PRODUCT INFO
PMS Pavement Management Services Ltd. (PMS) is a civil engineering consultancy firm specialising in testing, evaluation and management of roads and airports. The company was founded in 1992, and has offices in Galway and Dublin. PMS is INAB accredited for all of its pavement services
Road Surface Condition Surveys
We own two Dynatest Road Surface Profiler vehicles to simultaneously measure pavement performance parameters at high speed (c. 70-80 km/h). These parameters include Rut Depth, IRI, Geometrics, Surface Texture and Video.
Structural Surveys:
For structural evaluation, we now own three Falling Weight Deflectometers (FWD) for use on roads and airports. PMS now own and operate a high-speed Ground Penetrating Radar (GPR) system. Since PMS has introduced GPR capabilities we have carried out pavement construction surveys for the NRA and a wide range of local authorities.
Skid Resistance (SCRIM) Surveys:
We own and operate two SCRIM machines to cater for the needs of our Irish clients. We are the only commercial operator of a SCRIM machine in Ireland. We provide SCRIM measurement and analysis services to the NRA, PPP firms and Irish local authorities. Asset Inventory Network Surveys: PMS can carry out an inventory of roadside items in order to populate a complete Route Asset Inventory of a given road section. The relevant video or LiDAR data is collected at speeds of up to 115kmh. The data collected is normally referenced to GPS coordinate systems allowing integration to GIS, if required.
Laser Crack Measurement System (LCMS) The Laser Crack Measurement System (LCMS) is a highspeed and high-resolution transverse profiling system. Typically, the LCMS system can capture one road profile every few millimetres (5 mm at 100km/h) by using two laser profilers that acquire the shape of the pavement. Each profile gives full 4-meter width 3D profiles with 1mm resolution allowing for the characterization and the visualisation of high quality images and shape (texture) of the road surface.
Highway Testing Laboratory (HTL)
HTL offers a full suite of laboratory material testing on granular, bituminous and cementitious materials to local authorities, material suppliers and contractors. It also offers a comprehensive on-site testing programme for pavement materials, and has carried out QA/QC programmes for DAA, NRA, local authority project staff and specialised surfacing contractors. Mix design for new and recycled materials have also been carried out for a number of material suppliers.

Why Drop Test Reports are critical when approving Fall Protection Safety Grids for Water & Wastewater Networks.
Attention to safety is critical when selecting steel access solutions which facilitate the safe extraction of equipment from a chamber and ensures the safe movement of the operators while doing so.
Specification for Fall Protection Safety Grids
The required specification for pumping stations, wet wells and valve chambers, is for a hinged, fall protection grid to be provided below the access cover and to be capable of withstanding a 250kg load over the total area of the grid. The lifting effort of the grid shall not exceed 25kg. The relevant standards when specifying fabricated steel, Flush Fit or Above Ground covers are: EN 124-3: and BS 9124 depending on the clear opening. As EN 124 does not refer to safety grids or testing, the Drop Test outlined in BS 9124 provides a comprehensive safeguard against varying standards in production that can occur. Fall protection safety grids are the most important safety feature when specifying access solutions, to protect operators against the risk of injury or death from falls into open chambers.
The Drop Test Explained
This test requires the safety grid to be capable of withstanding a 140kg mass applied over a footprint area of 300mm x 200mm and dropped from a height of 2 meters onto any point of the grid. This simulates (and exceeds) the vertical impact of a human being falling onto the grid, at any point onto an area similar in size to their footprint. Request a Drop Test Report to ensure safety grids comply fully to the requirements of the standard. Please see link for our Drop Test to BS 9124 video clip: The video has been published on YouTube: https://www.youtube.com/watch?v=0c-f31M7GDU
Designed for Safety and Peace of Mind
Additional safety features, such as working platforms will allow operators safe access when there are large openings that require multiple covers. Selecting the correct access & fall protection solutions for water networks can be a daunting challenge with factors such as compliance, operator & public safety, ergonomics and asset security requiring equal consideration. EJ are here to help. We can offer specification guidance for a range of infrastructure access solutions in ductile iron, galvanised steel, or composite material to suit your project requirements.
