Design Engineers are expected not just to design for the structural integrity of the building but also to consider the buildability of the structures with regard to health, safety and welfare of everybody in the influence of the structures. This consideration should be done prior to construction work, during construction, while the structure is undergoing maintenance and at normal operation time. Health, safety, and welfare also continue throughout the lifespan of the said structure, that is during the structure removal after its design life. Heath and safety works act 1974 put the onus on all duty holders to eliminate risks as much as is possible. In meeting his health and safety responsibility, an engineer is tasks with adopting the principle

One of my alteration work projects required the need for steel works. I had designed a 9metre long steel to support existing partition wall above. In order to limit the lifting weight, I had to design a bolted splice connection; this was located close to the point of contraflexture. This provided ease handling of the material and made installation simpler. My main aim was to reduce the risk of injury due to lifting and reduce the consequence if things ever go wrong. I prepared a suggestive method statement for the lifting operation and advice on the weight of the 762x267x147kg/m to be 371 Kg (2.4m) and 1019 Kg (6.6m long), this is to ensure that competent personnel and equipment are employed in carrying out the lifting work. As the lifting was carried out under a limited space I instructed that the contractor may propose an alternative method of lifting before work could be carried out, if they have a different way of carrying out the work safely. The contractor was requested to supply the capacity of the lifting equipment’s that will be used. I also insisted that adequate lifting chain should be installed to ensure that the beams are stable during the lifting process. I was also concerned that there might be the possibility of working under the suspended beam. I, therefore, instructed the contractor to avoid working under the beam while it was being suspended. I requested that the lifting equipment should be subjected to a factor of safety of 2 -this is to build against all types of failure. I insisted that all equipment should be inspected before use to eliminate failure as a result of the equipment wear and tear, fracture and
