−	The NPPF makes clear that '~~...~~there will be archaeological interest in a heritage asset if it holds, or potentially ~~may hold~~, evidence of past human activity worthy of expert investigation at some point. Heritage ~~assets with archaeological interest are the primary source~~ of ~~evidence about the substance and evolution of places~~, ~~and~~ of ~~the people and cultures that made them~~.'	+	The revised NPPF (February 2019) makes clear that 'there will be archaeological interest in a heritage asset if it holds, or potentially holds, evidence of past human activity worthy of expert investigation at some point. Heritage asset is defined as 'a building, monument, site, place, area or landscape identified as having a degree of significance meriting consideration in planning decisions, because of its heritage interest. It includes designated heritage assets and assets identified by the local planning authority (including local listing)'.

	The NPPF makes no distinction between archaeological sites and historic buildings, or between designated - i.e. 'Listed' or 'Scheduled' - or un-designated entities: all are referred to as 'heritage assets'.

−	Archaeological ~~Officers~~, in theory, perform an identical role to ~~Conservation Officers~~, but in truth they are very different and respond differently to development and building proposals.

Some LPAs employ a single person for both jobs, and others allow their archaeological officers to advise their conservation officers, and vice versa.

−	For archaeological sites, the LPA's ~~Archaeological Officer~~ will consult the HER and take a view as to whether the proposed development will affect archaeological remains. If they believe there is a reasonable risk of that, they will ask the applicant to provide verifiable information on the nature and significance of those archaeological remains. That can be done through a desk-study type report, but invariably the LPA will ask for that to be corroborated by some form of site investigation, so it may be more efficient to commission a site investigation immediately.	+	For archaeological sites, the LPA's archaeological officer will consult the HER and take a view as to whether the proposed development will affect archaeological remains.

	Archaeological site investigation is usually referred to as 'evaluation'.

Desk studies have value in their own right only where there is a need for due diligence, or where the desk study is likely to prove that there is no need for evaluation.

−	There are plenty of specialist contractors able to undertake 'evaluations', most with websites and yellow pages entries, and many are listed by the [http://www.archaeologists.net/ Institute for Archaeologists] (this is the trading name of the Institute of Field Archaeologists) which has been granted ~~Chartered~~ status. Evaluation is analogous to geotechnical site investigation (albeit with different trench configurations) and the costs, times and lead-in times are likely to be comparable.	+	There are plenty of specialist contractors able to undertake 'evaluations', most with websites and yellow pages entries, and many are listed by the [http://www.archaeologists.net/ Institute for Archaeologists] (this is the trading name of the Institute of Field Archaeologists) which has been granted chartered status.

	When an evaluation demonstrates that the proposed development site contains significant (which is a movable feast) archaeological remains that cannot be protected by redesigning the proposals, the LPA will attach a condition to planning permission requiring the archaeological 'excavation' of those remains.

An 'excavation' contract proceeds through three stages:

−	* (1) Site operations.	+	* 1 Site operations
−	* (2) Post-excavation assessment, which is a preliminary assessment of the academic value of the results and a proposed dissemination strategy, usually involving academic publication with an archaeological journal.	+	* 2 Post-excavation assessment, which is a preliminary assessment of the academic value of the results and a proposed dissemination strategy, usually involving academic publication with an archaeological journal.
−	* (3) Post-excavation analysis and publication.	+	* 3 Post-excavation analysis and publication.

−	The last two stages are carried out off-site once construction has commenced, but can run for ~~YEARS~~ on large or complex sites and will often still be running long after the defects liability period or even contractual liability period for the building works have expired. Post-excavation analysis and publication costs will often be between 30% and 50% of site operation costs. It is a tried and tested strategy that works well and most archaeological contractors are highly experienced in it.	+	The last two stages are carried out off-site once construction has commenced, but can run for years on large or complex sites and will often still be running long after the defects liability period or even contractual liability period for the building works have expired.

−	The process for works affecting historic buildings is slightly more complex, mainly because most ~~Conservation Officers~~ are not primarily concerned with the archaeological potential of historic buildings - or at least don't have the time or resources to do so.

−	That information is embodied in the layout, structure and fabric of the building and can be recorded and analysed archaeologically.

−	Where it cannot be preserved, a detailed record survey should be made. Invariably, that record survey can be made ~~ONLY whilst~~ refurbishment is underway, because it is not until finishes start coming off and demolition starts that the historic fabric can be observed and recorded. Accordingly, it is inherently difficult to cost in advance, but it will rarely cost more than a few % of overall construction costs and there are plenty of specialist contractors willing to do it.	+	Where it cannot be preserved, a detailed record survey should be made.

	Managed intelligently and with foresight, archaeology need not inconvenience any construction project. That often requires engagement with professional archaeologists at an early stage, preferably through the agency of an architect or designer with an established relationship with archaeologists. Some even employ their own.		Managed intelligently and with foresight, archaeology need not inconvenience any construction project.
