# Avenant d'honoraires V2 : studio d'enregistrement, Akademie Neue Klänge

## Variation V2

### Adding the recording suite

*Fee variation V2*

Akademie Neue Klänge, rehearsal building. Decision needed by Friday 4 June 2027: make this change, or keep the current scope.

*Concrete and oak recording room with one strip of light*

*Aigner Reisch Architekten mark*

## What changed

### A new room below the hall

*What changed*

On 10 May, Clara Wieser asked us to add a 186 m² recording suite beneath the main rehearsal hall.

The appointment of 18 January covers a rehearsal building with a plant basement. A new donor agreement now funds recording facilities.

The room needs its own floated structure, so the basement slab, part of the frame and the services routes all change. Stage work done so far stands. This page prices the change only.

## The impact

Four numbers, each measured against the current scope.

### Our fee, excluding USt

**+€38,740**

### Estimated build cost

**+€412,600**

### Weeks to permit submission

**+5**

### Gross floor area

**+186 m²**

## The choice

Both answers are workable. Adding the suite now costs less than adding it later, and leaving it out costs nothing today.

## The change

### The change, priced

EUR, plus 20 percent USt. Built from our agreed hourly rates. This is additional to the appointment fee, which does not change.

#### Variation V2

| Item | Price |
| --- | --- |
| Basement and structure redesign | $14,280.00 |
| Acoustic consultant coordination | $5,460.00 |
| Services coordination | $7,920.00 |
| Amended permit drawings | $6,180.00 |
| Project management | $4,900.00 |

#### Optional add-ons

| Item | Price |
| --- | --- |
| Isolation mock-up review | $3,260.00 |
| VR listening walkthrough | $2,480.00 |
| Early contractor pricing | $1,940.00 |

- USt: 20%

## If you approve

Three steps, in this order.

### 1. Acoustic consultant appointed, by 4 June

Your appointment. We need their brief for isolation and background noise before the slab is redrawn.

### 2. Redesign starts, Monday 7 June

Structure first, then services. The other rooms stay as drawn.

### 3. Permit submission, Monday 9 August

The amended Einreichplanung goes to the Baubehörde five weeks later than the current 5 July date.

## Revised programme

With the variation. The permit date moves by five weeks and tender documents by four. Site start stays in spring 2028. We plan for 12 weeks at the Baubehörde, and that period is outside our control.

| Task | Start | End | Duration | Label |
| --- | --- | --- | --- | --- |
| Structure redesign | 2027-06-07 | 2027-07-02 | 5 days | Design |
| Acoustic design | 2027-06-07 | 2027-07-16 | 5 days | Design |
| Services coordination | 2027-06-21 | 2027-07-30 | 5 days | Design |
| Cost check | 2027-07-26 | 2027-08-06 | 5 days | Design |
| Permit submission | 2027-08-09 | 2027-08-10 | 5 days | Permit |
| Baubehörde period | 2027-08-10 | 2027-11-02 | 5 days | Permit |
| Tender documents | 2027-09-13 | 2027-11-26 | 5 days | Tender |

## Assumptions

### Assumptions, and what stays the same

What the price rests on, and what happens if you say no.

### What stays the same

The appointment fee and the rest of the design. The hall, foyer and teaching rooms are not redrawn. Payment terms stay at 14 days.

### If you don't make this change

We continue on the current scope, with no fee change and the 5 July submission date intact. The basement stays a plant room.

Adding the suite after the slab is cast would mean underpinning. We estimate at least €190,000 more in build cost.

### What this price assumes

One suite of 186 m², one control room, one isolation booth. One round of client comments. An acoustic consultant in place by 4 June.

### What it excludes

Acoustic consultant and structural engineer fees, recording equipment, permit fees and any donor reporting.

### Build cost estimate

€412,600 is the quantity surveyor's estimate at ±10 percent, dated 21 May. It is not a tender price. The cost check in July updates it.

## Decision

### Your decision, by Friday 4 June

To go ahead, approve below. To keep the current scope, reply to Theresa with one line. We need nothing else, and the 5 July date stands.
