Highway Civil Engineering was sub contracted to his project at a last minute after the contractor failed to meet their obligation. It was a very intricate project and one we had to approach with all our focus. The target for us was come up with safe walking routes for pedestrians. We started by installing a chain linked guide rail and then upgraded the traffic islands.
Highway Civil Engineering set majority of the posts inside existing road construction materials, either concrete or tarmac. The posts were saw cut and broken out, all this was done before the post holes could be excavated. We then bored the post holes where the ground was less compact. The post hole borer can drill a clean hole but is only effective in soil or stone. In excavating the rest of the other holes, we used a small hydraulic breaker. Drop down bollards were installed at access points.
Furthermore, Highway Civil Engineering extended an existing island and altered to prevent traffic parking near footways. The excavation of the island was done to formation level and compacted. We then installed Geo textile membrane to minimise weed growth. Grading of chippings was done to the inside of the island providing a clean finish.
Highway Civil Engineering went on to install post sleeves in a concrete surround inside the upgraded traffic island. These then eventually carry a lit entrance sign. We then installed guide rail posts either side of the new footway. In finishing off, Highway Civil Engineering fitted timber edging board to the sides of the path and we then graded the stone to tarmac formation level and finally we laid a wearing course tarmac to the paths and the guide rails installed.
It was amazing to look back at the completed project and all thanks to our project managers and supervisors for finishing the project in a timely manner despite being offered the project at a very short notice.
Standard Health and Safety Procedures
These procedures are to be followed by all Drivers and Supervisory Staff responsible for organising work.
These procedures are to be read in conjunction with relevant Risk Assessments
Personnel Consideration: –
Drivers must be competent and have attained a CPCS Plant Operators card.
Excavators should be accompanied by a Banksman, particularly when buried services are
anticipated. Drivers and operatives must wear reflective clothing and appropriate Personal Protective Equipment.
Equipment Requirements: –
Excavators shall be selected to ensure that they are working within their limitation and are fit for
the intended task.
Excavators shall be fitted with flashing beacons.
Personal Protective Equipment will include safety helmets, ear defenders, reflective clothing and safety boots.
If working on a public road or highway ensure that the machine is insured and complies with road traffic regulations.
Material Requirements: –
When loading excavated materials, care must be taken to ensure sufficient safe clear working space is available on the far side of the vehicle being loaded, to prevent injury or damage to passing personnel or vehicles from falling debris.
Environmental Considerations: –
Ensure adequate ventilation around excavator to prevent build of poisonous exhaust fumes.
If using impact power hammers, it will be necessary to screen off the workplace to reduce nuisance levels and flying debris to neighbouring properties etc.
Detailed Procedure: –
Ensure the presence of underground services is known and the driver advised of their presents
and location. Location by hand dug trail holes is essential prior to commencement of mechanical excavation.
Mark all overhead services with suitable temporary warning structures (poles and bunting, scaffolding etc.) and inform driver of their size and nature.
Ensure when excavating that bucket does not get within 5m of overhead electricity cables.
Wear Personal Protective Equipment.
Use of a Banksman to assist in the careful locating and supporting of underground services.
When loading excavators from trailers ensure it is carried out on level ground and ramps are long enough and strong enough to allow a safe angle of descent. Tracked excavators should be unloaded onto sleepers to prevent damage to metalled road surfaces.
Secure workplace from unauthorised access by members of the public or vehicular traffic by installing protective barriers or suitable traffic management.
Make sure trenches are suitably shored and suitable working space is available to prevent excavators from getting too close to trench sides.
Use buffer stops to prevent machinery from getting too close to the edge of the excavation.
Do not allow unauthorised use of the excavator. When not in use, park up safely with bucket
and/or backactor on the ground, remove ignition key and lock vehicle.
Do not travel alongside or park adjacent to trenches when men are working in them.
Avoid turning on slopes to reduce the risk of overturning.
Do not carry passengers on any part of the excavator.
Do not use the bucket as a makeshift work platform.
Do not use the excavator as a crane.
Avoid jumping down from the excavator; climb down using access steps provided and using the three point of contact system.
Do not force the excavator to do more than it is capable of. This can cause it to become unstable.
