LADWP LAAFP UV Filtration Plant – Sylmar, CA

Key Personnel: Vishal Bora, LEED AP, Ben Kuhnel

The Los Angeles Department of Water and Power (LADWP) began the construction of a new ultraviolet (UV) water treatment facility at the Los Angeles Aqueduct Filtration Plant (LAAFP) in Sylmar, California, US.

The $60 million UV facility will provide an advanced level of protection to the LADWP’s treatment process, complying with new water quality regulations established by the US Environmental Protection Agency (EPA).

The new facility will provide protection against microbial contaminants that exist naturally in surface water sources and will reduce the use of chemical treatments, such as ozone and chlorine. The new treatment facility is expected to begin operations in April 2014.

ARCADIS became engaged with LADWP at the conceptual design phase of this project and is currently engaged in construction services.

Our services throughout the project included:

Establishing water quality and disinfection treatment goals
Developing UV design criteria for two UV disinfection plants
Developing overall disinfection plan for the complex
Developing on-line disinfection monitoring and CT calculation approach for ozone and chlorine disinfection
Evaluating how to optimize ozone monitoring to facilitate on-line ozone CT calculations
Evaluating site locations for constructability, costs and minimizing operational impacts during construction
Developing the conceptual, preliminary, and detailed designs
Assisting with overall design and construction management and design assistance on all disciplines
Performing hydraulic analysis and CFD modeling for hydraulic structures
Identifying operational strategies
Assisting with RFIs and design questions
Developing resource-loaded construction schedule
Providing coordination with the CDPH for facility permitting
Performing civil, electrical, instrumentation and control, HVAC, structural, and landscape design

The Design Phase of this project involved working with many staff within LADWP as well as many subconsultants.

ARCADIS coordinated this overall effort in order to deliver the design on time and in a format acceptable to LADWP.

The design phase involved the use of multiple design software including:

Autodesk AutoCAD
Autodesk Revit Architectural, MEP, and Structural
Autodesk AutoCAD Civil 3D
Autodesk AutoCAD P&ID

ARCADIS worked in conjunction with the multiple design disciplines to ensure proper coordination between all the drawings being developed.

4D Construction Simulation

ARCADIS utilized Navisworks to build a 4D construction management tool. A Revit model and AutoCAD Civil 3D model were linked with a Primavera schedule using Navisworks.

The resulting 4D Construction Simulation was used to develop and understand sequencing for:

Concrete slabs, walls, weir walls, and roof pours
Crane, materials and site accessibility
Trunk line piping installation and excavation
Complex underground electrical conduits installation
Mechanical Piping installation including flow-meters, UV reactors, valves, pumps and instrumentation
Mechanical systems installation including fire protection, HVAC, pumps and lighting
Electrical systems installation including under-ground & above-round conduits, switchgears, transformers, cable trays, Reactor PLCs and generators

Concrete slabs, walls, weir walls and roofs pour sequencing

Crane, materials and site accessibility sequencing

Trunk line piping installation and excavation sequencing, Complex underground electrical conduits installation sequencing

Mechanical Piping including flow-meters, UV reactors, valves, pumps and instrumentation sequencing, Mechanical systems including fire protection, HVAC, pumps and lighting sequencing

Electrical systems including under-ground & above-ground conduits, switchgears, transformers, cable trays, Reactor PLCs and generators sequencing.

ARCADIS services also included:

Training and development of a 4D Model with Autodesk Navisworks & Revit
Linking complex 3D model data from an integrated environment in Navisworks for fast 4D visualization of construction schedules and clear communication for identifying risk and reducing waste as a result of better planning control
Linking P6 schedule activities with thousands of Revit model 3D components and creating a 4D construction simulation with the Timeliner Tool in Navisworks
Downgrading P6 schedule by converting it to P3 format and then to MPX format, linking each conduit to its relevant pull-box and creating hundreds of selection sets to identify various 3D components
