Crafting creative floors for commercial spaces
PPPs can be the answer to Africaâ&#x20AC;&#x2122;s developmental funding headache

wealth of benefits, as its design can help to create a vibrant and engaging customer experience.
However, a lack of modern infrastructural developments is a major challenge to Africaâ&#x20AC;&#x2122;s economic development and constitutes a significant impediment to the achievement of Sustainable Development Goals (SDGs).
Heard of surfactant leaching?
Given the colossal sums required to fund these developmental projects, an increasing number of countries, notably emerging markets and developing economies (EMDE), are turning to Public-Private Partnerships (PPPs) in order to tap private capital.
Surfactants influence a range of properties in paint including paint colour and stability, but are not always effective in every application.
Although PPPs cannot fully solve this problem, they can provide significant financing where viable projects are carved out. Despite the fact that some African countries are hesitant to embark on PPPs as a result of prior bad experiences with ill-prepared PPPs or even with less-than competent PPP project sponsors; there are ample PPP opportunities waiting to be realized on the African continent for the benefit of all stakeholders.Governments therefore need to urgently put in place an enabling environment in order to attract more private participation if SDGs are to be met.

Cifa and Euromecc join their forces in the batching plants industry
Phanes Group kicks off solar incubator programme in subSaharan Africa Cifa and Euromecc , two leaders in the batching plants industry have entered into a technical, production, and commercial collaboration agreement.
Solar Park in Namibia has installed capacity of 6.5MW which supplies electricity to the largest Namibian cement factory.
GILDEMEISTER energy solutions builds solar park in Namibia
On 26th March 2018, CIFA, a company leader in the design, development, production, distribution, and sales of machinery for the concrete industry and Euromecc, a company specializing in the manufacture of batching plants signed a technical, production, and commercial collaboration agreement within the batching plants industry.
Dubai-based Phanes Group, an international end-to-end solar provider, has announced the 2nd edition of its Solar Incubator programme. The programme is aimed at identifying PV projects of potential in sub-Saharan Africa by providing commercial and technical knowledge support.
In contrast to many other parks of this size, the Ohorongo PV system does not feed the public grid, but directly supplies the neighbouring industrial customer, the largest cement factory in Namibia.
Therefore, the two leaders will provide a complete range of solutions to meet the requests of the most demanding customers and provide a complete service, from the design to after-sales, including installation.
The initiative held under the theme, “Your Project, Our Expertise, For a Sustainable Future”, will be held in collaboration with Hogan Lovells, responsAbility Renewable Energy Holding, RINA and Solarplaza, and invites PV developers to submit proposals for projects based in sub-Saharan Africa that have a clear corporate social responsibility (CSR) component.
20,000 solar modules installed It is a tracked system with an installed capacity of 6.5 MWp. At the end of June, the 20,000 solar modules installed will go into operation and feed around 14 GWh electricity per year directly into the cement plant network.
The new range of products This new range of products will be distributed and sold under the CIFA brand and will replace CIFA’s and Euromecc’s existing ranges of products.
Candidates are asked to submit their proposals by September 27th 2018 (11.59 pm CET) via the process established on Phanes Group’s website.
Another large scale project has been realized in Namibia by GILDEMEISTER energy solutions.This time in Namibia. A total of 6.5MWp is provided by the solar park, which supplies electricity to the largest Namibian cement factory. In addition to the central activity as the general contractor, GILDEMEISTER energy solutions was responsible for the codevelopment of the project, developed by the German SunEQ GmbH as IPP.
Both Cifa and Euromecc will join their history, experience, and expertise, developing a new and more extended range of products with superior characteristics for stationary and mobile plants.

VINNAPAS® 760 ED VINNAPAS® 760 ED is a terpolymer based on vinyl acetate, ethylene and vinyl ester that can be used as a hydrophobic binder in two component waterproofing membranes such as sealing slurries. Together with ethylene, its vinyl esther component considerably increases the elasticity of the end product. As a result, the coating is more extensible and very flexible. VINNAPAS® 760 ED ensures outstanding crack bridging, even at exceptionally low temperatures down to -20 °C. Additionally, it is highly resistant to hydrostatic pressure.

