As built documentation for a Design submission - updated

Technical Clarification Number
GEN00-T-OB1-1541

(REPLACES GEN00-T-OB1-0566 issued 2012-09-11)

Guidance
2016-08-12

Green Star SA awards buildings at two phases, the DESIGN and AS BUILT stage with certifications where the required criteria has been achieved of the specific rating the project has been registered for. The DESIGN stage certification awards the project team’s design as instructed to the contractor and the AS BUILT rewards the final constructed Green Star SA registered building.

Green Star SA assessors are instructed to assess buildings under ONE of these rating types (Design OR As Built), and as such the GBCSA will not accept AS BUILT documentation as part of the DESIGN submission.

(The GBCSA are happy to accept isolated cases of As Built evidence for a Design rating, but are not comfortable where this occurs on many credits because this should then have been an As Built rating.

 This will be case specific, please submit your TC/CIR to the GBCSA for consideration.)



The GBCSA are not able to allow the precedent of accepting both Design and As Built documentation within one submission as this could have unintended consequences including but not limited to the following:
• Confusion and complexity in assessment through the misalignment in documentation and the stage at which the documentation was produced.
• The Design certification may not be a true reflection of the building’s design. I.e. projects can be awarded for designing in accordance with certification requirements even if this was not achieved in the design process.
• Projects completing Design ratings after practical completion in order to submit As Built documents where the Design criteria is not met.

For this reason the GBCSA encourages project teams to register for an AS BUILT certification so as to be awarded for those instances where the project team has gone beyond their contractual obligations that were agreed upon during the DESIGN phase.

Technical Clarification

Base Building Scope definition

Technical Clarification Number
GEN00-T-OB1-1384

Guidance
2016-04-18

The GBCSA confirms that Base Building Scope is defined as:

All elements of the building which are to be completed as per the Base Building Contract (which are under the direct control of the building owner, to deliver either a new building or an extensive refurbishment).

As a minimum this scope must include the following elements:
· All new structural elements of the building
· A complete façade / new building envelope
· Central HVAC services including: completed HVAC equipment to serve common areas, risers and HVAC equipment (e.g. ducting) to within 1m of risers on tenanted floors
· Building Services to all common areas and provided to within 1m of risers on tenant
· Lighting to common areas
· Finishes (floor coverings, wall coverings and ceilings) to common areas
· Bathroom amenities
· Service corridors, fire stairs and lifts

As a maximum (i.e. For projects where the final building, including fitout, is delivered within a single contract) the base building scope could include:
· All structural elements of the building
· A complete façade
· Central HVAC services including: HVAC equipment to all areas, risers, all HVAC equipment (e.g. air, cooling and heating provisions) to entire building
· Building Services to entire building
· Lighting to entire building
· Finishes (floor coverings, wall coverings and ceilings) to entire building
· Bathroom amenities
· Service corridors, fire stairs and lifts
· Furniture

It is expected that the majority of projects will sit somewhere on the continuum between these scopes, and in many cases this may vary within the building depending on the agreement with individual tenants.

The project team/GSSA AP is to clearly define the project specific Base Building Scope within the General section for each submission; the defined scope must remain consistent across the entire submission.

 

 

 

Technical Clarification

Design Specification(s) and Short Report(s)

Technical Clarification Number
GEN00-T-OB1-1301

Guidance
2016-02-22

For a design rating where product(s) have not yet been specified at the projects tender stage, a performance specification requiring that all relevant product(s) comply with the credit criteria is acceptable. Where products are yet to be confirmed/ specified, this should be stated in the short report.

This applies to the following credits in particular: 

  • IEQ-13 Volatile Organic Compounds 
  • IEQ-14 Formaldehyde Minimisation 
  • MAT-8 Sustainable Timber
  • EMI-4 Insulant ODP 

 

 

Technical Clarification

As Built or Record drawings

Technical Clarification Number
GEN00-T-OB1-1205

Guidance
2015-12-23

The GBCSA confirm that it is acceptable in terms of Green Star SA to provide either "As Built" or "Record" drawings in your Green Star SA project As Built Submission.
  
The GBCSA provides the following clarification in this regard:

The American Institute of Architects defines:
Record drawings: Record drawings are prepared by the architect and reflect on-site changes the contractor noted in the as-built drawings. They are often compiled as a set of on-site changes made for the owner per the owner architect contract.

In the South African context the industry typically uses the term “As Built” drawings to describe what “Record” drawings are (as defined above), and thus both of these are acceptable when describing the status of a drawing in the title block, in the context of a Green Star SA As Built submission. Hand marked up drawings are not accepted for As Built or Record drawings in a Green Star SA submission.

