Line item selection based on price and planning

Quite often we identify project cost overruns which stem from a single planning decision where one item is selected purely on upfront purchase price, without considering the wider installation, integration, maintenance, and risk implications it creates across the project. In many sectors we work within, a product may appear cost effective as a line item, but ultimately drives significant additional costs once structural changes, (in this case flashing complexity), weatherproofing requirements, labour, access, remediation, and operational disruption aspects are factored in. These seemingly minor specification decisions can influence almost every downstream trade and frequently become the source of major overruns.

A good example within the skylight sector is the use of centre pivot skylight on a flat roof where the unit is orientated the wrong way relative to the roof fall. While the skylight itself may initially appear cheaper to purchase, the installation outcome can become extremely expensive and technically difficult. In this case, the design created a wide vertical wall requiring extensive flashing and back-tray detailing, curved upstands, additional internal framing work, and complicated weatherproofing measures. The situation is further compounded in a tenanted dwelling when the skylights remain open during occupancy, increasing weather tightness risks and disruption to occupants. What initially appeared to be a saving on a single line item ultimately resulted in a far more costly installation and repair process for the owner.
