ship berthing collision severely damaged a raw sugar loading wharf in northern Fiji. A geotechnical investigation from a barge was undertaken in 11m of water. Replacement driven steel tube piles were designed using GRLWEAP computer analysis for inclined pile driving to remediate the facility.

Mamanuca Archipelago Resort, Fiji, Slip Remediation

Mamanuca 400
Heavy rain in January 2009 caused a large landslip at a luxury island resort in Fiji. RILEY was commissioned to investigate the incident and provide recommendations for stabilisation of the affected area, and practical remedial recommendations to improve overall stability of the steep slope backing on to the resort.
