We write often about developments to our services and all things ‘Surveying’.
We are surveying a couple of manholes which have been discovered by Hall Construction on their site at Teeside.
They required the invert level, the size of the main culvert and generally the overall stability of the shaft.
@jonnysayer and @thomasbewell were our
' survaders ' on site to get the job completed.

Favourite thing about work : A varied workload, everyday is different, we visit some interesting places.
Hobbies : Jack enjoys the outdoors life, shooting and showing his beloved sheep.
Jack is a key member of the @tritechsurveys team and our resident drone pilot. He is an expert when it comes to #uav flights, from carrying them out on site to processing and completing the 3D inspection models for our clients.
He has not quite mastered the MiG -28 just yet !! 😁

There was definitely light at the end of the tunnel for the @tritechsurveys team on this job, but on closer inspection it was only Gary in his waders with the Trimble X7.
Job well done at the Culvert. 🙂

In December 2022, @theatlanticgrappler will set off as part on the Talisker Whiskey Atlantic Challenge to row solo 3000 nautical miles across the Atlantic to Antigua.
He will battle with sleep deprivation, salt sores and the physical extremes inflicted by the race, left alone with the job of getting the boat and himself safely to the other side. He is aiming to raise over £70000 for the Paediatric Intensive Care unit at Leeds General Infirmary, the unit that saved his sons life.
@tritechsurveys and @sitesurveyingservices have become an official sponsor to support Mike with his awesome challenge and help to get the Atlantic campaign to Antigua saving the lives of many children along the way.
We will be posting about Mike's progress in the build up to the race and following his preparation closely.
You can still donate to this great cause by following this link -

A selection of photos from a series of tricky culvert inspections recently completed for a client using the Elios 2 mounted to a 3D printed RC airboat that was made in-house.
Silt levels within the culverts prevented us using a conventional boat with a hull so the above was brought to life to combat this.
You can find futher details and videos of this on our LinkedIn page.

@tritechsurveys out this week on nightshifts surveying dual carriageway and roundabouts using the Mala Mira HDR GPR. All went smoothly and some serious ground covered. So much faster and more importantly safer than doing this traditionally with trolleys.

What we do
our services
Land and Engineering Surveyors
measured building surveys
From an Industrial Unit through to a Historic House to a Semi Detached House, Tri-Tech can provide a measured building survey for all.
river surveys
setting out & site engineering
Bread and butter work for us! Having a strong relationship with many civil engineering companies we have a very strong team of Site Engineers and Engineering Surveyors working for us.
control network installation
At Tri-Tech we have vast experience in this field. Be it a large highway scheme or a private property we can advise on what accuracies are required from your control network depending on what work you are carrying out and the tolerances you are carrying this work out to.
uav mapping & aerial surveys
Large areas of ground can be covered capturing the most unbelievable detail which would just be unable to be recorded with traditional methods. Our clients have really seen the benefit of what UAV surveys bring to the table.
survey equipment hire
Being a leader in the Surveying and Engineering sector we have a fleet of modern survey equipment at our disposal which is second to none. We carry the latest GNSS Base Stations, GNSS Rovers, Robotic Total Stations, Laser Scanners, Digital Levels, and Dual Grade Lasers.
3d machine control
Machine control systems have been around for years now and Tri-tech have been utilising these systems from the very start. We realised the benefits of these systems early on when working with earthworks contractors.
volumetric analysis
We specialise in the analysis of a scheme’s volumetrics at any point in time. Be it Tender, Prestart, Monthly, Weekly, or Final.
laser scanning
For mass collection of accurate survey data then nothing beats scanning. Using 3D laser Scanners the surveyors can capture millions of points per second with the creation of a PointCloud.
utility mapping
Using the latest equipment, we can provide the location of underground services in either 2D or 3D. We use state of the art Ground Penetrating Radar and Electromagnetic Location to assist your project when service avoidance may be a potential issue on site.
monitoring
Is there any movement? That is the question that is asked before and during any monitoring scheme. That is the reason we undertake monitoring, to check for movement.
topographical surveys
Tri-Tech work for a variety of different clients on different projects, and we pride ourselves on delivering accurate, efficient, cost effective surveys ensuring our clients receive the best possible product.
our clients say?
We have formed very close relationships with a superb selection of high profile and loyal clients which use our services. Take a look…

I’m a strong believer of giving praise where praise is due. Tri-Tech have provided an excellent service, easy to talk to with a professional and knowledgeable attitude. The attitude to Health and Safety, knowledge and non-stop working was absolutely brilliant. They went over and beyond, especially when they very kindly stayed on site to enable me to finish a few things, so I wasn’t lone working. I will be feeding back this positive feedback to the Kier team as well.

I’d just like to say a massive ‘thank you’ for all your efforts in getting this package of work over the line, I know it hasn’t been the most straight forward! We are grateful for your willingness to go the extra mile to ensure the job was completed. I don’t know many contractors (if any) that would go out there way to build a custom boat! Always punctual and professional on site. We have found it a pleasure (and an education) to work with Tri-Tech. Deliverables were to a high standard, especially the models which has allowed us to have a better understanding of the structures vs just photos and videos.
