New North Zealand Hospital Hillerød

Facade - Technical Dialogue05.10.2016

Project Overview

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 partner-ship 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 for an extensive use of wood in the overall design (cladding and/or window system) and the TC now wishes to further explore the various façade types and design by obtaining feedback from contractors, manufacturers and suppliers. For this reason we wish to enter into a number of Technical Dialogs with different contractors manufacturers and suppli-ers in order to take advantage of the knowledge and expertise in the market.

The Technical Dialogs will take place throughout the remaining part of the Project Proposal phase “Projektforslag”, and each Technical Dialog will be framed in a series of meetings with contractors, manufactures or suppliers within a period of 2 to 4 weeks, depending on which types or aspect of the façade design is being explored in the individual dialog.

TC have assembled this document to facilitate the discussions on which to base the Technical Dialogs. It is not expected to share more material relevant to the project during the Technical Dialogs; however the members of the TC to be part of the meetings can address any questions that you might have and that are neces-sary to conduct the meetings. You are expected to be prepared for the meetings, include key members of your technical team, acquire an understanding of the background documents and provide preliminary replies to the technical queries raised. These meeting are planned to be in English and will unless otherwise agreed take place at VLA’s offi ce in Copenhagen as a Video Conference with HdeM’s the design team in Basel.

Although the primary goal of this dialog is exchanging on the technical aspects of the facade design the discussions could evolve around the time and cost con-straints of the project.

You are kindly requested to confi rm by return your availability and acceptance to participate in this Technical Dialog to the following email address:[email protected] (Lars Beier) and cc: [email protected] (Enrique Pelaez).
