Editor's Comment

Within a short amount of time, the Russia-Ukraine war has created the largest humanitarian crisis that Europe has seen in decades. An ongoing tragedy growing larger in scale, the total implications of this conflict have yet to be fully realized The war in Ukraine has put added strain on a construction indsutry already reeling from the impact of the pandemic that caused supply chain constraints and shortages in an industry that is characterised by tight deadlines and slim profit margins for constractors.

Managed IT Services Most companies today rely on technology to run their operations.

We take a look at how managed IT services can benefit a construction firm.

This new global crisis has already seen sky rocketing fuel prices that have accelerated inflationary trends around the world including Africa.

32

The fact that Ukraine is the 5th largest exporter of iron ore will also put constraints on steel supplies further exacerbating the industry's woes.

Concrete mixers We take a look at the different types of concrete mixers. Each one is appropriate for specific situations. Get the right one for your needs.

Construction projects can be expected to slow down as economies feel the strain caused by inflationary pressures principally caused by high fuel prices that tend to affect all sectors of the economy.

CORPORATE NEWS

Grupel supplies project for support of the EXEO Office Campus, in Lisbon Grupel has produced and supplied a generator set to support a business center in Lisbon (Portugal), the EXEO Office Campus.

The project is composed by a soundproof generator of 825KVA, with an alternator of Grupel’s brand and equipped with PMG, which allows a quick balance of the group's voltage, in case of oscillation of the facility's load.

Bamburi Cement Launches Tile Adhesive Leading cement manufacturer Bamburi Cement has entered the specialized mortar market with its launch of Bamburi TectorCeram SETI 300, a ready-to-use tile adhesive.

Designed for placement of porous tiles including ceramic, terracotta, earthenware and natural stone tiles, Bamburi TectorCeram SETI 300 is a cementitious mortar product produced from carefully sourced raw materials, including chemical admixtures, cement and sand.

“We are delighted to tap into the growing demand for specialty mortar products such as tile adhesives”, said Seddiq Hassani, Bamburi Cement Managing Director. “As a champion for innovation in construction, Bamburi Cement is well-positioned to develop and present yet another construction solution to resolve challenges in the tiling sector.”

It is made to operate in standby mode, taking on its role when there is a failure of the regular electrical grid and whenever the photovoltaic panels on the site, which work in parallel with the grid for self-consumption, are disconnected.

Grupel is a Portuguese company, founded in 1976, that produces and sells portable and stationary power generators up to 3500kVA, as well as portable lighting towers.

Equipped with components from internationally renowned brands besides our own brand, Grupel products are distinguished by their reliability and resistance.

They have the largest production unit of power generators, in Portugal, located in Aveiro - which allows them a great flexibility to produce standard power generators and complex and customized special projects.

The new tile adhesive is suitable for interior tiling solutions such as floors and walls and only requires the addition of water on site. Its advanced formulation and creamy workability significantly increases the bonding strength and speeds up construction work.

The product is already available in hardware shops countrywide and will also be available elsewhere in the region through Bamburi’s extensive distribution network.

Mecalac Launches Trio of new Swing Loaders Mecalac, a global leader in the design, manufacture and distribution of compact equipment for urban construction sites has launched the all-new AS750, AS850 and AS1000 models join the existing AS600, AS900tele, AS1600 and AS210.

The AS750 is the big sister of the Mecalac AS600 Swing Loader, boasting a larger width and an increased wheelbase (1,870 mm) for even greater stability. The engine power has been increased to 45kW / 61hp to provide more lifting and loading capacity, while P-bucket kinematics offer excellent precision during handling operations, particularly with the pallet lift or load hook. The spacious cab, with two doors, provides the operator 4

torque engine (375 Nm), while the option of a high-flow hydraulic line offers up to 120 l/min – perfect for driving hydraulic attachments.

With the AS850, productivity is key. Featuring all the advantages of Mecalac's swing machines, including a rigid chassis and four-wheel steering, the AS850 is also available in a 40 km/h option for faster transfers. In addition, a brand new arm and "Z" bucket kinematics offer the best compromise between digging power and precision.

