OUR SURVEYS

SCANNER Surveys

 

We operate three SCANNER vehicles in the UK, accredited to the highest standards by Transport Research Laboratory, on behalf of the Department for Transport. Equipped with a range of sophisticated equipment including laser scanners, accelerometers, GPS and cameras, our Tempest SCANNER fleet includes some of the most advanced vehicles in operation capturing road condition data. SCANNER surveys provide an objective 3-dimensional assessment of carriageway condition and the data can be used to produce or back up maintenance schemes, identify areas of further investigation, undertake whole life costing, and develop deterioration models.  

 

“We capture detailed condition data related to the surface and structural condition of your carriageway assets, including carriageway texture, rutting, cracking and profile, with the data fundamental to Single Data List reporting and wider scheme prioritisation and asset management.”           

 

With highly accurate satellite positioning, these vehicles capture precise location information in tandem with a variety of vitally important condition data parameters, which enables the SCANNER data to be matched with other highways data for analysis in Asset Management, Pavement Management or Geographic Information Systems.

 

Our vehicles are also equipped with high-quality forward-facing and pavement imagery, which can be supplied to you via bespoke desktop or web-based software. This imagery provides the contextual backdrop for your highways network, allowing street level and pavement imagery to be viewed alongside mapping and condition data. In turn, this data can be utilised by highways engineers and asset managers for supporting effective decision-making. 

 

 

Visual Surveys

With tighter budgets and even tougher time constraints, getting the right data is essential to empowering engineers and asset managers to make the right maintenance decisions. Visual surveys use engineering principles and nationally-recognised standards to provide vital information on a variety of assets including carriageways, footways, verges and asset inventory. 

 

With over 20 years’ experience in visual surveying, Ginger Lehmann has developed our services over time to ensure we meet our client’s infrastructure inspection requirements. We use an experienced team of UKPMS accredited surveyors and software and our visual surveying services include UKPMS standard and enhanced Coarse Visual Inspections, Detailed Visual Inspections, Footway Network & Maintenance Surveys, Walked Inventory Surveys and LANTRA certified Highways Safety Inspections.  

 

We also conduct bespoke surveys whereby we tailor the survey to your specific data requirements. Recent examples include targeted pothole, patching, flood damage, and car park condition surveys. Indeed, as we operate our own UKPMS accredited collection software NotaVia, our development team are able to customize our data collection software to collect a variety of different defects, features, or assets alongside standard collection methods so we are happy to discuss your exact requirements and are confident we will be able to provide the data you need.  

 

We have a team of highly experienced, UKPMS accredited visual surveyors dedicated to collecting high-quality condition data. Our surveyors operate nationwide to provide safe, timely, and best value assessments of asset condition, utilizing our specialist software NotaVia, and the latest handheld data collection technology, to provide you with the information you need to manage your assets in the most effective manner.

 

“We provide cost-effective inspections of all your assets, ensuring you have the right data for making engineering decisions, prioritising maintenance, and satisfying the general public and other key stakeholders.”

 

We also work at a national level to help improve the collection and analysis of survey data through the different boards we are members and advisors on. Ginger Lehmann are members of the Road Condition Management Group (RCMG), Visual Survey Sub Group and VOCAL Roads Group, acting as technical advisors. This ensures we remain at the forefront of the industry, helping to drive innovation in highways assessment methods.

 

Asset Inventory Surveys

How do you manage your infrastructure assets effectively if you don’t know where, how many, what type, and in what condition they are? This is a fundamental question any asset owner must ask if they wish to follow an asset management strategy or lifecycle planning approach.

 

To support you, we operate high-definition image capture technology for capturing street-level GPS-referenced imagery. This data is in turn utilised for compiling asset inventory datasets and for conducting condition assessments on your critical infrastructure. The geographical position of your assets is recorded with a military-grade Applanix navigation system supported by a high-grade inertial measurement system and differential correction, ensuring the most accurate position is always recorded, whatever the survey environment. 

 

Our multi-camera asset capture vehicle and newly introduced ATLAS quad vehicle enable us to map infrastructure assets across the entire breadth of your highways network covering assets within the carriageway, footways, cycleways and remote sections that would otherwise be inaccessible. Consequently, we can support you in establishing and maintaining an accurate asset register year on year.  

 

“Holding high quality and up-to-date highway asset data is a fundamental building block of any asset management strategy.”

 

Prior to surveying, we will consult with you to define the survey from end to end including the physical extent of the survey, the assets, attributes and condition assessments to be collated, and delivery formats for the video and asset data. The survey is highly customisable, which is critical in enabling you to manage your data needs and budgets as part of a long term asset management strategy.  

 

What can be collected?

We can collect in excess of 50 different asset types, categorised as point, linear or polygonal items, alongside core attribute and visible condition information. In order to provide some guidance on the types of asset collected, many of which are required for Whole of Government Account submissions, popular assets include:

Gullies

Signs

Bollards

Pedestrian

Guard Rail

Safety Fence

Lighting points

Carriageway

Footway

Verge

Traffic Calming

Street Furniture

Grit Bins

Central Islands

Central Reserve 

Kerb

Road Markings

 
 

Skid resistance surveys

Skid resistance surveys are a vitally important part of improving the safety on your road network and Ginger Lehmann can provide skid resistance surveys using accredited survey vehicles. We will work with you proactively to advise the best survey method to fit with your skid policy and our team of GIS technicians are also on hand post-survey to help you get the most from your skid resistance data, helping you understand where to target further investigation and maintenance. 

 

Skid resistance surveys are conducted using a bespoke vehicle, which is based upon a lorry chassis with a large water holding tank similar in size to a "gully emptier." The machine has mounted in its mid-section left side wheel track, a test wheel that is set at 20° to forward travel. This creates pressure on the wheel related to the skid resistance of the road surface and this pressure can be measured and is processed to give figures that represent the road surface skid resistance. Survey vehicles are manufactured to be compliant with the current British Standard BS 7941-1:2006. 

 

 “With high-quality skid resistance data, we can help make your roads safer for all road users, which is the primary objective.”

 

Surveys are usually conducted at 50 km/h but for trunk road or high-speed road surveys, a testing speed of 80 km/h is permissible with speed correction conducted during processing. This ensures high-quality skid resistance data can be collected in a safe and cost-effective manner across your entire highways network. 

 

Once data is made available, additional analysis is possible to compare recorded skid resistance values with locally defined investigatory levels whereby any deficient sites can be investigated on-site as part of a robust and safe skid policy. 

 

In addition to skid resistance surveys, we can also supply GripTester surveys for less accessible sites and Pendulum testing for assessment of footway skid resistance.
