The engineer starts with a broad understanding of the loads on individual elements and narrows the focus until each element and ultimately the entire structure is designed to safely transfer all loads, meet code requirements and provide an acceptable solution that can be signed and sealed. The engineer will look at the various types of units on a larger multifamily project or the variety of room uses in a larger single family home or commercial structure to have an idea of the various uses of a structure. If the structure has multiple levels, the engineer will note if interior walls fall on top of each other, commonly referred to as ‘stacking’, to efficiently transfer loads between levels. The stated reason in the RPS design log for this item was “to clarify assumptions and intent”. Working from the top down, engineers will produce initial designs first for the roof system. The decorative wave-form cladding panels affixed to the wall cladding panels to the east and part north and south elevations (item 8 of the Scott schedule). Requirements of soil improvements if any 5. Once an initial conceptual design is complete, an engineer will turn their attention to system design in a top down manner. It is a common occurrence in construction disputes for a party, generally the Employer, to allege that a building does not meet its intended design life. Further in the construction process, the engineer is often called upon to review RFI and deferred submittals, obtain code approvals or prepare construction schedules. Through this process the load paths are accurate, specific and reliable. This analysis software will allow the engineer to apply a variety of loads including dead, live, wind and seismic. A key document relied upon by Blackpool was the Functional Procurement Specification (a contract document). Within the context of the built environment, the term ‘ structure ’ refers to anything that is constructed or built from interrelated parts with a fixed location on the ground. Since earthquakes release energy that pushes on a building from one direction, the strategy is to have the building push the opposite way. To design an earthquake-proof building, engineers need to reinforce the structure and counteract an earthquake’s forces. The EOR will determine site specific requirements for the structure that are dependent on its location. To aid in this analysis, engineers will use specific software applications geared towards structural design such as SAP 2000, STAAD and/or RAM. © Truss Publications, Inc. All rights reserved. Bearing capacity of the soil 2. The Court said if they did not, the words “external shell” would not have any sensible meaning (which could not be correct). As such, the Court held that the design life for the cold formed components was 25 years. Think of this as repetitive in nature working toward the ultimate goal of an efficient design that meets the variety of requirements the structure’s configuration places on the path that the applied load will need to take to get to the ground.

Blackpool argued: “…in the case of a portal frame structure the building structure comprises three essential elements, namely the primary steel structure, the secondary steel structure and the external walls and roof, so that all are within the definition … (a) the term building structure naturally includes all load bearing or load transmitting elements of the depot building; (b) the cold formed components and the roof components are secondary structural elements within the building; (c) the wall cladding panels and cantilever soffits form part of the walls and the roof and, thus, form part of the building structure because: (i) as such, they are part of the overall structure of the building; and (ii) the walls and the roof transmit wind and other loads which bear on them as external structures.”1. Volker’s position was that the contractual design life of the wall cladding panels was 25 years and the contractual design life for the cold formed steel components, roof steel components and other components was 20 years (e.g. The foundation design guide discussed earlier includes in detail the design procedure for isolated column footing. The element engineering phase begins with the engineer ensuring accurate dimensions for the various portions of the construction project through geometry coordination as defined in 2D or 3D CAD software. Volker argued that if there was any ambiguity, the RPS design log responded in its favour because it was not inconsistent with the terms of the employer’s Works Information or the Functional Procurement Specification (which Blackpool relied on). It is headed ‘minimum design life’. The Court’s view was that “external shell” as used in the RPS design log included the wall cladding panels and the external aluminium roof trays. Buildings designed under the IBC, exceeding certain provisions of the IRC or exceeding legal exemption requirements will employ the use of an EOR. Design life and meaning of building structure. Maximum load capacity of the soil 3. Structural engineers are typically brought into a project by the architect/building designer and work on behalf of the project owner and remain engaged throughout the construction of a structure to review and accept deferred submittals and RFIs (request for information) for conformance with the structural plans and specifications, monitor construction and perform special inspections as defined on the permit or as contracted to undertake. 24 building structure design Lord Neuberger at paras will only focus on these aspects of RPS.
