Transcript of HOW TO SCOPE AN ENVIRONMENTAL INVESTIGATIO

HOW T SCOPE AN ENVIRONMENTAL INVESTIGATION
*
GEOSPHERE ENVIRONMENTAL
Which Environmental Investigations are we dealing with?
Common Sense Principles of Assessment
The Pros and Cons of Scoping for a Developer
Scoping your own quotations:
present
The CPD aims to show clients how to scope their own quotations.
* from a clients
perspective
Preliminary Investigations
Desk followed by site based study into POTENTIAL contamination
Targeted on the most likely areas and types of contamination
Must be interpretive and not factual.
Cons:

Need knowledge to determine bespoke scope
Non bespoke scopes tend to be generic 'one scheme fits all' and may include unnecessary items
Consultants may have site / area specific knowledge
Scopes set by structural engineers or other party

Pros:
Like for like quotations possible with direct comparison of costs
Additional components can be added / components can be removed.
Helps stop consultant 'cheapening' works
Forces understanding of tasks involved
Helps plan works from the outset
At the preliminary stage - common sense prevails
hence 'targeted on the most likely areas and types' of contamination
This sites or features generally have the same issues
With adequate background knowledge assumptions can be made
Assumptions allow SCOPING to be undertaken
To scope your own quotations you need:

General common sense
Limited site specific data
General guideline of services available and what they achieve
SCOPE OF INVESTIGATION
1. Development
Current land-use on site
Historic land-use on site
Nearby land-use
2. Desk-based Risk Assessment
Risk posed by 1. VS Sensitivity of development
3. Underlying Geology
Superficial Deposits (cohesive / granular)
Bedrock Deposits (cohesive granular)
4. Size of Development
Small
Medium
Large
Supervision
Investigation
Reporting
Data search
WORKSHOP

QUESTION 1
WORKSHOP COMPONENT
Please Split into groups of 5 or so and as a group work out the answers to the questions.

Its not a competition............... yet
CURRENT SITE LAND USE
SITE A
SITE B
SITE C
SITE D
WORKSHOP

QUESTION 2
HISTORIC SITE LAND USE
SITE A
SITE B
SITE C
SITE D
WORKSHOP

QUESTION 3
Which takes precedent the current or historical land-use at a site when determining the risk?

So which is the 'worst' site?
WORKSHOP SCOPING EXERCISE
Using site D - we will now run through an exercise to work out a scope and approximate cost for investigation.
SITE D
1. Development
2. Desk-based Risk Assessment
3. Underlying Geology
Are Superficial Deposits cohesive?
Are Bedrock Deposits cohesive?
Local Environment Site Sensitivity?
4. Size of Development
Small
Medium
Large
Proposed Development is residential units with private gardens.

What sensitivity is the development?
High risk or low risk development history?
Proposed development is 4 residential units, what size development is this?
Now you have all the data to fit into a framework of services - See which elements you will need and as a group tick them off.
ANSWER:

Phase 1 Desk Study
1 x Day Window Sampling
Laboratory Testing (a little)
Gas Monitoring Well x 1
Site Supervision (1 day)
Gas Monitoring (6 visits)
Interpretative Report
Now you have a scope ->
You can also have a budget!
On the worksheets provided - select a team name and have a stab at pricing the specification.

Closest team wins prizes!
CONSULTANT TRICKS - QUOTE CHEAPENING
Anyone can produce a cheap quote.

The manner consultants 'cheapen' quotes is simple - by cutting the scope.

Look at the scope you just priced - how can you make it cheaper?

How lean can you go? Lets as a group shave the cost to £2100 approx - a more reasonable price.

Do you prefer that?

WOULDN'T IT BE GOOD IF SOMEONE HAD MADE AN EXCEL SPREADSHEET TO MAKE THIS PROCESS EASIER???

SOMETHING WITH PRICES AND SCOPES BUILT INTO IT????
THE ACTUAL VALUE SHOULD BE:
£4245.00
The team closest wins a prize!!!!
CHEAPENING:

Phase 1 Desk Study - £745
1 x Day Window Sampling - £650
Laboratory Testing (a little) - £250
Gas Monitoring Well x 1 - £100
Site Supervision (1 day) - £400
Gas Monitoring (6 visits) - £1200
Interpretative Report - £ 900

The site and what will be required stays the same
and is known at this stage. This leaves the client
thinking that either less is required or unknown at this stage.

£650
