On June 1, 1978, the former 4th PC Zone stationed at Camp Parang in Maguindanao was divided into four commands, which led to the creation of the Philippine Constabulary/Integrated National Police Regional Command XI pursuant to General Orders Number 126, HPC/INP dated 01 June 1978 with its assigned areas of responsibility covering the areas of Davao del Norte, Davao del Sur, Davao Oriental, Surigao del Sur, South Cotabato, Davao City and General Santos City.
Before its creation, the Aboitiz family donated a six-hectare compound in Sitio Catitipan, Barangay Communal, Buhangin District, Davao City, where the construction of the first four buildings for the regional headquarters started.
The initial construction of buildings and infrastructure inside the camp in 1976 was under the supervision of BGEN HERMINIO N AHORRO, who was then the Commander of Task Force “Pagkakaisa,” stationed at the Davao City International Airport in Barangay Sasa.
Initially, there were only four buildings of the Command - The Regional Headquarters building, which houses the Command Group and the General Staff today, the Headquarters Service Company building, the Enlisted Personnel Barracks and the Headquarters Mess Hall. In 1979, thirteen more buildings were constructed including the seven barracks of the former 56th PC Battalion. Most of these buildings were constructed by the Engineering Brigade of the Philippine Army, with the use of prefabricated steel materials. Years later, twenty-nine additional buildings were constructed including two guard houses at the main gate, a basketball court, two tennis courts and two condominium buildings for Police Commissioned Officers and Police Non-Commissioned Officers assigned in the Regional Police Headquarters.
Today, the camp has a Cooperative building, Ammo Dump, Day Care Center, Children’s Park and Memorial Monument, RD’s Security Quarters and Firing Range.
On May 7, 2013, the camp is renamed as Camp Quintin M. Merecido, by virtue of Republic Act No. 10529.
