Brown Engineering Group manufactures Gwebi River Bridge steel girders

Although the Brown Engineering Group has a wealth of experience in many diverse areas of the engineering, construction and manufacturing industries the Gwebi River Bridge is their first vehicle road bridge.

The bridge was commissioned by the Ministry of Transport and Infrastructure Development as part of the dualisation of the Old Mazoe Road from the Westgate roundabout to the Mvurwi turn off.

It’s part of the government’s drive to develop infrastructure in line with the policy framework for Vision 2030.

It will improve travel time, increase motorists’ safety as well as providing easier access to the New Parliament. The bridge was designed by ZICAD

Engineering Consultants, leaders in the field of Mechanical, Electrical and Project Management Services (MEP), with the Ministry of Transport and Infrastructural Development as the client.

The design follows the specifications set out by the Ministry of Transport and Infrastructure Development Part JD which deals with bridge construction.

Brown Engineering Group was selected to supply the steel works. Exodus and Company are constructing this section of the new dual carriageway and are also doing the civil works for the bridge.

The bridge has a 20-meter clear span above the river. The steel girders, which were custom manufactured and fitted by

Brown Engineering Group, sit on top of the massive concrete wall type abutments on either side of the river built by Exodus and Company.

The steel girders are fixed to the abutments by elastomeric bridge bearing pads of steel and rubber which let the steel shift slightly to accommodate expansion and contraction.

There is a 40mm gap at either end of the girders to allow for movement.

Brown Engineering custom manufactured the girders in three sections welded together to create a kind of I-beam 1.3 meters high.

The extra-long welds, using the sub-arc welding technique, were particularly difficult and demanding to achieve. Each girder is made up of two sections – one 8 meters long and one 12 meters long – to make up the 20-meter span.

The welding was inspected and approved by two independent engineering companies, ZICAD and Probitas Engineers to verify and approve their structural integrity.

Between the steel girders Exodus and Company will install pre-cast concrete panels fixed to the shear lugs which Brown Engineering Group manufactured on their girders.

The lugs function to fix the concrete panels to the steel. On top of the precast panels will be a concrete deck with a final asphalt layer on top.

Each of the steel girders manufactured and fitted by Brown Engineering Group weighs just over 17 tonnes.

They were manufactured in two parts, comprised of 12 meters and 8 meters, to form the required 20-meter span, as well as for ease of transportation and handling.

The longer section weighs 10 tonnes and the shorter section 7 and a half tonnes. They were loaded onto Brown Engineering Group’s truck using a 20 tonne crane and a 160 tonne crane on site to lift the girders in to position.

Because of the enormous weight involved the girders were transported one at a time. Once on site they were assembled with 20mm splice plates and M30 bolts with a total of 106 bolts on each girder.

Brown Engineering Group purchased a special electronic Newton-Meter Torque wrench to guarantee the bolts were correctly tightened to the highest specifications.

The girders were painted with corrosion resistant epoxy to ensure an extended life span of at least 100 years. The design also includes future proofing the structure to accommodate climate change issues like flooding or extreme weather fluctuations.

The procurement and fabrication took one month and the installation took a week. Once completed the bridge will have concrete stanchion parapets and steel railings for safety, supplied in conjunction by Brown Engineering Group and Exodus and Company.

There will also be a single lane for pedestrian access.

Although this will be Brown Engineering Group’s first vehicle road bridge they have provided the pedestrian bridge at Eastgate Mall.

They are currently supplying the steel work for many warehouses across the country, and the continuing development of a range of upmarket shopping malls.

They are also involved with the construction of the exciting new waste-to-energy project undertaken by Geo Pomona Waste Management, so their portfolio is impressive and diverse.

Harare's Infrastructure Renaissance: A Symphony of Engineering Excellence

Harare's urban landscape is undergoing a dramatic transformation, with the Gwebi River Bridge standing as a prime example of the city's infrastructure renaissance.

This monumental project is a testament to the powerful synergy between government vision and private sector expertise.

At the heart of this transformation is Exodus and Company Pvt Ltd, whose role in dualizing and rehabilitating key road sections has significantly improved traffic flow and overall road safety.

The construction of the Gwebi River Bridge, a cornerstone of this broader initiative, further solidifies Exodus's contribution to Harare's progress.

Beyond road improvements, the project extended to beautifying and upgrading Old Mazowe Road, a vital thoroughfare connecting key points like Westgate, Mt. Hampden, Loop Road, and the new Parliament Building. The Gwebi River Bridge itself is a marvel of engineering.

ZICAD Consulting Engineers provided the visionary design, ensuring the structure's functionality, safety, and aesthetic appeal.Their meticulous attention to detail and commitment to sustainable development are evident in the bridge's harmonious integration with the surrounding environment.

B&S played a pivotal role in bringing the design to life through their construction expertise. Their focus on reinforcement and decking was crucial in creating a bridge that is both sturdy and durable.

By meticulously reinforcing the bridge's structure and crafting a safe and resilient surface, B&S ensured the bridge's longevity and efficiency.

The project also benefited from the expertise of Brown Engineering and National Cranes & Equipment in erecting the bridge's steel structure, as well as the contributions of Fourways Concrete and Acsend Concrete for concrete supply.

Additional support from companies like Mike Appel, Hitbay Sanitation, CBF, and Adelcraft provided essential specialized services for the project's success.

