3D Drawing Services (in REVIT) for the European Joint Research Centre

3D Drawing Services

European Commission, Joint Research Centre (JRC), JRC.R – Support Services (Brussels), JRC.R.6 – Support Services – Geel, Belgium

Framework contract for 4 years / total budget €1.250.000

Deadline 13/1

Short description: JRC-Geel covers an area of 38 ha consisting of 21 buildings and approximately 20 cabins, of which thirteen buildings need to be modelled. The technical drawings and schemes of buildings and technical installations need to be maintained and updated. A previous contract started with the creation of new 3D building models and site plan(s) to map the existing condition. 2D plans were derived from these 3D models. Services include drawing in REVIT and management of the AutoCAD Vault database.

DESCRIPTION OF THE SERVICES

MODELLING OF EXISTING BUILDINGS AND TECHNIQUES

The tender includes the following services:

 Modelling of any new buildings or building components;

 Modelling of the mechanical parts in Revit MEP of the following buildings: 060 and 222.

Architectural models of building 060 are available. No architectural model is available of building 222 and will also have to be modelled, however, a point cloud is available of this building. As building 222 is a fairly recent building, the existing drawings of the infrastructure and internal technical installations are very accurate.

Modelling of the mechanical components of buildings 060 and 222 and modelling of the architectural model of building 222 can partly be done outside the JRC-Geel site. The remaining modelling is done on the spot at the JRC-Geel site. For this purpose, workstations will be made available. The contractor shall provide the necessary hardware, software and licences. The modelling takes place in accordance with set agreements that are bundled together in the document entitled “Modelling Guidelines” (annex II). At JRC-Geel’s request, modifications to this standard may be requested. The level of detailing is LOD 300 in accordance with the specifications of the BIM forum (see annex I). The contractor should provide an all-in price for these services.

CALCULATION OF THE BUILDING STRUCTURES

Based on the point clouds, we intend to calculate the building structure in 3D using Autodesk Revit in accordance with the drawing standard. The calculation of the building structures includes among other things the walls, roofs, windows, doors, false ceilings, foundations, etc.

In addition to 3D geometry, the intention is to provide the objects in the Revit drawing with the relevant data as described in the drawing standard. The contractor must provide these data in Revit so that a connection with Autodesk Vault is possible.

TECHNICAL INSTALLATIONS

The modelling of the technical installations is a major part of the tender. The technical installations include the following:

 Ventilation installations,

 Piping for heating, cooling, compressed air, technical gases, drinking water, extinguisher water, etc.

 Fire detection and extinguishing,

 Electrical installation, UPS, etc…,

 Installations for telephony and data,

 Other installations.

In addition to 3D geometry, the intention is to provide the objects in Revit drawing with the relevant data as described in the drawing standard. The tenderer must provide these data in Revit so that a connection with Autodesk Vault is possible.

CONNECTION BETWEEN REVIT AND AUTOCAD VAULT

The drawings in Revit are connected to an SQL database in Vault. The contractor shall ensure that the new drawings and data are formulated in a consistent manner so that the link between the two systems remains intact. For further information, please refer to the document “Vault Revit connection” (Annex III). Before it is possible to load the modelled models in Autodesk Vault, a screening of the objects and associated data is required. The basic check takes place via an automatic addon that is provided when the contract is awarded. It shall remain the contractor’s responsibility to ensure that the data are accepted in the Vault database.

ADJUSTMENT OF EXISTING PLANS IN THE EVENT OF MODIFICATIONS TO THE BUILDINGS

The buildings and technical installations on the JRC-Geel site are regularly modified. It is important that the building plans also remain up to date. The assignment also covers the adjustment of all plans for all models on the site based on the modification carried out.

JRC-Geel’s existing site plan will also have to be adapted in case of any changes and/or projects.

ADJUSTMENT OF EXISTING PLANS IN THE EVENT OF MODIFICATIONS TO THE BUILDINGS

Given that the quality of the existing plans varies greatly from building to building, work will take place on an hourly basis. The following profiles or tasks must be offered by the contractor:

 General project management:

o Work organisation and follow-up;

 Time management,

 BIM phases,

 Parametrisation and classification systems.

o Consultation with JRC-Geel regarding the strategy to be adopted;

 Regular work meetings with the JRC project manager.

o Contract management;

 Follow-up and reporting of work performed using detailed measurement records.

