INTRODUCTION AND BACKGORUND

INTRODUCTION AND BACKGROUND

New North Zealand Hospital (The Client, NHN) carried out a project competition in which seven companies submitted tenders on the new future hospital in Hillerød, Denmark. In August 2013, the assessment panel selected three winners of the project competition who subsequently participated in a negotiated procedure for a lead consultancy contract, which was ultimately awarded to “HdeM VLa partnership Nyt Hospital Nordsjælland I/S” (The Total Consultant, TC). Ever since then the TC have been developing the design of project. Details about the project can be found on the website: https://www.regionh.dk/nythospitalnordsjaelland/english/Sider/default.aspx

At present we are in the Project Proposal phase “Projektforslag” which is expected to last until the end of 2016. There is an aspiration of introducing prefabricated elements in the building and the TC now wishes to further explore the degree of prefabrication that could be accomplished by obtaining feedback from manufacturers/suppliers. For this reason we wish to enter into a Technical Dialog with manufacturers/suppliers in order to take advantage of the knowledge and expertise in the market. This dialog is not meant to be a prequalifi cation process or any form of tendering to award a contract for the construction of the project, however it could be expected that the recipient of this document is approached in the near future by the Client to participate in the tendering procedure for the construction works.

For this Technical Dialog we have selected the following companies based on their experiences and capabilities in the prefabrication fi eld, but by no means is a defi nitive selection; hence the Client might increase or modifi ed this list at its convenience in due course.

ADK Modularum Gmbh Forta Medical Jytas A/S Kodumaja A/S Scandi Byg A/S Portakabin We would like to frame this consultation in a series of meetings and visits to your factories within the next 2 months (8 weeks). The TC have assembled this document to facilitate the discussions on which to base the Technical Dialog and which is an extract of the deliverables included in the Outline Proposal “Dispoaitionsforslag” submitted and approved by NHN in May 2016. It is not expected to share more material relevant to the project during the Technical Dialog; however the members of the TC to be part of the meetings will be more than happy to address any questions that you might have and that are necessary to conduct the meetings. These meeting are planned to be in English. Although the primary goal of this dialog is exchanging on the technical aspects of the prefabrication the discussions could evolve around the time and cost constraints of the project.

The following is the suggested timetable

OVERVIEW

The principle to build the bedward levels consists of a combination between “modules”, manufactured off site and thereafter delivered and installed on site and “prefabricated panels” which span across the modules to fi ll up the “in-between” spaces. The range of module sizes goes from Patient Room Units to Bathroom Pods. Once the modules are delivered and installed the external elements of the building skin such as the balconies and roof fi nishing will be installed.

Even though the fi nal degree of prefabrication will be explored more in detail during the Project Proposal phase, the minimum expected would be the Bathroom Pods. These are common practice by contractors, offers immense benefi ts in terms of quality control and the elimination of several trades working simultaniously on this part of a site.

While the original design at the competition assumed a formal expression of prefabricated modules at the bedward levels, the current design does not intend to keep this approach. Therefore the level of prefabrication has to be seen purely as a mean and method of construction whose fi nal decision is driven by cost and time parameters.

DETAILS OF PERFORMANCE CRITERIA - STRUCTURE

STRUCTURE - DETAILS OF PERFORMANCE CRITERIA

a. The design and construction of the building is proposed to be undertaken in accordance with Building Regulations 2015

(BR15) published by the Danish Ministry of Economic and Business Affairs and the Danish Enterprise and Construction

Authority

b. The design and construction of the bed ward structures are to be undertaken in accordance with the Danish Standards

including their accompanying Danish National Annexes and all relevant Parts of each standard.

c. The indicative design working life for the building is proposed to be 50 years in accordance with Design Working Life Cat-

egory 4 from Table 2.1 of DS/EN 1990.

