What are precast concrete installations?

Posted: May 15, 2017 at 2:11 pm


Pre-castAt PCL we offer a variety of groundwork services and within this list, we have precast concrete installations.

In simple terms, precast concrete installations consist of casting concrete into moulds or forms to create structural applications.

These structures include:

  • Foundations
  • Beams
  • Floors
  • Walls

The best way to visually understand what these are is by looking at multi-storey car parks. These are primarily made up of hundreds of precast concrete for almost every component of the structure.

Precast concrete installations are one of the more popular choices when it comes to building structures due to a variety of benefits they bring.

 7 Reasons For Choosing Precast Concrete

1. Insulating

This type of foundation involves thermal Inertia, which allows a more constant temperature both in cold and hot regions through the insulating properties.


Concrete isn’t flammable, compared to wooden structures. Not only is the structure able to be maintained for longer periods, but concrete constructions also prevent the spread of fire from one building to another.

In extreme cases such as blasts and natural catastrophes like earthquakes, tornadoes and floods, the concrete structures are able to remain strong.


The casts can be made into a variety of shapes and sizes, allowing versatility in the structural design. The concrete can also be coloured and produced as different textures depending on the design and requirements.

4.Sustainable & Durable

As precast concrete doesn’t require chemical treatment to protect it against rot damage and insect infestations, this makes the upkeep of the structure far more sustainable compared to wooden beams.

Concrete has the ability to last for years and through effective design, this can increase the longevity of the structures.

Due to concrete being made up of natural raw materials (stones, gravels, sand, cement) from locally available sources, this minimises the impact of the environmental cycle.


Advanced technologies are enabling pre-casting plants to create an improved quality product compared to cast-on-sites.


On-site construction using precast concrete is not only faster but also safer as secure working platforms are quickly established.


Due to the speed of the construction and the expense of the materials, this makes precast concrete installations far more affordable compared to other options.

United Living – Broxtowe Council

Posted: May 15, 2017 at 2:10 pm

Picture1.p2ngSince December 2016 until February this year, Principal Contracting Limited have completed works for United Living on behalf of Broxtowe Council in Beeston.

Principal Contracting Limited were hired to work on a project with the council on their Decent Homes programmes, to modernise and improve their properties due to new housing regulations.

These properties are primarily social sector housing and private sector housing for vulnerable people, making it important for these updates to be sorted to improve the tenant’s quality of life and safety.

The works Principle Contracting carried out included; adapting fire escapes to make them safer and easier to use, as well as creating new footpaths that are wider and with ramps, to allow wheelchair access to the properties.

Since this project, Principal Contracting Limited have won another 12-month contract working with United Living on the Broxtowe Borough Council Decent Homes contract.

Types Of Engineering: Highway Engineering

Posted: March 8, 2016 at 10:42 am

Highway engineering is a branch of civil engineering, which concentrates on the design, construction and maintenance of roads, bridges, and tunnels.

It is an important discipline within the civil engineering industry, which can be traced all the way back to the Roman era, and is constantly evolving to keep up to date with a wide variety of factors.


Factors That Affect Highway Engineering

As mentioned above, there are many things that need to be taken into consideration when looking at the construction of highways, roads, pavements, and other related projects. There are constant increases in the amount of traffic on roads in the UK, evolutions within the cars themselves, and all kinds of pollution to consider. This is all in addition to the constantly evolving highway safety regulations.

Traffic Levels

The first thing a highway engineer needs to consider before starting a project is the current and future traffic volumes, whether that be vehicles on a highway or footfall on a pavement. This will help with the prediction of potential maintenance costs, as well as helping the engineer to decide on materials and design.


In addition to securing financing for the initial project build, ongoing maintenance costs need to be considered and calculated. The technology available, the evolution of highway design, and the economic environment all cause this to be another constantly evolving factor.

Pollution & Environmental Impact

There are several kinds of pollution to be considered when planning any kind of highway engineering project. It’s not just pollution of air and water that are looked at, although they are still scrutinised in detail.

For example, noise pollution. Highway engineers will look at the possible interference with daily life from noise during construction of the project and the subsequent traffic that will frequent the area.

Highway engineers have to consider all of these factors in addition to those that are considered by all civil engineers (such as materials and safety regulations) before even reaching the design phase. We’ll get on to that at a later date, though…


What is Civil Engineering?

Posted: December 8, 2015 at 12:52 pm

Civil engineering is arguably one of the oldest practices in engineering, with even the Great Pyramids being considered by some to be an amazing feat of civil engineering. In short, it is the engineering discipline that covers the design, construction, and maintenance of a ‘built environment’.

What is a built environment?

The term “built environment” refers to any kind of structure or surroundings that are considered to be man-made. Bridges, buildings, roads, canals, airports, dams, tunnels, and parks can all be considered a built environment, and it is the design, construction, and management of these that civil engineers are in charge of.

What does a civil engineer do?

Civil engineering actually covers a wide variety of occupations, so each civil engineer you meet may be responsible for a completely different job or sector.

Just some of the disciplines under the umbrella for civil engineering are:

  • Architectural engineering
  • Environmental engineering
  • Structural engineering
  • Transportation engineering
  • Water resources engineering
  • Construction surveying
  • Construction engineering

This is by no means an exhaustive list, but you can see that there is a wide range of possible directions a civil engineer can take.

Overall though, a typical civil engineer will be in charge of all aspects of a building project. Architectural drawings are created to help civil engineers manage a construction team, and guide them towards completion of the project. They will be present at regular intervals throughout the construction of a project to review the progress, and ensure it will be completed on time and on budget.

What makes a civil engineer different to other construction workers?

Civil Engineers - Principal Contracting LimitedIf you read the above and thought a civil engineer’s job looks like that of a site manager, or surveyor, you’d be half way there. A civil engineer is, in simple terms, a culmination of all jobs within the construction industry. As they need to oversee a project from start to finish, there is so much they need to consider.

Planning a large structure requires an in-depth knowledge of physics, mathematics, geology and hydrology. They must have an understanding of all the site specifications in addition to being aware of the properties of all available construction materials, and the capabilities of all available machinery.

They can then apply this knowledge to the project in hand, taking in to consideration several other factors including cost, safety, and energy efficiency.

9 of Mankind’s Greatest Civil Engineering Feats

Posted: July 16, 2015 at 10:56 am

Civil engineering in some form is one of the oldest professions, with some arguing it is as old as civilisation itself. Without it, we wouldn’t have many basic things that we take for granted today. As the years have gone by and our civilisation has progressed; our understanding of engineering has progressed as well. We are now able to build buildings bigger, stronger, and more efficiently.

Despite this advancement, we can’t ignore some of the incredible civil engineering feats that have occurred throughout the centuries. There will always be a civil engineer willing to push boundaries, and create something unexpected, so we celebrate them here.

Here are nine of mankind’s greatest civil engineering feats.