Typical Floor Plan submission for multi-storey buildings - motivation

Technical Clarification Number
GEN00-T-OB1-1215

Guidance
2015-07-15

In line with TCE GEN0_T-OB1-446 (issued on 2012-05-22), projects making use of typical layouts or floor plans need to provide a motivation. The GBCSA provides the following clarification with regards to the motivation required:

 

Project teams are to motivate that their typical layouts are representative of the rest of the building by indicating that the equipment used in the typical layouts will be used in a similar fashion throughout (same HVAC system, no significant variation in fitting types,  similar density of fittings, outlets etc.) and referencing other project documentation like specifications, tenant lease specifications and equipment/lighting schedules that are consistent with what has been indicated on the typical layout. Where there might be a significant change in density of equipment (e.g. influencing air flow rates adjacent to highly glazed areas, highly cellular spaces) – it is to be demonstrated that this is accounted for in the typical layouts or the inputs in to the relevant credit adjusted based on a conservative quantified manner.

USABLE AREA (This TC supercedes GEN00-T-OB1-0846)

Technical Clarification Number
GEN00-T-OB1-0858

Guidance
2015-02-12

Office Projects may choose to exclude from their Usable Area (UA) space types that are designed as part of the base building delivery to have considerably different operating characteristics to that of office space. Such space types would not typically be occupied as office space by current or future tenants of the building and have a high likelihood of having the building systems and finishes significantly altered should a new tenant move into the building at a later stage or the space needs of the current tenant changes. This approach should however be applied consistently across relevant credits. Examples of such spaces typically include:
• patch rooms and data centres
• cafeteria
• large kitchens with serving canteens etc (not small tea kitchens, which are included with UA)
• raked auditoria
For each credit where this exclusion applies, the project team is to include a short explanation in the short report (or cover sheet if no report is required) as to why the space is being excluded for that particular credit in light of the logic described above.
These areas however must still form part of the office GFA which is referenced in various credits and used to calculate eligibility, unless it can be demonstrated that these operate as separate tenants in the building and should be excluded.
All other existing Usable Area definitions and related TC’s still apply, and this TC does not supersede those.

'Contract Value' - definition

Technical Clarification Number
GEN00-T-OB1-0515

Guidance
2012-06-14

This Technical Clarification supersedes GEN00-T-OB1-0028 issued on 2009-03-30.
The GBCSA provides the following guidance:

Contract Value is defined as the Rand value that will be required to complete the works for the entire project, including site works (landscaping, external paving, etc.). The contract value must include contractor fees, contingencies and any other items included as part of the contract amount.


There are a number of credits [e.g. Reused Materials (Mat-3), Concrete (Mat-5), Steel (Mat-6), Sustainable Timber (Mat-8)] that reference this definition of Contract value.
As such, the following items must be excluded when using the contract value for calculations of such credits:
• Preliminaries;
• Demolition works;
• Consultants, design fees, project management fees;
• Works outside the site area; and
• Buildings or areas within the site that are not being assessed for purposes of Green Star SA.

Where a number of amenities or services are shared between buildings, the cost apportioned to the Green Star SA registered building must be equivalent to the use that the building will have of these facilities (e.g. if a shared parking has 100 spaces but 40 are being allocated to the Green Star SA registered building, then 40% of the car park cost must be allocated to the project’s contract value).

A letter from a Quantity Surveyor or cost planner showing the breakdown of the excluded costs and the total cost for the project undergoing the Green Star SA rating must accompany the documentation submitted as evidence towards the projects Green Star SA assessment.

 

Technical Clarification

Typical Floor Plan submission for multi-storey buildings

Technical Clarification Number
GEN00-T-OB1-0446

Guidance
2012-05-22

The GBCSA recognises that in a multi-storey building (such as a high-rise building) there may be typical floor plans i.e. floor plans that have exactly the same perimeter wall construction, configuration/layout and size.
In addition, there may be typical building services layout drawings representing a number of floors, where the configuration, layout and size of these floors do not vary in such a way as to affect compliance with credit criteria of particular credits in the rating tool.

The following provides guidance where a multi-storey building has a typical floor plan(s):

Where the ‘Documentation Requirements’ (for Design and/or As Built) requires any plan drawings as evidence that confirms compliance, the submission and inclusion of typical floor plans is acceptable, provided that for that specific credit, compliance with the credit criteria will not vary per floor. Where typical floor plans are used, the following documentation should be submitted:

• A brief description motivating that for the specific credit in question, compliance with the credit criteria will not vary per floor represented by the ‘typical floor’ plan(s). This can be given in the Short Report where applicable or as a separate document preceding the drawings.
• ‘Typical floor’ plan drawing(s) clearly marked and named as such and submitted in accordance with the stipulated documentation requirements for the relevant targeted credit.

