EXPLANATORY NOTE 
Engineering districts are vital components in the country’s development. Without their 
invaluable contributions, the implementation of priority projects, such as the construction, 
maintenance, and rehabilitation of roads and bridges, as well as flood control, irrigation, and 
other essential infrastructure, would be impossible to realize. 
Before the passage of Republic Act No. 11609 on December 10, 2021, which created the Second 
District Engineering Office of the Province of Davao de Oro, the whole political subdivision 
comprising eleven municipalities was under the jurisdiction of a single district engineering 
office. RA 11609 changed all that, with the Second District Engineering Office now mandated 
to provide its services to five of the eleven municipalities. 
Inadvertently, the new law created confusion, as the First District Engineering Office, located 
in the capital town of Nabunturan, covers the municipalities of the Second Legislative District. 
In contrast, the Second District Engineering Office, with its office address in the municipality 
of Compostela, has jurisdiction over municipalities belonging to the First Legislative District. 
This has caused much administrative bewilderment among agencies, including the Central 
Office of the Department of Public Works and Highways. 
As a legislative remedy is required to fix this perplexity, the undersigned sponsored this bill, 
which interchanges the names of the first and second district engineering offices of the 
province—a simple solution to an otherwise innocuous and unintentional conundrum. 
During the 19th Congress, this bill was filed by the undersigned and received endorsement 
from the Committee on Public Works and Highways. It was approved on the third reading 
by the House of Representatives and subsequently transmitted to the Senate.  
We earnestly request the immediate approval of this measure.
