1.1 Method and Material of Primary Structure Structure Development
The concept image shows an exposed steel structure with the guest rooms hanging off the side. This helps maximise the room’s views of the surrounding area and creates a central void to be used for circulation. This void will allow for sightline from the 1st floor lobby to the sky through each of the floors and the restaurant on the 8th floor. The main structural element in this image was taken from an earlier image. Repeating the element created the overall structure. In this instance the scale of the ‘structural elements’ would need to be refined and developer into a real structure. Visually the structure bears a resemblance to 4 Pancras Square by Eric Parry Architects. The Vierendeel trusses on the first floor have a similar appearance to the structural element from the concept design. As such this was a consideration for the final building. However as this element repeats throughout the design on all floors it felt like an inappropriate method for the size of the development. The final steel frame was made up of universal columns with Parallel flange channels at the lower levels to give the frame a wider visual appearance.

Initial grid based on structural element with irregular spacing and UBs supported by UCs
Universal Beams (533 x 312) were used to create a wide vertical frame element. However these would need to be supported from behind by primary, load bearing Universal Columns. As such these were changed for 305 x 305 Universal Columns. Parallel Flange Channels (430 x 100) with the run from ground level to the underside of the rooms where the steel frame is visible to create a wider element for visual purposes.

Final grid with regular spacing and UCs with PFCs for visual purposes
Changing to a regular grid allowed for greater flexibility when positioning the various elements on the outside walls of the central circulation space. Two staircases, an elevator and four blocks of rooms connect to the central area, having a regular grid allowed for the a more modular approach to be taken with the rooms, reducing the number of rooms that needed to be designed. The grid size was determined by the development of the rooms and the structure supporting them.
The angle of the grid in relation to the existing structure was determined by the existing entrance through the wall and the area where the sack hoist had been removed resulting in the damaged area. The angle allows for guests to see trough the missing area of wall once they enter the lobby. The grid was then positioned to minimise areas where the structural columns would intersect with the wall. After the grid changed this resulted in the grid being repositioned to reduce such clashes.

Heating + Cooling Underfloor heating applied in some areas of the spa and underfloor heat mats installed in the Guest Rooms. The Atrium is not mechanically heated, the low angle of the winter sun will allow direct sunlight to enter the lobby through the curtain walling. Eastcroft Energy from Waste Facility is located just to the south of the site. The incinerator pipes pressurised hot water across Nottingham. By connecting to the network the hotels hot water needs could be satisfied along with heating requirements for some areas of the hotel.
Ventilation The main atrium is cooled through natural ventilation. Vents below the 7th floor ceiling draw warm air outwards. Cool air enters on the ground floor and through windows in the curtain wall behind the lobby. Rainwater Collection All roofs collect rainwater and feed back to the plant room, this can then be used as grey water and for maintaining the courtyard and rooftop gardens.
Shading Limited windows on the south face prohibit direct sunlight in to the atrium with windows providing ambient light to the area. Areas with curtain walling are on the predominantly on the north and west faces to reduce direct sunlight with the overhanging rooms on the south face providing shading for the lobby.

3.2 Samples and References Secondary Steel Frame
Head track Tek screwed to all studs
Slotted angle (SA1002)
Steel Framing System is used for the walls of the 3 main volumes. The system attaches to the primary steel frame and provides a method to insulated the walls and hold the external aluminium cladding panels and in the case of the lobby/atrium, the timber battens. The guest rooms use a similar framing method.
This form of construction is ideal where movement joints in the external cladding need to be minimized. The base of the system requires vertical support. The base track is fixed to the support member. Studs are then built multiple storeys tall as determined by design.
The use of slotted angles is often advantageous where the SFS is offset from the primary structure frame by a distance which is too great for cleats. Upper floor
Intermediate base/head track Base and head track are fixed back to back to receive studs from above and below. (Typically 300mm above SSL.)
Studs are fixed to each slab edge using cleats with slots to allow for vertical movement in the primary structure. Each lift of studs is capped with a track that provides support for the base track of the next lift of studs.
Studs Continuous past the slab. Stud height, gauge, centres and size according to Metsec bespoke design.
Cleats External finishes
Intermediate floor Zed bars (Z402)
External wall - Ventilated rainscreen Metsec studs, typically at 600mm centres
Cleats can be produced either 3mm or 6mm thick and 130mm or 190mm deep. Slots can be provided to allow the cleat to be used as a deflection cleat. Alternatively, the cleat can be manufactured plain (without slots) to act as a dead load cleat. The projecting cleat leg can vary from 100mm to 300mm in increments of 25mm.
Angle cleats By design. Mechanical anchors to slab edge. Tek screws through slots in cleats to each stud.
40 x 40 x 40 x 2mm zed bars can be provided in 2mm material and 600mm length. Zed bars are commonly used where there is not sufficient bearing at the head or base of the SFS panel.

The return leg of the 3mm cleat can be provided without holes to allow the use of self tapping tek screws or shot fired nails into hot rolled steel. Alternatively, 9mm diameter holes can be provided to allow the cleat to be fixed to concrete with M8 Large Diameter Tapcons (LDTs). The 6mm cleat will always be provided with 9mm holes to allow it to be fixed using either M8 LDTs to concrete, or M8 blind bolts to steel.

Frequently asked questions
Underfloor heating mats are used in all of the hotel guest rooms. The system provides a method of underfloor heating with low floor build-ups. As the guest rooms are individual rooms with exterior space below it provides a way of ensuring floors are not cold and brings an element of luxury to the guest rooms.
Underfloor Heating Mats
110W Floor Build-ups Not sure which layer goes down first or what to put underneath heating mats? The following illustrations show the different layers of materials in the most common underfloor heating installations, from floor base to final floor covering.

• Ideal for energy-efficient properties • Quick and easy to install • 3mm cable for low build height • Pre-spaced heating cable • Lifetime warranty Our ultra-thin high-quality heating mats are ideal for new builds, or well insulated, energy-efficient properties, where a low heat output is sufficient. The 110W mat is very economical over larger areas due to the lower power consumption. This system is particularly suited to Passivhaus and sustainable properties. They are also suitable for projects where a limited power supply is available.
