Philadelphia, PA: sitework bid and jurisdiction guide
Philadelphia sitework estimating should start with the PWD review classification and accepted stormwater design. Earth disturbance, development type and the selected practice affect the scope documents; they do not justify copying a generic Pennsylvania detention allowance.
Jurisdiction boundary: Philadelphia Water Department development review; confirm the project classification and applicable state coverage.
Remote plan-based takeoff support; no local office, completed local project or site investigation is represented by this page. Cost, delivery schedule and deliverables depend on the agreed project scope.
Bid decisions to resolve before pricing
1. Establish development classification and plan revision
Source context: The PWD manual organizes applicability, submission and design guidance for development and stormwater projects. Read the agency resource.
Estimating application: Record the accepted classification, earth-disturbance limit and manual revision with the civil cover sheet. Ask the designer to resolve applicability instead of treating every redevelopment as the same stormwater package.
Clarification to request: What PWD review classification and accepted plan set establish the work in this bid?
2. Take off the chosen stormwater practice and supporting components
Source context: PWD guidance includes practice design alongside pretreatment, inlets, outlets and supporting features. Read the agency resource.
Estimating application: Trace excavation, storage, soil or aggregate media, underdrains, pretreatment and overflow individually. Compare component elevations against grading before pricing.
Clarification to request: Are maintenance access, pretreatment and outlet controls included or assigned to another trade?
3. Keep municipal stormwater and construction-stage responsibilities distinct
Source context: PWD maintains local stormwater regulations; state Chapter 102 documentation is a separate project review input. Read the agency resource.
Estimating application: Compare the PWD accepted design with construction-stage E&S plans. Flag duplicate basin excavation, missing conversion work or conflicting limits and obtain a written scope assignment.
Clarification to request: Does the construction-stage plan agree with the final PWD-approved system and restoration limit?
An underground facility sits below proposed paving
Illustrative Philadelphia quantity review; no universal required storage volume is assumed.
Measure the facility excavation using the designed footprint and elevations.
Separate aggregate envelope, storage components and utility connections.
Reconcile paving restoration with the facility work to avoid measuring the same pavement twice.
Facility installation and surface completion remain traceable in separate workbook rows.
Source documents and limits
Sources checked . The bid-review notes are our estimating interpretation of the linked resources. Confirm the contract edition, current amendments and project approvals before pricing.
A quantity takeoff records scope from supplied documents. It does not provide engineering design, a permit approval, a site investigation or an installation-ready machine-control model.
Documents needed for a Philadelphia, PA sitework takeoff
The project address establishes the review area, but the drawing set establishes the quantities. Put each of the following in a document register with its date, revision and author. Missing inputs should become a clarification or a stated allowance.
Input
What it resolves
If absent
Address, parcel and approving authority
Site limits, municipality, roadway and utility interfaces
Ask the designer to confirm jurisdiction; a postal city is insufficient.
Existing survey and proposed grading
Surface comparison, stripping and earthwork boundaries
Identify the missing surface; do not report a balanced site from plan area alone.
Geotechnical report and approved details
Undercut, material reuse, groundwater and conversion assumptions
Use a named, separate allowance pending design information; avoid county-wide soil factors.
Utility plans, profiles and sections
Pipe runs, depths, structures, bedding and restoration
List missing inverts, dimensions and connection limits for clarification.
Stormwater plans, permits and phasing
Temporary controls, permanent facilities, treatment and stabilization
Separate measurable installations from unresolved operating duration and responsibilities.
Bid schedule, specifications and addenda
Pay units, incidental work, exclusions and revisions
Keep measured quantities separate from unconfirmed payment assumptions.
Use the technical service pages for measurement methods and inclusions. The local guide identifies document and jurisdiction questions; the work package defines the requested deliverable.
Send the drawings, revision list and intended bid scope for a project-specific proposal. Price, schedule and file deliverables are confirmed after document review.
