3d Laser Scanning

noreply@blogger.com (searchfirst) — Fri, 23 Oct 2009 13:30:00 +0000

Using a Leica 3D laser scanner we are now able to scan our building surveys to the highest degree of precision and level of detail. The three dimensional data can be edited in AutoCAD to produce traditional line plans or alternatively issued very quickly as rectified orthometric imagery. Any dimension or level required can be annotated by the click of a mouse. The pictures below shows a couple of 3d scan examples which were taken at a mansion building in Hertford near London, UK by ALS.

A building's internal and external survey are just one sector of 3D laser scanning potential. ALS can use laser scanners for historical records, forensics, three dimensional street scenes, topographical land surveys (including highway surveys), excavation monitoring pipe work for the oil and gas industry or for coastal monitoring surveys.

Please contact us for more information or quotation by clicking on this link "3D Laser Scan Enquiry". We do also have further examples of the 3d laser scan images on the following web address: http://www.laser-scanning-buildings.co.uk. Thank you.

Lease Plans

noreply@blogger.com (searchfirst) — Fri, 23 Oct 2009 09:56:00 +0000

Since the Land Registration Act 2002 came into force in October 2003 many commercial landlords and business owners were forced to register their property with the Land Registry. The new regulations determined that new leases with terms lasting in excess of 7 years, or existing leases sold with 7 years remaining were the ones to be registered. One aspect of the registration involves the submission of a lease plan compliant with the Act.

Anglia Land Surveys can assist you with lease plans which satisfy the requirements of the Land Registration Act 2002. The following list details these requirements:

* Lease plans to be drawn to a metric scale (typically 1:100 or 1:200)
* Scale measurement bar to be included
* Scale to be noted on the lease plan
* A 1:1250 scale location map for urban areas
* Full address, with post code and a North point.

Lease plans do not need to be submitted complete with internal layouts however some details related to stairways and other information which aids with orientation should be indicated.

Underground Detection Services

noreply@blogger.com (searchfirst) — Mon, 01 Jun 2009 09:55:00 +0000

Underground detection work goes hand in hand with the other services we provide here at Anglia Land Surveys. Identifying risks and potential hazards is at the core of all GPS survey work and our underground detection services are no different. There are a few other applications however:

* Underground Water Leak Detection
Water leaks under concrete, dirt, landscaping, etc effect the structural integrity of any building work above.
* Underground Utility Location Detection
Before any excavation, drilling or boring work can be performed an underground survey should be performed to prevent causing damage to the utilities and other pipework located underground.
* Underground Electrical Fault Detection
Electrical faults underground can be pinpointed and isolated in order that the problem can be fixed without having to dig up whole sections of road or car park, saving time and money.

For more information on the underground detection services we provide please contact us.

Building Elevations and Surveys

noreply@blogger.com (searchfirst) — Wed, 29 Apr 2009 15:54:00 +0000

At Anglia Land Surveys we are specialists in the production of architectural plans using GPS, total station theodolites, PowerCAD floor plan/elevation software and handheld measuring lasers. The building elevations we produce can then be used as the foundation for any subsequent design, planning, refurbishment or space management work.

* Building Elevations
We've posted drawings from previous elevation work on the building surveys page, showcasing both internal and external elevations of a mansion house that was due to be refurbished. Surveys such as this are carried out using the latest 3d laser scanning equipment and finished drawings can be issued in several formats (AutoCAD dwg, dxf, PDF, hard copy or film copies) and using different units (metres or millimetres).

* Floor Plans
We can provide floor and roof plans for any building; whether it is residential or a large complex premises. All work is performed efficiently and accurately. We aim to complete all building survey work within 10 days from the initial enquiry, but our accreditation to ISO9001 ensures you the peace of mind that quality will not be impacted by this aim.

* Sections
The full architectural detail of a building can be shown in elevation via a section drawing.

GPS Datum

noreply@blogger.com (searchfirst) — Thu, 22 Jan 2009 10:55:00 +0000

At Anglia Land Surveys (ALS) we have been providing our GPS surveying services since 1976 and have grown to become one of the leading surveying companies in East Anglia. Using GPS RTK units we are able to collect huge volumes of data in a relatively fast time and at competitive prices.

GPS Datum is a maths model which represents a portion of the Earth's surface. Lines of latitude and longitude drawn across paper maps can be referenced to a specific map datum. The positional information gathered can then be gathered on a GPS receiver, so long as the map datum selected on the receiver corresponds to the datum listed on the paper version.

One important aspect of GPS datum is in the production of flood risk assessments for submission to the Environment Agency during the planning process. Using datum technology we can overlay level information from the GPS onto existing Ordnance survey mapping, which also allows us to add contours and show the site relative to local flood zones as identified by the Environment Agency.

For more information on GPS datum levelling and the other GPS surveying services please take a look through the rest of the website and don't hesitate to contact us with any questions.

Floor Plans

noreply@blogger.com (searchfirst) — Tue, 06 Jan 2009 10:12:00 +0000

We at Anglia Land Surveys produce high quality measured floor plans using total station theodolites and handheld measuring lasers in conjunction with PowerCAD floor plan/elevation software. By using these methods and instruments we can record every distance, each level and all angular measurements needed.