d. The main hospital building is classifi ed as Consequence Class 3 (CC3 - High Consequence Class); this classifi cation is

based on Table B1 DK NA of DS/EN 1990 DK NA:2013. The design and construction of the bed ward structures should be

taken as being classifi ed as Consequence Class 3. Documentation of Robustness will be developed for the building at a

future stage of design development.

e. The bed ward structures are to be constructed in accordance with Execution Class 3 (EXC3) as defi ned in the relevant Dan-

ish Standard for the proposed structural materials.

f. The structure is to be designed and constructed to limit defl ections and movement to avoid the unsatisfactory functioning

of the structure under normal use, to avoid discomfort to the building users and to avoid damage to the structure that could

impact on the appearance of the construction works in relation to structural movement. Specifi c limits in relation to movement

and defl ection will be developed for the building at a future stage of design development.

g. 60 minute fi re resistance to the bed ward structures is required up to level 3 in all areas of the building and 0 minutes fi re

resistance is required for the roof structure.

h. The building structure is to be designed and constructed to resist the following actions in accordance with DS/EN 1991:

• Self-weight and permanent actions

• Variable (imposed) actions including Wind actions and Snow loading

• Actions during execution

• Accidental actions

• Thermal actions

The building loads have been categorised and assessed using the criteria defi ned in DS/EN 1991 and are described in more

detail below NB all load stated are unfactored. The building will be designed to resist combinations of permanent and vari-

able and accidental actions in accordance with the requirements of DS/EN 1990.

• Variable Area Load (qk) to fl oor structures = 3.00kN/m2

• Variable Point Load (Qk) to fl oor structures = 3.00kN NB this value includes load allowances for patient hoists that

are required to be suspended to the soffi ts of the structures in all patient bed rooms. An increased load allowance

of 5.00kN is required in the bariatric patient rooms (locations to be confi rmed)

• Super-imposed permanent load (Gk) = 1.00kN/m2 allowance for ceilings and services and 2.00kN/m2 allowance

for screeds.

• Variable Area Load (qk) to roof structures = 1.50kN/m2

• Variable Point Load (Qk) to roof structures = 3.00kN NB this value includes load allowances for patient hoists that

are required to be suspended to the soffi ts of the structures in all patient bed rooms. An increased load allowance

of 5.00kN is required in the bariatric patient rooms (locations to be confi rmed)

• Super-imposed permanent load (Gk) = 1.00kN/m2 for ceilings and services plus additional permanent loads (in-

cluding insulation, waterproofi ng, roof fi nishes etc) to suit the proposed structural system.

i. The design and construction of the main hospital building is required to achieve satisfactory vibration behaviour to ensure the

comfort of the building users and to ensure the satisfactory functioning of the building.

The following vibration threshold limits are applicable to the bed ward fl oor structures in the bedrooms and in offi ce areas (to

allow for the potential future conversion of offi ce areas into bed rooms):

• Maximum Response Factor = 2.0

• Maximum Vibration Dose Value = 0.2 m/s 1.75

• Minimum Natural Frequency = 5Hz

• Maximum design value for damping ration = 3.0%

The following vibration threshold limits are applicable to the bed ward fl oor structures in the plant areas:

• Maximum Response Factor = 8.0

• Minimum Natural Frequency = 5Hz

• Maximum design value for damping ration = 1.1%

j. arts of the fl oor areas are required to be used as offi ce accommodation – open plan areas will be required in these locations.


Technical Service Corridor Ceiling Void Location Bedward Ceiling Void Location Recommendation

Advantages Disadvantages Advantages DisadvantagesChilled Water Pipework Access from the central corridor for main-

tenance - albeit there is limited need for on-going maintenance.

Pipework restricts ceiling void space for more maintenance intensive services

Its only the bedward air handling unit at the extremity of the bedward that is served from the chilled water pipework - so a single set of fl ow and return pipes can be retained within the bedward ceiling.

The plug and play” pre-fabrication concept is compromised as services will need to route through/over the pre-fabrication ele-ment.

Move the chilled water pipework to the bedward ceiling void space.

Taking the fl ow and return mains out of the corridor frees up space for more mainte-nance intensive servicec.