Confirming the statement Segun Adaju, president of REAN said they are in talks with the bank adding that five companies including Abuja based Blue Carmel and Elec3city, have signed a memorandum of understanding to provide off-grid power to industrial and residential users respectively. Upfront costs involved in acquiring solar energy Segun Adaju noted that the challenge of huge upfront costs involved in acquiring solar energy is the strongest discouraging factor for rapid solar energy adoption in the country. To set up a 2KV system capable of powering a refrigerator, 5 lighting points, a television and sound system set; a user would be required to pay as much as US $2 in a three bed-room apartment. Systems that can power an entire building including air conditioners and pumping machine could cost between US $6K – US $11K. Considering that the lifespan of solar panels is over 20 years and good batteries can last up to five years, the cost over time is cheaper than buying diesel which pollutes the environment.

According to Brenda Martin, CEO of SAWEA, standardised employment metrics and methodologies should be used across all energy technologies. Such understanding can then usefully inform the planning choices that need to be made in the short term.
AAK calls for lawful demolitions The Architectural Association of Kenya (AAK) has called for ‘humane’ demolitions in line with the law following concerns of the manner in which ongoing demolitions of buildings on riparian and public land is being carried out. Emma Miloyo, AAK president urged the government to mind innocent victims such as second and third generation buyers and tenants who stand to lose millions of shillings during the demolition exercise. She also said conflicting legislation on riparian land such as the Survey Act, Agriculture Act and Water Act 2016 fueled confusion on the matter. “We support the efforts by the government to uphold the law as it is the only way we can operate as a civilized society and achieve the Kenya we want. However, the application of the law must be consistent and non-selective,” said Emma. Agencies behind the demolitions Emma Miloyo also raised concerned over the agencies behind the demolitions. She said that the same agencies were involved in issuing developers with the necessary regulatory and statutory documentation to develop the land. The agencies include the National Environment Management Authority, Water Resources Authority and the Nairobi City County. “Why did these agencies wait for these structures to be built only to then demolish them? A lot of uncertainty and fear has been set to get into the real estate industry as it is not clear anymore which permits are valid and there is no process to validate them either.
Structural transition She further added that globally, the power sector is undergoing a complex structural transition away from a model of regulated, monopolistic, centralised and coal-based electricity supply. www.constructionreviewonline.com

