January 2012 Overview of the PHIMF construction. As shown in the photo, the access road connecting the Puente Hills MRF to the PHIMF has been constructed up to the Union Pacific Railroad right of way. Upon completion of the railroad bridge, excavation of the remaining portion of the access road will begin. Construction of the administration and maintenance building, installation of onsite utilities and drainage, and erection of perimeter block walls continues at the PHIMF site.
	December 2011 Drilling and installation of soldier piles along a 3-mile segment of Union Pacific Railroad right-of-way continues. As soldier piles are completed, precast wall panels are placed between the piles to form a retaining wall that will provide adequate horizontal clearance for the construction of a new staging track for PHIMF operations.
	December 2011 Interior of the administration building with structural framing erected and rough-in electrical, plumbing, HVAC, and fire sprinklers installed.
	November 2011 The installation of structural elements of the administration building continues.
	September 2011 The grading activities for the internal access roads connecting the Puente Hills MRF and the PHIMF was completed. Once the roads are paved, the exterior walls for these roads will be poured.
	August 2011 An administration and maintenance building will be constructed to serve the PHIMF. The concrete masonry blocks were placed for the maintenance building and the structural steel frame for the administration building was erected. Other work at the PHIMF includes utilities installation to provide electricity, water, and communication to the PHIMF.
	July 2011 The project involves the installation of more than 2000 solider piles for the retaining wall along Union Pacific Railroad right of way. The installation of these piles are ongoing and will continue through most of the project's duration.
	June 2011 The bridge supporting the southern portion (eastbound lanes) of Workman Mill Road was constructed and all lanes on Workman Mill Road were reopened on July 1. The second bridge in the photo will provide access for employees to access the west side of the property from the PHMRF.
	April 2011 Overview of the PHIMF construction. The offstreet access road that will connect the PHMRF to the PHIMF can be clearly seen in this photo.
	March 2011 Work in the Union Pacific right-of-way started in January 2011 with clearing, grubbing, and minor grading adjacent to the future PHIMF site. This will allow the contractor to build a track that will divert the existing rail lines around the construction area for the future access road. This access road will eventually directly connect the PHIMF to the PHMRF.
	February 2011 Grading at 2500 Pellissier was completed in February 2011. Current work at the site includes the installation of subsurface utilities and building pads for the future administration and maintenance buildings. The construction of the eastern perimeter wall is almost complete and will serve as a visual barrier with our neighbors on the east.
	December 2010 Temporary fencing was being installed around the site and will be in place for the next two years. The contractor is also preparing the eastern boundary of the site for the perimeter wall that will be built in late December/early January.
	December 2010 Construction of the Puente Hills Intermodal Facility and Railroad Improvements project started on December 6, 2010 at 2500 Pellissier Place, the site of the future PHIMF. The contractor started by clearing and grubbing the site and then continued with minor grading of the southwestern portion of the site.
	November 2010 The sides of the reconfigured storm drain was poured and the falsework and steel reinforcement for the deck are being installed.
	October 2010 The invert for the reconfigured storm drain was poured and the falsework and steel reinforcement for the side walls are being installed. The alignment of the dedicated access road can be seen under the reconstructed Workman Mill Road bridge.
	September 2010 Asphalt and paving of the southern lanes and sidewalk of Workman Mill Road were removed to prepare for the excavation and reconfiguration of a 10' x 12' reinforced concrete storm drain.
	August 2010 Construction of retaining walls and grading for new roads at the Puente Hills Materials Recovery Facility continued.
	July 2010 Overview of project construction.
	June 2010 Half of the Workman Mill Road bridge has been completed.
	May 2010 Grading for access road continues at the Puente Hills Materials Recovery Facility.
	April 2010 Rebars are placed in preparation for pouring concrete in the bridge deck.
	April 2010 The soldier pile caps for the retaining wall outlines the alignment and width of the future dedicated access road.
	March 2010 Soldier pile retaining wall continue to be installed to support the future dedicated access road.
	February 2010 Overview of construction at Workman Mill Road.
	January 2010 All work related to site demolition was completed.
	December 2009 A sewer siphon was constructed to allow for the removal of two existing sewer lines that were within the construction limits of the Workman Mill Road and access road improvements.
	November 2009 Concrete from demolition activities is recycled and processed at the site for reuse.
	October 2009 Demolition of the warehouse building was completed.
	August 2009 A demolition contractor removed the roof of the existing warehouse building at the future Puente Hills Intermodal Facility site. Salvaging of recyclable and recoverable interior building materials, such as lumber and steel, continued through Summer 2009.
	June - August 2009 Multiple utilities, such as a potable water pipe and a natural gas line, were relocated to facilitate the construction of a dedicated access road between the existing Puente Hills Materials Recovery Facility and the future Puente Hills Intermodal Facility. The two facilities are separate by Workman Mill Road and the Union Pacific Railroad tracks.
	June 2009 Partial lane closure began at Workman Mill Road to accommodate construction.