We have produced floor plans in various different environments, with all our work being risk assessed towards ensuring the safety of our staff and the general public. Previous examples of our work include surveying listed buildings, office blocks, retail department stores, churches, industrial workshops, agricultural buildings, factory plants, construction sites and derelict warehouse buildings.

The floor plans we create are produced in AutoCAD based on data captured from an accurate building footprint as surveyed by our team. This method ensures the finished drawings show an exact representation of the building shape. A floor plan of a multi-layered building will be produced such that it is possible to view each floor separately, and thus view the relationship between the floors.

For more information on the measured floor plans we provide click on the link and have a look at the example roof plan site work over to the left of the page. If you have any further queries please don't hesitate to contact us.

GIS Data Capture

noreply@blogger.com (searchfirst) — Mon, 20 Oct 2008 11:04:00 +0000

A geographic or geographical information system is something which collects data in reference to location. A GIS data capture system such as those we use here does more than simple capture of the raw information as it stores, analyses, manages and presents it too. There are two types of data which can be collected; discrete and continuous and two methods by which both these forms of data can be stored; Raster and Vector. There are pros and cons in using both.

Raster:
* requires more storage space
* records data for all points in the area
* is easier to overlay when compared to vector data.

Vector:
* more easy to maintain and update
* addition of new data to old is possible, whereas raster requires entire new image to take into account new information.
* allows queries related to best method of transportation or best route to reach particular target

Data capture from GIS data can be done in a few different ways. Information already present on paper can be digitized into vector format, or scanned into raster data which can actually undergo a further process to be transformed into vector data. In our case we can enter positions from our GPS survey directly into the GIS data capture system. Once the data is inputted it needs to go through a process of editing in order to remove any possible errors caused by overshoot or undershoot, or even dirt which has caused 2 sections to become connected where no connection exists. It is possible, with GIS data capture, to convert the information stored from raster to vector format.

At Anglia Land Surveys we often process information collected by GPS into a GIS data capture system to produce elevations and images useful in the determination of flood risk assessment or a building survey.

Tree Report BS5837

noreply@blogger.com (searchfirst) — Thu, 16 Oct 2008 13:11:00 +0000

An alternate application of GPS surveys is in the assessment of the impact of a construction to the trees in the vicinity. A tree survey report is performed to ensure that a proposed development doesn't produce a negative impact on the trees. The series of recommendations which is considered to be industry best practice is known as the BS5837, or The British Standard 5837 Trees in Relation to Construction. The standards outlined in this document provide the minimum requirements to be adhered to before a Local Authority will accept a development plan.

We often perform a tree report for our clients in respect to whether a new construction complies with the recommendations in BS5837. The type of details we would include in this survey are the species of tree, it's height whether or not it is a single or multi-stem example, how far into each compass direction the branches extend, the age of the tree and it's physiological condition, and other notes on recommendations for ensuring the future development of the tree and an estimation of the number of years left in it's natural life.

As a result of performing the tree report BS5837 a recommendation could be that protective fencing is erected around an area which contains one or more trees which have been deemed worth retaining. For more information about obtaining one of these tree surveys contact us here at Anglia Land Surveys.

Flood Risk Assessment And PPS25

noreply@blogger.com (searchfirst) — Wed, 15 Oct 2008 11:00:00 +0000

For today's article I'm going to look at flood risk assessment; in particular the PPS25 legislation published in December of 2006. The original policy was actually called PPG25 (Planning Policy Guidance) and was first introduced in 2001. More recently it was updated to become the current standard in flood risk assessment. Now named Planning Policy Statement 25 (PPS25) all new construction work has to be approved by the guidelines it sets out.

You might immediately be drawn to think that the FRA is concerned with the potential of a new construction to be affected by water in the event of flooding, in particular for insurance purposes. This is an important issue, but it is not the sole reason for an assessment. A Flood risk PPS25 also plays a part in the future maintenance of that building too; knowing the potential threats and where they come from gives the owner the necessary information to protect the building over the years.

There is another purpose in the overarching aims and objectives for the flood risk PPS25 assessment. Not only is it concerned with ensuring the longevity and correct insurance of the building being constructed, but also that once the building goes up it won't cause increased the flood risk to the surroundings in which it is being erected. Indeed the policy states that "development should not increase the risk of flooding elsewhere".

At Anglia Land Surveys we use our GPS datum levelling to produce a flood risk assessment which you can use in submitting your planning application to the Environment Agency. Take a look round the rest of our land surveys website for more details about the services we offer.

"... And among the throng that lined along the path he'd followed on and on, he spied a place he named "anon", and surveyed his Kingdom come ..."

An excerpt from "The Travels Of A Broken Man" by Paul Simon. I'm not sure however that Mr Simon was particularly concerned with creating a layered drawing produced in AutoCAD LT2800 to ensure latest compatibility as he was with simply looking at and taking in the land he saw before him. So what does it mean to actually be land surveyors like ourselves?

