Which projects have unusually high allocation per meter?

The first tables compare each rate with the typical rate in the same official program and a similar stated-length group. A high-rate candidate is more than twice the typical peer rate and unusually high within its peer group. This is a scope-review queue, not a verified overpricing finding. Extreme values remain visible as individual points in rate charts. Printed segments under 10m remain in tables and CSV but are excluded from rate charts. Coverage denominators include all selected extracted occurrences in each category, including those without a usable length.

These are whole line-item allocations divided by stated segment lengths, not verified construction unit costs. Bridge chainage may cover approaches rather than bridge span. Missing percentage means no usable length was recovered from the current title/project context; it does not establish that the original budget or engineering documents omit length.

Roads and bridges · length, lanes and allocation density

Each project is a 3D block packed into a comparison grid: the long edge grows with project length, the crosswise width grows with lane count, and vertical thickness shows allocation per lane-meter on a log scale. Blocks are sorted by length within roads and bridges. Road lane counts use project text or matched inventory; bridges without a stated count use the same two-lane baseline. This is a screening comparison, not a verified construction cost.

Drag to rotate and zoom. Hover on a block for the project, exact dimensions, lane-count basis, allocation and source. Density thickness is logarithmic so lower and higher values remain visible. Projects without a usable length and lane-count basis stay in their tables.

Coordinate-based allocation per meter · approximation

Additional tables below divide whole allocations by straight-line separation between two printed endpoints. Separately labeled FMR segment chords are summed. A road can curve or include structures, so this distance is not a measured road or bridge length. These approximate rates are kept outside stated-length coverage, historical price comparisons and high-rate flags. Review flags, coincident endpoints, unpaired coordinate lists and mixed road/bridge rates are withheld. No distance between different projects supplies a project-length denominator.

Are stated-meter allocations higher than FY2026 GAA?

Compare the same official work program first, then comparable stated-length groups. FY2026 is enacted GAA; FY2027 is the HGAB 3rd-reading proposal. These are allocations per stated meter, not verified construction prices or a finding of overpricing.

Coverage and exclusions

Method and limits

Same length parser as current page; positive domestic DPWH OPERATIONS col_J occurrences only from local parsed FY2026 schedule. Peso amounts already in pesos. Official PAP joins use case/punctuation normalization only; unmatched programs excluded from peer comparisons. Lengths below 10m withheld from rate comparisons. Program medians need at least 20 usable records per stage. Length adjustment uses FY2026 length quartiles, at least 20 records per stage per band, and a FY2026-count-weighted mean of band median ratios. Unsupported bands are excluded, never extrapolated.

• Different projects and stage scope; not paired contracts or measured construction cost inflation.
• Surface, recorded condition, width, lanes, terrain, structures, geography and funded quantities remain uncontrolled in this cross-year table. Current-page surface/condition screening does not turn this into a matched-context historical comparison. Rates are whole allocation/stated meters.
• FY2026 column-J leaf scope can omit records at other hierarchy depths; selected coverage is not the complete DPWH budget. Missing metadata can bias comparisons.
• FMR is not compared here: this historical comparison reads the DPWH schedule only.
• Medians resist extreme-rate influence; no extreme individual rate dots or bars shown. No formal significance or causal claim.

Supporting length-group calculations

The adjusted percentage is the mean of the group rate ratios, weighted by the FY2026 record count. Only the groups shown qualify; omitted groups do not count toward the result.

At what stated lengths does allocation density change?

Length bands are compared within the same category and official work program. Allocation density is pesos per stated meter. A shorter denominator can raise this ratio without an unusually large allocation, so the tables also show total allocation and a separate model of allocation versus length.

These are exploratory grouping boundaries, not engineering price standards or evidence of overpricing. Sparse samples, missing lengths and unmeasured project scope limit interpretation.

Where median density changes by at least 2×

Only comparisons with at least 20 rows in each band are included. A ratio above 1 means the shorter-length band has higher allocation per meter. Bands with fewer observations remain in the complete band tables below.

Does total allocation show a length boundary too?

The segmented model fits log total allocation against log stated length within each PAP. It needs 80 records and 20 per side, excludes lengths below 10 meters, and requires BIC improvement ≥6 over a single slope. The boundary is selected from observed-length candidates, not a fixed 100-meter threshold; bootstrap frequency describes how consistently it is selected. The 10th–90th percentile of bootstrap-selected boundaries describes an empirical stability window, not a confidence interval. The ≥25-meter sensitivity boundary is also shown.

Complete length bands · separate categories and programs

These descriptive medians remain separate by PAP. FMR and bridge samples may be too sparse for breakpoint inference.

Method and limitations

Length bands are derived separately within each PAP using approximately equal-count groups (up to eight, targeting at least 20 records per group). Equal observed lengths stay together. Breakpoint candidates are geometric midpoints between adjacent observed distinct lengths, requiring at least 20 records on either side; up to 31 candidates cover the eligible boundaries. No 100-meter boundary is prescribed. The searched boundary counts as an extra model parameter in BIC.

• Density=allocation/length; declining density can follow mechanically from a fixed budget.
• Quantile-band counts and 2×/BIC screens are editorial exploratory choices, not calibrated corruption thresholds.
• Models use total allocation rather than density to reduce the arithmetic-denominator trap.
• Bootstrap votes measure selection stability in this sample, not the probability of a real engineering threshold.
• Dependence between allocation occurrences, unknown width/terrain/structures and non-random missing lengths remain uncontrolled.
• Sub-10m rows stay visible in bands but are excluded from model fits; ≥25m sensitivity is reported.
• Multiple exploratory program/boundary searches are not confirmatory significance tests; no p-values or multiplicity-adjusted claims are made.
• Sparse bridge/FMR data cannot establish an engineering threshold. No pooled cross-category rate model.