A more powerful version of the AS850, the Mecalac AS1000 swing loader excels on any job site thanks to its impressive efficiency and unmatched speed of execution. The AS1000 offers maximum performance with a 4-cylinder 55.4 kW / 75 hp high-

COVER STORY

Nigeria-Morocco Gas Pipeline Project

T

he Nigeria-Morocco Gas Pipeline ("NMGP") is a proposed regional onshore and offshore gas pipeline that is intended to deliver natural gas resources from Nigeria to 13 countries in the West and North Africa as a continuation of the existing West Africa Gas Pipeline ("WAGP") between Nigeria, Benin, Togo, and Ghana.

Starting from Nigeria, the 5,660 kilometres long NMGP will pass through Benin, Togo, Ghana, Cote d’Ivoire, Liberia, Sierra Leone, Guinea, Guinea6

Bissau, Gambia, Senegal, and Mauritania, to end at Tangiers, a Moroccan port on the Strait of Gibraltar, with a possible extension to Europe through Spain.

The Nigeria-Morocco Gas Pipeline Project is estimated to cost US$ 25bn and it will be completed in stages over 25 years.

CR | March/April 2022

www.constructionreviewonline.com

COVER STORY

The project falls in line with the “Decade of Gas Master Plan” that Nigeria’s President Muhammadu Buhari launched in 2020. The master plan seeks to bolster Nigeria’s gas production and gas exports.

On the Moroccan side, this landmark project is part of the South-South cooperation upheld by King Mohammed VI. It is expected to create a competitive regional power market and benefit all West African people, countries, and their economies.

and in the same month, the two countries contracted with Penspen Engineering company to conduct the first phase of frontend engineering & design. FEED is the basic engineering which comes after the conceptual design or feasibility study Phase 1 scope of the Front End Engineering and Design (FEED) of the Nigeria Morocco Gas Pipeline (NMGP) was initially expected

to be completed in 2019 with phase 2 commencing in March 2020 front-end engineering and design had entered the second phase. However it is only recently that it was announced that WorleyParsons Limited, an Australian engineering company which provides project delivery and consulting services will carry out the second phase of the Islamic Development Bank (IDB) co-funded NMGP (Nigeria-Morocco

In August 2017 the NNPC and ONHYM had begun a feasibility study for the pipeline.

The study was completed in January 2019,

Gas Pipeline) project's Front End Engineering Study (FEED).

Worley's offshore engineering consultant subsidiary, Intecsea, situated in The Hague, Netherlands, will be in charge of the entire FEED services which the development of a project implementation framework as well as engineering survey monitoring.

As regards funding the Islamic Development Bank (IsDB) agreed to fund 50% of the Front-End Engineering Design (FEED) Study for the Nigeria-Morocco Gas Pipeline project. The multilateral development finance institution focused on Islamic finance will support the Moroccan contribution and participate in the financing of the project with US$ 15.4M under the “Service Ijara” operation.

For Nigeria, the IsDB will contribute US$ 29.7M to the FEED study which aims at preparing the required studies for the gas pipeline and help take the final investment decision by 2023 for the infrastructure project.

The IsDB funding will help carry out the environment & social impact study in order to ensure the project's compliance with all local and international environmental and social regulations and standards. It will also finance land acquisition studies for agreeing with all countries to be crossed by the pipeline to ensure smooth implementation of the works at a later stage.

OPEC Fund for International Development (OFID) is also reportedly set to contribute US$ 14.3M to fund the implementation of the second phase of the NMGP (Nigeria-Morocco Gas Pipeline) project's Front End Engineering Study (FEED).

This is after the intergovernmental development finance institution established back in 1976 by the Member States of the Organization of the Petroleum Exporting Countries, signed a financing agreement with Morocco.

With this agreement, OPEC Fund strengthens its financial cooperation links with Morocco and contributes to the Kingdom's economic and social dynamics by supporting the NMGP (Nigeria-Morocco Gas Pipeline) project, which is an example of South-South collaboration.

The Nigeria-Morocco gas pipeline is expected to improve access to energy across the West Africa region.

This will help address one of the region's most significant barriers to development, which is the lack of affordable energy, and consequently facilitate the expansion of sectors ranging from industry to food processing and fertilizers, and improve the competitiveness of exports amongst the African countries.

In addition, the project will strengthen energy exports to Europe.