Some people have made claims that land surveyors are members of the second oldest profession of all time (let's not dwell on what the oldest profession is considered to be). These claims come from evidence to show the first forms of surveying being performed in ancient Egypt and Babylonia. As we have mentioned before on these pages the main objective of surveying land is to measure, quantify and map its area. The applications of this are numerous; from the determination of land boundaries to use in the assessment of risk from flooding or other environmental factors. Indeed without land surveyors such as us it would be impossible for our towns to grow, and for the roads and railways to be created in order link towns and cities without it all collapsing in on itself.

Another important aspect of a land surveyors role is to ensure buildings are being built in a straight line. Despite the level of tourism that can often be created from bad design such as The Leaning Tower Of Pisa, it goes without saying that such things cannot be repeated. I recently was able to see a cinema screening of Man On Wire, a documentary and recreation of Frenchman Philippe Petit's amazing tightrope walk between the two World Trade Centre buildings shortly after they were first erected. Right there you have a prime example of why a land surveyors job is so crucial. We all know what eventually happened to those buildings but in order for them to even be built and to exist for the couple of decades they did they needed to be built under strict measurements which were only possible through surveying the area and the towers as they were going up.

By the way the film was excellent and highly recommended for anyone interested in such things!

If you have any questions about what we do or how we can help you with your building plans then please don't hesitate to contact us.

GPS Surveys

noreply@blogger.com (searchfirst) — Tue, 26 Aug 2008 11:26:00 +0000

GPS (Global Positioning Satellites) allow us the ability to complete surveys in real time without pre and post processing being a necessity. More details of the equipment we use can be found on our GPS Surveys page.

The introduction of satellite equipment to the world of surveying has increased the speed in which we can complete a particular job, although there are limitations, especially if the work is being done in an wooded area. The accuracy with GPS surveys is generally around +/- 20mm whilst we are able to further increase this by observing satellites over a fixed point for a prolonged length of time as this gives us the ability to make certain corrections which would be otherwise impossible.

The main advantage of using GPS surveys as opposed to more traditional methods comes because we no longer need a line of sight to exist between the two points, so we can set everything up and then collect coordinate data across many miles in one day. In some cases we are able to complete the entire site survey in one day.

One of the most useful applications for GPS surveys is in the assessment of flood risk. Any planning process will require an FRA handing in to the Environment Agency; we are able to create an image which sits on existing Ordnance Survey maps and which include routes of safe access and egress.

Measured Building Surveys

noreply@blogger.com (searchfirst) — Thu, 24 Jul 2008 13:54:00 +0000

Building surveys are primarily concerned with producing measured, accurate plans for construction design, building maintenance, repair, refurbishment and restoration purposes. There are several reasons why measured building surveys are required during development work; whether it be to ensure the building is in compliance with regulations or for insurance assessment. The surveys are completed using the latest technology such as theodolites, Leica hand-held disto measuring lasers and on site surveying software.

The results of measured building surveys come in the form of floor plans and cross sections of each floor, which are drawn against an exact footprint of the building previously measured using the same surveying techniques. Drawings are presented in CAD and each floor can be viewed separately or overlayed to show the relationship between floors.

It is also customary to use measured building surveys in order to produce elevations and street scene surveys. We have listed one example of an elevation here; an elevation which was undertaken at the beginning of restoration work. There are other examples of floor plan drawings on the left hand side of our building surveys page.

Topographic Land Surveys

noreply@blogger.com (searchfirst) — Wed, 23 Jul 2008 09:47:00 +0000

Hello and welcome to the blog pages of Anglia Land Surveys. Throughout the coming weeks and months this area will be updated with articles of interest and news all related to the surveying world. This first article will attempt to make topographic land surveys an accessible and interesting subject for those people who are not entirely aware of its role and significance. Wish me luck!

It would be wrong of me to assume that all the visitors to this web site arrive here with a preordained knowledge of our work; of what topographical land survey means, why it is important and what is involved. After all it isn't just experienced developers, engineers or architect firms who are likely to require a site survey. We provide surveys for large developments as well as individual projects.

So what is a topographic land survey then? One definition is that it measures the elevation of points on a particular piece of land, and presents them as contours on a plot. Another definition which may serve to illuminate the point is one which describes a topographic map as being "a detailed and accurate graphic representation of cultural and natural features on the ground" (The Centre for Topographic Information). There is often a common misconception that a map which contains details of relief is thereby defined as topographical map, but this does not fully encompass the range of information presented in a topographic land survey.

Performing a site survey before any development will provide accurate data on the plot dimensions which aids in calculating a purchase price and, equally as important, it tells us what the limitations on development are. Anyone planning to build on a piece of land will be subject to various criteria set out by institutions such as the Highways Agency or the Environment Agency; topographical land surveys give us the ability to ensure we satisfy these criteria. Once the build is complete it is customary to produce a second survey to take into account the new development and in order to relay the new topographical information back to the interested parties, including the Land Registry.

Our finished topographic surveys can be provided on paper, on CD or by email. For more details on these or any of our surveying services please don't hesitate to contact us.