Scope of delivery – ‘Conventional’, ‘Integrated’ and ‘Shell & Core’
(REPLACES GEN00-T-OB1-0048 issued 16 Oct 2009)

Technical Clarification Number
GEN00-T-OB1-0380

Guidance
2012-01-11

The following provides guidance as to the scope of delivery for Conventional, Integrated and Shell & Core:

Conventional Delivery:
Common Areas - Finishes (e.g. floor coverings and paint) and services are applied to common areas (as applicable).
Tenant Areas - Tenancies are delivered with ceilings, finishes (e.g. floor coverings and paint), generic mechanical services (e.g. ducts from air supply and return risers, or other HVAC equipment, with generic control zone/diffuser/return layouts), generic electrical services (e.g. generic lighting layout) and complete wet services. The fitout to tenant areas is intended to be generic and non-tenant specific.

Integrated Fitout:
Common Areas - Finishes (e.g. floor coverings and paint) and services are applied to common areas (as applicable).
Tenant Areas - Tenancies are delivered with ceilings, finishes (e.g. floor coverings and paint), specific mechanical services (e.g. ducts from air supply and return risers, or other HVAC equipment, with fitout specific control zone/diffuser/return layouts), specific electrical services (e.g. fitout specific lighting layout) and complete wet services. The fitout to tenant areas are tenant specific.

Shell & Core:
Common Areas - Finishes (e.g. floor coverings and paint) and services are applied to common areas (as applicable).
Tenant Areas - Tenancies are delivered with no ceilings, floor coverings, lighting systems nor partition walls. Mechanical services are not installed within tenant areas, with ducts from air supply and return risers finishing within 1m of the face of the riser (for central air systems), or no other tenant-side systems installed (e.g. indoor units). A raised floor or underfloor air distribution (UFAD) system may be installed in a Shell & Core scenario provided floor coverings are not installed. No fitout is provided in a Shell & Core scenario.

This Technical Clarification is applicable to Mat-3 Reused Materials, Mat-6 Steel, Mat-7 PVC Minimisation, Mat-8 Sustainable Timber, Mat-9 Design for Disassembly, Mat-10 Dematerialisation and Mat-11 Local Sourcing.

Where the ‘Documentation Requirements’ (for Design and As Built) request a ‘Short report’ and a ‘Quantity Surveyor report’, if the ‘Short report’ is prepared by the Quantity Surveyor, it is permitted that one consolidated report satisfying both ‘Documentation Requirements’ be submitted instead of two separate documents.

Where the ‘Short report’ is not prepared by the Quantity Surveyor (e.g. green building consultant, Accredited Professional, structural engineer etc.), both the ‘Short report’ and ‘Quantity Surveyor report’ must be submitted independently.

The purpose of the ‘Quantity Surveyor report’ is to validate data (e.g. quantities, costs, Project’s contract value etc.) referenced within the ‘Short report’.

The registration date used to determine the applicability of TCs and CIRs published on the GBCSA website (where within the TC/CIR it is indicated as dependent on registration date) is deemed as the date of first registration of the project for a Green Star SA certification under a particular rating tool, independent of whether it is Design or As Built certification.

 

Technical Clarification

Usable Area (UA) and Gross Floor Area (GFA)

Technical Clarification Number
GEN00-T-OB1-0350

Guidance
2011-11-23

The GBCSA recognises that determining and recording the UA and GFA of a project for Green Star SA is often performed using CAD, with the resulting CAD drawings unlikely to be issued “For Tender”, “For Construction” or “As Built” and are more likely to be issued “For Information”. To reduce Green Star SA documentation related activities, drawings prepared to calculate and demonstrate UA and GFA  are not required to be issued “For Tender”, “For Construction” or “As Built”  and issued “For Information” drawings will be accepted. This is strictly for the purposes of demonstrating the UA and GFA only. Please note that all other drawings submitted for the purposes of Green Star SA must be issued “For Tender”, “For Construction” or “As Built” as per the particular credit documentation requirements as stipulated in the relevant Green Star SA Technical Manual.

Technical Clarification Number
GEN00-T-OB1-0091

Guidance
2010-07-27

Where extract(s) from specification(s) are required in the Documentation Requirements for a credit, actual pages from project-specific specification(s) are required, showing the project name and revision, and all requirements for the ‘extract(s) from specification(s)’ prescribed in the Documentation Requirements for the credit. Where the project name and/or revision does not appear on every page of the specification(s), it is acceptable to include the relevant extract page(s), complete with the specification(s) cover sheet(s) indicating the project name and revision. Text copied from specifications into Green Star SA reports or letters does not demonstrate the same contractual obligation and is not acceptable. Product data sheets on their own do also not substitute for specifications, as they do not demonstrate the same contractual obligation. It is acceptable to replace general product requirements with the specification of a specific product, as long as a manufacturer's product data sheet is provided for the product, demonstrating compliance with the relevant criteria required by the Documentation Requirements. The specification and product data sheets together must still include all requirements of the ‘extract(s) from specification(s)’ prescribed in the Documentation Requirements for the credit.