PROJECT

eThekwini Gears Up for the Durban Eye Project

T

he R450 million Durban Eye project has been defended by Ethekwini Municipality, which claims it would be part of the municipality's economic infrastructure, attracting visitors, stimulating economic growth, and creating employment. During the week of the city's Travel Indaba, it was revealed that a multimillion-rand project would be erected in Durban. The city already boasts a number of tourist attractions, including uShaka Marine World, which is owned by the city.

Residents in Durban have criticised the proposal since it was announced, calling it a vanity project. The Durban Eye project, on the other hand, is a private venture, with the municipality just donating land for the project's construction. It entails constructing and installing a massive Ferris wheel on Vetch's Beach in the Point Waterfront zone, which will run along the northern breakwaters.

Development of the Durban Eye Project The R450 million Durban Eye developer has been chosen, and construction is set to begin in July. Once finished, this project will pro-

vide tourists with a breathtaking 360-degree panoramic perspective of the city. Msawakhe Mayisela, a municipality spokeswoman, said that this was a city initiative in terms of making the site accessible to the now pre-qualified bidder, who will invest in the facility's design, development, construction, operation, and management at no cost to the municipality. According to the city, the northern breakwater was chosen to be the most suitable and appealing backdrop for the proposed investment following months of site investigation and appraisal.

The Durban Eye project, according to Mayisela, would produce cash for the city through rents, with annual inflation-linked escalations over the projected 30-year term, after which the municipality would acquire the asset and any building modifications.

Mayisela said the city had received two unsolicited inquiries, one from an overseas business and the other from a local consortium with foreign partners, about the leasing of council-owned land obtained between 2018 and 2020.

near the Expressway’s entry/exit lanes features the following spaces: showroom/ retail (ground floor); food and beverage/ restaurant (second floor); Grade A offices (third to fourteenth) and conferencing facility (fourteenth). The multiple entry, exit points from the tower significantly cuts down travel time to Mlolongo, Athi River as well as Westlands and Limuru Road.

Purple Tower’s design has achieved EDGE sustainability requirements, a benchmark initiated by the IFC (International Finance Corporation), the private sector lending wing of the World Bank, to encourage the design and construction of sustainable, resource-efficient buildings in emerging markets. For a building to receive EDGE certification, its design must incorporate measures that enable it to achieve threshold energy savings, water savings and savings in energy of embodied materials.

Said Jiten Kerai, General Manager of Purple Dot International, “Purple Tower, presents a timely and strategic proposition for both local and regional investors in the Kenyan property market. With its innovative building design, EDGE Certification and locational advantages, the mixed-use development truly embodies our core business model with respect to socially responsible investing, giving discerning investors an opportunity to diversify their investment portfolio with a property that delivers higher ROI (Return on Investment) over time. “ Together with our partners, we have come up with flexible, adaptable office spaces supported by financing options that enable buyers who come on board now to earn value appreciation that is comparatively higher than if they invested the same amount in investments of a similar tenor,” he added.

Tips for diesel generator maintenance

D

iesel generators play an important role in many environments including schools and Government buildings, hospitals, events, construction sites and more – providing a backup source of power should the mains fail.

Whilst being a reliable and cost-effective source of backup power, neglecting proper care and maintenance of a diesel generator increases the risk of failure when they are needed the most.

Preventative Maintenance Tips for Diesel Generators Whilst a power failure is a nuisance for some, it can be devastating for businesses – bringing manufacturing lines to a halt and in some case forcing the closure of the premises. In addition to regular servicing of diesel generators by a professional, there are a number of checks that can be carried out to ensure your generator runs when you need it most.

Battery Inspections – When generators are left dormant for too long, batteries can fail during the start-up phase. Additionally, chargers, connections and cables can begin to deteriorate, preventing the required electrical current from being passed to the battery.

To prevent these kinds of failures, a visual inspection

CR | May/June 2022

should be carried out to check for any leaks, build-ups of contaminants and general damage.

Running the Generator – Even when a generator is not in use, it should be started regularly to prevent fuel from becoming stagnant and degrading. Should a generator be left for more than 6 months without being started, fuel testing should be carried out by a professional technician.

Fluid Checks – Diesel generators rely on fluids including coolant, lubricating and fuel to operate.

