STAP Structural Engineering Ltd - Expert Structural Engineers in London, Kent, and Surrounding Regions for Commercial and Residential Projects

Are you looking for a reliable structural engineer in Hertfordshire?

Our structural engineers work closely with our civil engineers here at STAP Structural Engineering. Structural engineers focus on the conditions of how the structure is built for example if a structure is being built in an area that experiences very high winds, then the structure must be able to withstand these conditions. As leading Structural engineers in Hertfordshire, we must consider all the problematic factors and provide technical advice when these projects are being designed.

Being a structural engineer in Hertfordshire and the surrounding areas means that we have the ability to design and discuss all the known and problematic factors that may occur due to its surroundings. Our structural engineer's design roof framing such as beams, joists and rafters, arches, columns and floor framings such as floor decks, girders and beams. Being a structural engineer means that they have a full understanding of materials such as steel, wood, masonry, aluminium or concrete. We have the skills and knowledge to design structures that can resist gravity, high winds, heavy rain, water and collisions. Each of our structural engineers has an in-depth detailed understanding of mathematics and physics, both of which are incredible properties to undertake various design projects and tasks. As structural engineers, we understand the properties of various materials such as tensile strength, density and bending strength, all of which are important factors when designing a structural engineering project. Most importantly, we understand how to calculate different materials' performance under stress, this way the structures can be guaranteed to be safe and reliable. Structural engineers also have the ability to predict how a structure will perform over a long period of time.

As structure engineers in Hertfordshire, we strongly rely on computer-aided design (CAD) systems, this allows for quick and easy modifications to make to the designs and offers our clients the ability to visualise their ideas in 3D. Structural engineering is a subdivide of civil engineering that also includes the application of laws of physics and pragmatic knowledge to the safety of producing man-made structures. Our structural engineers in Hertfordshire have the ability and skill to accurately predict how a structure will perform and how it will deal with stresses and loads.

Our team of structural engineers are fully trained professionals who take full responsibility for ensuring that they design structures that can be used daily, such as bridges and railway stations, it is crucial that they are stage and safe and will not collapse under applied stresses and pressures. Structural engineers have the ability to design different types of structures that are in various shapes and designs that can withstand the stresses of their environment such as storms, bad weather, changing temperatures and gravity.

Our most important aspect of designing any structural project is that we work closely with our clients to understand fully the function of the project, this will guarantee the safety of the structure and the economical solution so that the project is completed successfully. There are a few stages to each structural engineering project, load calculation, structural analysis and then desig

In October 2020, DeconstructUK employed STAP Structural Engineering Services Ltd initially to provide the structural design for a Temporary Façade Retention Design to Rear Elevation for the project ‘Providence Court, Mayfair, London. W1K 6PR’


There were 2 options given in the original design brief for the internal Temporary Works;

  • Option1 – The Steel Supplier’s indictive intention where sacrificial piles need installing.
  • Option2 – A number of permanent piles to be installed instead of sacrificial piles


It was decided that STAP needed to provide a design for bolting steel to an existing slab and the external façade retention on kentledge.


Next, the services requested of STAP were; Temporary Support to the Smoke Vent / Lightwell design, Structural Stability, Floor Load Capacity Structural Analysis Design Check, including drawings and calculations to Approval In Principle (AIP) standard. These AIP documents outline the concept for the design of the structure. Also, design by STAP was;


  • Temporary Support / Restraint to External Wall – Façade Retention
  • Steel Connection Detail
  • Temporary Support / Restraint to Rear External Wall Design
  • Steel Ranking / Splice Connection Detail
  • Temporary Support / Restraint to Front / Side Wall Design
  • Temporary Support / Restraint to Rear External Wall
  • Concrete Footing Timber Shutter / Formwork Detail
  • Temporary Support / Restraint to Party Wall Extension – (Section)

Executing Various Design Checks


Following the designs provided by STAP, they were then required to carry out various Design Checks/CAT 2 Design Checks. A CAT 2 Design Check involves a More Complex or Involved Design and requires a considerable Degree of Interpretation of Loading /Soil Information.


In the months of January through to April 2021, further structural design work was requested from STAP including; Temporary Earth Support Design and Concrete Thrust Block Formwork Design.


Revision to an existing design by STAP was needed when some new circumstances came to light. The original Temporary Façade Retention Design to Rear Elevation needed to be amended to include further support to the additional aspects: Side Boundary Walls & Service Void Wall


The final aspect STAP was instructed to provide on this project was a Floor Slab Load Capacity Design Check where an ZX48U-6 Excavator sits on the slab and is used for demolition.


Throughout STAP’s appointment on this project, they were appointed as ‘Temporary Works’ Co-Ordinators and were required to visit the site weekly for Meetings & Inspection of Temporary Works Installation.

Each structure that is designed has different functionalities, each building will have different standards that need to be met and building codes that need to be met. Each structure must have many aspects that are assessed before the design process takes place. Once we speak to our clients about the main requirements for the structure such as analysing what the structure will be being used for and the loads that the structure will withstand. Our experts will then analyse using engineering software to determine which structure would be best to meet your requirements. Analysing all these aspects will ensure that your design incorporates floor systems, vertical supports, foundations and other parts of the building to make guarantee that the structure is safe and secure.

It is incredibly important that the most important aspect of developing a structure is the safety of the public, if a structure was to collapse the result would be catastrophic, when we develop a design for an infrastructure our expert engineers will factor in all safety measures into the initial designs and will guarantee to factor in all uncertainty into the design whilst also including unexpected problems that may affect the construction process.

As civil engineers in Hertfordshire, we can work with projects from building more floors in an office block or adding a significant expansion to a building or building an entirely new entertainment complex, we also have the skills and knowledge to work alongside clients that have structures that have become damaged from fire, environmental deterioration, wear and tear and corrosion, safety in structure is key. It is crucial that public safety is our top priority and when we are first contacted we will always assess the extensiveness of the damage before moving forward.
