Construction Design Partnership

Consulting Structural Engineers for over 40 years.

The practice of A.K.Hill and Associates was founded in 1976 and became Construction DesignPartnership in 1988. The practice specialises in Structural, Civil and for the last 25 years,  Facade Engineering.

Here To Help

We like to share the knowledge we have built up internationally over the last 40 years, from the very beginning to the culmination of the project. Among other things, we cover the five stages of structural design:

Conceptual Design

initial design of the building elements (e.g. slabs, beams, columns …etc.) is performed based on code recommendations

Elemental Determination

After finishing the initial design, the exact dimensions of each building element shall be determined. First, an analysis model is created

Iterative Design

Now you have the straining actions on the elements based on the initial sizing, you can use them to design according to code.

Foundation Design

After the final dimensions of members are found, the foundation system type can be selected taking soil conditions into consideration


In this step, the structural plans are created. These plans are fully detailed so the construction process on site can proceed smoothly

Why don’t you charge for Consultation?

The difference between a Site Visit and a short Telephonic Consultation for advice is cost. We sometimes find that our clients don’t actually need a Structural Engineer, and any ethically-run company would not charge for advising in this way. It also does not require a site visit in many cases where a simple phone call can suffice. Schedule your call today.

Easy Consultations

Zero Jargon

 Planning for Safety

When you contract a qualified consulting structural engineer to handle your project, you engage in a relationship unlike any other. What is happening is that you are potentially entrusting your future safety and the safety of your children, friends, acquaintances in the hands of a complete stranger or team of strangers. It is not always enough to be qualified, experience plays a massive role too. We address this by drawing on the wealth of experience we have built up since 1976, are happy to share our stories and at the end of your project, leave site as strangers no more. A CDP designed structure is a safe one, we promise.

What does a Structural Engineer do?

Structural engineering is a branch of civil engineering, and its applications are diverse. A great deal of what structural engineers do involves designing structures such as buildings, bridges, tunnels, etc. The majority of structural engineers work primarily as consultants to architects or design-build contractors.

What kind of education do you need to become a Structural Engineer?

You’ll normally need a degree or postgraduate qualification in structural or civil engineering. You may also be able to get started with a degree in a related subject, such as construction, the built environment or maths, but it may take you longer to qualify.

Why do I need a Structural Engineer?

When carrying out renovations. You may need a structural engineer when making changes to your home that could affect the stability of your property. Essentially, any project that alters the structure of the building or requires building control approval will require the expertise of a structural engineer.

Do Structural Engineers design buildings?

More experienced engineers may be responsible for the structural design and integrity of an entire system, such as a buildingStructural engineers often specialise in particular types of structures, such as buildings, bridges, pipelines, industrial, tunnels, vehicles, ships, aircraft and spacecraft.
