Major Building Works

Major Building Works is the coordinating the delivery of a combination of complex services provided by a contractor to maintain, refurbish and repair the exterior of any building, and in so doing protect the asset value. When considering Major Work to be carried out on the exterior of a building it is important, indeed vital, that the contractor possesses the necessary multi-discipline skills, experience and expertise and credentials to carry out the required work efficiently and cost effectively.

We have the inhouse specialisms and experience that can tackle any issue. When we are called to complete a Major Building Works project, we work in specialist teams on a project to address all issues in one go. No matter the substrate or specification, our team is agile and capable in completing the project to the highest standards.

Our Major Building Works Service

If it’s the exterior of a building that needs major works refurbishment, we have got the inhouse specialisms and experience that can tackle any issue. For a number of clients, every five years we move in several teams to address all issues in one go. We coordinate who goes in and when for best efficiency, saving time and budget. All major works are always conducted under the direction of a building surveyor who ensures the work is specified and completed correctly. Our refurbishment experience for clients is centred in conurbations and recent projects have been mainly in London, and within the M25 and in Bournemouth.

Tailored Services

When assessing any Major Building works there is not, a standard formula as the state of any building differs one to the next and the refurbishment requirements are determined by the survey and so the services offered are bespoke.

We work closely with a surveyor, jointly assessing the requirements, methodology and processes from which a scope of works is agreed with the client, to deliver a major works service that is cost effective and exceeds the client’s expectations. To assist the Surveyor, we equip our Technicians with camera helmets with a link to a screen at ground level, such that by using rope access and radio contact between the operative and the surveyor, detailed inspection and survey can be conducted efficiently.

Cost Saving

As our Technicians are IRATA Certified combined with our patented equipment we can carry out specialised services on any height of building without the need for scaffolding.

Eliminating the need for scaffolding saves tens of thousands of Pounds and saves time on any project.

In addition, it minimises disruption to both building occupants and the surrounding community, in fact in certain building locations scaffolding would be impossible either because of busy thorough fares or proximity to other buildings.

We undertake continual training for our operatives with special emphasis on safety issues which is always at the heart of our Staff Development programme.

Creating Confidence With The Right People For Every Project

A JCT contract is always used by Spectrum to plan the project for approval. This contract requires an organisation to create the most appropriate contract following industry specifications. These contracts are highly standardised according to specific type of work and require detailed knowledge of the standards and specifications.

What Are Major Building Works?

Major building works are the coordinated delivery of a combination of a complex set of services by a contractor to repair and refurbish the exterior of any building.

When Do You Need To Carry Out Major Works on your Building?

You need to act when you can see damage, before it accumulates and leads to greater and more costly problems. Cleaning the exterior surface of bird excrement, fungal build up and so on are all visible problems. Similarly, broken gutters or stonework. There are also other problems which are often out of sight and don’t reveal their impact on the structure of your building until they start to cause major issues. Taking a defensive approach and regularly planning in surveys and assessment is the key to long-term maintenance, ensuring that the building exterior condition is assessed and, if necessary, fixed at an early stage.

What Do Major Buildings Works Projects Include?

External Redecoration:

Whether your property requires repairs or redecorating, our team has experience in restoring the face of any building!

Timber Works:

Wood being a natural material it is subject to seasonal climate conditions. In Winter or in periods of high humidity wood absorbs moisture and expands, whereas in Summer or dry conditions it will contract, which produces constant flexing. This causes problems when wood is used for window frames as in Winter opening a window can be difficult as it is stiff.

Flexing, according to climatic conditions, causes the putty, that is used to retain the glass in the frame, to harden and even come away from the wood or glass which leads to gaps and hence draughts from the windows! Further the constant flexing causes the paint coating on the wood to crack and lift exposing the wood below which ultimately leads to rot meaning unless noted and remedial work undertaken an expensive window frame replacement.

Insects can also have a detrimental effect on timber penetrating the surface to feed on the natural sap within the wood which allowing mould spores or algae to penetrate and accelerate deterioration. Timely intervention via regular inspection will save money!

Metal Works:

Metal requires special care as it can oxidize over time, especially if your property is located in a costal area. Through our Metal Works services, our team applies specialist techniques to restore rusted and oxidised rust to its former aesthetic.

Stone Work:

As experienced operators of both DOFF and TORC equipment our Technicians can restore stonework, regardless, of age, to its former pristine state

In addition, extensive training for our Technicians means we can carry out stone repair work to the highest standard matching any repair to the original state, so it is seamless and undetectable.