Heating Water Pipework Only one set of fl ow and return mains is required - more cost effective

Pipework restricts ceiling void space for more maintenance intensive services

The bedward heating system is generally located at the perimeter of the building - meaning the heating pipes are located closer to the fi nal terminals.


Move the heating water pipework to the bedward ceiling void space.

Access from the central corridor for main-tenance - albeit there is limited need for on-going maintenance.

Taking the fl ow and return mains out of the corridor frees up space for more mainte-nance intensive servicec.

Hot and Cold Water Pipework Only one set of mains is required - more cost effective

Most of the hot and cold water pipework to the bedwards serves the ensuite bath-rooms - so the pipes are located immedi-ately above the areas served.


Retain the hot and cold water pipework in the corridor ceiling void.

The pipework does not take up a great deal of space in the corridor ceiling space

Leaks or adaptions of the hot and cold wa-ter pipes can be restricted to one bedward room at a time.

Two sets of distributuion pipes would be necessary - additional cost.

Hot and Cold Water pipes are likely to adapt during the buildings lifetime - mean-ing the connections are easily extended/adapted in the corridor zone to limit bed-ward disruption.

BEDWARD TECHNICAL INSTALLATIONS DISTRIBUTION STRATEGY

Discussion has occurred during the consolidated design stage to assess the extent of MEP services to be

installed in the bedward corridor, and what MEP services could be transferred into the bedward ceiling space

to generate more future servicing/installation space in the bedward corridor ceiling void.

A schedule of MEP services to be installed in the bedwards was developed – with each technical service then

assessed regarding its pros and cons of installation in the corridor or the bedward ceiling spaces.

Part of this process was to assess what services require regular maintenance, what services may require

adaption during the lifetime of the Hospital, and what services may be best suited to a corridor or bedward

located pre-fabrication strategy. An extract from the schedule is identifi ed below:

TECHNICAL INSTALLATIONS DISTRIBUTION STRATEGY


Bedward perimeter zone pipework installed in-situ following installation of bedward module.

Bedward ensuite bathroom pod MEP technical services pre-fabrication module

Corridor MEP technical services pre-fabrication module

BEDWARD TECHNICAL INSTALLATIONS DISTRIBUTION STRATEGY

Based upon this assessment it was agreed that the following technical services

would re-locate from the bedward corridor, into the bedward ceiling space:-

• Heating Pipework.

• Cooling Pipework

• Wastewater Ventilation Pipework

A 3D REVIT model has now been developed of a typical bedward corridor section

to identify the crossover locations local to each en-suite bathroom unit, and the rela-

tively clearer ceiling void space that then exists between these crossover locations.

An assessment has then been undertaken to assess which technical installations

could be pre-fabricated – with the below sketch indicating the current strategy. As

can be seen, the main corridor ceiling void technical installations could be pre-fab-

ricated in standardised lengths. In a similar manner the bathroom en-suite services

could also be pre-fabricated as part of the bathroom pre-fabricated pod manufactur-

ing process.

This would leave the bedward located piped heating/cooling/wastewater ventilation

pipework to then be installed in-situ and following the installation of the bedward

pre-fabrication module.

INDICATIVE PROGRAMME FOR THE CONSTRUCTION OF THE BEDWARDS LEVELS


LIST OF POTENTIAL QUESTIONS FOR THE DIALOG

LIST OF POTENTIAL QUESTIONS FOR THE DIALOG

1. Please confi rm that the proposed structural system will be suitable for the proposed 2-3 storey bed ward structures.

2. Please provide a brief description of the proposed construction of the fl oor, roof and wall systems including drawings or

sketches to indicate the form of the proposed structure. It is proposed that the bed ward fl oor construction should comprise

concrete fl oor slabs therefore please provide details based on a concrete fl oor construction; alternative fl oor construction

details may be provided as alternative options for review.

