A 15kWp off-grid, ground-mount solar PV system was installed on a wooden sub-structure on Dassen Island.
The installation stores energy into a 48kWh Li-ion battery set and is integrated with a generator set as back-up.
The island is located 9km off Yzerforntein, Western Cape.
Installation of a 367 kWp grid-tied rooftop Solar PV system, consisting of 1129 PV panels and 15 x SMA inverters
Phase I of the construction of the new Hani Park Primary School has been successfully completed with anticipated completion of Phase II end of May 2018.
The school consists of four classroom blocks totalling 27 classrooms, as well as additional structures for two computer laboratories, administration building, hall and gate house. The expected number of learners for Hani Park Primary School is to be in the vicinity of 1 080.
BVi Consulting Engineers Western Cape (Pty) Ltd was appointed by the Western Cape Government, Department of Transport and Public Works for the implementation of various rooftop Solar PV systems on several buildings identified in the Cape Town Metropolitan area, which are owned and/or operated by the Western Cape Government. BVi’s involvement entails the conceptual design, tender documentation, design approval, construction monitoring and contract administration.
These systems are grid-tied and reduce the purchase of grid electricity from the City of Cape Town. The savings from avoided electricity purchases are providing the financial returns necessary to justify additional capital and operating costs of the systems.
Construction on new Police Station Buildings and Staff Quarters
Refurbishment of Existing Buildings
Design and site supervision of the construction of roads, stormwater, footpaths, pipe bridges, sewer pipelines / manholes and retaining walls.
Design, construction supervision and quality control of a new National English Literary Museum, including exhibition venues, archives, libraries, auditorium, theatre, offices, etc. The design is based on 5 Star GBSA Green rating specifications. The engineering works include a civil infrastructure portal and RC framed buildings, soil nailing and tanking.
Replacing of failed civil infrastructure to the existing complex and re-construction of failed structural elements to the buildings.
Design of mechanical ventilation system to extract fumes from the extruction plant. The ventilation system was to comply with health and safety requirement and city of cape town health by-laws. The ventilation system was to provide the workers with a conducive and safe working environment.
BVi was responsible for the electrical and infrastructure design and contract management for the repair and renovations of various low-rise buildings.
The following services were involved:
Lighting, small power, distribution boards, lightning protection, earthing and bonding, electrical infrastructure, miniature substations, emergency generator sets, 11kV main panel, 11kV overhead line, Area lighting, HVAC, Fresh air. Wet services, kitchen equipment, extraction canopy.
The new 400-bed state hospital with theatres, wards, laundry, kitchen, mortuary, ambulance EMS and married quarters. The project was extended with a new 42- bed TB hospital with its own laundry and kitchen.
The Forensic Science Building is regarded as one of the most complex and technically sophisticated buildings in South Africa. Various systems were installed under the electrical and mechanical trades to incorporate the clients’ requirements. Due to the usage of the facility, high security measures were implemented inside and outside the building.
On the electrical and security side, the building is equipped with the following equipment:
Technical Support to the In-house Construction Unit of the Department of Roads and Public Works
New Jubilee Primary School
Graaff-Reinet Water Augmentation Scheme for Drought Relief
The building is 8000m2 and cost +/- R105,000,000.00 it is full of architectural features which also makes it a building which is quite expensive for its size. The architectural features stand out and provided engineering challenges and therefore it is definitely regarded as a landmark:
Low-cost housing scheme (600 units)
Helenvale Thusong Service and Community Centre
This project comprised the complete upgrade of a rather dilapidated heritage building. It consisted of a complete makeover of the building including all the engineering disciplines.
The primary objective of the first phase was to repair the failing plaster/grano façade of the building. This became a threat to pedestrian and vehicle traffic. This phase consisted of the removal and subsequent major concrete rehabilitation to an area of 28 400m². Use was made of external scaffolding supported on a reinforced concrete canopy over the sidewalk. This structure served as a scaffold support as well as safety for the pedestrians not to interrupt the building functionality. It is to be noted that the scaffolding was to the full 26 storeys – the highest used in the Southern Hemisphere.
The second phase was for additional facilities, basement parking, upgrading of the present Keerom Street walk-through to a functional and friendly pedestrian area with a restaurant and other public facilities.
This forensic science building is regarded as one of the most complex and technically sophisticated buildings in Southern Africa. The building was planned in a five “finger” pattern for the five different departments. It is a four-storey building with basement parking adding up to 26 000m² floor area.
This project consisted of two blocks seven storeys high plus three levels of underground basement parking.

124 Parking Bays, Fan Rooms, Water Tank Room
The project is about conducting feasibility studies on river structures and investigation on the Skoenmakers River which has been utilised as a conveyance system and spillway to Darlington Dam since 1981. The feasibility studies are necessitated by deterioration of the river channel over the years which have resulted in the erosion of the river embankments, creation of an island in the river bed, loss of vegetation, erosion of some bridge-supporting embankments and transportation of vegetation and silt downstream. Investigate the impact of water releases down the river bridge and compilation of a river rehabilitation strategy to improve access across the river and to halt further degradation of the river.
The aim of the assignment is to assist the National Water Resources Infrastructure (NWRI) in understanding the impact of water release down the Skoenmakers River in an effort to have intervention measures put in place to upgrade the river bridge structures and prevent further deterioration of the river embankments and bed to minimise the loss of human lives, livestock and wildlife in the area.
