MARK WIJNBERG LAND SURVEYORS
We have many years of experience in the surveying industry, with our focus being on topographic, aerial, cadastral and engineering or construction surveys.
Our aim is to provide a land surveying service that is both accurate and fast to benefit the client. Our broad understanding and experience in the industry enables us to meet these goals. Whether the survey is beneath the earth’s surface or up in the sky – we will take on the challenge and get it done accurately and in the fastest time possible. We also understand that Earth’s natural resources need to be respected, therefore land surveying in South Africa, and throughout the world, should always be done by professionals with great care
A BIT ABOUT US
Mark Wijnberg Land Surveyors started in 1996 and is based in Kloof, Durban, servicing Kwazulu-Natal originally, but now all parts of Africa. We offer accurate and professional surveying services, specialising in cadastral, engineering, construction & land development projects.
Our professional land surveyors and experience provides a full range of services, including boundary & site surveys, land subdivision & planning, engineering & construction surveys and development consultancy.
We use the latest surveying technology and CAD software to provide fast, accurate and efficient results
Property subdivision can be beneficial in many ways, such as reducing debt for homeowners by disposing of a portion of their land, and thus reducing their bond repayments and property rates. It is also a good way of improving security in a security conscious country, by living in a more confined space, with neighbours close by. We provide all necessary services – from feasibility studies and initial application, to final survey and registration documentation.
BOUNDARY PEG RE-ESTABLISHMENT
Boundary peg or beacon relocation is the process of reconstructing the position of the property beacons and boundary. This process is carried out by our registered surveyors and is accompanied with beacon certificates.
Encroachment or boundary dispute surveys detail the extent and possible remedial actions in order to establish the boundary lines.
SECTIONAL TITLE SURVEYS
When someone purchases a sectional title property, they do not purchase just the area that they will be dwelling in, but also a section or portion of shared property that is part of the communal area of a shared property. This usually applies to flats or complexes, where there is a communal pool, clubhouse, mailbox etc. This means that the owner takes responsibility for paying a portion (levy) towards the use of these communal areas under their sectional title.
We undertake the creation (and, subsequently, amendments and extensions) of Sectional Plans and associated documentation for lodgement and approval by the Surveyor General.
ROAD & RAIL CONSTRUCTION SURVEYS
Surveying plays an important part in road and rail construction projects, in that it assesses the conditions for construction, before, during and after to ensure correct measures have been set out.
When compiling a road or rail survey, usually a topographic survey is done initially to determine the location of alignments and record the volumes materials of the earth that need to be added, removed, or moved. For larger areas of land, a photogrammetric survey is done, to develop the base map for the project.
In rail construction more specifically, it is necessary to determine all possible routes, costs, gradient and curvature of the land, if it is necessary for cuts and fills, and the location of bridging and tunnelling. We also determine the trial lines, the precise measurements of distances, directions and altitudes.
Once construction has been completed, and ‘as-built’ survey is done to assess any modifications to the original planning.
BUILDING/STRUCTURE MONITORING SURVEYS
Using specific survey instrumentation, we run high accuracy, long term monitoring surveys of buildings and structures such as dam walls, to detect whether movement has taken place. This is done before construction takes place, during the construction process and once the construction has been completed. Building or structure surveys are important to determine early detection of movement in structures and buildings, so that the engineers and builders can then make informed decisions on what measures to take regarding the engineering requirements.
Survey can be used to determine and quantify the extent of deformation or difference of features such as road, building or structural shifts. The specific points of the different features are determined, then a certain amount of time is allowed to pass before re-measuring and calculating, after which a comparison between the two surveys is done to determine the differences.
A topographic (or tache) survey is used to determine the relative locations of places on the earth’s surface, such as boundaries and buildings, by measuring horizontal distances, differences in elevation and which direction these are facing.
We compose surveys drawings detailing the features and the lay of the land, such as trees, banks, roads, municipal services, contours, levels, building footprints. This serves as a base map to be referred to when working with the design of different types of buildings, either residential or commercial, or when designing roads or driveways.
SOME OF OUR RECENT WORK
CADASTRAL SURVEY OF ADMINISTRATION AREAS IN RURAL EASTERN CAPE
Department of Rural Development and Land Reform required various administration areas to be formally surveyed and present government facilities such as schools and clinics to be identified and formally surveyed. Some of the proclamations describing these traditional areas are close to 100 years old. Much discussion and consultation with tribal leaders in the areas as necessary to determine the exact boundaries.
AERIAL SURVEY IN RWENZORI MOUNTAINS, UGANDA
Mark Wijnberg Land Surveyors completed an aerial survey of a river valley in a remote section of Western Uganda. The area is found on the Eastern slopes of the Rwenzori Mountains, close to the Congolese border.
The purpose of the survey was to determine the feasibility of the construction of a hydro-power plant and its environmental and social implications.
TOPOGRAPHIC SURVEY OF GAMBIA RIVER WEIR SITE IN MALI
Mark Wijnberg Land Surveyors undertook a large survey in rural Mali for a proposed weir site on the Gambia River. This river separates Mali from Senegal and require control to be extended from over 150km away to the site to be in line with local geodetic systems.
SURVEY OF VARIOUS ROADS IN BERGVILLE
This project involved mapping of 25 rural roads in the Bergville area, Drakensberg, South Africa for upgrade purposes.
The roads totaled more than 55km, each section approximately 5km. The client required the project to be completed in 4 weeks. Even with the traditional Drakensberg afternoon storms, Mark Wijnberg Land Surveyors managed to complete the project in 15 days.
TOPOGRAPHIC SURVEY IN ZANZIBAR
Mark Wijnberg Land Surveyors was approached to assist in a topographic and bathymetric survey of 2000ha in Northern Zanzibar . The site was proposed as a resort development. Clients required contours, levels and all topographic details of the site.
A fixed wing mapping drone was used to collect terrestrial data, while a side scanning sonar device was deployed to map the sea floor.
