DPWH Traffic Signal Projects: Scale and Procurement Context

The Department of Public Works and Highways funds and implements traffic signal installations as components of national road improvement projects, road safety programs, and urban road upgrade projects throughout the Philippines. These installations range from single-intersection signal replacements included as minor works in larger road improvement contracts to standalone multi-intersection signal upgrade programs for specific national road corridors.

For procurement officers, BAC members, and engineering staff involved in DPWH signal projects, understanding the technical specification requirements, approved product standards, and procurement documentation requirements is essential to ensuring compliant and effective project execution. This guide covers the key technical and procurement considerations for DPWH traffic signal projects, with reference to XINTONG product specifications supplied by Ultra Power Industrial Resources, Inc.

DPWH Design Standards for Traffic Signals

DPWH traffic signal installations are governed by the Highway Safety Design Standards and the Traffic Engineering Design Guidelines, which specify minimum requirements for signal head size, mounting height, signal face visibility, retroreflective backplate dimensions, pole foundation design, and conduit installation. Traffic signal controllers must support the phase sequences required by the intersection geometry and traffic volumes established in the traffic study component of the project design.

XINTONG signal heads are manufactured in 200mm and 300mm lens diameter configurations. DPWH guidelines specify 300mm signal heads for high-speed approaches and major intersections on national roads, and 200mm signal heads for lower-speed urban intersections. Both configurations are available from XINTONG with IP65-rated polycarbonate housings and high-brightness LED arrays meeting the luminous intensity requirements for daytime visibility in tropical sunlight.

Technical Specification Requirements for Bid Documents

DPWH bid documents for traffic signal supply and installation must include technical specifications that are written in performance or functional terms rather than brand specifications, in compliance with RA 9184 Section 18. Key specification parameters for DPWH traffic signal procurement include LED minimum luminous intensity by signal color and lens diameter, IP rating for signal head housing, operating temperature range, controller phase capacity, actuated operation capability, cabinet construction and IP rating, pole material and galvanization standard, and warranty period.

XINTONG products meet or exceed standard DPWH specification parameters across all of these criteria. Ultra Power Industrial Resources, Inc. provides DPWH district engineering offices and their consulting engineers with XINTONG technical datasheets and sample specification language that can be adapted for use in DPWH bid documents while maintaining RA 9184 compliance.

Approved Budget for the Contract and Cost Estimation

DPWH project engineers preparing Approved Budget for the Contract (ABC) estimates for traffic signal components of road improvement projects require reliable cost data for signal heads, controllers, poles, detection equipment, cabinets, and installation works. Inaccurate ABC estimates, whether too low or too high, create procurement complications: a low ABC results in failed bidding if no compliant bid falls within the amount, while a high ABC wastes appropriated funds and invites scrutiny from the Commission on Audit.

Ultra Power Industrial Resources, Inc. provides indicative price lists and formal quotations for XINTONG traffic signal systems to DPWH district engineering offices preparing ABC estimates. Our quotations include itemized unit prices for all system components, delivery costs to project site, and installation cost estimates based on intersection complexity, providing the detailed cost breakdown required for DPWH cost estimate preparation.

Delivery, Installation, and Commissioning Requirements

DPWH traffic signal contracts typically include supply, delivery, installation, testing, and commissioning as a single scope of work, with the contractor responsible for the complete intersection package from equipment delivery to system handover. XINTONG’s factory provides batch delivery capability for multi-intersection projects, allowing complete equipment sets for all project intersections to be delivered on a coordinated schedule aligned with the contractor’s installation program.

XINTONG provides installation and commissioning support including factory-pre-configured controllers, wiring diagrams, installation manuals, and commissioning test procedures. Technical representatives are available for on-site support during commissioning of complex intersections or at the request of DPWH project engineers for quality assurance purposes.