Levels of these fluids should be monitored regularly and topped up with the recommended liquid as per manufacturer instruction. Additionally, any leaks in the system should be reported and inspected by a professional technician.

Contaminant Checks – Contaminants found within coolant, lubricating oil and fuel can all causeserious issues within the generator. Inspect your fluids regularly with a dipstick and run the generator at recommended intervals to avoid any stagnation. If you notice any unusual results, call a professional to inspect your system.

Control Panel Checks – Before startup, the control

GENERATORS

panel of the generator should be checked, this will give you an immediate of any problems within the system.

Before startup, ensure that ‘auto mode’ is on, this is one of the most common and easily avoidable reasons for generators not starting.

Recommended Servicing Frequencies for Diesel Generator The recommended frequencies of servicing for a diesel generator will be dependant on its usage and running time. As a rough guide, you should aim to have a full inspection and service of your generator once every 6 months or at 400 hours running time.

Carrying out regular visual inspections enables you to keep on top of any faults within your system and may demand a service sooner than expected, some of the factors that may result in more frequent maintenance include: Environment – Exposure to extreme temperatures and weather can damage components of the generator.

Should your generator be in a coastal environment such as a port or shipyard, care should be taken to prevent excessive exposure to salt water carried in the winds.

Contaminants – Airborne contaminants such as dust and sand may infiltrate the generator, causing damage to its internal components. A generator on a construction site or similar environment may require additional servicing.

Excess Usage – Most diesel generators are designed to provide backup power. Should a standby generator be used for prime power, care should be taken to ensure the generator is inspected frequently and only used for as long as is required.

generator, clear and unobstructed access should be available for servicing, refuelling and inspections.

•Generators vibrate when in use, creating lots of noise. Should your generator be running near a residential area, consider vibration isolators to prevent noise pollution.

•Avoid placing the generator in an area that is at risk of flooding, strong winds or snow drifts.

Lack of Usage – Similarly, if a generator is left dormant longer than expected, engine exercise should be carried out to avoid battery failure.

Standby Generator Placement Tips Placement of the generator is something that should be carefully considered to prevent any complications when in operation or being serviced. Our top tips for proper diesel generator placement are: •Ensure the generator has an adequate and unobstructed source of power – requiring excess wiring and piping can drive up costs and reduce efficiency.

•Generators require an adequate intake of air to ventilate properly. Additionally, generators give off exhaust fumes which can be unpleasant and harmful to health – ensure that your generator is placed in an open space with an adequate source of air.

•A canopy or guard may be erected in order to protect the generator from weathering.

•Accessibility must be considered when placing your

TECHNOLOGY

Remote construction technology trends today

C

onstruction technology is a term used to define the different technologies used to enable remote construction within the industry.

The world is rapidly changing, and factors like a pandemic, high labor costs, etc., all acted as a pioneer in the need for remote construction.

Contrary to popular belief, construction sites are one of the most innovative areas of profession out there. The construction industry has always come up with the most viable options for adjusting to the economic, political, and environmental factors.

Virtual and Augmented Reality One of the most significant scientific breakthroughs in the past decade is virtual reality (VR). The technology coupled with Augmented Reality (AR) has allowed people to accomplish much more than additional design options.

Following are some of the most common tasks that the VR and AR technologies can help with the isolated construction projects: Eliminate bottlenecks A bottleneck is congestion in the production process of any niche. Bottlenecks in remote construction projects are a significant problem because it impacts the project timeline collectively. There’s a wide range of negative impacts on remote construction projects that you may face.

22

For instance, you may have to pay more costs for the project, bear a more extended milestone completion than the initial estimation, and much more.

Using the VR and AR technologies in these construction projects makes it easier to assess the projected trajectory and remove possible project obstacles before initiating the line.

Improve Collaboration Remote construction requires higher collaboration between various construction departments. The VR and AR technology allow members to allocate resources for maximized collaboration. The increased collaboration also enhances the outcome of the remote construction projects by maximizing operational efficiency.

Virtual Inspections Virtual site inspections are one of the biggest obstacles for remote locations. There are many risks, resources, and time involved, but the VR and AR projects provide on-time site updates virtually.

The technologies have become a must for the construction and design industries to ensure better results. Even simple components like a 3D camera allow the creation of the most detailed outline and progress of the project through 360 o real-time video streaming.

