CONCRETE WALL ELEVATION NOTES

1. THE MINIMUM REINFORCEMENT IS INDICATED IN 1/SF505, AND IS NOT ALL SHOWN ON THESE

ELEVATIONS. WHERE REINFORCEMENT IS NOT OTHERWISE SHOWN ON THESE

ELEVATIONS, PROVIDE THE MINIMUM REINFORCEMENT FROM 1/SF505.

2. VERTICAL CONSTRUCTION JOINT AND CONTROL JOINT LOCATIONS ARE SHOWN

ON THE PLANS. FOR CONSTRUCTION AND CONTROL JOINT DETAILS, SEE SF505.

DO NOT SUBSTITUTE VERTICAL CONSTRUCTION JOINTS FOR CONTROL JOINTS OR

VISE VERSA WITHOUT APPROVAL OF THE ENGINEER OF RECORD FOR THE LOCATION

REQUESTED.

3. VERTICAL CONTROL JOINTS HAVE BEEN LAID OUT SUCH THAT IF THE WALL IS

POURED FULL HEIGHT IN ONE POUR (MULTIPLE LIFTS), VOLUMES OF POUR WILL

USUALLY FALL BETWEEN 30-40 CUBIC YARDS (CY). SOME POURS IF PERFORMED

FULL HEIGHT WILL APPROACH 50 CY. DO NOT PERFORM SINGLE POURS GREATER

THAN 50 CY WITHOUT APPROVAL OF THE ENGINEER OF RECORD AND THE

CONTRACT OFFICER.

4. ALL HORIZONTAL JOINTS SHOWN AS CONSTRUCTION JOINTS MAY BE CONSTRUCTED

AS CONTROL JOINTS, PROVIDED THE SINGLE POUR VOLUME LIMITS OF NOTE 3

AND THE INDIVIDUAL LIFT LIMITS OF ACI ARE OBSERVED. INTERCHANGEABILITY BETWEEN

HORIZONTAL CONTROL AND CONSTRUCTION JOINTS IS INTENDED TO ALLOW THE

CONTRACTOR FLEXIBILITY TO PLAN INDIVIDUAL POURS OF A SIZE THAT IS CONSITENT

WITH THEIR QUALITY CONTROL PLAN AND CREW ABILITY TO MAINTAIN QUALITY FOR

LARGER POURS.

5. VAULT WALLS HAVE A REINFORCING SIZE AND SPACING THAT DIFFERS FROM THE

DEFAULT REINFORING ON 1/SF505. FOR VAULT WALL LOCATIONS, SEE PLAN ON

SB106.