IMPORTANCE OF CLIENT RELATIONSHIPS IN CONSTRUCTION has changed significantly over the past 50 years. Historically, plant managers approached us with a single problem that they needed rectifying, such as a drive on a pump that was not working effectively. We are now being asked to look at the scope of a project on a much wider scale. Rather than installing one single piece of equipment, if the project requires it we develop a bespoke system that impacts on the overall facility.
close working relationship between client and contractor is important for any project success. But how do you manage client relationships without over promising? Dave Friar International Operations Director at engineering solutions provider Boulting Ltd explores the importance of building and maintaining a strong relationship with the client. The success of any engineering project often revolves around the quality of the relationship between client and service provider. A good working relationship should be based on trust and understanding between all parties and, if managed correctly, this can lead to a more permanent contract between all parties and, through good relationship management can be fruitfully beneficial to both parties for the longer term. Construction client management The services that engineers provide are often not judged until the end of a project or even for some time after. If you’re looking to improve plant efficiency by integrating automation technologies or design and build a new high voltage distribution network, the success of the project may not be immediately measurable. However, the client’s experience in ‘Word of mouth’ is very powerful in the industrial world, as it can both lead to new project wins or result in the loss of potential contracts. A client’s 8
Increasingly, clients are looking at the design and build of a facility as one single element, rather than breaking it into two. At Boulting, we provide both services, taking clients through the entire journey; from concept to creation. Concepts such as Industry 4.0 have led to a great number of new possibilities for the design and build of a project, and while clients may have an initial idea for a scheme, it is our job to help them shape and develop their vision into something that can deliver the results they require. experience will shape how they publicly talk about a project, even if the results are not yet available. While it does take time to build and maintain a strong working relationship, it is a cost-effective exercise that can improve productivity and efficiency. Equally, if not managed appropriately complaints and misunderstandings can have a detrimental affect on the relationship, costing both time and money. Building relationships With any new client or project, it’s important to lay the foundations and get to know who you are working with and build up a rapport by exploring how they like to work. Do they prefer weekly or daily calls? Perhaps they’d prefer everything to be done by email. Whatever the approach, it needs to be defined in the early stages. It isn’t just about a single client though. Building relationships with individuals, whether they are the decision makers or not, is equally as important. Some projects may span across continents and require conversations in various languages, which brings their own set of challenges, further emphasizing the importance of establishing strong communication channels. Communicating the project brief How we communicate with clients and maintain that healthy relationship
CR | September 2018
One way to manage larger integrated projects is by using building information modelling (BIM). By integrating information from a variety of sources linked with the construction or renovation of a facility, BIM allows for the creation of a digital model of the plant. The level of detail in the model is dependent on the chosen BIM level. BIM is a collaborative process that is particularly useful when working with modular builds on pre-fabrication sites. By using one digital model that all contractors have access to, you can ensure that all pre-fabricated components fit into the facility. Clients will also have access to the model should they require a more in-depth update on the status of a project. Client collaboration can also be achieved through integrated project delivery, an alliance between suppliers and the client that aims to integrate the best aspects of people, systems, business structures and practices. By using this system, clients become part of the team, ensuring all interests and objectives are aligned across every aspect of the project. Transparency is a key benefit of this particular model as costs, time frame and progress are shared among all relevant parties, creating a sense of security and involvement. There is no one single way to perfectly manage a client relationship as every project is different. Whatever model is chosen,communication remains key. While technologies such as BIM have a wealth of advantages, it’s important not to rely on technology and forget to simply pick up the phone and talk. www.constructionreviewonline.com

To understand how corruption occurs in the construction industry, it is important also to understand what influences the opportunities for corruption. There are various factors that may influence corruption these include the size of the contract, the complexity of technology used in the process, the type of sector involved, discretion of the tendering process, lack of proper financial control, restricted access to information, urgency to complete a project, and conflict of interest. Tendering The tendering process is perhaps the construction stage most prone to corruption as contractors can pay considerable bribes to be awarded a contract. Projects that attract large amounts of resources and funding
Projects that attract large amounts of resources and funding are particularly vulnerable to corruption incidences.
are particularly vulnerable to corruption incidences. This is because of the high returns it promises to the stakeholders involved, both in the private and public sector. Additionally, these large projects are in most cases divided into phases making it even more difficult to manage and follow the money trail and all the contract links along the way. This allows for more loopholes for corruption. The more unique the project, the more the chances there are for corruption to occur.

Accountability- It is essential to ensure that accountability measures are put in place that will ensure transparency in procurement and in public participation.

Demolition Technologies Demolition technologies have continued to evolve over the years in order ensure increased efficiency, cost effectiveness, improved safety. From conventional mechanical methods to pneumatic and hydraulic tools, non-explosive demolition, controlled explosives as well as remote controlled demolition systems, minimizing the overall impact on project schedule, cost and liabilities should be the top priority of the method chosen. Controlled Explosive Demolition Techniques Where space and conditions permit, it is often best to use controlled explosive methods as the primary demolition technique for large, tall structures, with mechanical methods used for secondary demolition of the structure and subsequent processing of the debris. In such situations the controlled use of explosives is supremely superior to any other

form of demolition, both in terms of safety and speed, as well as efficiency. It is accomplished in conventional controlled demolitions by the synchronized detonation of numerous small explosive charges, placed adjacent to support columns throughout the building. Through precise timing of the detonations of the hundreds or thousands of explosive packages, interior structures are destroyed ahead of exterior ones, pulling the exterior walls toward the central axis in a classic controlled demolition implosion. Presumably the detonations throughout the interior or exterior could be simultaneous, or marched up the building as it sinks into its footprint.