German Formwork & Sca olding Specialist

The Gwebi River Bridge stands as a symbol of Harare's progress and a testament to the power of public-private partnerships.

It is a collaborative effort that showcases the combined expertise of engineers, designers, and construction experts working together to create a landmark infrastructure that will serve the city for generations to come.

This successful project underscores the immense potential of public-private partnerships in driving infrastructure development. By combining government vision with private sector efficiency,

Zimbabwe has demonstrated its ability to deliver transformative projects that will benefit the nation for years to come.

WHY is GOOD QUALITY STEEL IMPORTANT WHEN LASER CUTTING?

Good quality steel plays a crucial role in laser cutting for several reasons:

Consistent Cutting Performance: 1.

High-quality steel ensures consistent material properties, such as hardness and composition Consistency leads to predictable cutting results, minimizing variations in cut quality and reducing the risk of defects.

Reduced Heat-Affected Zone (HAZ): 2.

When laser cutting, the heat generated by the laser beam affects the surrounding material.

Good quality steel has uniform composition, which results in a smaller HAZ.

A smaller HAZ means less distortion, better edge quality, and improved precision.

Minimized Residue and Contamination: 3

Inferior steel may contain impurities, which can lead to slag or dross formation during laser cutting

High-quality steel produces cleaner cuts with minimal residue reducing post-processing efforts.

and optics to extreme conditions

Using good quality steel reduces wear and these components, prolonging their lifespa

5. Cost Efficiency:

While high-quality steel may have a higher cost it pays off in the long run

New Warehouse for Paramount Garments -A Practical Marvel by RadX Construction

Throughout Southern Africa, RadX Construction prides itself in delivering quality construction projects for clients across all sectors (including Industrial and Commercial, Hospitality and Residential, Mining and Oil & Gas, Construction Camps and Infrastructure). RadX’s expertise includes civil and building construction, engineering design, project management, quantity surveying, architecture and design-build solutions. The company’s track record speaks for itself and has resulted in some of the world’s largest blue-chip companies placing their trust in the company.

RadX Construction has reaffirmed its place in the construction space with the swift and successful completion of a warehouse project in Msasa. The warehouse is designed to house three shops, with the main anchor being Paramount Garments.

Starting on January 2, 2024 and reaching full practical completion by May 31, 2024, this project is a peak exhibition of RadX's exceptional capabilities. Throughout the project, RadX Construction maintained a close working relationship with the client, Paramount Garments.

Regular site visits and constant communication ensured that any changes or decisions were handled promptly and collaboratively. Decisions were easy, and the client was very hands-on," notes project manager Daniel Machibaya. "We were part of the design stage and any changes were discussed openly.

This team effort made the project seamless and enjoyable. "

The primary objective of this project was to construct a state-of-the-art warehouse for Paramount Garments within a budget of $1.2 million USD.

It features a flat, sloped roof and is situated on a property spanning 4113 square metres with the building footprint covering 1777 square metres and an additional 2177 square metres dedicated to paved areas.

The scope of work was extensive, including excavations, earthworks, formwork, reinforcement, concrete works, brickwork, plastering, carpentry, joinery, ironmongery and painting.

All of this was handled painstakingly from the installation of aluminium doors and roller-shutter doors up to the intricate brick dressing and suspended ceilings. The project faced several challenges, particularly the timing of the start date during the annual construction holiday.

Machibaya remarks, "We started the project on January 2, cutting short our annual construction holiday to ensure that all stub columns were in place by the time the steel structure was ready for erection.

We also had to manually pour about 85m³ of concrete on-site since the main pre-mix concrete suppliers were closed."

The busy location on Mutare Road also posed logistical challenges but RadX seems to have turned this into an advantage.

"We wanted the project to be a practical marvel for passers-by, which would help in marketing our company and what it stands for – BUILDING TRUST," Machibaya adds.

Despite the complexities of the project, RadX Construction successfully managed the budget, making only minor adjustments. Machibaya explains, "There were some minor additions at the deck on shop one and at the rainwater sump, but nothing that significantly altered the scope or budget.

The client was very hands-on, and we maintained constant communication to ensure any changes were seamlessly integrated."

One of the standout features of the warehouse is its face-bricked exterior and interior, giving a different texture and a rustic industrial feel.

Coupled with the structural steel, it ties in nicely to create a modern yet industrial look. RadX Construction has also equipped this warehouse with impressive sustainability features.

Fence Smart, Live Safe

The roof hosts a substantial solar farm with about 72 solar panels, seeing to it that the warehouse predominantly runs on solar energy, with the electrical grid serving as a backup only when necessary.

An intricate rainwater harvesting system complements this green energy initiative. Rainwater collected from the 1777-square-metre roof is directed into a sump, which then pumps it into a 228,000-litre water ZimDam reservoir.

Notably, three-quarters of this reservoir’s capacity is dedicated solely to fire safety, a precautionary measure following a previous fire incident in one of Paramount's warehouses in 2023. Additionally, a separate 5,000-litre tank is used for further rainwater harvesting.

RadX Construction's success on this project is also thanks to the strong partnerships they maintain with various suppliers and contractors.

The architectural vision was drawn by Mark Sanderson of Draftworx Design while Brown Engineering handled the roofing.

Pomona Bricks supplied the pavers, Tiger Bricks provided the bricks and long-time collaborator Gillfun Steel supplied the reinforcement steel.

Derick Kambarami of InfraDesign and David Gutu of David Gutu and Associates formed the consulting team.