3D Printing 3D printing is another popular technology that has helped revolutionize the world of

CR | May/June 2022

remote construction. 3D printing provides a layer-by-layer method of creating 3D models of construction sites. There’s a wide range of benefits that using 3D-printing technology in construction can provide. Following is a list of the most common ones you will identify in the construction process.

Reduces Material Consumption Decreases Construction Time Improves Sustainability Lowers Labor Requirements Minimizes Logistical Demand Optimizes Design Reduces Costs for Conventional Construction 3D printing ensures that the remote construction processes work efficiently and the project sustainability improves. It can also help assess and recalculate the labor costs and allocate resources accordingly. There’s a high chance of design flaws, which might increase the overall design costs and time frame.

However, testing the site model with a 3D design ensures that project owners reduce costs for conventional construction projects by reducing the construction time on each project.

You can also reduce the material consumption for the construction project and increase the profits and design efficiency reaped.

These benefits make 3D printing the best option for isolated or expeditionary environments where one cannot use the conventional methods for construction. Assembling a property or www.constructionreviewonline.com

TECHNOLOGY

construction project through 3D printing can take a few hours rather than full-fletched months to complete.

Drones and Aerial Data Drones are an excellent option to infuse in many industries, but the construction industry has shown the best results.

These drones provide access to the most remote locations in construction sites and allow aerial data collection through different resources. There’s a wide range of options.

Increase Safety The drones can perform a site inspection to identify possible safety hazards for the labor before the project begins.

Managers can easily map out their sites and take necessary safety steps to ensure on-time project completion.

Increasing safety measures ensures safeguarding lives and avoiding unnecessary legal complications such as lawsuits and construction code violations.

Save Time and Resources Assessing the construction site with a drone allows for mapping out the most suitable methods for the project completion. It helps allocate the right amount of time and resources for maximized efficiency and profits. Remote construction managers can even use drones to monitor the construction progress.

It can also help with the more dangerous project. For example, professionals working on a remote (a skyscraper project or a desert-based) project may not have excellent communication.

These devices provide global connection and communication projects to keep a consistent check on workers, managers, and on-site members.

Robotics Like drones and aerial data, using robots in remote construction is another increasingly popular trend globally.

These robots can help accomplish several simple tasks such as: Bricklaying Bulldozing LoadingPainting

believe robots might replace humans as resources in the industry if the testing is successful.

However, more development is required for robots to take charge of remote construction projects fully. Most of these robots still require a lot of human programming, input, and monitoring for long-running projects.

Bottom Line A wide range of construction technologies can make the process quicker, faster, easier, affordable, and ideal for longterm use. However, most remote construction projects need consistent planning, monitoring, and supervision for quicker project completion.

These robots make the remote construction process safer as well.

Many scientific and research facilities are working on prototypes for remote robot construction workers. Experts

Fast-Track Surveying Surveys can help update the project management plans on time and achieve milestones in a shorter period. There’s a wide range of fast-track surveying options that you can choose from. Quicker surveys ensure real-time aerial data updates for accurate outcomes.

Radio Satellite Technology Radio satellite technology in construction ensures that all remote projects run through structured communication.

The biggest obstacle for remote construction projects is maintaining contact between the on-site and off-site resources.

For instance, a remote construction manager may need real-time on-field updates from laborers or other workers.

In other cases, the project managers may need to warn the workers about an imminent construction threat because of a geographical threat.

It allows consistent communication between site-based and office-based project members for better collaboration. It can also aid camp communication, distress calls, encrypted communication, durable device protection, etc.

It is the most viable method of communication in these remote construction projects and keeping a check on the group and individual resources at all times.

FLOORING

Different Types Of Floor Scrapers & Tile Removers

W

hen removing flooring, it's essential to incorporate the right tools and equipment to ensure the work is less time-intensive and requires less effort than it needs to.

No one wants the potential for a back injury because their equipment was less than adequate.

One of the primary pieces of equipment to remove the layers of material with the flooring is a scraper or tile remover.

Others include scabblers, scarifiers, and grinders.

The equipment you need will depend on the sort of job you have and the size. The important thing is to familiarize yourself with the piece before applying and using it safely. Check out the use and purpose for each of these individually.

