WINDOW FRAMES BEFORE SETTING (USE WINDOWS THAT ARE WATER
• 26 GA. G.I. FLASHING REQUIRED AS SHOWN IN OTHER WINDOW DETAILS TO BE INSTALLED BY SHEET METAL
CONTRACTOR.
• ADDITIONAL MATERIALS, i.e. METAL HEAD FLASHING, ELASTOMERIC SHEET WATERPROOFING, ETC. MAY
OCCUR (DEPENDING ON THE SPECIFIC FINISH MATERIALS BEING USED) - REFER TO INDIVIDUAL DETAILS
FOR ADDITIONAL INFORMATION.
• LINE WIRE (WHEN USED AS BACKING TO SUPPORT WATER-RESISTANT BUILDING PAPER OR FELT BENEATH
LATH FOR STUCCO) SHOULD BE INSTALLED ACCORDING TO INDUSTRY STANDARDS AND PRACTICE. NO
ATTACHMENT DEVICE, NOR THE WIRE BACKING, SHOULD COVER OR PENETRATE THE FLASHING
MATERIAL. PERIPHERAL FLASHING AT ALL EDGES OF WALL OPENING MUST COVER WIRE BACKING.
• APPLICATION OF FINISH MATERIALS OVER FLASHING MATERIALS SHOWN SHALL BE AS SPECIFIED BY CODE

Footing systems on expansive soil shall be constructed in a manner that will minimize damage to the
structure from movement of the soil. All soil in the City of Los Angeles is considered expansive unless
proven otherwise by an approved soils report.
1. Depth of footings below the natural and finished grades shall not be less than 24 inches for exterior
and 18 inches for interior footings.
2. Exterior walls and interior bearing walls shall be supported on continuous footings.
3. Footings shall be reinforced with four ½-inch diameter deformed reinforcing bars. Two bars shall be
placed 4 inches from the bottom of the footing and two bars within 4 inches from the top of the footing.

inches thick and shall be reinforced with ½” diameter deformed reinforcing bars. Reinforcing bars
shall be spaced at intervals not exceeding 16 inches each way.
5. The soil below an interior concrete slab shall be saturated with moisture to a depth of 18 inches prior
to placing the concrete.
6. All drainage adjacent to footings shall be conducted away from the structure by a 3-ft wide sloped

3. Identify diversion facilities where the construction and demolition waste material collected will be
taken.
4. Identify construction methods employed to reduce the amount of construction and demolition waste
generated.
5. Specify that the amount of construction and demolition waste materials diverted shall be calculated
by weight or volume, but not by both.

enforcing agency, which can provide verifiable documentation that the percentage of construction and
demolition waste material diverted from the landfill complies with Section 4.408.1.

materials will be diverted by a waste management company.

building site, provide readily accessible area(s) that serves all buildings on the site and are identified for the
depositing, storage and collection of non-hazardous materials for recycling, including (at a minimum) paper,
corrugated cardboard, glass, plastics, organic waster, and metals, or meet a lawfully enacted local recycling
ordinance, if more restrictive.
Exception: Rural jurisdictions that meet and apply for the exemption in Public Resources Code Section
42649.82 (a)(2)(A) et seq. are note required to comply with the organic waste portion of
this section.

* Allowable soil bearing capacity is based on the minimum values of Chapter 18 of the California Building Code. Client is responsible to
determine that the soil conditions match the code intent description, as well as for hiring a Geotechnical Engineer to confirm site conditions
before any excavation work is performed and during the construction of the proposed structures.
All engineering services are performed on the basis that the information used is current and correct. The information may consist of, but not
limited to information supplied by the client regarding the structure itself. It is the responsibility of the client to ensure that the information
provided to One-O-Eight Consulting is correct and complete. All services are performed, resultes obtained, and recommendations made in
accordance with generally accepted engineering principles and practices.

Value provided is 3-second gust wind speeds at 33 ft above ground for Exposure C Category, based on linear
interpolation between contours. Wind speeds are interpolated in accordance with the 7-22 Standard. Wind speeds
correspond to approximately a 7% probability of exceedance in 50 years (annual exceedance probability =
0.00143, MRI = 700 years). Values for 10-year MRI, 25-year MRI, 50-year MRI and 100-year MRI are Service
Level wind speeds, all other wind speeds are Ultimate wind speeds.
Site is not in a hurricane-prone region as defined in ASCE/SEI 7-22 Section 26.2.
