The Rewa River Water Supply Scheme (RRWSS) addresses the current shortfall in bulk water supply and water treatment during peak demand periods and aims to improve water supply reliability across Suva-Nausori. Furthermore, the project provides additional water supply for new areas to facilitate growth in the system and enhance the overall scheme's security. The key components of the scheme include new river intake works, a raw water pump station, a water treatment plant with a capacity of 40MLD designed to accommodate a future load of 100 MLD, a 900mm diameter, 7.5km steel rising main leading to a new 10ML reservoir, and a 900mm diameter steel, 17.8km gravity pipeline connecting to the current Suva-Nausori water supply network, along with 7 steel pipe bridges. SMEC was engaged by WAF to provide comprehensive contract management and construction supervision support for the effective delivery of the proposed RRWSS.

In 2016, the Government of Fiji received a loan from the Asian Development Bank (ADB) to prepare for the Urban Water Supply and Wastewater Management Investment Programme. This initiative aims to assist the Government, specifically through the Water Authority of Fiji (WAF), in a significant upgrade of water supply and wastewater infrastructure and services within the Greater Suva Area (GSA). The goal is to enhance WAF's management capabilities and service delivery. The proposed investment programme's impact is to ensure the sustainability of future growth in the GSA while also improving public health. This will lead to better access to sustainable water supply and sewerage services. SMEC was engaged by WAF to provide support for the Investment Programme Management Unit, aiding in project preparation and implementation within the programme. 

Located in Suva, the US$90 million ADB/World Bank-funded Road upgrade project aims to improve the main urban collector roads and some arterial roads in Suva city. As part of SARUP 2, the FRA is proposing to rehabilitate and upgrade 17 sections of existing sealed roads comprising of approximately 16.8 km of roads in the Greater Suva Area. For most of these roads, the works will involve pavement rehabilitation and resurfacing, widening narrow sections (within the existing road reserve) and improvement of drainage, kerb and channel and pedestrian facilities. SMEC acts as the ‘Engineer-to-Contract’ for the Project. The original project was cancelled and reverted to a traditional Design and Construction project. SMEC is responsible for the design review, contract documentation, assistance to the client with tender evaluations.

SMEC has been appointed by the Fiji Roads Authority (FRA) as the Engineer to the Contract, responsible for designing and managing the construction supervision of approximately 55km of Kings Road. This road constitutes a significant portion of the road network encircling the island of Viti Levu, the largest island in Fiji and home to over 600,000 people, accounting for 70% of the population. The scope of work encompasses various tasks, including conducting a topographical survey, sampling and testing materials, creating 3D models to aid in the design process, reviewing and optimizing the FRA's design, and preparing construction drawings for the contractor's use in implementation. The road upgrading project involves several aspects, such as providing shoulders and verges to enhance road alignment, constructing roadside drains and culverts, installing road furniture, and completing ancillary works to improve the existing narrow carriageway.