 Technical installations MEP, electricity and HVAC:

o Team leader;

 Time management,

 BIM-phases,

 Parametrisation and classification systems,

 Clash detection for model verification.

o Designer/ modeller (MEP/BIM);

 Analysis (mechanical, hydro-technical, parametric and spot plans),

 Creation of “family” elements in Revit, both static and parametric controlled.

o Functional analyst;

 Creation of objects and on-site measurements;

 Architecture:

o Team leader;

 Time management,

 BIM-phases,

 Parametrisation and classification systems,

 Clash detection for model verification.

o Designer/ modeller (BIM);

 Analysis (rooms, walls, etc…, parametrisation and spot plans),

 Creation of “family” elements in Revit, both static and parametric controlled.

o Functional analyst;

 Performing on-site measurements;

 Topography (3D scans):

o Team leader;

 Time management,

 Work preparation surveyors and monitoring their performance,

o Surveyor (including equipment);

o Technical assistant;

 Processing surveying data into a workable drawing in AutoCAD (possibly at the contractor’s office).

 AIM: Asset Information Management:

o Technical assistant;

 On-site assistance with loading of information in the database,

 Preparation of specification, extracting to *.dwg, *.dwf, *.pdf, etc… as per JRC-Geel guidelines,

 Setting up Views, Sheets and Schedules/Quantities in Revit.

COMPLETING AND KEEPING UP-TO DATE AUTODESK VAULT

 Completing and keeping up-to date the existing current as-build Revit models in the existing management platform (AutoDesk Vault) is an essential element when delivering the models. The elements and devices used will also need to be populated in an existing database.

 Publishing as-built extracts according to existing conventions in terms of naming and file formats (*.pdf, *.dwg, *.dwf en *.rvt).

MODELLING AND BIM

BIM – MANAGEMENT MISSION

The purpose of this mission is: the guidance of technical and organisational aspects of JRC in studies involving the use of BIM, as well as the implementation of the recommendations carried out by the BIM cell of the WTCB.

BIM will be applied in all phases of the project, from the study to the execution phase.

BIM SPECIFICATIONS

The successful tenderer will support JRC in defining its BIM specifications, taking into account the guidance documents already prepared within JRC, and reference persons designated by the lead official. A BIM management plan will be established.

It will define:

 A document explaining how the BIM model will be maintained and synchronised with the current model;

 The rules for managing configurations and changes to the BIM-model;

 The BIM interfaces and the method of exchange between the various project actors;

 Scenarios specific to the project to ensure maintenance of BIM-Data between the different software used by project stakeholders;

 How to transfer BIM data to JRC maintenance services;

 BIM-integration in the current model/plan management system.

ASSET MANAGEMENT PLAN, REQUIREMENTS LEVEL AND CODIFICATION

The successful tenderer, in collaboration with the services and reference persons designated by the maintenance department, will establish how parameterisation will be carried out at the object level. The following requirements will be made at the element level:

• A unique code and a consecutive main code,

• Level of detail: a description of the representative characteristics (geometry, details, colours, textures, materials) of the ‘family’ at each stage of the project or pre-project to completion),

• Information level: a description of the characteristics information (composition, coefficient thermal, …) of the ‘family’ up to each phase of the project (pre-project to delivery),

• Documentation on level: the required documents of the objects upon delivery,

• The successful tenderer will ensure that the various elements delivered by other project actors is integrated into JRC’s internal BIM model and will not compromise its consistency. He will be the point of contact for the various stakeholders in the questions of interfacing, specifications and formalism related to transfer information BIM.

MONITORING OF TECHNICAL CLAUSES SPECIFIC TO BIM

The successful tenderer will follow the technical clauses to ensure that the contractor will formalise exchanges with JRC in the BIM philosophy and that the information that will be sent is integrated into the internal BIM model.
