Durban Golf Day postponed to 24 October 2017

The ASAQS KZN Chapter Annual Outreach Golf Day 2017 planned for 12 October has to be postponed due the extreme weather conditions experienced in Durban yesterday.

Royal Durban has been forced to close the course due to severe flooding. This has unfortunately lead to the postponement of our Golf Day. The new date will be Tuesday the 24th of October, 2017.

Again, apologies for the inconvenience and extremely short notice, however the event will take place on the stated date and we trust that we will see you there! Please note that this was out of our control and we thank you for your understanding.

Information required to do accurate estimates

What information do you need to do an accurate estimate of construction cost?

Do you wish you had a check list that enables you to ask the right questions from the architect and engineer?

Look no further than the sundries section of the Members Only CUG.

This check list was provided to the ASAQS by one of it's long-standing members, QS2000. Members are welcome to use the check list and we thank QS2000 for sharing it with their fellow-quantity surveyors.

Get your Excel-based Cash Flow Simulator now

Enhance your cost-reporting with our new cash flow simulator. It compares the current expenditure on a project with theoretical expenditure based on a standard s-curve.

It was designed by Mr Ian van Zyl, winner of our competition to find someone who could do magic with Excel.

We believe that the 2017 cash flow simulator will find wide use on government- and other projects as a simple tool that graphically indicates actual- against projected cash flows and also uses linear regression analysis to predicts the actual completion date based on current progress.

Max Wideman defines an s-curve as: "...a display of cumulative costs, labour hours or other quantities plotted against time. The name derives from the S-like shape of the curve, flatter at the beginning and end and steeper in the middle, which is typical of most projects. The beginning represents a slow, deliberate but accelerating start, while the end represents a deceleration as the work runs out."

Why use an s-curve? It's an important project management tool that allows the progress of a project to be tracked visually over time. To find out more uses of the s-curve watch the video on this page. By watching the video you will also learn about more sophisticated uses of the s-curve such as "banana" curves based on the early- and late dates of the schedule and how this is used to keep tabs on project progress.

The new Cash Flow Simulator 2017 edition is a basic tool which is especially useful in circumstances where the contractor cannot produce a proper schedule indicating the critical path of the project. It is available from the Sundries section of the Members Only CUG. Members can use it freely and firms are allowed to co-brand it by inserting their logo's along with that of the ASAQS on the simulation page.

Please note that the simulator may not function as intended on older versions of Excel. The Excel workbook was zipped in order to load the .xlsm file into the file library and members will have to unzip the file before use. We also strongly recommend that you read the instructions before inputting your own data into the simulator.

We look forward to hearing from you after using the simulator and will be guided by your suggestions in future enhancements and improvements to the simulator.

Curb construction project costs through value management

Improvements in the construction process as well as the function of a building can be achieved through a highly underrated process called value management.

The value management process is ideal to improve a project’s function, streamline the construction process, highlight potential future problems and reduce capital costs as well as operational expenses in all spheres of construction: civil, industrial, mining, and energy projects, to name a few.

 Mr Chris de Wet

“Value management is a broader view of the better-known term value engineering,” explains Chris de Wet, Value Management Advisor at the Association of Quantity Surveyors of South Africa (ASAQS).“It is a process that can determine whether a different way of designing, constructing, procuring and thinking is needed.”

The process includes a complete value analysis of all components as well as the consideration of alternative material and process selection. It should ultimately result in savings and operational efficiency that ensures the client derives the most financial value from a project.

Stainless steel has crucial role to play in solving SA’s water woes

Globally, as much as 35% of all treated water is lost to leaking piping systems with South African levels reaching as high as 60%. This has prompted a stainless steel test project to get underway in Paarl between the Southern Africa Stainless Steel Development Association (sassda), local municipal authorities and South African manufacturers in search of the most environmental and economic solution for the country’s water-wise future.

Case studies show that 95% of treated water leaks occur in the small diameter service pipes connecting the distribution pipes to the users’ water meters. Currently, approximately 40% of Johannesburg’s treated water supply is nonrevenue water (NRW), equating to a loss of R1.1 billion per year, of this 73.3% is lost due to pipe leakage.