Convenience is when you are able to choose the type of tool specific for the type of surface. Use the perfect scraper to make sure you do not cause damage to the surfaces.

Scrapers and tile removers Floor scrapers and tile removers mean to help homeowners and businesses remove layers of old flooring, whether it's wood flooring, tiles, vinyl, linoleum, or carpeting, with the capacity to accommodate any structure with either electric, battery, or propane operation. Go here for guidance on removing glued-down wood flooring.

CR | May/June 2022

The sizes vary according to specific needs, with unique features available for particular circumstances and needs. You'll find models meant for DIYers or light commercial duty to more industrial, professional-size, higher-volume projects.

The equipment comes for ride-on use, walkbehind, or hand-held. Of course, the hand-held will be the most straightforward and affordable of the three, but these are for small, confined spaces since the labor would be intensive.

Ride-on is the favored of the three as the most productive and capable, with the ability to whip through over 100 feet of flooring in only a minute.

It's suggested to obtain training if you've never used the equipment.

Scabblers and scarifiers These pieces of equipment also reference as concrete planers. Each of these is a walk-behind and has a unique application.

Scabbling roughens a concrete surface by removing a thin layer in order to get a better grip. The process is used to get surfaces ready for numerous purposes, including grouting, coating, sealing, repairs, and painting.

You can also use it for an aesthetic effect. It's also ideal for taking off surface contaminants, a top layer of coating, or any sort of adhesive. Scabbling equipment offers varied "heads" that have steel or "carbide" tips with the capacity to provide over 1000 hits each minute to make quick work of a project.

so the project goes smoothly with minimal challenges throughout the process.

Scarifiers are made to "scar or cut" concrete surfaces using rotating cutting tools that turn around a drum. This equipment removes the concrete at a much more aggressive and quicker pace than what grinding equipment does. A rough surface is the result that some coatings need in order to bond completely.

Always consider key factors when choosing construction equipment like floor scrapers. It needs to be functional especially in the type of environment this type of tool will be used in.

Scarifiers are used in numerous applications such as sidewalk grooves, coating removals like traffic lines on motorways, ensuring slip-resistance for sidewalks, and on.

Grinders Abrasives are used with grinders when attempting to remove the concrete surfaces for a new installation in a commercial setting. This equipment works to remove surface-level materials, including adhesive.

Without adequate equipment, flooring removal can be a back-breaking, time-intensive job. It's wise to invest in the best tools to do the work right from the start.

For example, in a large space such as a parking lot a warehouse, or a convention hall, a ride-on scraper is the most efficient choice and the most comfortable option for the operator. If working in much smaller spaces like bedrooms, house rooms, offices, or clinics, a walk-behind scraper is typically more convenient.

Do remember that before you begin scraping away, prepare the surface first. Remember that using the right tools and making correct preparation is critical to a successful project.

It has the capacity for polishing specific materials like concrete and can perform industrial duties such as leveling high spots.

If you're unsure which sort of grinder you need for your specific job, it's better to reach out to an expert for guidance.

The professional can ask and answer specific questions to lead you in the right direction and also help with adequate training for those who haven't used the equipment previously.

Whether you're engaging in a household DIY project or have a heavy industrial job that needs to be handled, there's a piece of equipment that can help you with removing any sort of flooring material, the surface layer of concrete, or coating with ease and in a timely fashion.

IT SERVICES

How Construction Firms Benefit From Managed IT Services

I

nformation technology (IT) is a crucial aspect for most firms.

You need technology to send documents, communicate, store data, etc. Most industries have adopted IT in their operations on a large scale, with other industries, such as construction, believed to be lagging. There are many ways you can handle the IT aspect of your operations; the two major ones being hiring an in-house managed IT services team or outsourcing. Each of these has its advantages and disadvantages.

Do you run a construction company? Are you wondering which of the two options you should adopt? This article will help you decide by discussing how managed IT services will benefit your construction firm. Read on for the answers.

Access To Technology Today, most companies rely on technology in running their operations, your construction firm included. But, technology keeps changing, and you might find it challenging to keep up due to a lack of financial resources and time.

A managed IT team that serves construction companies will ensure you’re utilizing the latest technology to ensure efficiency.

