Developed Design Continued

Developed Design stage name can be misleading, its old name was more informative Design Development. DesignBuildings.co.uk have provided a clear description of the stage as well as detailed list of works that should be completed within this stage.

This stage should include...

''Overall layout. Road layouts and landscape. Operational flows and departmental operational policies. Horizontal and vertical circulation routes, including accessibility requirements. Schedules of accommodation, including occupancy numbers for each space. Identification of standard and non-standard room layouts. If appropriate, room data sheets. Building dimensions and gridlines.

Architectural plans, sections, elevations of buildings. Block plans. Site plans and external works. Changes in floor levels. Expansion joints. Demarcation of changes to finishes. Reflected ceiling plans.Outline specification including schedules of components, defining the performance and/or material standards required (including colours).

Elements of design that require specialist input or early choice of manufacturer. Designers should investigate suppliers certificates, warranties and compliance with standards.

Requirements for mock-ups, testing, samples or models necessary to satisfy performance or public relations requirements (including computer generated images).

Key assemblies, component drawings and schedules with special attention to junctions and interfaces between elements which will influence the structural or services designs or have an effect on the spatial allowances. Key details will include ( external walls lining, cladding and gazing. Windows and blinds, balconies, entrances, roofing, drainage, gutters and outlets. Floor constructions, staircases, DPC and services plans. Power supplies and fire related cables.

Load bearing internal walls and partitions, including lifts and other shafts.

Initial schedules indicating: Finishes, Doors and ironmongery, Sanitary fittings, Room numbers and signage.

Structural plans sections, elevations and specifications:

Building services plans, sections and elevations showing: Plumbing and drainage (high and low level). Ductwork. Heavy pipe work. Electrical trunking. Light pipe work. Electrical control wiring. Radiators. Plant room layouts. Riser drawings. Access requirements and builders work in connection.

Define phases if the project is to be phased. This can be complicated by items that appear in buildings intended for later phases, but that are required for the operation of earlier phases, for example boilers or escape stairs. Safety strategy.

Fire strategy, including: Zoning and compartmentation. Separation (such as fire resistance of compartments, restriction of openings between compartments and distances to boundaries). Protected shafts (staircases and services). Surface spread of flame and escape strategy (including travel distances and staircase widths). Active measures such as detection, ventilation, alarms, sprinklers. Minimum ventilation requirements where no mechanical ventilation is provided. Dry risers and hose reels. Uninterrupted power supplies. Fire rated cables

Acoustic separation and acoustic conditions (reverberation times etc).

The use of materials and the potential for re-use, recycling and waste handling (see site waste management plan).

Detailed cost plan showing the capital and lifecycle costs for all the components.

Risk assessment including operational issues such as; lifts (goods / passenger / fire and other equipment that may require a lifting certificate and cleaning cradles), cleaning of atrium roofs and facade etc.''
