SharePoint implementation for LA Expo

Expo Line Construction Authority is the independent agency that was charged with building the transportation line that was funded by Measure R in Los Angeles. This included seven new stations between Culver City and downtown Santa Monica in Los Angeles, CA. The $1.5-billion project completed the line to Santa Monica and added seven new stations.


LA Expo was given the authority to plan, design, and construct a light rail line that ran between Santa Monica and downtown Los Angeles. They partnered with Calance to create the required integration between systems to reduce redundant data entry, improve data integrity, and reduce the effort required to provide adequate project accounting and controls between SharePoint and Primavera. Expo employed several systems to provide the necessary project controls and accounting for its many projects.

Our Solution

Calance worked with LA Expo to review the existing set-up of their SharePoint 2010 and to define, design, develop and deploy necessary custom-built integration points. This included the integration requirements to Primavera and the financial system and therefore, the user and data integrity requirements of both SharePoint and Primavera were set up. These included the document upload interface and the following integration points: invoices, direct payments and actual costs. Specifically, this was the integrations between Primavera Contract Manager, Priimavery P6, the financial system and SharePoint 2010.


The integration was built and completed on time and within a budget of under $250,000. After the implementation, LA Expo noticed a reduction of manual effort required to maintain data integrity while improving their overall experience on both SharePoint and Primavera. This was due to the fine-tuning of their user experience through development efforts. In addition, the integrations allowed for accurate and seamless flow of data between systems which reduced direct operational costs. Following the completion of the project, Calance was awarded the support contract and hosting contract for not only the integration but also for each of the individual systems. Calance supported LA Expo through to the close of the project in 2019. LA Expo’s Project Manager, Roslyn Lewis remarked, “Calance provided great support for the document control system I worked with at Exposition Construction Authority. The team was very responsive to my requests and to resolving any problems that would come up with the system.”