Since they serve the construction industry, they know your needs and will suggest the best tools you should adopt. Depending on the tools you choose, they’ll ensure they run well to ensure your operations run smoothly. You may check this out and other similar sites if you want to learn more about managed IT companies serving the construction industry.

The construction process involves many parties. Thus, they should be in sync with one another to ensure any information gets relayed in the right manner despite these parties’ geographical locations. The outsourced IT team will design your tools to allow remote access to data, with others providing hardware, such as mobile phones, to allow for smoother communication.

When working independently, you’re likely to find it challenging to adopt such systems.

Reduced Downtime Downtime is any company’s worst enemy. During this time, most operations are dormant, reducing income. In the construction industry, downtime means a delay in giving clients deliverables, which isn’t desirable.

Managed IT services can help reduce your construction firm’s downtime. How? Most outsourced IT teams adopt a proactive approach to managing your operations. Through this approach, they’ll perform periodic preventive maintenance, which enables the team to identify and rectify any possible source of issues.

Therefore, in no case shall you experience unexpected breakdowns. Your construction team will always be working on designs, holding virtual meetings, etc., without interruptions.

32

CR | May/June 2022

However, it’s good to acknowledge that even with all measures in place, issues may arise. Should they arise, your managed IT team still got you covered. Since they’re experts in the field, they’ll promptly solve your issues. You’ll resume operations within no time.

Increased Security Security has become an issue in most companies with the rise in digitization. Hackers are taking advantage and using digitization to steal data through networks and the Internet. As a construction firm, data theft is a sensitive matter. A hacker could steal your designs before implementing them and sell them to your competitors. This isn’t good for business.

A managed IT team increases the security of your firm. As part of their proactive approach to fulfilling your needs, most will give you 24/7/365 support. They’ll monitor your systems to identify any suspicious activity. This team will counter the attack and revamp your systems to prevent future occurrences if there's any suspicious activity.

As previously stated, breaches can occur even with security measures in place. It’s best to be ready for such an incident; the outsourced team will help you be ready. This team will prepare an incident response plan, which contains details of how they’ll retrieve the stolen data, in order of importance, including the communicawww.constructionreviewonline.com

IT SERVCIES

tion chain. In most cases, there’s a likelihood of confusion after a cyberattack. Confusion is likely to make things worse, so it’s important to have an incident response plan as it keeps everyone on track.

Reduced Operational Costs Running a construction firm consumes many financial resources, from the building process to paying workers on-site and suppliers. You want to keep your expenses to the bare minimum. An outsourced managed IT services team can help reduce your expenses. How? You’d have to hire an entire in-house IT team without the outsourced team. This team will require you to pay more wages, insurance coverage, and other benefits. You also have to invest in extra office space to accommodate them, increasing your rent. The team also requires equipment to fulfil their responsibilities, which is an added expense. All these costs cumulatively make a great impact on your profits as a con-

How convenient is your concrete mixer?

M

any contractors always find it advantageous to have their own concrete mixer as opposed to depending on outside vendors and if you are a new entrant to the construction industry it is an investment worth making.

While weighing on whether to call on ready-mix concrete delivery or owning your own mixers, many factors should be weighed. These include among others, job scope, the location of the site, size and quality of staff and the time frame attached to the project.

For instance, it is counterproductive for a contractor to use a portable concrete mixer when he needs to pour a slab of 50 square metres. He is much better served using readymix. Similarly, if a job needs to be completed in an hour so contractors can move on to the next job, ready-mix is a smarter choice. Nevertheless, according to Stefano Tognoloni of Concrete Mixers s.r.l in Italy, your mixer of choice should ensure very high reliability, independence, and flexibility in working time.

In-transit Mixers In-transit mixers are made to transport and mix concrete up to the construction site. They can be charged with dry materials and water, with the mixing occurring during transport. They can also be loaded from a ‘central mix’ plant, with this process the material has already been mixed prior to loading. The concrete mixing transport truck maintains the material's liquid state through agitation, or turning of the drum, until delivery.

The interior of the drum on a concrete mixing truck is fitted with a spiral blade. In one rotational direction, the concrete is pushed deeper into the drum. This is the direction the drum is rotated while the concrete is being transported to the building site. This is known as ‘charging’ the mixer. When the drum rotates in the other direction, the Archimedes' screw-type arrangement ‘discharges’ the concrete out of the drum. From there it may go onto chutes to guide the viscous 34

concrete directly to the job site.