Sassda Western Cape Manager Michel Basson says this is because water pipes are currently made from, or replaced with, High Density Polyethylene (HDPE), with a lifespan of 20 years, as opposed to stainless steel applications of at least 60 years. “In light of this, we currently have a test installation underway in a residential unit in Paarl where we are evaluating the installation of corrugated stainless steel tubes connected to the bulk supply line, which have been installed and covered in such a way that they can be easily removed for inspection.”

Focus on learning the skills that impact performance on construction sites

says Alusani® Course Leader

At the start of their careers, few construction site managers realise that they will need to be part magician, part musical conduction and part superhero. Effective construction site management requires a broad range of skills, from technical expertise to leadership, negotiation, team building, communication, and everything in between – but few construction site managers are equipped with these skills when they arrive on site.

Deon van Heerden, Alusani® Course Leader, says that empowering yourself with the required tools, knowledge and skillset can help overcome a number of challenges that are typically experienced on construction sites. Some of these challenges include improper risk management systems, poor communication, dealing with tight deadlines and lack of engagement from all stakeholders.

“Risk tolerance, for example, is a desirable trait for a construction site manager because projects rarely go exactly as planned. Having the right skills to manage quality, cost, scheduling, disinterest from certain stakeholders or vendors, and dealing with declining morale thanks to impossible deadlines can not only boost your risk tolerance, but it will help you develop contingency plans to deal with problems if and when they arise. Many construction site managers simply haven’t been exposed to adequate cost control, quality control and materials management systems, which are crucial to successfully completing a project in time,” says van Heerden.

Another important skill that is often lacking in the sector is proper site planning and layout. If this isn’t done properly, then everything from material delivery to site access for all the workers can quickly become a problem that will fall into the construction site manager’s sphere of responsibility.

“Construction site managers, site supervisors and team leaders can gain priceless insights from attending a course on construction site management. Besides learning new ideas and approaches to making their projects more effective and efficient, they also benefit from networking with other people in similar roles within the South African built environment. It will also help them prevent expensive time and cost implications by learning how to control the three biggest factors that impact their performance, namely manpower, materials and equipment,” says van Heerden.In the course that van Heerden presents on construction site planning, some of the topics that are covered include how to go about establishing a construction site, manage construction site teams, resolve conflict on site, why planning and scheduling is important (and how to do this effectively), document and drawing control, material management, and construction quality control systems, among other vital topics.

“One of the not-to-be-missed discussion topics that will greatly benefit construction site managers is a portion that we dedicate to health and safety regulations. There are so many different types of regulations and laws, and this course will give clear guidelines on the ones that you need to focus on specifically,” concludes van Heerden.

Van Heerden will be facilitating the Alusani® CPD-accredited Construction Site Management on 23 & 24 November 2017 at Melrose Place Guest Lodge in Johannesburg. A number of Alusani® CPD accredited courses that are held throughout the year. For more information, visit

Information sheet on the classification of soil compaction

The objective of this information sheet is to provide clarity regarding soil compaction classification and to broaden the readers’ understanding of process and the terminology used within the industry.

Compaction is the process whereby particles within a soil sample are pressed closer together to increase the interlocking properties between this, a force (impact, rolling, vibration) is needed to overcome particle resistance and densify the material.

The efficiency of this process is dependent upon the compacting effort applied to the soil, as well as the inherent friction between the various size particles within the soil sample. To increase compaction efficiency and reduce friction of particle resistance, water is added as a lubricant. The amount of water required is determined from laboratory tests and is referred to as the optimum moisture content (OMC), which is a percentage of the soil’s mass.

In general the following relationships can be found between compaction effort and moisture:

  • Using a large force requires less moisture
  • Using a small force requires more moisture
  • Coarse material requires less moisture
  • Fine material requires more moisture
    Density is one of the key measures used when analysing compaction efforts and efficiency in the field, thus it is important to understand what density refers to.
    What is meant by the density of soils?

Density is a measure of the degree of the togetherness of particles within soil and highlights the interlocking capability of the soil. It is defined as dry density when only the mass of the solid particles per unit volume of the soil is measured and wet density when the mass of the water is also taken into account.