3. Please provide a high level estimate of the programme requirements for the proposed system for this development ie ap-

proximate period of time for manufacture and approximate period of time for the construction of the structures to the bed ward

areas

4. Please provide a high level estimate for the cost of the manufacture and construction of the structures to the bed ward areas

5. Please provide approximate construction zones required for the fl oor and wall systems

6. Please confi rm whether it is possible to connect external cantilever balconies to your system. Please provide typical details

including details of any proposed thermal breaks.

7. Please confi rm the fi nishing works required to the units ie what fi nishing works are required to the internal walls; what fi nish-

ing works are required to the fl oors; what fi nishing works are external elevations

8. Can your system be installed with cladding connected to the panels/external walls prior to erection?

9. Please confi rm that your system can accommodate prefabricated bathroom pods. Please confi rm whether the bathroom

pods would be installed integrally with the proposed bed ward structural system or whether the bathroom pods would be

installed independently. Please confi rm whether the bathroom pods would be manufactured as single bathroom, double

bathrooms or quadruple bathrooms (ie double height prefabricated units).

10. In some locations, it will be necessary to provide double width accommodation, for example in kitchen areas. There is also a

potential requirement for double width accommodation being required to be provided in the future. Please provide a written

description to explain how double width spaces can be accommodated within the proposed structural system in the initial

construction period and as part of future modifi cation works.

11. There is a requirement to vertically extend the bed wards structures as part of future modifi cation works across part of the

footprint of the building to provide an additional fl oor area. Please provide a written description to explain how the proposed

structural system will be designed to accommodate these future adaptations. Also please provide a written description of the

proposed construction details and outline construction methodology for undertaking this future adaptations.

12. The second fl oor structure is proposed to be a reinforced concrete transfer slab. The top surface of the slab is generally

proposed to be level, although it would be possible to accommodate steps in the slabs, for example to accommodate prefab-

ricated bathroom pods. Please confi rm the approximate fl oor zone required for the proposed bed ward structure at second

fl oor level in order to understand the required level for the top of the transfer structure slab.

13. Please confi rm how the proposed bed ward structural system would apply load to the second fl oor transfer slab, for example

point loads at the corners of the rooms or line loads at the edges of the rooms.

14. Please provide a written description of the method of delivery and installation of the proposed structural system including

details of any requirements for areas of the site for prefabrication or assembly and an outline description of the craneage

requirements for the bed ward structures.

15. The current design requirement for the bed ward areas is for the structures to have 120 minute fi re resistance up to the up-

permost fl oor. This requirement is applicable up to third fl oor level in all areas of the building and is applicable up to fourth

fl oor level in the area of the future vertical expansion. Please provide a written description of the potential reduction in wall

and fl oor zones and also the potential cost reduction if the fi re resistance requirement was reduced to be 60 minutes for all of

the bed ward structures.

16. The stability of the structure up to second fl oor level is proposed to be provided via reinforced concrete shear walls

around the lift and stair cores. It would be possible for the stair and lift core walls to be constructed in reinforced con-

crete above second fl oor and these walls could be used to stabilise the bed ward structures. Please confi rm whether

the proposed bed ward structure system would require the stair and lift walls to be formed in reinforced concrete

above second fl oor level to stabilise the bed ward structures or whether the proposed be ward structures would be

designed for stability without the requirement to rely on reinforced concrete shear walls above second fl oor level.

17. Please provide drawings or sketches to indicate the proposed locations of structural movement joints within the bed

ward structures. It should be noted that due to the rectilinear grid system up to second fl oor level, it will be necessary

for the alignment of the structural movement joint above second fl oor level to differ from the alignment up to second

fl oor level. It will therefore be necessary for parts of the bed ward structures to be separated from the second fl oor

transfer structure in locations adjacent to the movement joints. Please provide confi rmation that the proposed bed

ward structural system can accommodate this requirement.

18. Please confi rm that the proposed bed ward structural system can be constructed in accordance with the requirements

of the Execution Class 3.

19. Please provide a written description of the proposed structural form in the offi ce areas.