If the truck cannot get close enough to the site to use the chutes, the concrete may be discharged into a concrete pump, connected to a flexible hose, or onto a conveyor belt which can be extended some distance (normally ten or more metres). A pump provides the means to move the material to precise locations, multi-floor buildings, and other distance prohibitive locations. Buckets suspended from cranes are also used to place the concrete. The drum is traditionally made of steel but on some newer trucks as a weight reduction measure, fibreglass has been used.

Advantages The biggest advantage of transit mixers is that these do not allow segregation of concrete because of continuous rotation. Unloading of concrete batch can be done at will in full or partially.

According to Brett Fillmore of ProAll Reimer Mixers in Canada, modern job site characteristics cause great challenges for traditional concrete delivery methods.

However, having a concrete mixer onsite means concrete is mixed fresh no matter where you are. There is no wait time, and materials are mixed only when you need them.

Drum of concrete mixer does not allow any foreign material to enter the concrete load. Concrete can be unloaded to a conveyor belt, a concrete pump or into the chutes. As the capacity of available transit mixers varies from 4 cubic metres to 12 cubic metres, choice is available as per site requirements and concrete production rate.

More advantages include: vast improvement in the quality and uniformity of concrete and enhanced speed of construction; savings in labour, reduction in wastage, elimination of material procurement requirements and storage hassles; plus the environmental conservation aspect www.constructionreviewonline.com

whereby the surroundings of the site remain clean.

According to Manuela Galante the Marketing Director at Carmix, the in-transit mixers have the ability to mix, transport and deliver any kind of concrete directly in the jobsite, in any condition of work, latitude and clime, allowing the user to control the cost and the quality of each single cubic meter of concrete.

Portable Mixers The smaller models which are normally available in sizes ranging from 3 to 12 cubic feet; will fit in the trunk of most cars, while the larger capacity units can be towed easily on wheels or hoisted onto a truck for longer distances. With their small size and easy portability they can be used even in remote areas that characterize most African settings.

To a budding contractor wishing to establish himself but facing financial constraints, this could be a perfect start up as their costs are quite accommodative.

Advantages The biggest advantage in owning a portable mixer is realized when working on sidewalks, foundations and binding block, and when preparing mortar bases. Many decorative concrete contractors find the portable mixers ideal too. A good example is the monument works industry which mostly has mixers mounted on their own trucks. The same holds true for many landscape and fence builders.

One interesting model of portable mixers is the wheelbarrow-style mixer that fits comfortably through a 30-inch-wide opening. This allows the user to mix and pour right where the product is needed.

On the other hand contractors working in a back yard or space-restricted area where accessibility is a problem

will find a portable mixer much more effective. Smaller mixers are highly recommended for mixing concrete to anchor fence posts; for patching; for small concrete slabs on grade; and for mixing non-stick grout.

For high-production jobs such as concrete slabs, sidewalks and block walls, larger-capacity models are better suited. There are many styles and sizes to choose from, from a 2-cubic-foot pedestal style to a 31⁄2-cubicfoot wheelbarrow style to a 9-cubic-foot towable unit. The utility mixers start at 11⁄2 cubic feet and can be mounted or be made stationary; or an optional low- or high-speed tow kit can be added.

The mixers come with either electric- or gasoline-powered sources. Single-phase electric motors are available in the 1⁄2- to 11⁄2-horsepower range while gas engines span from 3 to 13 horsepower. Mixers also have speed controls that can be adjusted to fit the requirements of the specific job.

Most manufacturers offer steel and polyethylene drums to fit individual user preferences. Steel drums are more durable, but cleaning can often be tedious and other damage to the drum is a possibility. Poly drums, which resist rust, can be cleaned in minutes by simply tapping with a rubber mallet and they are lighter than their steel counterpart.

Choosing you mixer The nature and volume of work is a factor to consider in choosing the right mixer. Big-scale construction projects require bulk concrete mixers which can mix large quantities of concrete both onsite and offsite. For small scale projects, smaller mixers can apply. The size of construction site is a major factor to consider. Remember smaller mixers can fit well in squeezed sites while large open sites can comfortably accommodate the bigger ones.
