The highest value lot for projects over £15m saw Bowmer & Kirkland, BAM and Kier drop out to be replaced by Andrew Scott and Interserve this time around.
They join Morgan Sindall, Bouygues and Willmott Dixon which all retained their places.
Carmarthenshire County Council, in association with Neath Port Talbot County Borough Council, Pembrokeshire County Council, Ceredigion County Council and Swansea Council, will use the panel of firms.
The framework will also be open to blue light services and NHS Trusts to construct, refurbish and repair buildings for the next four years, until 2024.
